I was going to but now weather is not permitting for me to do it. You are in a nice warm area where you can get the numbers and stuff required for this. Hit up Andy and be the first for the 3GS owners
Someone also needs to figure a way to Dyno this car. I tried and had no luck with everything we tried. On the 2gen GS you have to snip a wire to allow the car to hold gear. That was as far as I got before the weather got really bad here and we have ~3 more months of this snow/cold/ice/ect....

^ we tried that
along with every other mode and even different gears. I was told by the dealer the car has to many sensors and basically the car knows the rears are moving while the fronts arent. Its tripping all the safety stuff. Hopefully someone has better luck then I did.

Hopefully someone has better luck then I did.try a 4WD dyno, maybe you can get the fronts spinning (dont ask me how its probably super hard) and it will forget about the safety stuff. maybe they only need to be spinning even if it is 2 mph.

The 2007 3GS will old gear or at least mine does, I think it is because it has no vdim, not sure!

I was there with passnu2 and his car simply would *not* stay in gear.

As I mentioned in a different thread, I improved a little bit over 0.2 sec. in the 1/8 mile. I haven't had a chance to go to the 1/4 mile track again, but I can see a 0.5s improvement without a problem. I'll post more info whenever I go to the track again.

Same here... for several grand I'd like to see test results from someone first... I realize MHPs guess at results is a highly educated one, but it's still a guess... (especially as different as the transmissions are between the F and ISx50s)
Speaking of... will you be able to make the TCU act like the IS-F in that it actually shifts and holds gears, or will "sport" mode still just be a top gear limiter?
Happy to volunteer if you need a mechanically stock IS350 test mule... there's a number of local dynos and an 1/8th mile track fairly close (and a 1/4 mile track a bit less close).
