Question CVT recalibration for more low speed torque ?

Hello,

I am interested to know if anyone knows about the CVT calibration for the 08 Jeep Patriot, and if it can be calibrated to provide more torque and faster response, especially at launch.

Or in general if there are any tools available to modify the CVT calibration.

thanks,
steve

An inherent weakness of belt CVTs is that they can't handle high torques at low speeds. You can dig thru a ton of intense SAE papers on the topic if you want, but that is the reality. The fuel and spark are pulled back pretty aggressively at low speeds in ALL belt CVT vehicles. A quick glance at things like Car & Driver comparison tests will show you that the CVT-equipped vehicles almost always are dead last in the 0-30 MPH sprint (b/c they can't handle launch torque), but often are the fastest 0-60 (where the CVT's ability to maximize power delivery comes into play).
