Remap service is available for any 3UZ ECU, as well as 2002+ IS300 ECU, and also any GR and UR and some others. Key improvements:


  • ECU can be modified for m/t => deleted are a/t trouble codes and limp mode with reduced torque
  • Rev limit can be altered for m/t application
  • Zero trouble codes for downstream O2, cat converters, EVAP system
  • Quicker a/t shifts
  • Modified a/t shift points vs speed and accelerator pedal position (that results, in particular, in quicker downshifts). Individually tuned in ECT Normal/Power/Snow modes
  • Improved throttle response, individually tuned in ECT Normal/Power/Snow modes. See stock vs tuned example:   https://www.youtube.com/watch?v=z8Wf8aXbl2M

  • Up to 10% power and torque gain guaranteed for any 3UZ engine (95 or 98 octane)
  • No speed limit, both in normal and Cruise mode
  • Fan engagement temperature can be lowered for engine conversion projects with small engine bay
  • Fan control can support any Mercedes fans (W203,W212,etc) instead of factory Toyota fans
  • Up to 0.3 bar of boost can be supported per request. Higher boost is unsafe for stock internals and is not supported by stock MAF and injectors.
