Emanage Ultimate Problem with Throttle Position

[burmjohn]

Have a problem with the Emanage Ultimate reading the Throttle position at 100% with the ignition in the ON position without the car started. The car will crank but not start. I'm using Greddy's Plug-n-Play harness.

If I reconnect the the stock harness to the ECU without the emanage, it starts right up. When I reconnect the Greddy harness, it'll start the 1st time but not after that. The pull down tab for throttle parameter settings, shows that the "now" settings for voltage at 5.07v at 100%. When I try to clear the values, it resets back to the 5.07v 100%. Because of this, the car wont start due to no fuel. I'm at a loss at what is causing this. Spoke to Greddy and they have no idea other than it might be a bad harness or ultimate unit.

Any help would be appreciated.

I have no experience wiht emanage, but with Megasquirt a lot of errors especially lost or changine values has been fixed by grounding the chassis, easy enough to try
