Two MAP sensors on Micro?

[btg]

On the megasquirt, there is an option to use the on board MAP sensor as a baro sensor and then wire in an additional MAP sensor in to allow for real time barometer corrections. I know that the microsquirt does not have any on board MAP sensors, but is there an option to have two MAP sensors wired in through the harness for the same purpose? One sensor would be hooked to the plenum and the other would be open the to the atmosphere.

Microsquirt also allows the use of dual MAP sensors. You don't have to hack anything to do it. The speed density MAP sensor goes to pin 24 and the ambient MAP sensor goes to the spare ADC (pin 29).

Thanks for your help. I am planning on using the factory MAP sensor from the bike and a GM sensor for the baro. For the factory MAP sensor, how do I change the voltage vs pressure table? I didn't see in megatune where you could change the MAP calibration. It looked like I could only select from some standard GM and mega squirt sensors.

If you go, in Megatune, to Tools\Sensor Calibration, you can set two point response curves for you MAP sensors.
