I can arm it but not set it. However, works fine in 3rd and 4th.How does the car even know what gear I am in? Weird.Cheers Link to comment Share on other sites More sharing options...

It only turns it off after the wevs raise a fair bit but speed stays the same, it realises something is wrong and turns it off. That's why I think there is no sensors for each gear.

Have you changed tyre size/diff gears? Link to comment Share on other sites More sharing options...

Diff changed from 2.73 to 3.73 and the PCM has had the ford factory manual programming put on with VCM before re-tuned on the dyno with xcal. The switches work. Cruise deactivates in 3rd 4th when depress the clutch or brake. Here is a curly one. The cruise worked once in 5th but not 6th. Nothing was changed. Now doesn't work in 5th either. Only 3rd and 4th. 1 Link to comment Share on other sites More sharing options...
