the car is a ls1 406 with a gt55-91. the car is running on e98. I feel like the fuel is up to snuff. mgf efi 750 pump, -12 feed, 160 lb injectors. I have the car where it drives like a champ. Im trying to start tuning the boost and im having some problems. I have been trying to find some tuning info for this fuel. AFR etc. I have the timing at 15 deg. a -7 ngk plug(.021). converting the lambda numbers i have found for the ethanol and trying to tune it with those just dont seem to work. what i found is .71 rich and .87 lean. right now its at .74 (10.9 gas)(6.73 ethanol) the car starts to come into boost. around 5-10 lbs then just falls on its face. the logs are staying with in the comanded afr numbers. I just cant see anything going on in the log to tell whats going on. so far the highest inj pulse is about 40%. If anyone has any info they are willing to share please and im all open ears. thanks brian.
