Vortech tuner kit + Utec + cool weather = lean a/f
Hello all,
I have a vortech tuner kit with CJM stage 1 RFS, RC440 and walbro fuel pump with a utec for EMS. Utec was tuned by MRC over the summer on a very hot and humid day. Since the weather is getting cooler, my car is giving me a CEL (P1273) for A/F sensor lean shift detected. To fix this problem, i can either increase fuel or retard timing or both. How do i increase fuel/retard timing on the utec??
