MegaSquirt MAP

[Bruce Bowling]

Santi,

To change MAP sensor requires you to change it on the board, and use the 
code version which has the MPX4250 version of KPAFACTOR.inc, which is the 
lookup table which converts ADC counts directly in KPA.

As for running a NA car w/ a Turbo MAP - you can do it, but you lose MAP 
resolution. the MPX4115 yields 5 volts @ 115 KPA, and the MPX4250 yields 5 
volts @250 KPa (see the pattern in part number). But, in reality, you will 
probably never notice the difference in resolution, practically speaking. 
For your situation, get the Turbo MAP. For those just running NA engines, 
get the MPX4115AP version.
