I am finishing up a new rig and am trying to verify that I am going in the right direction here.
The motor is a 99 lq4 that I built into a 408. I ran it in my old rig with a tbss intake and a WARR DBC TB. In the new rig its going in, it is in a mid engine position so I converted it to DBW instead of trying to run a 10 plus foot long throttle cable. I picked up a complete harness, tac, pedal and PCM from a 03 truck. I have the harness all cut down and everything routed and hooked up. Right now it still has the tune in the PCM that it came with.
My main question right now is can I just dump my old tune in it and fire it off, or is there specific things I need to do to it before trying to start it? I am not sure what will be changed or modified with the older tune into the newer PCM, and if it will effect the way the DBW operates, or if it should just fire up and run like it used too. Everything I am finding is about going the other way....
I attached the tune from the old rig and the initial read of the new PCM.
