Lexus ECU Tune

*Note, due to toyota hardware based reflashing protection, some RC and IS ECUs are required to be data-dumped manually for the initial tune build.
What this means is that there is a possibility your ECU would need to be shipped to us for an initial data dump. Every instance afterwards, the ECU can be flashed through the OBDII port and never has to be removed from the Vehicle again.
If this is the case, We offer 1 day turn around and overnight Shipment return (48 state USA) for minimal vehicle down time.
What Goes into this tune? What is adjusted?
- Ignition Timing
- Variable Valve timing
- Fueling and Fuel compensations
- Transmission shift maps and shift calculations
- Throttle mapping adjustments
- Torque demand and limitations and more
What are the expected gains?
- You can expect on a 100% stock vehicle with 91 octane
- 18-26 Horsepower / 24-30 ft lbs (higher with 93 is possible)
- 3IS Sport + Tune: Enhanced Throttle mapping per gear, adjustment to high load ignition timing in Sport +,
- 3IS Transmission Shift: Altered Trans torque Shift Output for upshifting. Alters shift engagement and transmission shift speed during high load upshifting, no momentary power drop during shifting. *noticably harsher shift engagement*
Please Note: This package requires sending us the Vehicles ECM.
- We offer a 1 day return option
- Turn around time from when we get the ECM is 1 day
