I'm not getting any signal from these sensors. I don't see any activity when cranking in the composite, tooth or engine logs. I must be missing something obvious...
Kit car w/ Ford/Yamaha SHO motor.
Pre-assembled MS3.57/MSX
All new wiring.
LS1 coils w/ no other ignition bits.
Looking for sequential ignition.
Existing VR Crank Sensor w/ 36-1 tooth wheel - (Wired to 3.57#24 TACH IN White in shielded wire In 'Crank' Tach input)
Shield and Ground - (Wired to 3.57#1&2)
New Hall Cam Sensor - (Wired to MSX#32 Cam input Dark Green In 'Cam' Tach input)
12V power and ground to sensor ground
Is there something obvious I can check? I have sequential ignition, dual wheel and cam in on MSX CAM enabled. Even if the other settings still need tweaking, shouldn't I get SOME signals when cranking?
Thanks in advance!
Edit: Also, I've checked the VR crank and Hall cam jumpers and pots.
Update: I've probed the signal wires from the cam and crank sensors while cranking. Cam shows 0-12V and the crank sensor shows .4V. It looks like both these sensors are working, but not getting received correctly at the MS. Could this be a faulty unit? I'm attaching the msq.
No cam or crank signal

Re: No cam or crank signal
You need to change the wheel setup to "dual wheel with missing tooth".

Nice! Now we're getting some data. This was the spark I needed... 
I'm going to start looking through the rest of the setup now. Here are the current logs.
