Hi
I Have had my car working perfectly with 98 octane gas for a while now. I finally installed bigger injectors and started to tune it for E85. I first made it work with 98, and it only needed minor adjustments. I have continental flex fuel sensor and want to use table blend so I can use 98 in winter and if I can’t get E85. Am I doing it the correct way if my VE on table 2 needs to be a lot higher than on table 1? Its roughly 35% higher VE. I tought that the VE would stay more or less the same and the ECU would account for the difference in ethanol content.
I also had a problem with the autotune. It has worked very well before, but now with E85 it tries to make the car run really lean. I adjusted the VE to show spot on 1.00 lambda at cruising speeds, but when I try to use autotune on the log, it wants to subtract 10-20% from everywhere on the cruising area. This makes the car run at 1.2-1.5 lambda which is obiviously not good.
Any help will be appreciated!
