I have to say I'm pleased with all the nt710 offers, even though the interface takes a little getting used to, and updates took forever. I got the nt710 over the 520 or 624 because of the extra bi-directional things, plus I will probably get an E90 next... after I get an 8HP 1400 installed/working in the E53 after I break this fragile GM 5L40e, which is only rated for a 4,000 lb car anyway. The E53 is over 400 lbs heavier empty! Then I'll see if the trans-diff holds up, etc. This is a project car that I want fully streetable, and ultimately I intend to have a clutched supercharger and 2 turbos on it with the control system I'm building. That's why the H-beam rods, low comp Carillo pistons, high temp rings with plenty of gap, high temp bearings, etc.
Foxwell says my EWS is totally fine. I'm using key #2, and it's enabled and active.
Below are relevant pics from the Foxwell:
Finally, in the link below, there is a short video of the car cranking. I depress the throttle for 2 seconds, release it, and then turn the key. About halfway through, you'll hear the sound change when I depress the throttle again while cranking to ensure the throttle body responds correctly. I didn't see a video embed control and didn't feel like uploading it to YouTube.
Click the sound icon in the upper right of the video to hear it.

Unless someone has a genius idea that neither I nor any of you have thought of, I think I'm stuck pulling the head off and addressing the compression issue. Some of the valves leak some but I never thought it'd be enough to prevent it from starting. Once I have the head off, I'll re-lap the valves and try to make them waterproof, reinstall them, and try again.
Please, someone, come up with another idea; I didn't really want to take the engine apart again so soon.
I'll be back here in a few weeks and share whatever knowledge I've gained, even if it's only a sore noggin from banging my head against the wall.
The beatings will continue until morale improves...
