Ist doch scheißegal
Hier mal eine Beschreibung aus einem Forum:
This clever device incorporates many functions into one compact unit. It’s exactly the same size as the DC turbo timers and is packed with both useful and fun features; it has an easy to read flat screen display that is fully back-lit at night. The functions include a power read out display that shows the amount of power the engine is producing, dash modes which time your speed from 0-50mph, 0-100mph, 0-200mph, 50-100mph and 100-200mph, it can time you over distances of 1/8 mile or ¼ mile, and also has an inbuilt speed jumper which removes the 112mph speed limiter.
Installing the Power Meter SJ is simple requiring only basic crimping tools; ECU maps are supplied with the kit to help you in locating the correct wires to install it successfully.
