Is anyone running a Apexi SAFC II and having success??? I heard the ECU was learning over the SAFC I!! Anyone have there two cents to pitch in?

 

I am pretty sure there are a number of people running the safc II with only one problem. It will not allow you to add fuel so you will need to bump up your fuel system and then subtract fuel out. Although with the emanage i have been able to both add and subtract fuel without any problems.

 

SAFC is usefull when at wOOt. Otherwise your ECU will adjust everything.

 

So if i purchase a SAFC II and larger injector and tune it. Ive heard you can only subtract fuel!!! Im not going to be disappointed with the ecu readjusting and learning over the tune will i?????

There you go! Have a nice read. Follow Rhyzin's posts, I think he really knows what he is talking about.
You shouldn't need any injectors to make SAFC work. If you really need injectors the best way is Emanage.

 

i have had no problems with my safc2, yet like everyone else, the ecu will learn over all corrections that are not WOT. you are probably better off getting the rrm SplitSecond piggyback or the Emanage (Ultimate, if its out yet). just my thoughts on it, i dont regret getting it, but it would be nice if the corrections would work at lower throttle.

he was the first to do it

 

I know how to hook up the AFC and all but im just really wanting to make sure that our damn ecu wont relearn over the settings. Im not wanting to re-tune it everyday.

 

It's like this,
you can't tune for the time when you cruise around.
The only thing you can do is adjust your AFC and you will only benefit when you will floor the gas pedal.

It's piggyback specific, but some info might be usefull and related to your question.

 

Thanx blaze thats a great link. I have a piggyback from RRM already which is N/A. I took it off when i put my turbo on. Ive played with it when my car was N/A but its such a pain in the butt to tune with. Having to turn off the car everytime and load the changes and try them again. You do this over and over. Real pain. I was just trying to find a simpler tuning tool that you can use that arent such a pain to change settings. But from everything ive heard is that the AFC will only work in open loop. That would kind of be alright but with larger injectors idle would be whacked!

 

eh, if you want a car that runs perfectly, buy something stock

 

Thanks for your help

 

I know with the emanage the ecu will not relearn any adjustments over 30% throttle and/or 3k rpm..

 

i was running dangerously lean with the apexi SAFC II
after AMS tuned it ..they recommended AEM EMS...i was still
pulling 260+WHP and 250+ WTQ but was not a healthy lancer
at that time..
