So you're using the original distributor for the TBI system, and the knock sensor?
What year is your truck?

My truck is 1986, but I added a TBI harness out of 1990 suburban. Yes I am running TBI distributor & knock sensor. I originally did this to controlling my 700R4 but have plans to go with a 4L60E or 4L80E without having to buy an expensive transmission controller. controlling timing and fuel pump was a bonus. would work better if I had a theottle position sensor.

That's interesting, I didn't think that any of the ECM would work if you didn't have the whole system.
I've been worried that I might have detonation that I can't hear because of my poor hearing, and I've been trying to figure out how to use a knock sensor without the ECM.
Very interesting indeed.
