Guys I just noticed , I am trying to tune a 1227747 using winbin with a simple ecu. After reviewing previous posts folks talk about about a 2nd ve table. The Ecu file I am using has one VE table and the RPM limit is 3200.. WHY ?

Where can I find a a good def file for tuning the ECM.. ?

I new to this game but have been reading for quite some time.
just installed the efi system the vehicle runs great has a few small issues nothing major slight over rich cold start but clears out. also decel surge 45 mph and lower.

Thanks for your help .. oh by the way a had a carb on the 350 prior with 10-12mpg.. after testing and burning a few chips 19 mpg .. wow!!
