In the short future I will be purchasing a 3rd generation Maxima, J30 chassis. I was wondering if the OBD 1 system on the VE30De motor runs an O2 sensor after the catylist. If so, how can the ECU be fooled into thinking it's reading a correct O2 sensor map without the catylitic converter? Thanks for any suggestions.

 

adam, OBD 1 does not utilize a second o2 sensor, thats only OBD II and that wasnt implemented until a few years after your 92

 

Ask "Dxplicitone" Hes got a newer maxima (well his girl does)......Not sure do to the fact that I dont like FWD so I dont keep up..........Ask me anything about a RWD Nissan L-series up.....lol, why not just have a high flow cat? or retune the ECU instead of tricking it........

 

^What he said ^

 

im also in favor of high flow cat, cause i'm environmentally friendly...haha eventually that's what i'm doing when i go to 3" exhaust

 

Thanks everyone.
