Does the installation of one of these void your Porsche warranty? Can they be removed when you take the car to the Porsche dealer for service?
Most systems would void the warranty, even if you have a new tuned ecu, when you put the other back in Porsche can see that the ecu thats in have not been used for a long time.
I was really close to get me a new ecu but i backed out waiting for my warranty to expire.
The i got issues with my coolant sensor, Porsche told me they will fix it under warranty, if there is no tune on the car.
To change the sensor the engine has to come out......
MTM say that they will take over the engine warranty but how much truth there is in those words i dont know.
