Newest UTEC Revision - Nis01 - 09-28-2005
Was reading about the newest UTEC revision and it looks like they may have found a fix for your wastegate problem [Lee]:
The changes to the software include the following;
1. Addition of a launch RPM and a flat shift RPM setting.
2. Removal of start up CEL sequence.
3. Knock light (CEL) flash threshold is now user defined.
4. Active knock retard of maps.
5. Removal of coolant set point correction of fuel and timing.
6. Addition of air temperature correction tables.
7. MAF scaling for non closed loop fuelling.
8. Optional use of Boost Map 5 for PWM control of spare solenoid.
9. Transition smoothing of closed to open and open to closed loop.
10. Hold the wastegate shut until a predetermined manifold pressure.
11. Last event record of knock stored.
10. Hold the wastegate shut until a predetermined manifold pressure.
I'm not sure if this was available before, but it sounds like its a brand new feature.

Nice, how new is the newest revision? I think I got that revision when I got my car tuned... at the time it was experimental.
Wastegate flutter is cured now anyhow, the wastegate helper spring fixed it 8) Maybe I should check and see if I do have the newest revision though.
