TTI Motorsport ECU re-flash for 3IS 8AR-FTS Stage 2 released
2017 LEXUS IS200T Stage 1 and Stage 2 ECU upgrade
TTI Motorsports has performed long-term testing on the 8ARFTS engine, and with our accumulated experiences and resources the Stage 1 and Stage 2 formal testing phase has been completed.
The 2017 IS200T computer upgrades was optimized to make the following (The following are the actual wheel horsepower values on the dyno)
Stock : 179.9whp / 250Nm (184 ft-lb)
Stage 1: 208.5whp / 277Nm (204 ft-lb) (+ 28.6whp / +27Nm (+19 ft-lb)
Stage 2: 223.7whp / 291Nm (214 ft-lb) (compared to stock numbers + 43.8whp /+ 41Nm (+30 ft-lb) (Note Stage 2 testing was done with the addition of SPOWER down pipe and TTI intake)
The following engine optimization content has been performed :
A modest increase in turbo pressure value + 0.2- 0.3 bar (3-4 PSI) from the factory computer setting, in addition to the following parameters:
1. Increased throttle response.
2. Air-fuel ratio optimization. (safe and durable supply curve)
3. More precise ignition timing. (for stricter monitoring of detonation)
4. Adjustment of the water-cooled intercooler pump actuation time for increased cooling effectiveness.
5. Transmission shift points optimization. (Optional)
6. Optimization of the protection mechanism (knock sensor) and speed limit.
7. Optimization VVT-i
