Anyone ever had one that won't allow a programmer to reflash the ecu? We have a 2006 Z71 with the L33 and it won't accept a programmer at all. My son took it to the dealer and they couldn't reflash the ecu. We want to change gears but can't until the programmer can be used. Any ideas other than the $775 ecu they said it needs. It runs fine. Just can't do anything with it. The vin number showed up on a superchips programmer but it will not communicate when you try to program.
