The OBD unlock solution available that allows the Yaris / Corolla to be programmed directly from the OBD port.

NOTE: IF you remove the patch (program a stock ROM in) the gateway OBD unlock will be removed. This will require the ECU to be unlocked again with a patch and our servers.

Server Authentication issues

If the gateway OBD unlock is unsuccessful due to server issues please wait 1 hour for the server to reset and try again. We are trying to improve the server reliability and as improvements are made updates will automatically be used.

If you have a server authentication issue, you can still unlock with a physical bypass cable and install the RaceROM patch after . After this is , it does not require server access, and OBD programming can continue unimpeded. This may end up being quicker then than waiting for the server to automatically reset.
