I am bench flashing a 02 Silverado ECM to delete vats and things so the engine can run on a stand. I read the entire ecm, saved the file, did the recalibration, resaved a new file and im now unable to re write the ECM. The editor gets stuck on erasing now and wont finish the re write.. Anybody else have this issue ever? 100% stock tune, minus me just disabling the VATS control.
