just getting started tuning and tried setting the injector scale to 525 as recommended for the delphi 550cc and have the latencies set per recommendation of chris @ rvenge Performance but car is running 20 afr and o2s will not cycle. only way i got them to cycle was to lower the injector scaling to 420. then the o2 started to cycle and fuel trims are all around 6% front and rear. Wondering if this is the right approach to start or should i leave them at the 525 and start messing with the ve smoothing tables
