2002 drive by wire tune

[s10mods]

Does anybody have a 2002 truck that has Drive By Wire throttle? I'm looking for a .tun with a 12212156 OS and a 12200411 PCM service #, most important is the PCM service number, I am willing to change os#'S let me know if you have anything

The 2002 Vette (LS1) has the same OS,

(12212156) and it seems to have all the ETC parameters in there. Which means it would probably have a better ETC set-up than a truck tune. As a suggestion you might try that.

I would try it, but his will be in a 4x4 truck and I dont think the vette will support the pcm shift table for 4 low. I had some trouble with this when I helpped a friend put an ls1 in his Yukon. I still dont think it shifts right in 4 low.

Isn't there a 2002 Express Van .tun on holdencrazy that would work 5.7L L31 ?

I need the file for the LQ4, or at least a Gen III so I have a base to start with.

The only tunes for the DBW for a 411 PCM were in the 2002 Denali and Escalade AWD as I recall. While I usually have total recall I don't always have same day service. The DBW for 03+ were the 1mg PCM. Find one for the 4WD might give you a starting point.
