Sticky MAP value
I've got an MS1 v3 hooked up to megatune and clt, iat etc are all working, however the map value is stuck on 185 kpa. I've been after a less laggy turbo setup for awhile, but 30 odd psi of pressure without the engine even running is awesome!!!
It's the standard 21 psi map sensor and it doesn't change value when I blow through a hose into it. Has anyone had this problem before?
Cheers

The sensor might be busted... or the circuitry connecting it to the CPU.
Check the pin that goes to the CPU for voltage... Apply vacuum or pressure and check again...
If the voltage isn't changing, the sensor is probably busted.
