Thread: Speedo Recalibration C1600

Do you mean the lock up happens about 85km/h? Can it be modified when lockup happens as part of a tune?

I am interested to get the recalibrator as with my 245/75/16 tyres, I'm doing 83 - 84km/h when the speedo reads 80km/h. As I drive a lot of 80km/h speed limit roads, I'm either travelling with the speedo reading 77 - 78km/h and the Auto not locked up or speeding just to get the Auto to lockup which currently happens right at 80km/h on the speedo (actually 83-83).

Happy Days.

I'm pretty sure the answer is no without significant mods. The 4th lockup is hardwired into the system for a particular rev range.

The auto trans people in Melbourne have a system which in electronic autos allows you to over-ride and create a mauual gear approach ie it will stall if you leave it in gear and stop. The TD5 electronic auto is a goer with this system

and with a compushift ecu you can turn it into a "flappy paddle gearbox" but it starts to get very expensive.

Is that the gizmo Ashcroft are selling?

I think so. Compushift is pretty common after market controller for gearboxes

I'm pretty happy with the way it works but I just like it locked up for better economy and at the 80km/h speed limit with bigger tyres than standard, I need to speed to get it to lock up.

Happy Days.

Joel, sounds like you have the same set up as me - I was getting annoyed byt being out by about 5-6kmh at 80 - especially up hills.

I don't know about compushift but you can get a heavy duty lock-up which will change it but that's lots of work!
