ecu and o2 sensor question

[erebunicrx]

i swapped a ls into my 91 crx si. i used the stock ecu. but schould i get the 91 teg ecu? how much power am i losing? also when driveing for a while the cel comes on and says the o2 sensor is bad then i shut the car off for a second and the light goes off and car runs fine after.

either chip your stock ECU or use the teg ECU. nothing else to be said.

ok so am i losing power with the stock ecu? or am i losing just the higher rev limiter. thanks

the fuel maps are all wrong.
get the teg ecu.

it may solve your o2 problem as well- due to it giving it the wrong fuel and making it run improperly
