Stock traction control

On the VVT-i, its a momentary switch that turns it off. I dont think that by just bridging the connections it will stay off, although I haven't tried this. I'll try to remember to hold the switch in before I turn the ignition on next time I get into the car and see what happens. Although I don't know how the ECU would interpret the signal if the switch was permanantly pressed.

 

If you remove the trac fuse on a VVT-i it interferes with the operation of the drive by wire throttle. Meaning that the trottle doesn't work for the first 2/3rds of its travel. It also increases the idle speed up to about 1200rpm.

I think Pete Betts should design an interface box to allow "sticky" settings for the stock traction control, so once off it stays off even when re starting the engine. Possible Pete??

I was trying to find the post Chris. I am sure someone had done this about three years ago.
