i'll be running a wideband as well, as an extra safety measure/backup for the ethanol sensor - i'm confident in the sensor, but it's a new setup, so i don't want to rely on anything 100%. as for knock, it's running on high % ethanol, what's knock?? but seriously, it's such a decreased concern on e-flex/e85 that i don't envisage running a knock sensor. ethanol sensor wideband and above all, a fantastic tune by someone who excels at his craft.... that's a lot of 'safety' right there IMO - if anything, i've got more monitoring going on than most poeples setups (ie, pfc with 98 tune with no knock control, you're just relying on the tuner there and that's it)

thanks heaps for the replies guys!, exactly what i was after!! i'm liking the Oakley's and Sparco's on the autosport site at the moment, the mid boot type is appealing to me. There's some Oakley Karts on ebay, but different to the ones at oakley.com, maybe last season. Oakley ones have "self extinguishing suede" as well lol, at least my feet will be ok in the event of a fire The Puma's are a bit......... i dunno... just reminds of the Ferrari driver at one of the driver dynamics days that had matching red ferrari puma's....., but then again, if Puma had GTR shoes... hahahah so yeah, i'm thinking mid cut, oakley or sparco.... feel free to add any others to the mix if there are some other good ones out there

dooooo eeeeeet Ham! (after selling the PFC first, then throw it in the bin , then get a G4.... you know, like a G6, like a G6.... but 4) Don't quote me on this, but i think Racepace may have even used a standard GTR pump on tangomatt's 2.8 Vcam build, which ended up around 420rwkw on 98 - it could be a nismo, but certainly only a single drop in - i know it's not E85, but if they managed that on a standard pump, then a tomei/nismo being bigger again surely should be good for most of us wanting to go E85 on upgraded turbo Rb26's We'll know soon how we go with a single intank nismo on a true blue E85 (Powerplus) but as Trent has already said, he's had a Tomei up around the 400-420rwkw mark on a uprgaded turbo 26 without an issue, you're going to have no issues with 2 of them!

i was thinking perhaps Jetspeed, they were involved in the Just Car 34

^ you mean the other way around yeah? EDIT: did i just fail in internet sarcasm

looking to get a pair of nice driving shoes - don't need to be FIA approved etc, just something with like a rounded rubber heel, and quite fitting would prob do the trick. i'm guessing Puma has some options, but any other brands to check out? cheers, daniel

probably any decent tuner could tune a Link - or just find someone who tunes the rebadged ones (Vipec)

I was going through this big logistical exercise on surge tanks, twin bosch this, under-car surge that... but when i had a chat to Trent and Racepace, they both thought the single Nismo might be up to the task and leave it for the time being. Suits me, saved a stack a cash!! hahah lol - And when this is all sorted, i hope this will resolve a few headaches for people in the same boat. Built 26 with 2530's (or for a lot of people -5's) might only need 1000cc's and a good intank, and that's it. If that is indeed the case, a lot of you guys'n'girls will probably only need to change injectors and that's it. Pretty simple really But for you, 2 x Nismo sounds like heaps!! I think people might be going overboard with fuel setups. What's the rest of your setup like? I should clarify, the first E-flex tune was done BEFORE the sensor was in etc, we had a few obstacles to get around with the install, but Trent sorted it all out. So we're not 100% sure of the EXACT ethanol % on the base E-Flex tune, but as i said, judging from our tests with Springvale and Glen Waverley, and the low'ish # we got (+30rwkw) it seems like the first tune may have been perhaps E60. I have a full tank of Springvale E-flex in at the moment, and will know for sure in a week or so. Everything is tuned on the conservative side at the moment as well. The powerplus E85 will give us the benchmark and our first run next time will tell us the exact % of Springvale. As for the wideband, i'm not 100% if direct in or 0-5v, will confirm that. Actually, i might see if i can get the software on my laptop and i can check the E% for everyone Linkems: Ironic username - I haven't even touched the other features yet, anti-lag, launch control etc - and really, only a few hundred more than a powerfc, it's a fantastic ECU. The other thing for me when i bought it was supporting a Christchurch company. I know it's not Australian, but i was in NZ earlier this yeah and Christchurch is really hurting and unfortunately Link lost their HQ in the earthquake - I was more than happy to buy from them, as the whole city definitely needs a bit of help

Paul, check my thread mate, it may be of some help built 26, HKS 2530's, ID1000's, intank Nismo, E85, everything is sweet - pretty simple in the end

thanks for the fantastic response guys!! I was listening to House of Reps the other day, and it looks like Ethanol will still be excise free for another 5 years (i think it might have even been 10 years) Which is obviously good news for us disco - i have embarrassingly little knowledge when it comes to.... well, most things car related but all i know is that you need 2 base tunes, 98 and E85. That's it, Trent hasn't tuned anything else, but setup the extrapolation in between. Obviously running winter E-Flex i really only have a 98 and E70 tune at the moment, but in the next couple weeks, we'll get the real deal E85 tune done (powerplus) and then have things a bit more spot on. I forgot to mention, I will also be running a wideband setup to monitor AFR's - the Seimens sensor should be good for quite a few km's. Trent thinks it might be a bit of a consumable item, but we're talking tens of thousand of km's, so nothing to really worry about there. But being a new setup, i want to have a back-up parametre for the ECU, so the AFR will be monitored by the ECU as well Scotty, add about $30 usd (i think) from the Zeitronix price on the website, so that's about $380 USD, a touch cheaper with the aussie at the moment, so you're about right Guys, if you don't want to spend that much money on a sensor, the Zeitronix website has a list of cars with that particular part (Factory). If you have access to US wreckers, you could probably pick it up for like $20-$50 usd. I wasn't going to go second hand considering it hadn't been done before, and wanted to take out as many variables as possible, so everything started new. As for the humble, albeit fantastic, ECU that is the PowerFC, it may not be suited for this application But i'll let Trent correct this if need be. The sensor outputs a digital signal, a frequency where between 50hz and 150hz = Ethanol percentage. The wave form is able to give both E% and Fuel temp (both of which the Link G4 can read) - You can buy the digital to analogue converter from Zeitronix, but it's an all-in-one unit that has the E% display. About $170USD, which isn't too bad. This will then output an ANALOGUE signal of 0-5V, which might bring some more ECU's into play. The next test to come is to make sure on full noise and a mixed tank, everything is changing fast enough. Oh, this is a PLUGIN G4 everyone, not a full-on wire in G4 Extreme. I believe it cost me $1300 from Rob, a few hundred more than a powerfc but a whole lot more ECU. I HIGHLY recommend this option to anyone. There's a plug-in version for most of our cars And for all the rebadged Link owners i'm assuming you guys are good to go with the exact same setup If you have Vipec's, they're probably tuned by Trent anyway (for Melb), so just grab all the parts, take it to Chequered and ask "one Flex-Fuel car please" Trent did say he should be able to replicate the setup on most cars, so shoot Chequered an email and see how you go cheers, daniel

Vid 3 Trent putting in some Springvale E-Flex. This is where it gets interesting. We max out at E60 with the Springvale E-Flex and it actually settled at around E57 i believe in the end. Yes, it's not a perfect test with some 98 in there, but it was only around 5-7 litres - we did 20L litres of Springvale E-flex in addition to the Glen Waverley E-flex that was already in the tank (over a quarter tank). The car ended up 3/4 full with out 5 litres or so of that being 98, and it ended up mid E55-E57 - I just filled up with Springvale E-flex tonight, and will only use Springvale until i'm back at Chequered, and we'll get a definite answer then. Even though this "only" resulted in 387rwkw, it's still stupid fast lol - the Powerplus E85 will be interesting...

It what i think may be an Australian, possibly world first for a GTR, Trent @ Chequered Tuning (formerly Status Tuning) has managed to turn my R34 GTR into a genuine Flex Fuel car I can now run my car on ANY mixture of 98 unleaded to 100% E85, with constantly updating maps depending on the mix in the tank. Mega f*cking happy days! This is something i've wanted to do for a while now, and i know there's been quite a bit of talk on the forums about this, so i know this will be of great interest to some of you. We all know the benefits of E85, heap of extra power and torque, greatly decreased risk of detonation, lower temps in some areas, less-to-no carbon build-up AND perhaps most importantly, greatly reduced emissions coming from a renewable fuel source Win win win win win (especially when in Australia we make our ethanol predominantly from crop by-product, very sustainable) Despite all the pluses for E85, there are invariably some draw-backs, the main one is availability and what seems to be the main hurdle for most people. Prior to Caltex, Melbourne only had two outlets. United @ Hoppers Crossing, and Fueltown @ Southland, but unfortunately due to the floods in Vic and Qld, the crops that allow the ethanol to be made were wiped out; no crops = no by-product = no ethanol Consequently, United and Fueltown has been out for a few months and probably a good few months more to go (hopefully they get it back online once the crops come back). But Caltex has overlapped and now filled the void with their E-Flex - stated by Caltex to be E70% to E85% depending on the time of year, and this time of year definitely means E70% (but perhaps not even that high, read on...) What i was hoping to achieve with this exercise was to prove that it needn't matter what fuel you were running, how far your closest E85 outlet was, what fuel map was loaded, avoiding filling up at Hoppers because you tuned on Fueltown, avoiding filling up at United or Fueltown because you tuned on E-Flex and vice versa, or just worrying about the varying E% and consistency - i didn't want to have to worry about any of that. I just wanted the FLEXibility (oh dear) to fill up with ANYTHING from 98 to any E85 option without having to drain fuel, change settings on a hand controller, pull out the laptop at the servo etc etc... So i discussed things over with Trent @ Chequered Tuning and let him know what i wanted to do, he reckoned he could give it a crack and had a few ideas how to do it, and advised on how to proceed. For those playing along at home you will need - 1 x uber tuner (see Trent) - 1 x Ethanol Content Sensor (GM Part, made by Seimens. I purchased mine from zeitronix.com - SENSOR) - 1 x wiring harness from sensor to ECU -or- to Digital -> Analogue ethanol content analyser - found here (there may be a locally sourced ACDelco part for this, i'm checking that out) - 1 x Link G4, beast of an ECU and thanks to the lovely people at Link, already have allowed for the ECU to take the raw digital signal from the content sensor without the need for some mid-way converter to change it to 0-5v signal. Thank you Link! - 1 x Link G4 extra wiring harness (the digital input is in this part!) - 1 x somet-a-rather Ohm resistor to make sure the ECU and the content sensor talk properly - Some extra fuel lines, braided lines, fittings etc to hook up the sensor to the fuel lines. - 1 x car Take all those, and you get a car that can now fill-up with anything between 98 and E85, AND fill up at ANY "E85" outlet, regardless of brand. This seems to be even more important now as unfortunately, Caltex may give you E60(or less) to E70 at the moment. We still have to finalise everything, but here are initial tests done with the setup for the first time.. Vid 1 is Trent pouring in some 98 ontop of some Glen Waverely E-Flex currently in-tank. The Glen Waverley E-flex was bang on E69-E70. As would be expected the E% drops Vid 2 shows the ECU altering the ignition timing in response to the E% :smokin: Vid 3 is Trent putting in some Springvale E-Flex. This is where it gets interesting. We max out at E60 with the Springvale E-Flex and it actually settled at around E57 i believe in the end. Yes, it's not a perfect test with some 98 in there, but it was only around 5-7 litres - we did 20L litres of Springvale E-flex in addition to the Glen Waverley E-flex that was already in the tank (over a quarter tank). The car ended up 3/4 full with out 5 litres or so of that being 98, and it ended up mid E55-E57 - I just filled up with Springvale E-flex tonight, and will only use Springvale until i'm back at Chequered, and we'll get a definite answer then. (i'll put in 2nd post) This explains the less than spetacular numbers we got when Trent tuned from 98 to E-Flex for the first time 357rwkw on 98 to 387rwkw on E-Flex (i provided Springvale E-flex) - So unfortunately, it "seems" even E-flex can vary between stations OR all E-flex can be less than 70% this time of year, and it just happened Springvale was the place i filled up. I'm thinking the latter more than the former... it's got to all be delivered from the same truck/company etc +30rwkw is great, but on some TRUE E85, i'm hoping we can crack 400 - Soooooo, i went and bought a drum of Powerplus E85 - 100% guaranteed real deal E85 (mixed with 98 i believe). We will drain the system, run up the Powerplus and get our baseline E85 reading. I know United and Fueltown E85 sometimes ran higher, E90 etc, so when those come online we'll do some more testing and the car will have broader parametres to work off So it's been done. The content sensor that has been linked so many times in the E85 threads has been installed, hooked-up, altering fuel maps and it's happy days Time to acknowledge those that have helped me and will no doubt be able to help you guys should you wish to give this a go (in no particular order) - Rob @ RIPS NZ; we all knows these guys, uber engine builders, makers of so many drool worthy things. Rob provided the Link G4 and extra wiring harness (you NEED this!) - Racepace Motorsport; made the bracket for the sensor and found a nice spot to mount it + being the usual great workshop we've come to expect (servicing/mechanical undertaken there, fantastic work as usual, thanks guys) - Zeitronix for the sensor and wiring harness, - TuffCarParts for the injector help (getting the ID1000's to fit my fuel rail and coming up with a MAP sensor last minute when the one i had acquired was DOA) and last, but definitely not least... - Trent @ Chequered Tuning I've been a customer of Status/Chequered Tuning for... 4+ years maybe? from the GTT and now to my GTR, and there really is just no other place i would ever take my car to get tuned. when it comes to tuning, in my mind there is only one place to go. It's all they do now, 100% tuning, it's the speciality, and it shows. Trent is meticulous with his work and not only came up with a great install for the sensor, but even helped me choose the parts as i don't really have a clue when it comes to 'engine bays' and making sure everything ties in, has a theme etc. But the end product with Trent's help basically makes it look like it's something Midori themselves had installed when building the car. It's neat, clean, ties in perfectly with the engine bay and looks trick too Trent even special ordered this wiring sheath from the U.S. to match the same stuff used for my Okada project ignition wiring. I really cannot recommend Trent/Chequered Tuning enough, the care taken with the car, the quality of the tuning but i guess most of all, just a unyielding willingness to do the job right. Sounds simple, but is unfortunately lacking in some workshops here. The sensor install As for the fuel setup, the other big q people have, i'm running genuine ID1000's and a Nismo intank pump. No twin this, surge thank that etc - just one intank and some bigger injectors. I thought i needed this big fuel setup, but both Trent and Racepace said that the Nismo might be up for the job and not to change it yet We'll know for sure after the Powerplus E85, but if it can go this far, i think we're good. So those worrying about fuel supply, don't. Big enough injectors, a good intank, and you're ok Sorry for the essay, but it's something i'm excited about (for environmental and performance reasons) and hope because of this, more people jump on board with E85. The more people use it, the more we'll see of it, and that can only be a good thing. Especially when the waste plant ethanol project gets kicked off. Exciting times people Thanks again to Cat + Trent cheers, Check (if you live in usa): Kroger Weekly Ad, or Myer catalogue.

if the story went as you described, i'm thinking it's not the original place i was thinking of... not naming names, but was this place recently involved in a high profile car insurance company build-up, which the car was available to be won via competition?

is that the exact same pattern at the Nismo ones?

^ may i ask where you got your RWC done and did you ah.... 'replace' anything to get the rwc?

^ this find one with the basic mods first, you'll almost certainly do them anyway - - nice set of rims - turbo back exhaust - FMIC (i would go a return flow FMIC as no holes will have to be cut, standard airbox can be kept etc etc a lot more stealth) - ECU of some sort - some suspension mods (swaysbars are great pieces of kit, but coilovers are cheap-as these days with a bunch of brands to choose from, so shouldn't be too hard to find one with coilovers done) but definitely check the for sale section on SAU, as quite often you can get a good history of the car which you can follow-up with a state roads, etc and also more likely to have someone own the car that actual cares for it, ie more of an ethusiast good luck

first offence != 30day impound does it? and is that ANY hoon offence? isn't practicaly anything a hoon offence... like talking on your phone?

1 week is not a massive delay, and when it comes to panel beating, i would not be worried at all about that sort of time-frame not that this situation at all warrants this, but you wouldn't go to VCAT, it would be consumer affairs first and then VCAT. what was the orig quote price and what was it bumped up to and why? PM shop name and i might be able to help out

bosch twin aero is what i used on my GTT, great wipers.... 100% recommend they look much better too and last for ages - i never changed them for as long as i had the GTT and they worked just as well at the end as they did at the beginning i also clay/polish/wax or sealant my windscreen as well, can never have too much sheeting action on glass

everything is gone, thread can be closed.

SAU price? or is that no longer?

hmmmm... i'm pretty sure you'll find most people like the inlet moved on a few more degree's than that -should be able to pick up 300-400 rpm better response with the inlet advanced and without really any top end loss if you've got adj cam gears, i'd have a play, you might have a bunch of midrange you're missing out on

nope, just because those items are made by HKS, they certainly don't 'need' a HKS ecu for them to work properly... hehe, a dump pipe is just a pipe - boost controller (evc 5/6?) is setup on it's own anyway changing to a good ECU's, with a good tuner, will have everything running just as well as the HKS one - but don't change if you've got a few options to tune - unless you can make some money selling the HKS and switching to something else

most people get 380rwkw on -5's at 20psi? bit high wouldn't you say? - i had a dig through the rb26 dyno thread for 2530 results and from what i could tell, around the low 20 psi mark, 21,22,23 people were making 350-360aw/rwkw - which i thought was about spot on for the 2530's? on 3 different dynos i've had 358, 353 and 357 around 21psi

TIN?
