This is Great News...

The only question I have, since every car is different, how is this ONE tune "applicable for ALL ISFs?" Different altitudes, gasoline, barometric pressure, weather, stock vs PPE/Silky Headers, other exhausts, intake...etc...

I have seen this approach from bigger companies and this strategy does not work for all.

I am open to this... and thank you guys for trying this for our cars. Once the ECU is back, do the cars need to be tuned? What about reverting back to stock? Are you replacing the ROM in the ECU or changing the actual parameters in the memory?

Looking forward...

have you heard of the cobb accessport?

I view it as the same way Lexus made one 'tune' for all US ISF, despite different altitudes, gasoline, barometric pressures etc. This 'tune' is just more aggressive. They may eventually have multiple tunes for different mods. Although the factory tune has proven very accepting of exhaust modifications so it also may be unnecessary.

For anyone wondering about the differences between the 2UR-GSE in the IS-F and the RC-F: http://pressroom.lexus.com/releases/...oduct+news.htm

I would also like to know about going back to the stock tune if someone decides they don't like it for whatever reason.

If you make improvements to the tune how will the early adopters be treated with regards to upgrading to the latest version of the tune?

Also is this is a one size fits all tune? or will there be different tunes for different modifications?

After reading the initial post, it sounds like they will not be releasing any software nor hardware (to interface with the ECU) at this time (No DIY). So, to get an update, you'll have to mail it back to them. To go back to stock, you'll also have to mail it back to them.

It is completely revertable, and doesn't involve flashing through obd, and all stock files will be archived for returning to stock. Shows no signs of ever being flashed once reverted. Rafi can have your cars ecu stock and back to you with only one day turnaround.

Obviously different fuel and different mods get different files.
