I am hesitant to post this as i know its been flogged before. I have searched and read etc etc. Lots of great info, this is more of a sanity check.
I have a 2002 TB with the original 4.2 thats right at 190k. It has a fair amount of mid/upper engine noise and I can tell power is dropping off. Things are not great.
I scored a dressed 2007 4.2 with lower mileage. I got everything. Complete harness, p12 pcm, manifolds, fuel rail. Even got the bit of harness that goes into the blue connector and goes through the firewall.
My skill level: I am comfortable with everything. The pulled out engine will most likely be repaired and put in a 49 chevy car with a colorado manual trans.
I am comfortable either splicing or repinning the blue connector. Everything else just goes together right?. I am aware my p10 ecu will work with this engine but I want the P12 because its more tuner friendly and I have everything so why not.
My questions are will HPtuners throw a mismatch vin/os error if I put my current vin into the P12, can turn off the SAIS codes and run my blockoff plate, and can I do the fan stuff to put the LS1 fans on? Am I missing anything huge here? Its all class 2.
I should mention I am not partial to efilive or hptuners, whichever will do the job the best here. I am also open to sending the PCM off to have what I need done, done.
