I’m curious about the references to the transmission ratios. I’ve got a PFL car that I’m considering changing the gearbox on, to a FL ratio. Will it not work without the tune?

Thanks, Peter

the car will run and drive fine, but cruise control will not work without updating the gear ratio tables

Here's a Weird one,

I have a FL w/ PFL trans, does that affect the cruise control? Been having some issues with it.

Still doing these, have a few in stock

I can do S, JCW, GP1 code, or even JCW automatic code (euro version) although with the auto it would probably only work well with the later asin trans
