LEXUS IS200t Stage 1 and Stage 2 ECU upgrade
TTI Motorsports has performed long-term testing on the 8AR-FTS engine, and with our accumulated experiences and resources the Stage 1 and Stage 2 formal testing phase has been completed.
The IS200t computer upgrade was optimized to make the following (The following are the actual wheel horsepower values on the dyno)
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 filter)
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.
awesome! is that available to the public yet? did they post final numbers on it? It looks like this is another sensor modulating device that changes voltages to "tune" the car am i correct?not claiming to know anything just kinda following the threads, I know burger is top notch.

No set time frame on the release, but yes it is a piggyback system that intercepts at the MAP and boost sensors giving a +4 PSI increase over stock . These were the numbers from their testing.
awesome results! nice power under the curve, I am a bit surprised the max hp remained the same but the power under the curve there is what is going to change how the car feels! Full bolt ons could net 300wtq, that would be awesome!

Yea definitely! I came to realization that when they say +3PSI its not in addition to max PSI figures but throughout the powerband so thats why peak numbers didn't change much. I guarantee with the addition of a downpipe with a free flowing cat you will see those peak numbers raise.
My Toms Power Box is for sale, i don't have need for 2 tunes so please PM me if anyone is interested.
