Since datalogging has been enabled I now have the tablet mounted. Was wondering if there is anyway to have it turn off with the car and turn on with the car? The way I mounted mine is very tedious the have to unplug it every time to shut it off.

E85 knocks on the rich side, but in my brief experience with it is incredibly forgiving of afr. You'll want to target like 12:5-12.8:1 for NA on e85, depending on who you ask.

You adjust the fuel targets in the fuel map. You may want to check and see how far off target you are and why, though. I doubt it's targeting mid 11's. It's very likely that your injector scaler and di flow rate are not properly calibrated for the blend you currently have in the tank (which it won't be if it's your first tank in top of pump gas).

Thank you. My concern is only premium pump gas - we don't have E85 here.
Which fuel maps did you mean should i adjust to target AFR 12.5?
There are several fuels maps available - which one is affecting AFR rate on WOT?

Youre on pump gas? The afr is adjusted using the fuel map, though you shouldn't have to adjust it. You wanna knowing you're off target and if so, why.

Exactly want to know why!

But still cannot imagine what could be wrong.
MAF scaling? MAF sensor itself?
OFT doesnot see any errors in ECU...

gather data. log stft, ltft, maf v, iat. collect at least 30k rows (probably a half hour drive), and then pm me.

How much max timing advance do you typically see on a stock car on pump gas?

As for my log - it shows widely from 10 to 40, while it is 26 - 28 on WOT pull.

I currently have Motiv Catless front pipe and Nameless 2.5 axleback and stage 1 OFT
I just tried my 1st 3rd gear pull and it seems like AFR is a bit rich??

Unfortunately, I can't tell from that link. It would be better if you just post up your log at datazap.met.

Can't say I've ever seen LTFTs that high. Tune is perfectly safe but running rich. Try this: Load up your stock ROM and drive it for a day or two. And then take another datalog so we can see where fuel trims settle. What other modifications do you have?

Also, could you email me (shiv@vishnutuning.com) a copy of the ROM that you are currently running? I'd like to see something.
