2008 cobalt, alarm/remote start

Luckily its coming to me this time so I'll have full use of my resources. I'll try reflashing it with the GM2 firmware and go through the programming again. That plug looks exactly like the one in the car (from what I can remember)Kenny

no need to connect the start wire. Only vehicles with the start wire requires the connection. make sure you power acc and ign at the ignition switch and not the BCM @ dkp. reflash the idatalink module with the GM2 as kregs mentioned, that's the actual correct firmware for that vehicle. one other thing to note: make sure you correctly wire the passlock wire (car vs switch side)Ted

I have a feeeling it is firmware related. Granted I was doing the install in about 10*F weather so my brain may not have been functioning very well, but I went through all of the connections and I'm 90% sure they are good. I'll let you know how I make out tonight.Kenny

Success. Sure enough I plugged the bypass into the computer and it was the GM1 firmwared. Updated the firmware, did a system reset, and sure enough it programmed like a charm. The only thing I had to change was driver priority. I originally turned it off (thinking it would unlock all on 1 press) but it ended up throwing it all off. 1 press did nothing, 2nd press did driver door, 3rd press did all doors... lol. So I turned priority unlock back on and everything was great. Started up, tach learned, unlock worked, lock worked, factory alarm arms/disarms, trunk release works, brake input works. Thanks for the help guys!Kenny

compustar + idatalink blade = pricey, but the best total integration solution. Ted

That would be my choice now, but the original install was done before I was able to get compustars. I think I've used the blade bypasses on every car that needed one since I started doing compustars.. lolKenny

are you using the TB or the AL? Ted

Depends. Because I don't physically stock anything, if the car is not data for anything but immobilizer I use the TB (cheaper). If it is data controlled convenience then I fork out the extra few bucks for the AL. Either way, I love them... lol. I'm very anal when it comes to wire management and the blade modules make it so much easier. Its 1 less item to try and tuck away. Now I just can't wait til the CM7000 so I don't have to keep stuffing extra relays for any 2nd ignition/accessory/starter...haha.Kenny
