TS Performances MP-8 Luxury Edition computer module can improve the fuel economy and performance of your Mercedes Diesel powered passenger car or SUV. The MP-8 is a simple plug-in module that communicates with your Mercedes engine computer to calibrate and optimize fuel distribution under a variety of driving conditions. The result is improved efficiency that delivers 2-4 mpg better fuel economy and up to a 50 horsepower increase. Based on the current cost of diesel fuel and a 15,000 annual mileage average, Jeep CRD owners can save hundreds of dollars annually with a 2-MPG increase. This makes the MP-8 one of the only performance products that can actually pay for itself.
The TS Performance MP-8 Luxury Edition module fits all 2007-08 model Jeep Grand Cherokee CRD. The MP8 module is easy to install and is compatible with all of your Mercedes factory equipment. Because the MP-8 is a plug-in module and not a downloadable tuner, it does not rewrite your factory computers tuning and can be easily unplugged if you take your vehicle in for service or when your vehicles lease agreement has expired.
Furthermore, the MP-8 can never be outdated, as it can be easily upgraded with new TS Performance programs that become available and can be used on a variety of other diesel applications with new connection adaptors available from TS Performance.

Tried three different modules and all produced electronic throttle control and check engine warning lights almost immediately (usually on the second start). Works well until the warning lights comes on and all power is lost. Product does not seem to have been thoroughly tested as it was not able to fool the computer when altering the signal from the fuel rail pressure sensor.
