Hey
just wanted to see if anyone knew if there was a way to read and/or modify my ECU on my car and change variables of my choosing. I decided since its under warranty, not to change anything on it, except mabe the interior for now,but I wanted to change shift points, and take off the electronic speed limiter. is this possible for my car... 2001 Sonata?

I haven't heard of any ECU mods for the Sonata. Now you could probably get a standalone ECU to help modify your fuel dilivery and things as such. I don't know about anything that helps on getting rid of the speedlimiter (I don't even think the sonata has one of those?) and changes trans shift points.

I know my car is capped at 110 mph, US 50 right near me :??:

Do you know of any handheld tuners that can change anything else for my car at least?
