Versa Tuning! CVT Tuning! 03.08.10
So we had our first run in with a Versa the other day. Martin brought his Versa by a few months ago and we started figuring out the ECU. The issue we were most worried about was the CVT transmission. Unlike a normal car on the dyno where we watch the numbers based on RPM, we had to use MPH for these calculations. We were also worried about how to tune a car that under wide open throttle conditions really just sits at one RPM.
Things turned out surprisingly easy though, and our software has the control to accomplish tuning even on a CVT transmission car as long as the dyno is able to run MPH rather than RPM. Martin ended up with almost 5hp gain at the wheel and thats not bad considering these cars are rated at 107hp from the factory.
