Hi all, was wondering if someone could help me out. I'm a DIY'er and recently purchased EFI Live V4 Pro. I own a 1990 ZR-1. I have bought the correct ALDL cable and installed all the software and drivers properly. I can't seem to get the 2 talking to each other. I have tried several different vehicle files, my COM and port #'s are the same, Max echo 232 is off and EFI support suggested changing the T6 value to 10ms, which I did with no success. I followed the ALDL troubleshooting guide which says to use the hyper terminal program (which isn't on Windows7 had to copy it from XP) and connect the cable, laptop, and car together, and if you see code displayed in the program, you know the cable is working properly. I did that and saw the code streaming. So I know the cable is fine. Depending on what vechicle file is loaded, I get different errors when in the Macro tab. It's either "expecting frame header byte", "reply frame checksum failure", or "data frame truncated (followed by a long line code)". I believe EFI Live V4 pro should be able display the dashboard, data log, etc.., but I believe some values need to be changed or I need a different vehicle file in order to do so. I have no programming background, and limited computer saavy, lol. And besides my limited knowledge, I don't want to play around changing things, then end up frying my ECU (they're not made anymore, very hard to find, and very, very expensive). Any help is great appreciated, as I'm at my wit's end trying to get this to work.
Thanks, Joe
