i learned a lot of FI, on turbo cars, before owning a Ltr. One of the cheapest ways to modify the fuel was a S-AFC (air/fuel controller) it allowed you to adjust fuel to air per 100 rpm, but then you could get into stand alones and adjust any thing you want, fuel, spark etc.. for those that dont know. I think I understand what all the pims/commanders are doing, opening up or useing the factor installed fuel maps or the manufactors maps(correct?). What i dont understand is why they only choose to follow what is givin in the factory computer. Don't get me wrong, these machines are extremely crazy and fast with these fuel maps but with the ability to adjust accordly to what the machine needs w/o become rich would give you more power than just dumping fuel, thats in a turbo thou, i don't know if this applies to a n/a motor. I know some you have a few chooses from but not like a real stand alone. A standalone would be mean undescribable potential with just minimal modification.
I try to find as much modifications i can online but i'm probably not looking in the right places, has someone found a stand alone? i know the price would drastically increase over the yosh and dyna but it would be well worth it because that allows you to run the most power,reliably and thats what we all want... a fast machine that will last.
