Where did u relocate to? I have the air /fuel. Sensor post turbo and the OEM post Cat...View attachment 143273View attachment 143274
I just had to relocate my sensors.
Post turbo was not a good location.
The second picture shows them post manifold. I found that the heat didn't get high enough post turbo, and if the turbo leaks oil at all, it messes up the sensors.Where did u relocate to? I have the air /fuel. Sensor post turbo and the OEM post Cat...
I should have clearified I put the 2 that were at the manifold where you put yours. I put the 2 that were post cat from factory post cat again. The air fuel mix sensor went post turbo 10-12” from Turbo downpipe as the instructions required. You should not have three in that location. You won’t get the correct readings...The second picture shows them post manifold. I found that the heat didn't get high enough post turbo, and if the turbo leaks oil at all, it messes up the sensors.
I’ll see how to download and send the file...Interesting, I hope it works... and I would be interested in an HPTUNERS scan of the program once its installed.
Excellent thanks!View attachment 143281
This injector data is extremely important to tuning. I hope your tuner has this data.. it's the ground floor to tuning bigger injectors.
Plus ford and GM use 43psi (3bar) fuel pumps and Jeep uses 58 (4bar) which push more fuel through the injector.
When you say air fuel mix sensor, do you mean the Wideband?I should have clearified I put the 2 that were at the manifold where you put yours.

YesWhen you say air fuel mix sensor, do you mean the Wideband?
I can still move sensors around because I have plugs inserted in the bungs.
My 2002 has two sensors precat and two post cat. This is also the way Banks does it to stay smog compliant. Then there is the added wide band inserted 10-12” from turbo in downpipe. So there should only be two at your exhaust manifold before cat. . The two post cat can be tuned out if you don’t care about smog. I was told to place them post cat even though my cat is far downstream from my turbo . The computer needs to get a reading and the reading from those two sensors needs to be clean. So that far downstream after Cat should be enough to satisfy the computer. My Cats were in perfect condition when I relocated one of them after turbo in downpipe... Those were the instructions given to me. I will post up the results as soon as I get all the components back together. It won’t be in the next couple of days there is a lot to do still.I can still move sensors around because I have plugs inserted in the bungs.
At the moment I'm tuning with a tuners, and both o2 sensors are off to force open loop. So I have the WB close to the engine.
I also had an issue with the second bank o2 contradicting the first, so im not sure if the second o2 will ever be used. At stock each sensor reads 3 cylinders, but now each sensor is reading all cylinders.
Why do you think that 3 in that spot won't work?
