So finally got me a cable made so I can do some datalogging before I start touching the tuning. I just have a stock 92 suburban with the 299 ecm. I am just wanting to get the feel of tuning before I change things up and actually have to know how to dial that in later. Anyways, I am having some problems. I cant seem to find the txt files from my datalogging and I only get a full reading when I let off the gas. It is pretty rare that the box at the top flashes green with 20+ That is usually only at stoplights. WOT shows nothing which kind of important. It could be my chinese rt232rl module or is this just because of the slower baud rate of the 299 ecm? I would post a pic...but I can't find them files haha.
