My MCX display no longer seems to be working and I need to change my mapping in MCX Gen 3 for bigger injectors.

Does anyone have wiring schematic for USB to connect directly to GEN 3 fuel box using Megatune 2.25 without Display? Want to avoid downtime for sending to reprogram.

Hi, I see that no-one has replied to your post, did you ever get your display to work again? Just wondering as I have the same gen 3 and the display that I purchased for it has never worked correctly, voltage jumps around from 9-11.5volts and my stock dash background light flickers when this display unit is plugged in. Anyway, I was told that there is no way to change mapping without this display unit to connect your computer.
