What gears does cruise usually work on a factory t56? Vette or ctsv, or g8 gen Iv Im having troubles creating a custom os for a 2009 Colorado 5.3l to run a t56, I have access to a lot more tables then most poeple have in the tune
Anyway I have removed the t42, and I have reverse lockout working speedo works good, clutch switch working properly, no dtcs. After changing the gear ratios in the tune to match my mn12 05 gto t-56 I got cruise working above 25mph in 3rd, 5th and 6th. I'm using a gen Iv e67 PCM
Cruise will not work in 1st, 2nd, or 4th??
What speed and what gears work with cruise on a factory 06-07 ctsv, 08-09 g8, as they have the exact same gear ratios as me! Also interested in gen Iv 06 and up vette or ls3 camaro factory cruise with tr6060. Please post up how your stock car works. As someone told me it's normal up not have cruise work in 1,2,4?? I can see not working in 1,2, maybe 3rd, I'd expect 4,5,6 to work though?
Any ideas why mine doesn't work even after correcting the gear ratios?

In many cases I've seen, 25mph is more or less a default minimum speed for cruise operation. They usually won't work under that. Now why it's not working in 4th is another issue...

I haven't played with any of those vehicles, but was wondering what the cruise status PIDs are showing? Something like STATE 00 (not sure which software you are using but this is in EFI Live). Since you have it working in the other gears, it might be interesting to see which PID changes when your in 4th gear to help narrow down what's going on.
Is this using a E67 ECM?
