I've been looking through different threads and saw some people using the AFC II for the SVT but not for the Zetec. I'm not sure if there is a difference, but there shouldn't be.

I ordered the SAFC Neo, and read on different threads that it will work for about a day or so, then the computer will re-program itself back to the origional settings. I don't know why it would because it splices right into the wiring directly in the computer. And if the computer will try to reset itself the SAFC will re-program it again because it's always hooked up to a power supply? Is that right or did I miss something along the way?

I'm not using it for performance, I'm using it for tuning my turbo to make the engine not run too lean.

ok, exactly what are you talking about/ neaver heard safc neo befor. what its it and such, got any links?is this like a programmer or what. being vague with what your talking about wont find many answers.
the only way to tune properly is on a dyno...period.
if this is one of the lame chips that splices into a couple of wires... glad you believe that crap.
spend a crapload on performance parts and trying to cheap out on tuning will get you only one place...starting all over again.
if it has to be spliced in, don't use it.

oh, and theres some big time differences between the svt and regular zetec. svt has different perameters and a few othe things added to the ecu

I dunno if it'll work on the SVT, but my friend had one on his srt-4. if you have a turbo also look into a turbo timer. good luck

Ah yes. My Honda friend has a VAFC (Vtec and Air/Fuel Controller) that splices directly into a few lines going into and out of the ECU. It shouldn't reprogram itself as the whole purpose is to change certain parameters in the ECU. If it's for a normal Zetec it most likely won't work on a SVT or vice versa even though they're technically the same motor. All in all though you're going to need a boost controller if you're going turbo which I believe should be able to handle the same things as the AFC and more, but I'm not sure since I really don't know anything about turbo setups.

i would suggest not using it on the svt since it has variable cam timine. your changing the a/f ratio but doing nothing with the timing which isnt a good thing with boost since too much timing will cause detonation in a boosted engine.
timing needs to be retarded along with a richer a/f mixture.
get your money back and get a real tune. hate when people do this and a few months later are back here whining about trashing their motor...

Get the Innovate Motorsport Lm-1 or PLX Device and have it street tuned

The SAFC Neo has a high and low throttle setting, meaning that if you hammer on the throttle, it will adjust different that if you just drive normal. I got it today from FedEx. I was reading the manual on how to use it, and what wires it hooks up to. It takes the wire that controls the A/F and cuts it and there is two wires on the SAFC and re-wires them. I'm just using it for the turbo until I eventually get a stand alone. I'm going to get a boost controller and guage soon too. The actuator is set to 8.3psi, which should run fine on stock internals. I have another engine in my garage on a stand which I plan to build up the internals and the head.

im pretty sure all safc has a high and low throttle setup
my buddy has a safc 2 on his srt4,and that is what we tuned it with.
apparantly that's a popular mod among SRT-4 owners. I know a couple people that used em.
