Is it possible to have the software upgraded in a 2007 IS350 so the paddle shifters will operate when the transmission is in D as is possible on the 2009 models?

 

What the bajeebies? Probably has to do with the ecu. Its not that hard to shift it into S mode and shift. Haven't heard them come up with anything or an update to do that.

 

I'm sure there's no official way to add this to a pre-09 model.

There might be a way to physically swap one or more ECUs to enable it (kinda like how you can enable the "real" TC/VSC disable on 06 models if you swap out the trac ECU) but like that mod I suspect it'd be stupid-expensive to do it for relatively little benefit given they're not even real shifters in the first place.

 

actually i asked dealer to update the transmission system if they can, so that I can down shift in D with paddle like 09-10 IS models but mechanics said it uses totally different system and they can't just upgrade the software.

but I still think, it is possible........

 

I wish they came out with a valve body upgrade like the is300 guys have...

 

If there's a software upgrade that could be made, I think there needs one to be one to get rid of the shift delay.

 

I Agree, and instant shift would do wonders on this car like the F. Too bad thewre not really shifters...just gear limiters

 

i am hoping someone would come up with something to make those shifters real shifters!

 

I didn't know that you could do that in D in the 09 10 models ima try tonight

 

Youve been missing out on the fun! FYI, after playing with the manual shift, Hold the Right shifter for 2 seconds to cancel manual shift and it will return to "D" mode.

 

Wow thanks i didnt know that. One time i went into manual mode when id ownshifted in drive and i didnt know the -F to get back into drive mode. I ended up driving all the way home in s mode lol.
