I went ahead and on my GEN 2 prepared it for a ECU flash i am getting done. it already has a FULL SYSTEM Yosh R-77 4-2-1 system with a PCV and AUTO TUNE (but dont think it had the dual band o2) and quickshifter all by DYNOJET.. i was not happy with the auto tune, still had some after fire issues and wanted to at least disable in the ECU flash for the smog pump. so i took pics while doing this and hope it helps you do this fairly simple modification. so... here we go!! lol
