I bought a new car.
I changed tires on it and now my spedo is off a bit.
Can someone from Chevy send me the software to reprogram my on-board computer?

I bought a car from a dealer, but he doesn't want to give me the software.

Can anyone help?

Same thing, right? I purchased a vehicle and I want to modify it, I should have access to all of everything that can be used to modify/update it.
