Title: e85 conversion on 2.7T tomorow some question Post by: A6turbofrance on August 01, 2012, 08:01:23 AM Hi
i have actually a stage 2+ ecu mapped for 93 octane and stock injectors. i just receive my 440cc @ 3 bar injectors for my S4. I have planned to fit it tomorrow with a fuel tank of E85 fuel for tune it . Does the ecu will adapt to the bigger injectors if the O2 sensor has been desactived ? Do i need to remap manually with tunerpro all my fuel trim for add 30% to 35% of more fuelling or the difference of the injectors size will do it . My standard fuel map is soon of 100% duty cycle of the stock injectors at WOT. My basic idea is to use lemmiwinks for add more timing ( i was thinking about 6 to 9° ) and only add cold start fuelling with lemmiwinks. I need to know if the ecu will not modify my fuel trimming if i put the 440cc one ... thanks for help.
