    So,

    I just swapped my computer for the Diablo sport one-No reflash, just the computer so far-and when I fired the beast up, I got a CEL...
    P1645.

    The car is running fine and the code went away in the computer log soon after, yet the light remains....


    Ideas?

    I am sure it is. There are only 2 options...1) thew PCM is faulty and has an issue with the system. 2) I messed something up or bent something during the swap. I am betting on the latter...

    HHP. I will do it under daylight tomorrow so I can watch all the cables that connect in closely.

    What tune was loaded into the new PCM? Stock or something custom?

    Swap back to factory PCM and see if problem persists. If it goes away, could be a bad load on the aftermarket PCM

    UPDATE- I redid the install with the Diablo PCM and all is fine now....I think somehow I had a bad connection. Thank you for all the assistance.

    ANother update...I spoke with the vendor afterwards and they said that this is actually a very common issue...BUT since most of the time the swap is being done at a shop they simply reset the computer system manually and all is well before the client gets their car back. Nothing to worry about, the computer simply needs to re-learn and sync with the other computers on the car.
