Evening ladies and Gents.

I have finally stepped over to the darkside after 15k on my 2014 Evo 10 GSR. I installed the accesport and loaded the stage 1 93 octane tune. After about 350 miles my LTFT's are super high IMO. Below i will attach two logs (and pic of the whip); one with a pull, one at cruise. If you wouldnt mind giving me some advice, tips, or opinions I would greatly appreciate it.

 

Anybody? All i am looking for is some technical advice.

 

technically, don't post pdfs. nobodies gonna bother to convert it back to csv

 

So how does one attach a csv when it will not upload? Oh, didnt realize computers now-a-days could not open and view PDFs

 

zip it foo

 

Thanks

 

Your boost and timing is in the safe range. You're prob. flowing about 6-10% more air (at least in cruise) than the MAF table is currently set. Even so, your fuelling is prob OK at these levels, but depending on level of OCD might be worth touching up in cruise and then in boost. What mods have you made outside of the reflash?

So if you want to, rerun pulls covering RPM range from 2K-7K. Do it in 3rd gear (or 4th, safe conditions permitting). Flat road is better, but uphill is fine. Throttle should hold stablized RPM upon entering pull, then go instantly to WOT and held till end of pull.4th gear pulls let you collect more samples. Another way to increase number of relevant samples is by disabling logging some PIDs, in this case STFT, Fine WGDC, WGDC corr. You do want to add logging map calc and maf calc.

 

Thanks for the info, really appreciated.

I only have a cobb cat back, which doesnt really have an affect on anything. Ill try to log again as you advised, and add/ subtract logging tables.

And yes, the OCD doesnt help me any.

 

I have new Logs with updated PIDs.

Most logs regarding MAF/ Map Cals dont seem that far off.

What do you think? Anything to be concerned about?

Thanks

 

MAF is lower than MAP by up to 10% up top, but even so you're safe based on merits and mildness of the rest of the tune.

I'm not saying point is to *just* make one calc equal to another, but to scale them to equally *and* accurately represent actual airflow. From this you have the foundation to sanely approach tuning fuel, tuning timing, etc.

 

Thanks man I appreciate it. Ill look into scaling, hopefully accesstuner race will allow me to do what I want.

 

Great instructions
