We are now offering an OBD2 reprogramming device which allows you to flash our custom programs into supported OBD2 GM ECUs without having to remove the ECU from vehicle to send to us
This is NOT an editor (like HPTuners or EFIlive), it is for flashing only, you can't change any parameters yourself. We modify the program for your specs, you flash it into the ECM.
The calibration format is encrypted and the software write capability is VIN locked (you can only program a calibration into a module with same VIN).
This is to prevent recycling of one of our custom tunes into unlimited number of ECUs. We can, however, email you serial keys on case-by-case basis for you to change the VIN in an ECM, for $50 each.
We can also provide a factory GM calibration for the given VIN free of charge. So in addition to flashing our custom tunes, you can flash back to stock.
The cost to rent the cable is $50 above the cost of the tune with a $300 deposit on the cable. We refund the $300 when the cable is returned
