V88 Knock Control activation problem

Recommended Posts

Hi all.

I've been trying to enable knock monitoring/control with no success. Each time I connect VTS to the ecu the knock setup immediately turns off.

I have read a few previous posts where people experienced the same problem but having tried the 1 or 2 suggested remedies i am still stumped. 

I hope someone can assist.

Ok, I found the problem.  There is some odd interaction (bug) between knock and DI pull-ups on DI7&8.  

For me this worked: 

Turn the pull-ups off on DI 7&8, do a store.  Power cycle ECU.

Enable Knock.  Store.

Turn pull-ups back on.  Store.
