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.

I am not familiar with the pro-flow sensor. Does it use sample tubes? If it does you are fine if not get the correct electronics.

Dont use a 93 cobra sensor unless you are using a 93 cobra ecu. The 93 cobra sensor is actually calibrated for 19# injectors and the 93 cobra ecu makes it work with the 24# injectors.
