log boost with JDM MAP sensor (updated instructions) - evolutionm.net
apparently USDM Evos have a 1 bar MAP sensor that can only measure up to 2.2 psi of boost. However, the JDM Evo 9 uses a 3 bar MAP sensor that can measure up to 32 psi of boost.
So far they're using this jdm evo 9 map sensor as a boost controller.It's pretty acurate from the posts i read about it. But I guess it doesn't meet my needs when I go over 32 psi, will it?
my car idles like if i had an old big block chevy in my car...Totally does not sound like an evo, but it idles fine( just really f'ing loud ).
So John you're saying that this evo ran on stock ecu with no maf what so ever?
