You need to make the files public.

A single 3rd or 4th gear pull from a little over 2000 RPM (not higher than 2500) to redline is better than a multiple gear pull like what you posted.

Just the one spot of FBKC towards the end of the second log, but it is not consistent because it was not in the first log at the same RPM / load / timing combination.

What are your AF Learning A, B, C, and D values?

Ill post up my third gear pull with af learning a,b,c, and d values tonight. Should I be worried about the fbkc in log 2?

Also. For some reason I get -1.4 fbkc in the mornings when I'm still warming up the car. Low load and no boost?!?! It happens with in my first 15 min of driving.

Turbo_powered · 03-25-2013, 07:56 PM

here is a log of a third gear pull

[edit] here is the right one.

I think you may have posted a link to the wrong log. There is no pull in that one, looks more like a short cruise.

jebjkey · 03-26-2013, 12:49 AM

Your AF Learning A, C, and D values are significantly off. They are almost at the limit of 15%. Your car is removing a lot of fuel, so a leak is not your problem. The intake is probably the cause.

Do you still have the stock intake? I would put it back on, reset the ECU, and drive for about a tank of gas. Then look at the AF Learning A, B, C, and D values again. I will bet the values will be good with the stock intake.

It does not seem like you have a WB, but I would suspect that you are running lean. AF Learning D also applies to open loop fueling. It does not look like you have any knock events in this log and your DAM is 1 so there is not a history of significant knock either. It is always a good idea to have a WB to keep an eye on fueling, especially on 08+ STI's with an aftermarket intake. I highly recommend you install one in your car.

What should my af learning a,c,and d be?

endrswrd · 03-26-2013, 09:03 AM

They should be +/- 5% and the D area should be as close to 0. Like jeb mentioned if you have the stock intake, I would throw that back on and flash the normal cobb 91 map as it doesnt look like your MAF scaling is proper for the intake. The crazy thing is all your other numbers look alright, which is surprising considering your Fuel trims.

I know that cobb also will say that things can swing to +/- 8% on GR chassis WRX/STi's, but from all of my experience tuning GRs, I havent seen this. But then again, I have all the GRs I tune do the fuel line mod / tweak the Load Compensation tables to fix the fueling resonance issue, so that may be why I dont see the 8%. hell I usually dont see over +/- 3-4%.

jebjkey · 03-26-2013, 09:13 AM

AF Learning values should be + / - 8% for 08+ WRX/STI (+ / - 5% for 02-07 WRX/STi).

Also, I meant to say vacuum leak in the previous post vice leak.

Turbo_powered · 04-01-2013, 07:50 PM

I now have my stock intake back in the car. Driving about 5 miles. The af learning looks like it is good. my a table is any where from 0 to -2.3, and b,c,d are all at 0%. this is on the cobb 93oct map.
Thanks for the help guys..
