O2 sensor question
Okay i am getting my tranny swap started now, and the guy is also gonna do my exhaust....while he was looking at my exhaust, he found that my O2 sensor wholes had been welded shut and said i would need to get new O2 sensors and get them in there....
Do i really need O2 sensors? the exhaust is LTs, o/r x, and flows...the new tranny will be a manual....let me know if i need them, No emissions to pass or anything like that. if you need any more info about the car, let me know that too. Thanks |

Re: O2 sensor question
one question...do you still have o2s hooked up at all, maybe hanging somewhere else? if they are, unhook them or they will read the obviously lean atmospheric a/f ratio and the ECM will constantly be richening the mix by lengthening the injector pulsewidth to the maximum. |

well this exhaust is on my parts car and whoever rigged this thing was dumb and i could have done a better job. i will have the guy doing the swap for me do some more searching on the car....How much are those wideband sensors you spoke of?

Re: O2 sensor question
Or....he could take it to a local dyno shop and get a tune that would cost alot less than buying a adj FPR and a wide band setup. FYI...tuning via fuel pressure is not the correct way to adjust for rich/lean issues.

Justin: by saying taking it to a dyno and tuning it do you also mean not getting any O2 sensors? I am getting a tune @ Speedy's of all places (LOL) in a few months, explain your reasoning further as i dont have tons of money...explain the cheapest route for me to take in anybody's opinion please

If you were planing on getting a tune anyways...then definatly dont spend the money on the wide band setup. As far as adjusting the A/F via an adj. regulator...if your needing to do that...then the problem is somewhere else and it needs to be address instead of putting a "band aid" on it.

Re: O2 sensor question
Especialy those cars with CAIs and altered exhaust. People put way too much faith into the abilitys of the stock ECU to adjust itself properly. This is more so with the 95 and earlier cars.

With the SCT software, you can remap the entire fuel and igniton curve throught out the entire rpm range at any throtle postion. Its not rocket science by any means...just need a "loading" chassis dyno and data logger. I have also seen and used the tweecerRT. Like any other tunning setup...it does work....but I was not impressed with it.

"We'll use your car's o2 sensors, just where they thread into the longtube headers on the parts car we'll have to put new mounting bungs."
That is the exact words that the guy told me that we can do. Does anybody see a problem with that or am I good to go? Thanks
