Selling all the stuff I have to make your own ECM chips. I have a UV chip eraser for the older non-flash chips, a Pocket Programmer III USB this is the chip "burner" or writer and a Moates USB ALDL connector to hook a laptop to your auto. The software can be downloaded to make the modification to the chips, I used Tuner Pro. Also included is a custom "quick change" 7747 ECM this has a lever chip connector to quickly swap chips without having to fiddle around with the chip carrier until you get the final results then just swap in your regular ECM. I also have a handful of 7747 chips that are blank. Thinking $400.00 for all plus shipping. Working on getting it all rounded up to get a pic.
