Do the pre 97 ecus allow you to remap using a 3 bar map sensor? I know that the atmospheric pressure would be out a little, but is there a way to do it?

I am thinking that that if you want over 17psi mapped, you need to get a Link ecu.

When I compared the voltages, in johns fuel cut defencer thread they were way out.. Does the solenoid change make any difference as well?? as the newer one has a three port boost solenoid...

Can we not just adjust the map sensor scaling value in the ecu as discussed??
