Using the Factory BMW T/MAP Sensors with the CM5-LTS

In most BMW applications with a CM5-LTS WMI controller, it is preferred to obtain boost readings by "teeing" into the factory TMAP sensor wiring. Below is the information on how to do this for several popular BMW TMAPs we have tested.

The numbers below are derived from a sample of one sensor each that we have tested. The numbers below may differ for individual sensors in different cars.
