i didn't want to be the first one to say something....but yea. wtf is this post really about? i think it belongs in the enthusiast forum. sounds like exclamation of joy over some installed mods.

Hot02SS

I think he's just commenting that he removed the O2 sensors, EGR, and A.I.R. from his Z without tuning, and he was shocked that the SES light only came on the first time he started the car, but not after that. Also, he had some difficulty with the knock sensor wiring clips hitting the bottom of his LS6 intake and with the #8 spark plug...but then again, haven't we all had fun with that plug!

i dont know how it is runing without throwing any codes.. it should be if you havent tuned it...
to tune a car in open loop like yours is, would be the high and low octain table, open loop a/f table, the ve table, and maf.

So I have to install an O2 sensor with auto meter gauge and drive the car to se if it rich or lean?

Hi guys, this is my friend's car. All Persian Gulf Spec cars have no O2 sensors on the exhaust manifolds.

so there all run in open loop?

RUF SS

I think so! is there any other possible way for these cars to run (with no O2's)?!?! As far as I know, there isnt. But I could be wrong. I have never worked with these Gulf Spec PCM before. But I guess there will always be the first time.

NOS4EVER

Any body nows how to tune this car (open loop)?

and what to use
