Do any of you find that you go through oxygen sensors faster with tuned ECU's than without, due to enriched mixtures under boost, more exhaust heat than stock, etc.?
I am getting recurring O2 sensor CEL (6 blinks) on '93 9000 Aero (only one O2 sensor) with staged software package - it never ran right with the stock software, and I am not attributing the code to the tuned software, just posing a general case question.
Best,
Drew
