It looks like you have had auto tune correcting under over-run conditions. You need to be steady state when using auto-tune. 5 hours ago, efi265 said: also im trying to do cold start with e100 .not really a happening thing. This is why "flex fuel" was invented. You need fuel vapour for combustion, ethanol has a very low vapour pressure so produces very little vapour in a cold port. The idea of flex fuel is you reduce the ethanol content in the winter so there is some more volatile petrol in the mix to produce some vapour.
