Product Details

Nearly all BMWs use a speed sensor to monitor rpm, ABS and traction control/ASC operation, windshield wiper speed, cruise control and of course the speedometer. In fact, the speed sensor is one of the most vital sensors on the car if you want to maintain normal vehicle operation. For the engine, the DME relies on the speed sensor signal to set the maximum rpm in each gear. On the E36 chassis we have seen speed sensors melt from heavy and continuous track use (endurance races). Without this signal, the DME defaults to a preset RPM limit (usually 5,000 RPM). Other problems can arise if you have re-wired the car for racing use or with an engine conversion. During a conversion, if you do not properly re-wire the signal going to the DME it will think the sensor is missing or failed.

What we have done is modified and removed the lines of code in the chip that require the speed sensor signal. Instead the DME relies on the specific parameters and data points within the chip itself. The speed sensor remains installed in the differential cover since other parts of the car require its signal. This is not a catch-all answer to every problem that crops up with racecars or during a engine conversion. But like the other parts we have developed, it makes the job– and life – a lot easier.
