As one of the leaders in European ECU tuning and calibration, Tuning Tech FS is proud to offer ECU tunes for the Lexus ISF, IS250, IS350, and IS200T. We have created a strong and reliable tuning solution that improves horsepower, torque, and driving characteristics by reprogramming the factory ECU.

Customers are welcome to come in and take advantage of an in-house dyno tune or simply mail in their ECU and allow us to make the necessary changes to make reliable power. Our tune includes changes in fuel tables, ignition timing, camshaft parameters, and more to extract maximum driveability while keeping up with the reliablity of your vehicle. The dyno chart is a comparison between our custom tune before and after dyno tuning. Note: In-house dyno tuning is included wih the price for customers who want to have their vehicle custom tuned in our state of the art, climate controlled dyno facility. At TTFS we have one of the few AWD linked and load bearing dynos on the East Coast. Stop by and check us out.

Shipping costs for sending an ECU to us is the responsibility of the purchaser. The ECU will be tuned within 48 hours of receipt and Tuning Tech FS will then ship it back. The price includes shipping to lower 48 states.

Welcome to Club Lexus!

Do you have any available before-and-after dyno sheets to show the gains provided from the ECU tune for the 2nd Gen IS350 or are you awaiting a test vehicle to verify the tune?

Also, the six-speed auto transmission on the 2nd Gen IS350 is known for being notoriously slow to respond when manually shifting gears as it behaves as a gear limiter rather than a true gear shifter. Would it be possible to improve the responsiveness of the six-speed auto to better emulate the shift speed capabilities as seen on the 4th Gen GS350 with the same (or similar) six-speed auto?

Ditto, for me a transmission "tune" is more important than engine tuning right now.

We are doing a 2007 IS250 AWD stock right now. I will confirm and post results as soon as I have them.

Frank did say he is working on a transmision tune. I will have him chime in when he has a chance to go further in detail on the transmission tune.

28WHP on the F but about 14WHP on the 250... Excited to see what you can do on the 350

Tune for 2012 is250 awd?

Nice gains for the 250! Pretty cool that you can gain that much for the quote un quote slowest Lexus......

Please do one for the 350!! If the results look good and this tune is the real deal and won't reflash itself back to stock then I will 100% buy this tune.

We hope to have a local forum member's IS350 in soon

Yes we can tune that

We kept it safe and reliable since this was a daily driver non enthusiast owned car.

We hope to have a local IS350 in soon.

What would be very interesting is to see what gains you can get on the 16 IS 300 being that it is basically a detuned 350

We have confirmed we can tune it, we are looking forward to getting our hands on one!

Also it seems like you might be the correct folks to talk to about this. Maybe a dumb question. Would it be possible to do a simple ECU swap between the 16 300 and 350?

I have an 07 IS250 AWD. PPE headers, fast flow cats, invidia mid-section borla quad exhaust with ISF rear conversion, F-sport intake. can your tune be fine tune past the point of your stock IS250 awd non enthusiast loaner?

We do not want to get into that yet and have not done any experimenting. Of course if we do any projects like this we will post. It is just too soon for that, we just want to focus on the models the community wants tunes for the most.

If you are asking if we can tune your car more aggressively then the 07 IS250 AWD stock we did above the answer is yes. You have modifications. But what we stress the most is that you be up to date with your maintenance.
