Hey everyone,
I tuned my A3 1.8t (AUM 032FC) for running on e85.
Fuelwise, it has a 4bar fpr and scaled krkte and full load target lambda to match with e85. The fueling is perfect everywhere except for one thing that bother me on daily driving and fuel economy...
The fuel cut only appear when above 2.2k rpm and most of the time when it's downhill. (lambda stays at 1)
Ideally I'd like to cut the injection as soon as I lift the throttle and as long as I'm above for example 1400rpm. I think it would decrease my fuel consumption a lot doing that and get a better driveability since I have no engine brake below 2k rpm except in very low gears...
Any ideas on where to start ?
If you have any idea on how to tune for economy with e85 on partial throttle low loads, I'm interested for my daily driving and long trips. Not because e85 consumes more etc but to get the most out of it in every situations. Where I live it's more than half the price of gas and for the performance I get out of it there's no point running on crappy 95.
