2006 Chevrolet 2500HD , Compustar 2W900FMR, (CM3000), Fortin GM SL2i...

Program Fortin and RS works perfectly for a few starts, then LED on Fortin glows steady and RS starts and dies in 1-2 seconds. Re-program Fortin and RS starts fine again for a few times. Any thoughts?

Also does anyone know why Fortin has addendum for GM SL2i V. 1.0-1.8 to add 1k resistor at OBD (purple lead) to ground?

My favorite customer questions of all time... "Hey man, how many watts do them speakers throw"? and "Yeah, but what's my price"?

It may have something to do with the bypass's DATA signal not being stable, on those particular vehicles' BCM input.

Could that possibly be your problem? Are you using D2D or W2W?

Ideal - cmon dude, add to topics in a useful manner, not stuff that is obvious.

Story - Phzzzt! Hey, what happened?! ... Isn't it obvious?

Moral - Never dismiss the obvious.

I am using W2W as Compustar CM3000 has no data inputs. DId some additional checking and a quick call to Fortin. Determined the Fortin unit would drop its programming while RS engine run after 5 minutes of run time without key being inserted. Any less run time would not result in progamming failure. According to Fortin tech, "just replace it with INT SL and everything will be fine", (had kind of an attitude)!
