I have a is250. I want to do what jaguar did with the XXR. Where the power in the Trans was a 10/90 power ratio. What I want to do is put that in power mode but have it work like the VVT system in that it turns off after 30MPH. and that auto trans with the shift ability is to low so I will set it a lot higher like 3,500RPM or 4,000RPM so I can shift myself with the levers. Won’t happen for a year to a year and a half due to the fact that I’m a freshman in collage in the auto tech program at Kirkwood witch is a T ten school. Toyota school. Will that be possible to do that kind programming of course it will not be the stock ECU and TCM when I get done.

 

Given you can't reprogram the car at all, I'm gonna go with no.

 

As stated above....no can do.

 

Crack the code and let us get it done.

I had a friend that had a programmer come all the way from Japan to reprogram his Subaru GT AWD Turbo. Even with the code crack it took an experience programmer to tune his turbo car to shift correctly with his new turbo and shift points.

 

why dont you wait to finish your freshman year before claiming such a bold project.

 

I think what you want is hondata type of thing. Sadly they only make it for Hondas/Acuras.

 

Hondata will does not adjust shiftpoint on an auto tranny and I know this as I have one running my Integra.

 

the IS AWDs are already a 30/70 ratio.

 

Ok thank. Just was throwing out what I was wanting to do if I could. Well I gauss Hondata should get going on Lexus if they can do that kind of stuff.
