I am looking for a deal on a EFI "ECU-Blue" module for my 94 Pantera 550. Can someone help me out, or point me in the right direction. I Recently bought the sled and can't afford to pay $$$ that the dealer wants for a new or even reconditioned unit for that matter. Also, are the ECU modules around this vintage identical (except for the EPROM chip). In other words, if I found a ECU from a different Cat (but looked the same) could I put my "Blue" EPROM chip on it (assuming my EPROM chip is good)? Is there a company that I could send it to for repair other than Arctic Cat? Thanks in advance!
