Copy settings from one chip to another/ comparison

[TurboSmart]

Well guys, in my quest to diagnose a overly rich mixture I came across a chip that I found on my car thats says race only.
I swapped my extender with this one and idle, mixture, etc worked perfectly.
Now, is there a way to access this chip config, either via ecm or a epprom reader?
Also, will like to check my externer chip also and compare them.

Thanks

If you have a prom reader and software it can be done. I have both.

But adjust the settings ( octane) as well?

The two chips can be compared but keep in mind the Extender chip was designed to work with the MAF Translator. The "race" chip probably wasn't. The Extender has a user option for Open Loop idle, the race chip probably not. O/L idle will definitely be rich. Make sure this option is NOT turned on in the Extender. You'll need a scan tool to see the BLM values which represent the user settings.

There is no setting for octane in these chips, only spark advance tables. The chips intended for higher octane have more spark advance.
