I decided to run the 95 octane map out of curiosity and got no misfires but fueling looks like a concern. Got an appointment with dealer in am to address hpfp issue so hope that goes well. Mean while can someone check these 93 logs 😕 . plugs were changed 2k ago FBO minus fmic (on the way) http://datazap.me/u/d8rknight/93-and-95?log=0&data=4-22
Keep in mind I've been running Cobb e30 and st aggressive map the past year no issues  |
What codes are you getting? Misfire on the same cyl? Could be a bad coil or coils. This log looks much better and it doesn't appear your HPFP or LPFP is struggling at all.
Next time you log, you should go WOT for the entire gear if it is safe to do so. Ideally WOT 3rd and into 4th and hold it for 2s. |
Cyl 2 misfire 29CE. I can never go WOT cause I'll get a misfire. will pull plug and see if it follows plug, followed by coil
