Lot's of a/m parts. Got it for a song because the last owner decided to buy a completed project. Big turbo, intake, exhaust, fuel pump, injectors, etc etc etc.
I know the ECU has been tweaked. What I don't get is why, when I pushed it this morning, it bounced the RPM's when it got around 6,200 RPM's. The thing runs and idle's perfect and even smogged at DEQ yesterday with flying colors. Now I'm not familiar enough with GVR4's to know what happens when there's engine knock. I do know the last owner told me that he could never run more then 13PSI because it would cause knock.
It felt like a rev limiter. No check engine or warning lights and no odd sounds (aside from the engine RPM's bouncing off of whatever it was). Same in 1st, 2nd, 3rd. Stopped pushing at that point.
I'm ready to buy an ETS intercooler and DSMLink. I was going to put it off, make it a reward for passing a certification exam, but if this is knock, I'll pull the trigger on it now.
Of course, if this behavior is NOT what the knock sensor would do in the cases of severe knock (where it can't just retard the timing a bit), then my guess is the last guy had the tuner set the rev limiter lower then the redline for some reason and I'll get this bitch out to English Racing and get it sorted out.
Thanks in advance, guys!
