Does anyone know of any software that will listen/talk to the ECU through the serial port of a computer. I can get or make a obd-serial for less than 50 bucks. I used a setup like this on a GM, and it was a really useful tool to tweak the engine. I have searched the forum and gotten no answers. Thanks

Ive seen this one before. I was looking for some more complete software. I used to use carbytes. It seemed to have more readings. anyone know of anyother software that works?
