yes once maf scaling done and some load limit tweaks you should get mid to low 12 afr on e85 , ie its folowing whats in the open loop fuel table

Do I understand correctly that maf scaling shouldn't be done on E85 but on gas instead?

you can do it on E85 you just need a stable source of e85 while your scaling maf as if you e% keeps changing you will chase your tail trying to scale maf.

you could probably take the e85 maf scaling out of wayno,s tunes that he has posted up would be a good starting point.

as your e% changes the fuel trims will move up or down but should all go in same direction.

what you dont want is +10 ltft in some areas and -10 in others , your looking for consistency in values accross the rpm range.

Alright guys so I have been running the OFT Stg 2 EL E85 map for almost 500 miles now. Car is stock other than K&N drop in filter and Greddy Evo GT exhaust. I have been meaning to post some data logs and get some insight as to how everything is running. I am very new to all this and I only know as much as I have read on this forum. Any help is much appreciated!

First link contains two, WOT, 3rd gear pulls and also a cruising log. I set the parameters to check for knock (please correct me if I left any key ones out)

Second link also contains two, WOT, 3rd gear pulls + a cruising log. This time I set the parameters to monitor AFR

I'll let steve99 answer, but from what little i know it looks decent (albeit a tad lean at redline).

@steve99 - here is the updated post (end of 2nd tank). i deleted a CEL (U0073 i think) and then started recording for the drive home. afr looks the same (i.e. mid/low 11s) while the command afr looks good (mid/low 12s). i tried doing higher gear pulls (4th and 5th), so couldn't get all the way to redline at times lol

Hey guys just tuned my car using OFT stage 2 EL E85. I have no clue on how to read the data log since idk what half of the things mean. All i know is My AFR is a bit lower than 12. I don't know if that's bad for the car or not. can someone please take a look at my data logs and let me know if everything is running the way it is suppose to be (LTFT and STFT). Would greatly appreciate it.

10 to 12 whole points isn't a tad.

Does this mean I should start some MAF scaling?

Nope haven't touched any of that yet should I start ? Or should I lean it out a bit ?

I would get the MAF scaling right before touching anything else.
