Most of that was playing around trying to learn the system and looking at other things. The ECM recode itself took almost no time or effort.
So far we have mavicman that still needs coding checked and corrected. Anyone else? Who has VCDS near Snowmass Village CO?
Moving forward, anyone that is planning on sending in a spare ECM needs to talk to Speed Tuning about checking the coding and making sure it is set up correctly for your specific car car. There are only like 4 variables that need to be set, but they do need to be set correctly.
I've been away from the forums for some weeks traveling and what not. I have had a coding mis-match CEL and the ESP light on the dash since I installed the tuned ECU. I have vcds and followed the procedure on Ross-Tech's wiki for re-coding, but the coding would not change.

Steve, what process did you use to recode TheWay's box? My spare is a matching part number to the stock box, but the chassis digit in vcds is one off from what it should be. It's been a couple of weeks since I looked at it, and the laptop battery is dead, so I'll charge it up and re-read the car tomorrow to see what's what.
As an aside, around the time I installed the tuned ECU I had to replace all the PCV stuff, valve-cover gaskets/cam chain tensioner gasket, and the entire ignition system. These issues were totally unrelated to the tune, just kept the car off the road for a while as I tried to fit the work into my schedule. Since I got the car back into action, the throttle seems somewhat smoother, and it pulls just a little harder (perhaps), but no dramatic change on the V6 performance. The changes could have been from installing a properly functioning ignition system. Maybe it'll improve some more once the ECU coding is sorted out.
