I have discovered that I have an incomplete .xdf definition file that I am using with TunerPro RT. The file is called DA3, which is the correct one for a 93 LT1, but it does not have nearly all the tables and constants that it should. Also, I contacted TunerCat to see if the definition file they have for sale would work with TunerPro RT, but they say it is not compatible. Does any one here have a DA3 definition file for TunerPro RT that has tables like LOW OCTANE ESC MULTIPLIER vs RPM and LOW OCTANE ESC MULTIPLIER vs MAP?

 

sleeper, I looked at the TunerPro DA3 download bit definitions file and those tables are not in it. Apparently no interest in the older stuff. Have you tried the TunerPro GM Definitions forum, maybe you could get something over there that has something. Otherwise it looks like you will need a hack to add the tables. " http://forum.tunerpro.net/viewforum.php?f=7 " . Another path .. if your sure TunerCat has the tables in their $DA3 you can download the 30 free trial 'Tuner' program and pay the $19.95 for their definition file. If you like TunerCat then it's $69.00 after the 30 days to register it. Assume you already have the EPROM programmer.
