Eliminate front o2 sensor (OBD-I issue)
I can't tune correct the a/f on idle, the WOT "area" work fine but the car run rich on idle & low rpm's. The ECU have "o2 sensor CODE", i tune in open loop and mid rpm's & WOT work good. I want eliminate the o2 sensor on the fuel map, "0 value" on the close loop area? Any info?

Take the 02 sensor out and tune it then. I put my Wide band O2 sensor in place of the stock 02 sensor about 3 years about and havent had one problem tuning since. The 02 sensor code shouldnt affect anything since you have the capability to tune. The computers on these cars arent that smart which is a good thing. You can make the Idle to redline not at WOT as rich or lean as you want by just adjusting from the computers stock maps. If that didnt answer your quesiton im not sure what your asking...


What is the problem your dealing with?

Not to jack thread , but would there make any difference in having the o2 sensor in a sinlgle exhuast stream,primary tube on header......than putting/rewiring the o2 sensor longer to the bung near the flexpipe, on ssac, so all the exhuast pases the sensor,......and using the 4 wire o2 sensor and doing the o2 sensor re- ground that vadim did some where??? I think it reground at the back of the intend manifold???
