ECM 16146299?
 

I was going to get software that I could use on my L03 car and my truck and GMECM didn't list my 92 GM truck. So I pulled ECM to see what it had. If it were the 747 or the one that the 94/95 used. It is a 16146299. What the hell is that? Will the data logging software for the 747 work on this thing? I mean they are both TBI engines. Should I get a 747 and replace the stock unit? Does tunercat have a definition file for such an animal?
