Ok, got it. Except for the chip reader and writer. What exactly do I need to do that?

I would love to be able to tune this. Buying a chip for several hundred dollars that might work ok, and would need changed (and bought!) yet again if I change something on the engine, never seemed like a good process to me.

Is it worth getting into whatever the setup is that programs to the computer in real time, whatever that's called??

Thanks for your info and patience with me. Outside of EFI, it's usually me that does the helping in various forums!
