Utec keeps retarding timing
Even on "0" the Utec thinks my car is knocking and keeps retarding the timing on my turbonetics G. Anyone know what's up with that? I take the Utec out and run reflash and the car runs fine on the Dyno. I even turned off the knock sensor and the Utec keeps wanting to retard timing.. Did I get ANOTHER bad unit?

are you talking about the 0% load column? Depending on what your parameters are, you might actually be knocking. I have found the utec knock feature to be pretty decent. Maybe you could paste a log for us to see... then we can try to pinpoint the problem.

Loose Exhaust?
What is your knock sensitivity set to?

downshift,
which engine have? I have a revup, TN and UTEC. I keep getting knock counts even with a Fat A:F and REALLY conservative timing. The stock ECU is picking up the knock....its timing isn't changing. It happens in the 4500-5500 range. Could that be the range where the ECU is shifting the cam timing? could the UTEC be picking up that noise?

If its not pullin timing, have the utec do it. My stock timing was knockin at +27 from 6000 rpm's to 7000.. Pulled stock timing -1 and that took care of it.. Try that it should work..

I have looked at both. in most cases, the stock ECU does nothing. But the UTEC is registering a knock count of "8." 
I have seen some occasions where the UTEC is not registering any knock, but the ECU is retarding timing by about 6 degrees. odd, huh?

I have a stock flywheel. I figured that they are quiter than the 1 piece aftermarket flywheels.
BTW, Thanks for all your responses. I definately appreciate it.

isn't there a way to shield the knock sensor wire to prevent interference from a flywheel? I intend to run a fidanza and don't want to come into issues with this!

The stock ECU will retard it's own timing, to an extent..We really need datalogs to help you out.

I was looking at the wrong column!
