I know I'm looking for something that probably doesn't exist.. a PC based programmer. I know most of you might say I'm looking for tuning software, but I'm not. That is too in-depth and expensive. I'm wanting software that is as easy to use as most hand-held programmers, but without the hand-held part. I can't help but think I could save some money if I didn't have to pay for the hardware. I have a USB/OBDII cable, so if I could just payfor and download the software it would make things cheaper and easier. Any help or direction would be appreciated!
