A question regarding AL4 final drive ratios.
Just musing, but can the final drive ratio be reconfigured with Lexia or such. I know there's provision to reset the tire size but I mean how do they configure the box with different models ie" ratios. Is it done when the original gearbox ECU is programed?. That may explain why there are different ID numbers on the ECUs from the same manufactures. I have no idea, but its worth a thought when there's naught on telly.
