3 Bar Map / 749
I have done a search.
I'm looking at picking up a 3 bar map for a reasonable price, and am wondering why I can't use it with the 749?
The MAP sensor produces a 0-5V range starting at approximately 1 bar below to 2 bar able atmospheric pressure. Versus the 2 bar which goes from 1 bar below to 1 bar above atmospheric pressure. Doing a little fiddling in TunerCat why can't I just scale the values from the 2 bar to the appropriate values for a 3 bar?
No coding, just have a post it note next to my laptop while I'm entering numbers.
