Might have a solution for your problem... Upgraded to 1.3 release code and had the same symptoms - car running rich as ****. Solution was the MAP sensor calibration - the settings for

At total vacuum % was set to 147 and the Rate % was set to -47 - in the newer firmwares (I think this applies to 1.2.3 too) this should both be 0.

Reset this and the car ran fine again.

Edit: I missed the part with the fried injector drivers - I leave the rest in here anyway, as it might help someone else.
