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)

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 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.

5. Transmission shift points optimization. (Optional)

6. Optimization of the protection mechanism (knock sensor) and speed limit.

7. Optimization of VVT-i engagement.

These are actual results from my testing.


All pulls were made on 93 oct

Modifications
OEM & Stage 1- K&N drop in filter.
Stage 2- HPS intake tube w K&N drop in filter and TTI sports catalyst down pipe.

If the crank numbers are dead on, there is over 18% drivetrain loss. And the tuned numbers put it right around 267 bhp.

This is what I was looking forward to with the 200t. Even thought about replacing my IS350 just because of the possible tuning capabilities. I emailed Cobb about tuning but they have no plans as of right now.

Considering they bumped it by 3 psi and only gained 20 rwhp, it's disappointing. I've seen better gains from naturally aspirated engines that switched from an 87 to a 91/93 octane tune. I honestly expected more from a boosted setup. Hopefully it's something simple that's limiting it, but you may find that this platform just won't perform well.

Actually that's not bad for 3psi on a small turbo, On VW's you get a 20-30hp by bumping up 5+ psi.. I'm sure with an intake and downpipe upgrade you will be able to free up another 30whp.

This is a very good news!
Soon with small upgrades the 200t can go head to head with the 350.
The 200t will probably need intake, exhaust, hot pipe replacement + fmic , cold spark plugs and a good tune. This list should give 60-80 whp depending on tune and if the engine can handle the extra boost.

You guys must not know much about BMS! I've been trolling the BMW forums and they are able to tune the horrid BMW ECU's with their piggy back with great success. It's only a matter of time before they crack the IS200's ECU and get a solid tune for us.

And with All the extra money you just spent, you could've just upgraded to the 350 for less.
