Hello,

I disabled on a few LS3 and LS7 the rear O2 Sensors After installier Headers and everything is ok.
Now i made the same on an 2005 Ls2 Corvette and After a few minutes i had in the Cluster the Code repair Electric System. Going back to the Stock Data of the ECU it is all ok.
So it has to be something with my New Data .
Does someone had this Problem also and how you fixed it?
Can someone who has the same combo, Long Headers and other air intakte and no Engine light on send me his tune?

Kind Regards

Markus
