My check engine light came on while i was f'ing with the SAFC-II. i had it installed and tuned, so i have no idea how to tune with the thing. I was trying to get it back to the readout screen and got all mixed up in the sensor selection screen. Is it possible to set the check engine light off by messing with the SAFC and if so, what are my options to get the light off until i can bring it back to the shop.

 

i wouldnt full w/ it unless you know what your doin, my car was messed up, cuz someone fulled w/ my settings. as long as your car is running ok, leave until u can have the code checked.

 

first off. Yuo should pull your code and see what it is. Autozone you can borrow a coder reader for free. Anyway here's your setting should read Karman, and also 4 cyn with the arrow from lower left pointing to upper right.

 

Yes, if you change the air setting to something other than Karman, it will set off a code. It is not good to drive with it like this, nor to continue doing so with the SES light on. Your first mistake was getting an S-AFC without knowing how to tune it yourself while relying on someone else to tune it. People like this are supposed to get flashes, since those are "set it and forget it." The next mistake was messing with it without knowing how to use it, although it's incredibly simple if you just do a little reading on here in the S-AFC forum.

Do this:

1) Go to the Tech Guide at Evotuners.net and read the S-AFC setup or go to VFAQ.com to find it, too. Follow the setup guide to make sure all of your settings are proper.

2) After this is done, disconnect your negative battery terminal for 10 minutes, then reconnect it. The SES light should go off and not come back on. Put the key in the "ON" position before cranking it up. If the SES light doesn't come on, then crank it up and drive it around.

3) After all is well, consider getting a flash and selling the S-AFC.

 

So, according to you, I was supposed to get a flash because I purchased an SAFC II without knowing how to tune it.

I say keep the SAFC and learn to tune it or get it tuned by someone who knows how to tune properly.

 

Thanks Warrtalon. I agree, i wish i had the time to learn how to do this. I'm sure after i fix this, i'll be motivated to learn it.

 

I think warrtalon was tryin to help him there, and you give him smack.

 

I didn't give him smack. I just didn't agree with the one statement.

 

No, gonzo, not at all. Not knowing how to use it upon purchase, but with the intent of learning how to tune it yourself is one thing. Purchasing it with the intent of having someone else tune it is another thing. The former is wonderful; the latter is a bad decision.

I have a lot of buddies locally who all had flashes, but who saw what I was doing with the S-AFC and decided to buy S-AFC IIs to use on TOP of their flashes. Each of them I have helped with learning how to tune, but I'm proud to say that each of them bought their OWN pocketlogger with the intent of learning how to tune without relying on me to tune their S-AFC's for them. If YellowEvo is willing to learn how to use/tune his S-AFC, then he will be much better off than he was before. If he doesn't have the time nor desire to learn, then he'd be better off with a flash.

 

Problem fixed, and i upped the boost for good measure.

 

I just dont think there is anything wrong with having someone tune it and then learning afterwards. That's all.

 

Again, I'm talking about NOT HAVING ANY INTENT AT LEARNING HOW TO USE/TUNE IT. This is not a hard concept to grasp. The whole time I was talking about people who buy it, have it tuned, and then never touch it themselves. I've seen people like this at the track who had Buschur Stage 1-4. I'd go up to them and be like, "Hey, man, nice Evo...whatcha got? Oh, I see you have an S-AFC II. What settings are you running?" The answer is usually, "Uh, erm, I have Buschur Stage 4, but I'm not sure what's in the S-AFC. They just sent it to me like that." I proceed to show them how to get to the "settings" screen to see how much fuel is being removed at each rpm, then put it back in monitor mode. That's what I'm talking about...

 

I know what your talking about. Understand what I'm talking about.
This is not a hard concept to grasp.

 

But what you're talking about is not important. I made a comment and you disagreed. I have since qualified my statement so that you understand it, yet you continued to disagree by ignoring the details of my comment. I obviously understand what you're talking about, because I've already said I agree with what you're talking about. The problem is that what you're talking has nothing to do with my original comment and therefore is not relevant.

 

i just got my. learning how to set it right too. i would say buy it and learn it rahter learn it without one sitting in your car.
