While tuning engines I often times have people ask me what they can do to ensure their engine remains reliable and making good power for as long as possible.
Besides the obvious hardware requirements/clearances and general maintenance there are a few key sensors that can be incorporated into the ECU and calibration/tune that can not only increase engine performance but also save an engines life if there is something as simple and common as a fuel pump failure.

This little article goes into detail about the Fuel Pressure sensor and how it can be incorporated into a calibration by the tuner to not only help your engine run efficiently but also keep it safe and healthy. This little read is HIGHLY recommended for anyone that "pushes" an engine on the track or the street.

Fuel pressure sensors, gauges and engine safety explained



Explanation: Fuel injectors flow a given amount at a set fuel pressure; more pressure - more flow, less pressure - less flow (for the same given injector open time). If your engine has been tuned with 50psi fuel pressure/injector pressure and 6 months later your dirty fuel pump starts to die fuel pressure will fall off first at high RPM/high engine load. This is where the pump needs to flow the most fuel, this is also the most vulnerable operating range for an engine so any loss in fuel will quickly cause a lean condition leading to damage.

Solution: Assuming your car is using a proper motorsports ECU such as; Motec M1, AEM Infinity, Haltech, Bosch, Pectel, etc we would incorporate a 3 wire fuel pressure sensor into your calibration aka “ecu tune” in a number of helpful ways listed below.
