My headers and valve train are triggering the Knock retard...

So I tried to register on the Corvette forum so I could add info to your post about the T100

The captcha did not show up so I could not register,

I...

So my thought process shifted a bit
If I cannot find the voltage shift online I can always test for it In VIVO
I will change this circuit as I think about it more and post it here.
If I can not...

Back to my original question
I know that O2 varies during the test but the change threshold for the EGR test is the manifold Vacuum.
The question still is does anyone know the threshold values that...

I played with trying all sorts of diagnostics on the EGR when I first replaced the broken manifolds thinking that the EGR wasn't working it was but occasionally set code 32 anyway the silly part is...

Thanks Dave W
Thats the runtime variable isn't it ?
I am looking for the MAP change window for code 32 during the test.
I have used tuner pro and Cats bought full versions of both.
I have not...

I currently have a project underway should be finished in two weeks.
I have a 1995 GMT400 SBC 5.7 TBI A couple of years ago I put a set of try-Y headers on the truck and began occasionally getting...
