Urgent input needed! MGP pegging to -99

Recommended Posts

I'm on location at a client's business trying to help them get their Storm G4 mapped.

There has been a long list of problems, but I am stuck on this one.  My distributor sounded a little stumped too.

When I turn on either (separately) the internal MAP sensor on AN V channel 5 or an external sensor (currently on channel 2) the MGP readout pegs to -99kPa.

I have reinstalled the updated firmware and restored the ECU to factory settings.  The external sensor (a 3bar Delco) will sweep the voltage fine.  The internal MAP sensor runtime value sits at 4.78v and doesn't move.

Could this be an indication of a faulty unit? Or could I have missed something in setup?  This is my 7th Link setup procedure with the first occurrence of this problem.

Thank you for your help!
