    Years ago I joined a mexican tuner forum looking for a file.
    Unfortunately nobody could help me,but I think alot was the language barrier.
    They were very excited to talk with people from US about cars however.
    I would love to cruise down and hangout with them.

    I know AZ opened stores in Mexico and Brazil recently,and the computer usually has an option for the Mex engine version.
    I'll check tonight and see what happens when I try and order a pcm.
    Could it be as simple as buying a PCM from (efihead)parts store,junkyard etc.. in mexico and having it shipped here?
    I doubt customs would know what they are looking at,or if they did that it would matter.

    There wouldnt be any issues with customs, I have shipped a few PCM's across teh border.

    But if you are thinking of nuying a new PCM, it would arrive blank still requiring a flash.

    I'm sure there would be some interest in some of those 128 lb/hr Brazilian ethanol TBI injectors as well.

    Actually,you can order pcm's flashed or unflashed from Autozone.
    Unfortunately,while i'm showing a mexican 1ton with a 5.7 until 2004 in the computer I don't have availability to order a pcm for them.

    Oh thats cool. Do you just give them a VIN or something? Thats really cool. I dont even know if yoiu can get a flashed PCM from GM, unless its a PCM from GM Performance Parts.

    I spent some time searching Mexican classified ads and GM dealer inventory. Couldn't locate the combination of year plus engine plus VIN listed. Still, it's probably worth following that route if nothing else shows up.
