Tire Size Extreme
I want to know if the chips programming can be manipulated to the point that the tire and gearing will make a 100 mph speedo work up to 160?
Wait do not flame me. My idea is this...
Create a new speedo overlay that will increment up to 160 mph.
Then change the chip so that the former 50MPH is now really adjusted to equal 80MPH. Meaning that you would really have to be driving 80 to get it to make it half way through the speedo range because of chip math (tire and gearing adjustments).
What do you think Mike?

Hi E.,
That's a great idea, certainly not one to be flamed. I wish it were that simple, many of us would like to have 140-160 mph speedos!
It's not like you can just go into the powertrain program and make it say 50 when it's doing 80, it doesn't work like that at all. You're talking about skewing the entire relationship that the system, including the dash display is calibrated for, and while anything can ge done given enough time, money and R&D, it's not going to be easy.
You would be better of scrapping the entire factory dash display and going with a custom aftermarket custom replacement gauge panel, display & gauges, so you would have a speedo capable of registering speeds way over 100 mph, etc. as well as other additional functions, like giving you 0-60 & 1/4 mile times, there are custom digital speedos will do that. That would be far easier, actually, as that could be done right now with some expenditure.
Thanks for your post!
