Does anybody know if the Transmission Control Unit from a Forester XT will work in the WRX CVT? I'm trying to find out if there is a way to eliminate the "step shifting" my CVT does in I and S modes. (The step shifting essentially eliminates any of the benefits one would receive by using a CVT) The transmission in the FXT doesn't step shift in I or S mode unless you use the paddles, or manual mode. If I can use the TCU from the FXT, that would be a simple fix, especially if I can find somebody to just swap with me. I'm a bit concerned about whether it would play nice with my ECU since it is completely different than the one in the FXT. Any info helpful.
i could be wrong but from what I've googled... i don't think you will be able to switch it in and make it work since it's a different set up... you might need to go to a shop that can reconfigure the ECU settings for this to work... at least from what I've read online it wouldn't work properly since they are mechanically a different system from each other... sorry...
Yes, that's what I was talking about. I've also emailed SOA and they say there's no additional programming available. Guess I'm just gonna have to wait for a tuner to tap the CVT. Gonna be a long wait...(fingers tapping...)
