It all comes down to what outcome you want from your vehicle.

Nistune around $450 mark.

Vipec $2500-3000 mark.

You do the math's.

Putting these two ECU's together is like saying, I'll race you in my R34 GTR when you own a S13 Ca18, you cannot compare them.

Bang for your buck, nistune, however you will out grow it if you want to make big big power.

How nwill you outgrow nistune, when the japs have been using th esame principle to make 1000hp. For the cost of the vipec, which is totally overkill for your setup, i would go nistune, buy your own wideband and have a crack. Or go nistune and take it to sydney/canberra. If your guy cant tune nistune then i wouldnt trust him with your car even if its a vipec. Remember even with the vipec it could still run like crap, as its only as good as the tune.

psymon, I think I recall tuning your old setup in canberra?

have you changed injectors or afm? are you still running the stock 270cc injectors?

Yeah you did a couple for me in canberra. The last one you did was to suit gtr injectors and was a great tune. :) Still gtr injectors, but i now have a z32 afm to put in one weekend.

As for the tuner, it's not that he can't tune a nistune, its more that he's never done one before but he's done multiple vipecs. I'm sure if i turned up with a nistune he could tune it, he's built tuned many respectable cars (including his own which was featured in the latest series of blood sweat and gears). It would just be reassuring with the vipec knowing it's not the first he's done.

I was intending to go with Nistune on a >300rwkw 26/30 but figured that after $450 for the ecu, $700 on two Z32s and $650 on a good ebc I was over the cost of the Vipec board + mac valve. Even with one Z32 it's close in cost. I don't have to worry about AFMs, and also get overboost protection and some other features.

It was the $ and overboost protection that made my mind up. And if your tuner likes Vipec it's also a plus to stick with that, although for a 5 hour trip to Sydney I'd say (having had 2 Vipec tunes, one of which was by a proclaimed Vipec specialist, but neither of which was very good) go to Hitman in Penrith, leave it for 2-3 days, pay your $1250 and come away with a great tune - power and driveability - as well as emissions certification.

Just my 2c.

Go with what your tuner says...

I don't know Nistune (is that just re-tuning the standard ecu?) but I know vipec... as much as I want DiRT Garage to shut the f**k up about it, it's still a very good ecu...

no need to be a c0ckhead Doof.

Im about to go Nistune in my S13...better than Power FC...Nistune has knock control.

If you have the bucks go Vi-PEC especially if your tuner is familiar with them.

Yeah Doof, cut it out. We dont need 2 cockheads crappin on about ecu's :laugh:

How much is big big power?

It would be safe to say 90% of users on here have stock motor internals so there max power goals are going up to be a approx max of 280-300rwkw.

Will the Vipec or any other full stand alone ecu have a noticable difference over the Nistune for these power levels?

The Vipec has a long list of extra features, but will they be used or needed for a daily driven street car?

Can some list what these great extra features any stand alone ecu have over the Nistune to justify the extra exspense?

ps. I have done a fair bit of searching on here about the pro's and cons of either ecu option. Generally everyone says one is better than the other, but do no state why to back their claims. There is one very well respected tuner on here from Melbourne that tunes more than one brand and agrees the Nistune is the best option for a Neo rb25 for the street)

if that is your intended mod list, nopoint spendingbig bux for vipec,

look at power FC or even cheaper option, the emanage blue or something.

im sure he can tune the emanage,

to tune the nistune, he needs to get the licence & software to do it.

^ its like neons on your car, unnecessary but just cool to have it :laugh:

the "great extra features" are launch control, anti-lag, flat shifting, Map sensor instead of AFM (though it will take an AFM if you want), built in boost control with the addition of a solenoid, onboard data logging, dual fuel and ignition maps with real time change over (you wire in a switch to do so)(E85/other fuel tune and your standard 98 tune for example).

There are probably other things i have missed but they are the main ones that come to mind.

Nearly all of those features I would not need or use. . . . already have a z32 and ebc.

Do not get get me wrong, I will be more than happy to hand over the extra $1000 if there is going to be a real noticable benefit.

psymon,

I have another idea that might help. I would be more inclined to make the drive to sydney and make a weekend of it. there are some top tuners there and you can choose either nistune or vipec there. nistune will do a good job for what you are looking for.

if you need a map to drive the car to sydney safely with the z32 installed and your other bits I can burn one and send it to you.

cheers...

Thanks for that. I'll keep it in mind in a couple of weeks when i have to make a decision.

that is included in the price of the board (well single user licence anyway). $200 for the board and $200 for the licence. so you are looking at $400 plus tuning. so even if it costs you $1000 in tuning you are still coming out ahead of just buying a vipec

  • 2 weeks later...
when fitting a vipec where do you place ther air temp sensor also is it wired independently

in the plenum or inlet piping. it is wired to to one of the temp. inputs. In a GTR it uses the factory sensor but cars like a gts-t that dont have an inlet temp sensor you have to use the sensor provided with the ECU.

My tuner can use an emulator and write/tune the factory ecu. The process is similar to Nistune, but doesn't require the Nistune daughter board. He still has to

-open the ecu,

-remove one of the processor chip,

-put it onto a reader and copy the complete firmware,

-transfer the program to the laptop,

-hook the laptop to the factory computer (where the chip was),

-tune the car,

-then write the file to the removed processor chip,

-resolder the chip back to the factory ecu.

This method retains all of the factory safety parameters e.g. knock control, over heat etc but also can adjust the factory boost solenoid (and possibly the MAC valve).

I think Dave @ Silverwater Automotive Service in your state can do the same thing.

I would expect the Nistune can adjust the factory boost controller (or a mac valve) too. So you can save the money by selling your boost controller.

I've got no problem with either ECU as both if tuned properly will deliver the same power and drivability. Dont let the knock control of the std ECU sway your judgement as from what I've seen it doesn't work very well at all. Thats why I'm thinking a Speed Density Visteon ECU with two knock sensors is what I will use if I ditched the std ECU.

easy

spend the dollars on a second hand pre-remapped RB20 ECU from japland

plus add in a safc

then tune tune tune, retune to be safe, and you'll love the bang for buck outcome that a remap + piggyback gives you :bunny:

or go NISTUNE and get the bloke to do it anyway - he's got to crack his cheery sometime !!!

my options:

a) remap + piggyback

b) nistune

    • Thanks, I removed the fuse and the relay from the car and made my own circuit with them to test them with a test bulb.  I will look for the wiring diagram and go from there.
    • Jdm DC2R is also nice for a FF car compared to the regular hatches of the time.
    • Now that the break-in period for both clutch and transmission is nearly over I'd like to give some tips before I forget about everything that happened, also for anyone searching up how to do this job in the future: You will need at least 6 ton jack stands at full extension. I would go as far as to say maybe consider 12 ton jack stands because the height of the transmission + the Harbor Freight hydraulic platform-style transmission jack was enough that it was an absolute PITA getting the transmission out from under the car and back in. The top edge of the bellhousing wants to contact the subframe and oil pan and if you're doing this on the floor forget about trying to lift this transmission off the ground and onto a transmission jack from under the car. Also do not try to use a scissor jack transmission lift. You have to rotate the damn thing in-place on the transmission jack which is hard enough with an adjustable platform and a transmission cradle that will mostly keep the transmission from rolling off the jack but on a scissor lift with a tiny non-adjustable platform? Forget it. Use penetrating oil on the driveshaft bolts. I highly recommend getting a thin 6 point combination (box end + open end) wrench for both the rear driveshaft and front driveshaft and a wrench extension. These bolts are on tight with very little space to work with and those two things together made a massive difference. Even a high torque impact wrench is just the wrong tool for the job here and didn't do what I needed it to do. If your starter bolts aren't seized in place for whatever reason you can in fact snake in a 3/8 inch ratchet + 6 point standard chrome socket up in there and "just" remove the bolts for the starter. Or at least I could. It is entirely by feel, you can barely fit it in, you can barely turn the stupid ratchet, but it is possible. Pull the front pipe/downpipe before you attempt to remove the transmission. In theory you don't have to, in practice just do it.  When pulling the transmission on the way out you don't have to undo all the bolts holding the rear driveshaft to the chassis like the center support bearing and the rear tunnel reinforcement bar but putting the transmission back in I highly recommend doing this because it will let you raise the transmission without constantly dealing with the driveshaft interfering in one way or another. I undid the bottom of the engine mount but I honestly don't know that it helped anything. If you do this make sure you put a towel on the back of the valve cover to keep the engine from smashing all the pipes on the firewall. Once the transmission has been pulled back far enough to clear the dowels you need to twist it in place clockwise if you're sitting behind the transmission. This will rotate the starter down towards the ground. The starter bump seems like it might clear if you twist the transmission the other way but it definitely won't. I have scraped the shit out of my transmission tunnel trying so learn from my mistake. You will need a center punch and an appropriate size drill bit and screw to pull the rear main seal. Then use vice grips and preferably a slide hammer attachment for those vice grips to yank the seal out. Do not let the drill or screw contact any part of the crank and clean the engine carefully after removing the seal to avoid getting metal fragments into the engine. I used a Slide Hammer and Bearing Puller Set, 5 Piece from Harbor Freight to pull the old pilot bearing. The "wet paper towel" trick sucked and just got dirty clutch water everywhere. Buy the tool or borrow it from a friend and save yourself the pain. It comes right out. Mine was very worn compared to the new one and it was starting to show cracks. Soak it in engine oil for a day in case yours has lost all of the oil to the plastic bag it comes in. You may be tempted to get the Nismo aftermarket pilot bearing but local mechanics have told me that they fail prematurely and if they do fail they do far more damage than a failed OEM pilot bushing. I mentioned this before but the Super Coppermix Twin clutch friction disks are in fact directional. The subtle coning of the fingers in both cases should be facing towards the center of the hub. So the coning on the rearmost disk closest to the pressure plate should go towards the engine, and the one closest to the flywheel should be flipped the other way. Otherwise when you torque down the pressure plate it will be warped and if you attempt to drive it like this it will make a very nasty grinding noise. Also, there is in fact an orientation to the washers for the pressure plate if you don't want to damage the anodizing. Rounded side of the washer faces the pressure plate. The flat side faces the bolt head. Pulling the transmission from the transfer case you need to be extremely careful with the shift cover plate. This part is discontinued. Try your best to avoid damaging the mating surfaces or breaking the pry points. I used a dead blow rubber hammer after removing the bolts to smack it sideways to slide it off the RTV the previous mechanic applied. I recommend using gasket dressing on the OEM paper gasket to try and keep the ATF from leaking out of that surface which seems to be a perpetual problem. Undoing the shifter rod end is an absolute PITA. Get a set of roll pin punches. Those are mandatory for this. Also I strongly, strongly recommend getting a palm nailer that will fit your roll pin punch. Also, put a clean (emphasis on clean) towel wrapped around the back end of the roll pin to keep it from shooting into the transfer case so you can spend a good hour or two with a magnet on a stick getting it out. Do not damage the shifter rod end either because those are discontinued as well. Do not use aftermarket flywheel bolts. Or if you do, make sure they are exactly the same dimensions as OEM before you go to install them. I have seen people mention that they got the wrong bolts and it meant having to do the job again. High torque impact wrench makes removal easy. I used some combination of a pry bar and flathead screwdriver to keep the flywheel from turning but consider just buying a proper flywheel lock instead. Just buy the OS Giken clutch alignment tool from RHDJapan. I hated the plastic alignment tool and you will never be confident this thing will work as intended. Don't forget to install the Nismo provided clutch fork boot. Otherwise it will make unearthly noises when you press the clutch pedal as it says on the little installation sheet in Japanese. Also, on both initial disassembly and assembly you must follow torque sequence for the pressure plate bolts. For some reason the Nismo directions tell you to put in the smaller 3 bolts last. I would not do this. Fully insert and thread those bolts to the end first, then tighten the other larger pressure plate bolts according to torque sequence. Then at the end you can also torque these 3 smaller bolts. Doing it the other way can cause these bolts to bind and the whole thing won't fit as it should. Hope this helps someone out there.
