#1644, "New Fuel Controller (XFC - Xtended Fuel Controller)" Nov-21-05 07:34 PM by Livid
I don't know if anybody on here has heard about this yet. My mechanic just told me about it after going to a convention in Vegas. It's a new fuel controller aimed specifically at tuning our N/T Cars.
It seems pretty promising. Tech's please examine some of the specifications and let us know your thoughts on it.
Product Description:
The average street car tuner today faces a dilemma. What do you do when you add a stroker kit, supercharger or turbocharger to a modern streetcar? You want to keep all of the amenities offered by the car and you expect performance at least as good as the stock systems. What do you do with electronic throttle? How do you tune it? Solutions do exist but they are incomplete, erratic, require disabling of critical vehicle functions or cost far too much. The XFC is the solution. Designed for the modified street car, a properly tuned XFC can deliver the added fuel required by your high performance parts while keeping your stock powertrain management systems functioning as if no changes had occurred. Competing units offer MAF skew or O2 skew but have severe limitations. Many new vehicles learn to eliminate the changes caused by MAF skew devices through O2 feedback. Competing O2 skew systems cause the vehicle to enter open loop but can often cause vehicles to trigger trouble codes and enter a debilitating limp or failsafe mode. Fuel pump control systems exist but operate on insufficient information. Fuel pump control based on too little information forms a dangerous situation in which a vehicle can be easily provided with far too much or too little fuel based on dynamic weather, battery and fuel delivery system conditions.

Spiffy...but for that price it better be. In all honesty that thing would be of some help...but with no way of controlling injector pulse width you're just banging your head against the wall...just like with any other piggy back system. I would say it's certainly better than the likes of the safc. But is it any better that e-manage? Probably not...except for the fact that it would probably be cheaper. The "future" timing control is slightly intriguing, but the chance of our car being supported would be next to 0%. And the dual wideband input is interesting. But keep in mind we would not be able to use some of the inputs...i.e. MAF and fuel pump control. For our car....we really don't have to disable anything like that advertisement suggests...we fool the MAP sensor into not "seeing" positive manifold pressure. We do disable the FPR, but we replace it with a superior unit.
IMO the best bang for the buck for us is the megasquirt...and may always be...for a few hundred bucks you can have full control of your engine. The only reason I went with an EIC system is because I didn't have confidence in my tuning abilities. Good find though and it may work for some ppl and their individual goals.
