ECM hardware + ECM OS + throttle body need to match. If they don't, it may or may not work, or issues could pop up randomly down the road.

I've got 09 Express Van ECM and TCM files, I can attach them if you need them. If you're looking for an actual "tuned" file, I'm not currently doing remote tuning but there are lots of good folks who can.

You also need a wideband O2 sensor wired up and connected to your V2.
