superchip function?
What parameters of the ECU does the superchip change? Does it alter electronic transmisssion shift points, injector dwell, ignition timing??
Will it affect drivability and general engine wear? 1992 F-150 E40D/5.0 Litre with Air, 3.55 posi. Thanks.

superchip function?
Once installed, it overrides the original ROM in the ECU with its own, which we program. The chip remaps the ignition curves and advances timing curves by anywhere from 3-8 degrees, depending on load and rpm. The fuel curve is remapped by an average of 2% leaner than the original curve, mainly because the factory settings are set rich in order to cool the catalytic converter for low-grade fuel. High octane gasoline burns more complete and cooler than lower-grade gasoline. We trim the excess fuel based on high octane gasoline and by doing so we create a better air/fuel ratio, which equals more power, i.e. more efficient running engine.
For electronic transmissions (most 94-up cars and trucks), the line pressure is increased, firming up shifts. Shift points are optimized, controlled by mph at partial throttle and by rpm at wide-open throttle. The shift delay is reduced, allowing gears to engage quicker and torque convertor lockup parameters are adjusted.
This information, and more, comes from the chip Frequently Asked Questions page I put in our online store:
