I'm having a problem between 2-3k rpm since I installed larger injectors. I've tried leaning it out but it still backfires before I hit boost. The plugs dont seem to last as long as before I upgraded injectors. It drives great at all other rpms but I cannot CRUISE normally. I have to drive it in a lower gear and be above 3k. I'm running stock ignition w/ megasquirt v3.0 controlling the 780cc injectors. I've been tuning manually in megatune. Not quite sure how to use VE analysis in MegaLogViewer.

Can anyone that knows what they're doing take a look? This is the last log and msq file.

I wouldn't run RPM-based accel unless your stuff it pinpoint tuned, or only track-driven. Also in your Fuel Table Selection, you have both GammaE's turned off... this means it won't compensate for any changes (CLT, MAT, Accel, etc) - may wanna try those on. Reason I'm targeting accel is you log shows a lean spike whenever you even slightly change manifold pressure. You're also running really lean in your high end boost - give that VE analyzer a try. It's really something! Otherwise you logs don't really show a miss - maybe you have some other mechanical issues?

Cool. I'll try those changes. What exactly will the GammaE do when its on? Do I need to change an other settings for this to work right?

GammaE just takes into account those inputs like MAT, CLT, EGO(I think) to compensate your injector output. without it on it just goes by your table. You also have accel time as 0.0 ms, try something like 2.5 or so on decay. I could shoot you my .msq if you'd like, car's been runnin pretty well for me

The car runs like a champ now. Thanks for the help. I changed some settings and fixed the super420a ecu.

We really need to setup a msq database.
