So here is where I will throw up data I have logged through WINALDL both before and after I change the PROM in my ECU from a auto-tranny PROM to a manual tranny PROM. For reference as to WHY I need to do this, refer to this thread http://coloradok5.com/forums/showthread.php?t=188535 So I got my cable in the mail yesterday, spent some time today getting it all hooked up and streaming data to my laptop. So I logged some data as I drove around for 5 minutes. The data is a 73 page text file, so I don't know what you guys are looking for? I guess tell me where to look in the log for the data you guys need to see to help figure out why my truck failed emmisions so bad. TIA!
