Where To Go for Mitsubishi Evo SST Transmission Tuning

The Mitsubishi Evo, equipped with the twin-clutch Sportronic Shift Transmission (SST), makes just about any drive capable of cracking a smile. Both the Lancer Evolution X and the Lancer Ralliart were available with the SST transmission, and while many maintain that manual transmissions can’t be beaten, this dual-clutch transmission offers undeniable performance prowess. Acting in essence as two three-speed transmissions connected to the same output shaft, the SST transmission proves its place in the performance automotive scape with virtually instantaneous shifts with little driver effort. No matter how good you may be with a manual transmission, this transmission is simply designed to shift faster.

Understanding How Transmission Tuning Helps

To understand what transmission tuning can do for you and your Mitsubishi Evo equipped with an SST, you should first understand the basic principles of how these transmissions work. As we covered, dual-clutch transmissions operate like two separate transmissions that share an output shaft. They can engage two gears at once, only engaging one clutch at a time to ultimately move the vehicle. So, if you’re rolling in first gear, second gear is already pre-selected by the second clutch. The SST swaps between clutches across alternating gears to make lightning-quick shifts possible. The timing of these shifts in reference to engine RPMs has everything to do with performance and efficiency, and that’s exactly what is altered with an SST transmission tune from Boostin Performance. Altering these shift points takes the one-size-fits-all transmission program and tailors it to you for a fully connected experience.

Further to this, if you have a highly modified engine, it’s worth noting that the factory transmission tune will no longer pair well with the amount of power you are creating. A proper transmission tune helps to ensure you can take advantage of all that power reliably and with confidence.

Eliminate Gear Hunting in Your Mitsubishi Lancer Evolution MR

When a transmission is optimized for fuel efficiency from the factory but you’re driving in a way that demands power, you’re likely to get a scenario where the transmission “hunts” for the right gear to balance performance and efficiency. While that can be good for the average driver to maintain fuel efficiency, drivers who demand more performance out of their vehicle will find those excessive shifts to be less than endearing.

However, if you’d like the convenience of an automatic transmission with driving dynamics tuned to your drive, get in touch with us at Boostin Performance to see how we can get your SST tuned to your liking. We can also tune the shift speeds of the individual drive modes, making even your manual mode a custom fit for you and your driving style.

Smooth Shifts Vs. Fast Shifts - How the SST Does Both

Those who are attuned to the mechanics of transmissions might be curious about how the SST manages to provide a smooth driving experience with such quick shifts. After all, the engine wouldn’t be given enough time to fall in RPMs between gears, causing an abrupt change in engine speed and a noticeable jerk in the car known as shift shock. This is managed by the implementation of drive modes that change the shift timing of your Evo’s SST. Normal, Sport, and S-Sport drive mode allow your Evo to seamlessly transition between comfort/efficiency-optimized shifts to performance-optimized shifts. To mitigate shift shock for normal driving, the SST can inflate the shift time to allow the engine RPMs to fall and slip the clutch to better mesh with the next gear. Sport and S-Sport modes shorten the shift time for more performance-centered driving, with shift shock being very present in S-Sport mode. These two performance modes can even enable engine braking, making the SST a great tool for mountainous rides.

How To Equip Your Lancer Ralliart With S-Sport Mode

From the factory, Mitsubishi Lancer Ralliart models were not equipped with the S-Sport mode found in Lancer Evolution X models. Instead, Ralliart models are given “Normal” and “Sport” models. While those can offer adequate variable driving characteristics for many drivers, there’s no denying the extra edge S-Sport mode offers. If you own an Evo X with the automatic SST, we at Boostin Performance can get it equipped with S-Sport mode to help you dominate the track.
