2010 camaro problems need ideas mods on car when bought - kooks longtubes, noweeds diverters, stock exhaust, rotofab cai, ECS big blower cam, c5r timing chain.
when full throttle in 3rd it would kick on the stabilitrack. never saw this before with other 5gens, but just disregarded it and threw some new mods on the car.
new mods - maggie 2300 w/3.8 pulley, connecting rod bolts, lingenfelter dual pump kit w/new fpcm, 65# FAST injectors.
Car ran fine till it got onto the dyno. where after a few flashes it wouldn't start. finally got the car started and put down bad numbers cuz i was afraid to turn the car off and flash it again. Got it home and things all checked out no CEL's had fuel pressure, got spark and tb was opening. Voltage seemed weird so I was checking wires. Seems the electronic cutouts had the wires melt on the dyno. Disconnected these and things didn't change. Then the other night I got on it in second trying to force a code or anything to happen and I got something. 7 codes popped up. Now I need help deciphering what they mean, if they are related and where to go from here.
P0108 Map Sensor Circuit High Voltage (Immature)
P0121 TP Sensor Circuit Insufficient Activity (SES) (History) (Immature)
P0575 Cruise Control Related Malfunction (Pending)(History)(Immature)
U0109 Lost Communication w/fcpm (Pending)(Immature)
U0121 Lost Comm. w/ABS Control Module (Pending)(History)(Immature)
U0140 Lost Comm. w/BCM (Pending)(History)(Immature)
P0121 TP sensor Circuit Insufficient Activity
thats how they showed up on HPT. Any and all help/advice is greatly appreciated.

Your HPT interface is fuxored...
FOR REAL...
Disconnect battery for a long a period and don't connect that interface again.. problem solved...
Happened to my tuners interface on my 5thgen... mine works just fine.
each and every time he connects his, ABS miscom will pop with any random other codes.

Yes the interface is the HPT box, you can send it to HPT for repair, but actually the one that is acting up just went there "fried" and came back like this...
SO...
When they say, never connect to any charging device your laptop while tuning, you should listen.

P0121-usually related to aftermarket camshafts
P0108-usually related to aftermarket camshafts
U codes-usually pop after a read or a flash in that all the modules on the same bus as the pcm are told to shut up this is the "loss of communication" part of the code and are perfectly normal.

Unhooking the cutouts may not solve the wiring issue. Where are they getting power from?
Did you separate the wires where they are melted together? [Before or after the plug]? If before, the circuit can be still shorted. I'd trace those cutout harnesses back to their origin.
If the tuner will link, check the MAP reading KOEO..A bad MAP may prevent starting...
