    Default Negative Learn Value

    Hello, I’m new to the forum and the Terminator. I recently upgraded from the Commander 950 MPFI ECU and like the new system. This system is on a 350 SBC. A few days ago I had a hard start issue which I rectified. Yesterday I started the car and got it to 190°-210°. After monitoring the vitals, I noticed the Learning activated but was at -12 is this normal? I let the car run for about 30 minutes before shutting it down, I was unable to get to 0, also have a issue getting the IAC to 5%ish and I’ve tried taping the port and setting it with no luck. Appreciate the help. John

    The purpose of the Learn Table is not to achieve similar values, high/low values (0% or 100%), or any value in particular. It's simply indicating the amount of tuning applied to the Base Fuel Table. Read this thread (LINK), that's what it's all about.

    Thanks Mr. Cabral for clarifying. Initially, I was under the impression the percentages was a sort of meter.
