I'm a little confused. The car dies if I crank it with the AC on on start, immediately. What should be adjusted for this? I'd like to have a 1300-1000rpm decay for hot-starts like this.
Also, I don't really understand PID idle control as well as I should. What would make the car idle fine for ~5 minutes. Then without even being in the car it will "chug" and attempt to idle at ~500rpm...then go back to normal after that 5 second event.

log the chug! it could be anything, but im thinking maybe a tpsdot event.

shouldn't have any issues running the a/c and cranking...possibly not enough fuel in that area on the fuel map during the decay?

Well, I had 7 sync-loss events in about 10-minutes of driving today. What needs to be done to make this stop? I believe this is causing my random idle problems.

I'd also like to solder-mod the VTPS on my MSpnp1 so I can sell that thing.

I'll come to you. I'd love to learn how to do this. My biggest concern is that I don't have a solder-suction tool, don't care to buy one, and don't care to learn on something expensive and critical.

IIRC, you're just doing thru-hole soldering, right? I think that's what I saw from Graeme's picture. Nothing surface mount.
A decent solder sucker isn't that expensive. $35 7881 Weller | Mouser is what I have.

Is there anyone runing VVTuner with a DIY built unit and do they have this problem?
Only you can decide what to do. I did not want to mod my box and remove designed functionality, but as it was, it did not function the way it should have. Go back and read my posts, both here and at msextra.com, I asked the same questions.
