27 JULY 2022 UPDATE: SST MOD VERSION 2 now available, included in the 15% plus ShiftModv2 Upgrade pack is now 0,7,8,9,10,11,12, and 15 % extra clutch pressure CFF files. You can flash between whichever Extra Percent clutch pressures you feel like driving that day, takes just 4minutes to flash your transmission before heading out. The ShiftMod upgrade option includes higher rpm rev shift points for Normal mode, higher revs in Sport mode, and even higher revs again in S-Sport mode. includes some pretty awesome rev-matching early downshifts in sport and s-sport too. **Free Upgrade if you previously bought the ShiftModv1 upgrade option. ***8% to 12% pack is only available if you purchased Both the 15% option and the ShiftMod option.
SOFTWARE UPGRADE FOR YOUR STOCK SST AUTOMATIC GEARBOX TRANSMISSION ECU
SUPPORTS 2008+ MITSUBISHI EVO X and 2008+ Mitsubishi Lancer RalliArt
• FASTER AND CRISPER GEAR SHIFTS!
• BUILDS 19PSI+ BOOST ON LAUNCH CONTROL (USING NORMAL REV LIMITER – EVEN WITHOUT SPARK CUT)
• INCREASED VEHICLE ACCELERATION DURING GEAR SHIFTS. OUT RACE OTHERS DURING GEAR SHIFTS.
• ROLLING SUPER SPORT MODE.
• INCREASED CLUTCH PRESSURES, LESS CLUTCH PLATE WEAR.
• INCREASED GEAR SHIFT PERFORMANCE IN ALL MODES.
• WORKS WITH ALL TUNES INCLUDING TEPHRA X MOD.
• DOES NOT AFFECT YOUR CURRENT TUNE and DOES NOT REQUIRE AN ECU RE-TUNE
The Awesomeness of reflashing into the stock SST transmission is that this increase in clutch pressures is quite far away from your tune. So basically you will get faster gear shifts. Crisper shifts, and less clutch wear. And increased throttle responsiveness when in s-sport mode. No downsides. Basically.
• COMPATIBLE WITH AFTERMARKET CLUTCH PACKS (High 500+HP cars and AfterMarket Clutch Packs use 0% or 7% extra clutch pressure and soften your clutch shifts via our SST tuning guide pdf)
PreRequisites: WINDOWS (any version) + OPENPORT 2.0 CABLE
EvoScan SST TCU MOD ROM v1 CFF file available $37 USD (one per each vehicle VIN)
We provide the upgraded cff software files, and we provide the stock software CFF file to go back to stock too.
Emailed Daily at 6PM NZDT, please email us if you haven’t received your SST TCU files within 48 hours.
We are now upgrading everyone to the B151 MOD CFF, including RalliArt SST vehicles.
B001 and B151 are identically the same rom, B151 just has 4 tiny updates (less than 5 bytes of code change), B151 was updated by mitsubishi in 2011 for safety when the brake pedal is depressed the clutches open, so in case the throttle gets stuck down, the clutches will open, so therefore B151 is safer.
• $37 USD For the Modified CFF SST TCU ROM file you can safely flash to your car using PassThruCAN Windows7/10/11 software and an Openport 2.0 cable. one licensed rom per vehicle, two vehicles will need 2x $37. please provide your VIN number in the comments when ordering. You can flash your original CFF file back to the Car if you don’t like the increased clutch pressures.
• additional optional extra $20 for Engine SST Tuning Guide PDF v1.2, this includes all the learnings from the Hundreds of hours of learning during SST dissassembly, Logging internal SST values, and Testing SST TCU modifications over the past 9 months since May 2021.
– SST V1 includes TWO MAJOR FEATURES, never before seen on a Stock Factory SST ECU
Activate S-SPORT Super Sport Mode at any vehicle speed at any time when driving, and the mode switch works instantly without delay when switching up and down through the 3 modes.
Perfect for those Unexpected ROLL races, where you need S-Sport mode quickly.
Increased Master SST TCU Clutch Pressure by 7% across all 3 modes: Normal, Sport, S-Sport.
HIGHER ON-COMING CLUTCH PRESSURES PROVIDE; INCREASED OUTPUT SHAFT TORQUE, FASTER SHIFTS, HIGHER TORQUE INERTIA OUTPUT, HIGHER VEHICLE SPEED and HIGHER ACCELERATION*.
*Higher acceleration m/s2 was noted during the first 2/3rd phase of each quick gear upshift, of course you will have slower acceleration during the last hookup part of a gear shift because this is where the dynamic torque and static torque lock-in occurs and in the acceleration there is not as strong, this is how DCT’s work.
Includes SuperSport Mode and Launch Control for Ralliarts (yes Ralliart’s can run B001 or B151 CFF ROM files as well)
– SST V1 also includes a preview Version of the new EvoScan v3.0 that has built in SST Teach In Calibration for the SST transmission.
The TC-SST factory TCU rom is a Tricore, and dis-assembly was done using github’s Ghidra software by the 3 of us for many months starting in May 2021. Special thanks to Nikolay from RU, Special thanks to Hamish from EvoScan, and Matt from New Zealand, for all the efforts in cracking open the SST TCU greatness and hundreds of hours testing.
DISCLAIMER: It is the responsibility of the owner to regularly change your SST OIL with OEM SSTF-1 or a compatible DCT oil such as Castrol Transmax or Penrite DCT. Limitless Designs Limited will assist you where there are any issues with the software, flashing new firmware or flashing back to stock SST rom. SST MODs are deemed safe because they are still within the parameters of the existing transmission, the clutch pressures increased are still within the confines of the operating limits both software and physical sst transmission wise, and the research team have studied many other studies on DCT transmission software engineering and working parameters. We tested our mods for 9 months using two New Zealand based 2008 JDM EvoX vehicles before releasing the mods, we have already found the variations across models and versions so it is safe on all EvoX and Ralliart variations. We have researched that the stock clutch seals can hold more than we are increasing and that the software and sst still retains its factory limit of 242 psi (16500 mbar), we have tested that moving to S-Sport whilst driving is also safe, and that it operates no different than if you had manually moved the manual gear change yourself. Anything that happens to your SST could happen with or without the mods. Limitless Designs Limited is only liable for up to the cost of the purchase of the software mod. If you have any questions, please direct them to Hamish Ahern on facebook.
1 . “Best money ever spent. Going from Sport mode only to supersport then to this is like an entirely new transmission. Best money ever spent.”
2. “Fantastic, I have installed it and tested this morning it shift’s so quick now in all modes. This was really needed with all the extra torque on e85 great job!”
3. “thanks man , i really like how my car shifts now, im going to put the extra 10% clutch pressure now”
4. “I just installed it today and my car shifts perfect, love this update worth the money”
5. “I tried the car. it’s superb. the gears change really fast and you can really feel the extra pressure on the clutches, I no longer have the problem of gear disengagement at full throttle in launch control.”
6. “I am very impressed. It turned out really good. ”
7. “I installed the EvoScan SST mod, It’s really great. No more gear slipping and hold the gear much more stronger. Really appreciate it man thanks”
