Nolift to Shift??
quick update - testing is finaly going well - we had some problems with my code for a while 
Eric *might* post up some screenies of logs if he has time - but apparently it works pretty well.
Yes you still get the KnockCEL + you also get my valet revlimiter.
Cheers

First of all, BIG thanks goes to tephra for working so hard and making this happen. Great job!!!
A couple of notes... For testing purposes, I was shifting at about 6k RPM and I wasn't banging the gears...it was about .4-.5 seconds per shift. Also, I was at low boost of about 18 psi or so for testing. (Anyone who has Logworks and wants the actual log, let me know.)
Even so, the screenshots show that the throttle was 100% for the shifts. The TPS is the line at the top obviously. I know the screenshots may be a bit hard to read since I had to resize them small enough to post. But, you get the basic idea...the throttle is held to the floor during the shifts and the RPM doesn't hit the roof. It drops because of the NLTS rev limit.
The first screenshot is a 2-3 NLTS and the second is a 3-4 NLTS. The boost drops to about 8 psi during the time it took me to shift and recovers very quickly from there. So far so good.
(I know this is a bit off topic, but this 2-3 log above shows some bad throttle hang, known to be an issue on the 05s. At the end of the screenshot, I am in neutral with my foot entirely off the gas, but my RPMs (light blue line) held at 5k until I touched the clutch.)
Another note... When I was testing this a bit, I noticed that perhaps the stock flywheel on the Evo may not allow the engine to rev down quick enough, meaning that you can probably shift faster than the engine is going to reach the NLTS rev limit. If so, you still get the benefits of having an open throttle plate and keeping most of your boost. I think people with lightweight flywheels will benefit from this even more.
