They look "odd" because E85 typically needs "30%" (give or take) more fuel than 98. In the real world its actually a little less. They also need 30%, all over the rev range. It does differ a little under load (otherwise it would be 30 in every cell!) but not from 19 to 43%. Yours goes from 19% under low load, to 43% under full load. In addition to that, your tables imply that you add 133% of the correction when you have 80% ethanol in the tank. This would mean it would be 133% of 43%. 20% is too little and your E85 would be dangerously lean. 43% is too much and this means either your E85 map is fine (and your 98 is too lean) or your E85 is too rich. Note: The above numbers are when 100% of the correction is being applied to a decent base map. However.... yours is 133% of the numbers applied!. 133% of the correction being applied means that everything is 'out' even further'. The numbers are impossible numbers, it can't be correct, unless something is making it be correct, which is what the O2 WB does, it adds and removes fuel to try and hit the target on the "Target AFR" map, which is basically closed loop fuel control. The Target AFR map doesn't appear to be too bad as it's looking for 12:1 AFR under full load. It is common/advised practice to have the base map as accurate as possible, and not have an O2 controller have a monstous effect, though the Haltech lets it apply up to 25% more or 25% less fuel if need be. If this fails for any reason you are going to have a bad time if it is set up this way.

Other than the curvature of the earth, they are kind of all valid points But yes O2 gauge is kind of needed, everything else seems "fine" If you wanted to get real creative you could measure your VSS against time, to see if you were really slower between two specific points/runs. This however would require the problem to be reproducable at will. Or at least happen while you are logging it. Note: I didn't see the boost actually hit the limit of what the ECU is seeing at all. MAP pressure was all 21.5ish points, when it goes over the limit it will just flatline at 22.8 or w/e it is. The graphs do not show this.

I wouldn't even do it if the price differential between the two was 10K.

Also 44% more fuel is massive, 133% of 44% more fuel is obscene. The numbers just look... wrong? The stoich values of 98 and E85 are too different surely for both the 98 tune and E85 tune to be right at the higher end of that scale. Either the 98 base tune is dangerously, dangerously lean, or the E85 is horrifically rich. Now keep in mind, if you have the O2 sensor running and the controller doing its thing, it is possible for these correction maps to be really far out, and the O2 controller will do what it can to adjust. This may be the reason the car has bad E85 economy if it cannot actually trim enough up top. What is your AFR under load on E85 anyhow, what does the Haltech say/does it show in the onboard logs?

And fuel compensation scalar. It basically defines how much of the fuel compensation table is applied. Note: It is not linear!

IT is all about ability to learn, not what you know. At least that's what I care about. Souce: Worked in IT since 1999

The RB26 tax on that build was unreal. Two in a row asking for 28-30k for an engine. Maybe I'll put 26 rocker covers on it and up the price by 15K. Throw in some free VCT or something.

Feel free to buy my RB28 instead Birds, lol.

... 1) isn't the answer because Lith asked two different things.. What is controlling boost/map pressure/load when you are driving around on the street? You can't really tune over what the ECU is seeing, unless you fudge the numbers and have the same timing/fuel at 24psi that you do at 21psi. This is really very bad for both possible boost settings, or it's perfect for one of them, and really bad for the other one. There is an argument that when it's set to 24psi you are never at 21psi at 7000rpm, or at 21psi at 5000rpm, so you can use those cells on the map to tune for 24psi but.. yeah... The best way to test this is actual testing, to confirm whether it's in your head or not. Phone app of some sort would be ideal to do a few back to back runs on a deserted (private) road. Especially if it "feels bad". Cars aren't ever truly intermittent.

Trust me when I say weird shit happened and I had to end the day early But less earlier than normal!

It rustles my jimmies that adding 10% ethanol brings 91 down from say $1.25 to $1.20 But if you add 85% of it, the price is suddenly $1.39.. Can I buy the ethanol they're putting into the E10? It's clearly cheaper than the 91...

If you want to talk depreciation, have a look at the V10 M5's... Just buy three of them for your 90k budget

It's always 30-35% less range than equal driving on 98 If you really want to get sad, get a high stall torque converter, and then take *that* to the track! When I was running my engine in, I managed to pay United something like $770 of fuel in 5-6 days. Nowadays I am back on 98 because United's violent price gouging rustles my jimmies.

+1 (or 2, or 3?) Rented Megane RS for 2 weeks and did 6000kms in it (up and down QLD, and via every side road/mountain range available). Seriously fun little thing, left RS mode on the entire time and gave me an appreciation for magic FWD diffs (!) and electric throttles.. the fact that it gets ahead of you and opens throttle faster than you can put your foot to the ground is super fun. I can see why people buy it and its competitors and why they are so popular now (hot hatches). They give you enough of everything and are extremely good value for money. No normal person needs more car than say a Megane RS/Golf R and just super capable everywhere, and livable. I also have a soft spot for Renault's colors and stripes and stuff, some cool French design really grows on you there. Had a long chat with the guy with the Clio F1 182 at Broadford, these can be had for really stupid cheap for what you get.

Track day tomorrow, 97% sure engine will explode. Posting so I can tell myself I told me so.

There's a lot of mental processing reserved for exploding cars that don't drive right and being a complete noob driver you know! Finally got a friend's old beamer going and he also signed up for SAU. This is the guy that was fixing my car at Sandown while I was blabbing to Birds. His rationale for joining SAU was "Well unlike the BMW club they are at the track, and also I've fixed enough Skylines to be an honorary member even if they don't know it yet"

good isn't the word I'd personally use

As above, I had a GT with a custom exhaust on it, and put it right onto the GTT, no issues. So I'd also feel safe to assume the hangar locations are the same.

".....For the man who has two families, and prefers Bilstein over Eibach, and RB28 over RB25, and Coke over LA Ice, there is a premium option for you available, enquire within" Who am I kidding, this person does not exist

Watching for... More ultimate reasons.....

I miss German drivers. German drivers on the Monash could easily have it be an Autobahn.

Harris's info is making me wonder about my 7670 sitting in a box to go on my 2.8 (neo with VCT). But it's great info regardless! Glad to read it's performing as expected

To be honest, the amount of recommendations for 'good' places here have cost me more than the legal fees would have, in my personal experience, which is going to legal action against some of these stellar, amazing places which have no reported flaws. The amount of BS is nightmarish for some of these shops. I can understand in theory why they shouldn't be named but the community would be absolutely better off if the rule was actually do not recommend OR slander any workshop here, a strong focus as to Caveat Emptor as it is for private parts. Though oddly enough, there IS a bad traders list for forum users. When you only allow positive feedback you end up with workshops that do 8 things wrong and 2 things good trending positively, and over time, this just results in pain especially if these recommendations are old.

The SAU policy of not having any negative criticism towards workshops and only positive stuff does result in some very shoddy stuff happening at many workshops that are 'recommended' because of the confirmation bias. This is a legitimate issue if you use this site for research about where to go.

The severity of the things is entirely different. The difference is really how much concern there is for others, innocent bystanders. Doing 100 around a corner that has an "advised" speed of 50 in a 100 zone is very different to doing 250kmh infront of a school when people are picking up their kids. People in the video literally give no fks and do not concern themselves with hitting innocent bystanders. This is an important distinction here. Most people on the forum otherwise, when not being asked directly by police typically would think along the lines of "If I am the only person put at risk then this is OK". This video is not the same, nor anywhere close to that.
