the logs show nothing, but now at 6800-7200rpm it pops and the knocksense light goes off. I hear no detonation, the log looks fine, and AFR is perfect 11.5:1.

Its colder tonight but the intake temp look reasonble at like 5* over ambient. Any thoughts?

 

plugs are gapped to .040 with cops. It did this on the stock ignition at .020 until I tuned it, then it magically went away.

tomorrow I'll get the det-cans back out and jack with it further, but for some reason unburnt fuel is making its way into the exhaust.

 

.040 might be a lil big even with COPs. I think I still run then but that's my guess. Maybe your plugs need replacing.

 

post up a log file anyway.




maybe it's the oil pump gears?

 

try a little less gap

 

I'll drop em down 010 and make a log for you gays.

 

I just remembered that i switched vacume sources fr the computer. Now I have the smallest vac hose i could buy, on the 1/2" brake hose line from the BEGi kit. I did this to hopefully smooth out the signal...any thoughts before I go out there and waste hours on end?

 

considering my targt pressure is 200kpa, should I adjust the kpa axis to hit that target due to the massive change in values from 184-212?

This is why we don't change anything after we spend time at the dyno.

 

How small? I've seen people put restrictors in the line and it caused problems for the MS. The signal was very badly delayed. It would actually hold vacuum between the restrictor and the MS after the car was shut down.

 

well, after reviewing and comparing logs, it was better before with the fuel filter and larger line. I'm going to switch it back now, at a supercharger shop, lol. Its not popping today, and driving like normal. I'd like to have some input on the KPA values though. I hate to adjust this **** away from the dyno.

 

you want to change the values in the table axis? dont bother. it's interpolated and probably 100% fine.
