You would need a puter to run this system so you could, adjust your fuel input parameters. I have heard that you can get standalone chips that can be preprogrammed with the settings you need, but the thing is you would need a template first to work off.
Unless the person has a program that allows you to virtually make it up, but I would not trust this.
Your cheapest bet would be to get a second hand Unichip or something like it.
The guy is here on the coast in Labrador, seemed like a nice enuff fella, they are still operating so I imagine they are ok...
