Hi Guys,
Does anyone know of a program that will allow me to convert the hexdecimal software in a ECU software reload in to a graphical 3d map and also allow me to modify the map??
Tuner Cats will work fine. You'll need to make a cable; but, everyone has schematics for most popular vehicles. I made some using the MAX232 chip from Maxim. It connects to the GM ALDL pre 95 stuff.
