Wideband O2 Sensor

The Pro128 ECU utilizes twin built in UEGO drivers for highly accurate wideband input control. Factory recommended warm up strategies are also in place to prevent premature failure of the wideband O2 sensors. We have found that MOST of the failures with aftermarket controllers are a direct result of improper heating strategies, not leaded fuel use. Our racers have reported SEASONS of use without failure! ProEFI utilizes the commonly available and inexpensive LSU4.2 O2 sensor. This kit contains both a sensor, and a cable to run back to the Pro128 ECU.

EBPS – Exhaust Back Pressure Sensor

When using forced induction, exhaust flow becomes even more important due to the high volume of exhaust gases being spent. This is particularly important when dialing in a turbocharger’s exhaust housing and exhaust wheel combination. This kit contains the parts needed to feed exhaust back pressure back to the ProEFI ECU for calibration feedback and tuning information.
