E85 on base oft map with cai. - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Flat Black VW · 09-06-2014, 10:19 PM

So I have an intake on my car. I just got an OFT tune and flashed my car to the stage 2 uel tune. My ltft were around 13%. I did some maf scaling and got those numbers down a bunch, still working on it but things are looking good.

My question is will it be safe for me to run the stage 2 uel e85 tune without any maf scaling? I assume it will be fine but just want to make sure.

Tia.

Once you get your maf scaling sorted on petrol you can transfer the scaling to the E85 tune.
but then log it and make sure AFR and long term fuel trims look reasonable ie less than 10% and that the AFR is following the values in the OL FUEL Tables for the E85 tune

I ran the S2 E85 tune with my Perrin CAI and had no issues on the stock tune. I ran it for about 5k miles and switched back to 93 recently for the winter.

Edit: Just to clarify, you have an UEL header, yes?
