What You’ll Notice
- More confident launches — reduced slip, especially in 1st/2nd
- Cleaner upshifts under wide-open throttle and on rolling pulls
- Smoother part-throttle commuting with less hunting
- Stronger midrange because the TCU stops choking engine torque
“Much more torque in 1st and 2nd.” — Customer Feedback
The Process
- Prep: You’ll need a Windows laptop and a stable internet connection. We provide the interface or confirm the one you have.
- Read: We remote in, read your current TCU software, and verify exact variant support.
- Tune: We calibrate shift timing, pressure maps, torque limits, and gear-specific logic for your setup.
- Write: We flash the tuned file and guide the first drive. Most benefits are immediate; adaptation continues as you drive.
- Teach: “Fill in the cells” by running through each gear at different throttle actuations. The TCU will need a bit of time to adjust its torque calculations. This means the tune should gain most effect after 500 miles and full effect after 3000 miles.
“feels lighter and faster.” — Customer Feedback
Technical Highlights
- Raised clutch pressure tables to prevent flare at higher torque
- Optimized shift scheduling for common mods (intakes, downpipes, ECU tunes)
- Tighter torque arbitration between ECU/TCU to reduce “soft” throttle feel
- Per-gear refinements to improve both daily driving and WOT performance
What to Expect After Flash
- Immediate gains in response and shift behavior; full adaptation usually settles in over several hundred miles
- Data-driven support: if needed, we’ll review logs and refine
FAQ
Will this void my warranty?
Any tuning may impact warranty. Many customers choose to flash back to stock prior to dealer visits.
Do I need special tools?
A Windows laptop and a stable internet connection. We guide you remotely and provide the correct interface or confirm yours.
How risky is this?
All tuning has risk, however the process is non-destructive and is not a “hack”. Tuners are working within factory defined areas of calibration. We tune for daily reliability and have tested for over 120,000 miles in house. We do recommend a more aggressive fluid change schedule of 35,000 miles.
How long does it take?
Each remote session itself is typically under 40 minutes; calibration time depends on your variant and mods, but is often at least one business day and at most 5.
