Although the new A/F gauge has this feature "out-of-the-box" (for A/F datalogging), you'd have to improvise something to get the readings from the MAP sensor in FreeFlyer's boost gauge set-up..... at least on the ones I have installed.
Worst case you have to trace the 3 wires coming off of the GM 3 bar map sensor and tap the 0-5V output signal.
