*********really? I cant imagine you did a search and asked that question. I know three cars in the search below that are specificly automatic************

Does anyone know if the computer will adjust for the change in tire size and yield no result, or will it be beneficial? And I am well aware she is not a Porsche, but I still enjoy throwing her around the curves. But don't sell the Taurus line too short, let's remember the SHO and what car is it the police are starting to go to again?.....
(note: the police are drriving dodge chargers)

Am well aware of the sho.
I am also aware of the difference between the two.
Kinda like the difference between a V6 mustang and a shelby.

So you have changed out all the suspension parts, and added all the engine parts......right?
1. Both of the cars I have documented are auto transmissions.
2. You need to check a taurus form to see if the Tranny ECU adjusts.
I know that on the infiniti products the tranny will 'learn' how you drive and adjust accrodingly. (as discussed at length in my posts) But it cant tell if the tires are different sizes. IMHO no car can. But if your corning style is reflective of your driving style, then you have 'trained' the tranny ecu to shift for speed and not for eco. You would need to unhook the battery for an hour and then it would reset and start to learn again.
3. seriously, if you arent running 40 or 45s AND you really are 'cornering hard'....well stay off my streets. you are flexing the sidewalls.
4. you remind me of the guys looking to do 2 inch dual exhuasts. Large exhausts only work at wot. WOT only happens 2% of your life. unless you race an oval track, you are only turning 10% of the time. And how much of that can you race thru the curves???
5. The only draw back to taller tires id the speedo is off. But if you are running a scangauge (which you should) then you can correct the speed on the scangauge.

here are the multiple results from searching 'taller tires'
taller tires - Google Search
