I've done many modules off-board recently. ECMs, radios, FPCMs and all have programmed just fine with TIS and the MDI.
There is an MDI-2 coming down the pipe since GM just released the new software to support it.
2009 Maverick Silver G8 GXP M6 - 586hp
Engine Mods: TVS 2300 Magnacharger ARH 1 7/8" long tubes with catted x-pipe

Misc Mods: Jamesbiz Catch can - GRRRR8 Heater hose relo kit
very interested in what the people in the know say about this
I do it all the time. I have a homemade bench top harness that I made up, but I also run a BCM on it.
I can flash the ECU or BCM bench top with a J2534 pass thru and GM SPS.
It doesn't seem to make any difference what BCM I have hooked up it still will flash the ECU. But if you have a BCM or TCM on your bench top harness you have to have all of them plunged in or jumper out the Can high and low wires as they run thru each module.
if I am reading this right, the BCM allows it to pass the "off board programming detected"?
I wouldn't say that. I just so happen to need to program BCM's so I added it to my cable. Unless something has changed you should be able to program any GM ecu with a valid license to GM SPS and a off board programing J2534 Tool.
I did run into some errors when programing after trying to load the wrong calibration into a E38. I thought 12625455 ECU was for 2009-2010 and after putting a 2010 calibration in it, it bricked.
Here is what I found for E38's
2007 19210738
2008 12612384
2009 12625455

I think people using SPS won't have issues.

Just say no to bull s***.
IF YOU WANT HELP, POST A FILE!
well, I ordered my benchtop programming adapter from EFI Connection, and I use SPS, so we shall see
I will report back
Any Updates ?
sorry.. yes..
the problem I had MUST have been in my homemade adapter
once I plugged in the EFI Connection "pro" adapter it worked like butter!
Awesome !
Was just gonna say, I've never had issues with MDI and SPS either. More than 90% of the stuff I do is on the bench. Sometimes I don't have the engine harness or bench harness, so I end up just making something with pins and still don't have any issues.
the weird part for me was that HPT worked fine with my home-made adapter, but not GM stuff...
