Thread: EFI Options

Tweet

True Dave.The thing I am talking about is a example of Roger who is trying to get the tune down on his EFI.I am sure his set-up has a o2 sensor and temp sensor. He is still working on his fuel curve and ignition advance.What Roger is doing is not uncommon for the aftermarket systems.
I think one of the key questions I am asking is if there are self learned systems,then why are there tuning opportunities over and above that??.

I think it really depends on whose and which system you use-there are many flavors out there, from the EZ-EFI from FAST (which self tunes and has few parameters) to the FAST XFI, Motec, Big Stuff, Edelbrock and the Holley offerings-

The main reason so many offer the tunability is that not all of them have a self-learn feature, and some fo the few that do leave something to be desired-some have very few parameters that can be adjusted that it's barely above what the Factory offers (which is very little in terms of adjustability for the average user, and, will void the Warranty if performed)-

On top of that, you might want to consider Processor speed (which determines how fast it can "adjust"), and the expandability of those options-right now, Holley has the fastest Processor (for an Aftermarket unit), but that won't last for long-aftermarket EFI is such a growing, evolving and quickly expanding market that I think there will be expansion into OEM types of control (Navigation Systems, "Onstar" types of programs and other features)-I think the sky is the limit, as Traction control, data aquisition, nitrous/boost control and so many more options are already available-

It is certainly an exciting time to be a hotrodder-
