Alright, I am not really interested in doing any serious tuning on this little turd ('91 S10 LN8 2.5 5 speed), but I gotta keep it running until I'm ready to swap engines. It recently developed some drivability problems that I believe to be MAP sensor related and I want to hook up the laptop and look at the data stream to diagnose the issue. I already had some bin files and definitions for Tunerpro because I had removed and disabled the EGR system a few years ago. I have been running the stock memcal for a long time now since it rarely set EGR codes so it has been a couple years since I even opened up a bin and looked at it.
Anyway, to cut to the chase, I have opened several bins and used several xdf's downloaded from here as well as using TPv4 to view them and all look the same. A lot of the values look really odd such as the timing reference angle being 89.75 degrees and the timing values in the main spark map go up near 60 degrees. I don't recall the values being so wacky a few years back when I disabled the EGR and made a few tweaks to some of the tables, but a lot of time has passed since then and I do not have a copy of the modified bin now. I did notice that if you use the graph view function when looking at the fuel and spark tables the graphs look typical if you ignore the numeric values. I'm just curious as to why the values look so odd so that I can interpret what I am seeing. I'll attach a bin and xdf that I downloaded and can verify that other bins and xdf's look the same. Thanks in advance,
Phil
