SO it seems I am messing with one of the rarer ECM's. I have been trying to get my friends suburban up and running and really want to see the data that the computer is using. I made a cable to use with Winaldl, but I don't have a pin E in the aldl port, so no 160 baud. So I made a cable for the 8192 baud (The two transistor version, used with a serial usb adapter) But there is no free software that I can seem to find that will give me any live data.

OK, no problem I will be happy to purchase Tunerpro RT. Hear good things about the program and $40 is cheap for good software, but I can't seem to find anywhere that says it will read my ECM. I don't mind spending the money, but I can't afford to throw it away either...

Long story short, does anyone know if Tunerpro RT will read the 6299 ECM? the truck is a 92 suburban 1500 4x4 with a 350.

Thank you
