what's up guys need some input on this have a coupe with b16 in there didn't get the rear o2 sensor wire with the swap been running it with one o2 in there for a while now runs good got it dyno and all but my concern is some people are telling me that the other o2 sensor in there will make it run better i got a high-flow cat for it the light is on now but i took the bulb out. will the other o2 effect the performance of the motor or should i just run it with an 0bd1 ecu, and change it?

 

i was thinking of changing over to obd1 anyway should i just do that and run the one o2 sensor what do you guys think...............
