Ok so most of this "tuning" subculture is very fascinating/confusing. Swapping my 89 small block for an 02 LS3 was simple enough. Getting around smog requirements in CA is always a challenge (but fun), unlocking my ECM simple thanks to HP Tuners. Asking forums community members for help, a necessary evil, so here it is.
attatched tune and log files. O2 B1S1 reporting .44? constantly while B!S! varies with conditions as it should. Ive replaced the sensor and inspected wiring with nothing found. Assuming all is good physically Im looking at the tune itself. Is there something I missed? enabling something I shouldnt have or not enabling something? Ill start there and see if I can understand any replies and suggestions offered by anyone. Ill try to do as Im told per any recommendations and see if that helps. Understanding theory of tuning ie MAF vs MAP Density, 2BAR 3BAR .............. Anyway if anyone can tell me what im doing wrong/why O2 b2S1 is stuck on that voltage please. Thanks in advance.cold start idle til warm 4.4.23.hplRoy Tune 4.4.23.hpt
