Possible bad unit

Quick backstory, I use the unit on my autocross car, installed last summer, unit has approximately 1200miles on it. Had the car at my shop doing some upgrades/changes to the car (different turbo, intake and suspension changes).

Drove it home, and the unit went from working fine, to just showing 10.5~ for the rest of drive home, approximately 8miles (drive is 11). Luckily I caught this and disabled lamba based fuel trimming and was fine to drive home on my map no problems.

Contacted toalan and he sent me the trouble shooting guide. Granted…I was suppose to be using these last handful of days to retune the car for a race this coming Sunday. Did the test today, both with as wired (fused and relayed as it should, and fully bypassed with direct power and grounds to battery) I get no output voltage on the green wire.

Is that a sign the unit is just dead?
