I am curious as to what parts/sensors will interchange with the D1s. For example we can use the GM AC Delco IACV (#217-437) in place of our overpriced ones when they go bad. Im speaking general things like sensors, waterpumps, starters, alternators and the like.

 

the thing is that even though you might be able to use them, they don't always work. There have been a couple of people on here that have used the Delco IACV, but still had to take it to a dealer to have it set, only to find that the ECU would not read it. I think there is a parts interchange on D-web under the tech section. If you want to try it, look there.
