MASS air flow question..
On a 1990 coupe. What i have is a chrome pro-flow 75mm housing, and sensor, calibrated for the 24's i have on the car.
The electronic pro-flow sensor part went bad, because it would'nt run right.
when i put on my factory oem sensor on, onto the 75mm housing, it runs fine, just turned some 12 sec times with it actually.
My question is, will this totally ruin the calibration, and cause performance loss?
will ecu think i have 19lb injector's?
If so, do i order one from pro-flow or somewhere else? how about a 93 cobra sensor?
Thanx alot fellas.
