Anyone do any J2534 Programming?

[mdoerner1]

Not talking about a cheap hand held tuner, I'm talking about the "VXDIAG GM" module (which is like a Bosch VCI)...and using GM's software on a PC to flash (or re-flash) a module....using Tech2Win or GDS2.

Now maybe VXDIAG is cheap, but if it has full J2534 functionalty, why spend $1500+ on a Bosch VCI.

I'll post a link again so long as the moderator doesn't delete it. Otherwise Google "VXDIAG GM".

I guess what I'm trying to say is that this sounds like a lot of hoops to jump through just to load a stock file to an ECM considering a dealer or an aftermarket shop can do this so simply. Once the tuning is updated (if there are even updates available) you'll not need it again as GM is not in the habit of updating software for vehicles much past the first year or two of service.
