Sorry guys - I know there's plenty of threads on this subject, and did some reading, but still not sure what to do.
As I mention in any thread I start - I am not very mechanically inclined, so bear with me.
Made some changes to the car recently, and now I'm having knock issues according to my scanmaster, although I didn't hear anything. My mods are in my sig. And I run 93 octane. That's all.
Converted to vacuum brakes. All is good with that. Don't see how that could tie into my retard anyway.
Only other two changes I made were an adjustable wastegate and new fuel pressure regulatory. I did have a few rusty fuel lines changed as well.
All this work was done with the help of my daily mechanic.
We set the FPR at 43# off vac. Connected, it was right at 38/39. Adjusted wastegate, took her for a spin, and no problems. At WOT, I'm right at 16# of boost. Made several runs, and no codes or messages or knock retard. My mechanic kept an eye on the scanmaster while I looked at the boost gauge (I did not want to overboost). This was 2 days ago.
Today I'm out taking a run. Roll into WOT from about 40mph, it downshifts, accelerates, and I see the retard # pop up so I back off. Pull over and check the recall: 10.1 degrees at 52mph. 789 millivolts. I ain't no mechanic, but I know that 10.1 is NOT good.
Prior to these changes, there was never any retard on it. None. Zero. And if it matters, I was only pushing 11# of boost (which is why I changed the wastegate).
I also had a fuel pressure gauge installed in the engine compartment. When I looked at that today - and I'll admit its not a top of the line gauge - it appears to only be reading about 29-30# at idle with vac on and engine warm. The other day, it was definitely reading right around 38/39 with the engine warm.
All my other scanmaster readings seem to be within spec.
Thoughts? Is it something with my new FPR? I only changed it because I figured "why not", the original one was still on there. Or, has having a new FPR with correct delivery now uncovered a new problem that wasn't visible under the previous one?
Appreciate your help.
