Running WinALDL on a 91 GMC 5.7 (1227747 ARJT) When I try to datalog the box at the top will flash different numbers with a green background and also some with a red background. I read a thread that said a red background indicated a problem. If so how do I determine the problem? Also is it best to datalod in raw data or what?
Thanks for all the information that I have aquired from reading the posts here.

Any ideas?

 

Well I kept searching and finally found some info. Got rid of the red light by changing the buad rate to 4800. It looks like everything is working now.
