So I attempted to lean out the STG 2 EL E85 1.55b tune for my bone stock FR-S by adjusting the Fuel Map and Closed Loop AFR A and B. After loading the leaned out tune I did a couple of pulls, and the AFR is just as rich as before. What gives? Where else do I need to modify? I just want to lean it out a little bit across the board.
Here what it looks like against the stg1 tune on Virtual Dyno for reference. Seeing that the stock O2 reads lean at the lower AFR's this is really rich for a E85 tune.
