question for ya Bill
 

Not sure if this is possible but after talking to you today, I had one of those edison moments ... lol. (burned out lightbulb tries to flash):crazy:
Anyway would it be possible to make a chip setting that basically enables the ebv valve, locks the tc, and drops the truck one gear above a set speed for use as a exhaust brake?
I didn't know if the settings are even possible within the software but thought it would be a really nice thing to have towing:yesnod:

Yes, it's possible. Using the right base strategy, we can use the EBV as an exhaust brake. We've done it on other strategies with reasonable success.

Not to Hijack too much, but I've heard some concern for the life of the coast clutch when using any form of backpressure brake on an E4/4R... any opinions on this?

It's my understanding that on a E40D things are little bit weaker than the 4R100 and I wouldn't generally use either to try and hold back a 15K trailer, but for small loads (2K-4K) it should be fine. The Coast Clutch is the smallest clutch pack in the transmission and can't handle too much abuse, at least how I understand it.
