went to the track and it sucked!

[Justicc86]

yester day I went to the local drag strip and ran my car for the first time with the fmic, safc2, boost controller (14psi) and my car ran the same as it did on stock boost and smic that time is : 14.62@ 98mph wtf ?

also I have not changed any settings on the safc2 Is this the problem?

any help will be great!

[Hijacker]

the fuel map should be fine for a setting of 14. what about tires? crappy tires won't grip well and give crappy times

[Onizuka]

no LSD, worn tires and improper fuel tuning would be my guesses.

I bet it mostly has to do with you SAFC though, you might be running really rich.

[PacManVR4]

Decent trap, drive a little better. What did you run before?

[Cyberkreig]

I dont know anything about AFC's other than i dont like them.

[Hijacker]

^ :Werd

[Nathan]

What was your 60ft? that trap speed says you should have gone faster. You were granny shifting weren't you

[Hijacker]

he forgot to double clutch it :lol:

[Nathan]

I was wondering if anyone would catch that reference

[Hijacker]

i've been quoting that movie way too much tonight. i need to lay off the starburst

[SRdave240]

I dont know anything about AFC's other than i dont like them.

and that sir makes you a moron.

[PacManVR4]

I would hate to have a hard tuned ECU. Fuel computers and standalones are gods gift to tuning. F the one size fits all stuff. If you hate an AFC, you dont know anything about them.

[Cyberkreig]

and that sir makes you a moron.

I'm not going to resort to personal insults, I'm not a troll.

SAFC's are BAD news. It is a band-aid cure, for a serious problem. Tuning of fuel and igniton should not be guess-work. I despise people that claim 30++hp from plugging one of these into their stock car. And i dont have any love for people that try to tune modified motors with something like this and complain about rich/lean conditions. GET a wide band (or dyno time) and something with a 16x16 map. Like emanage or standalone if you have the money.

[SRdave240]

Sorry if I was a little harsh. but like you said yourself - you don';t know anything about them!! Sure, you won't get 30whp out of a stock car just by plugging one in. But it is a great inexpensive tool that lets me correct my A/F's run larger injectors and run a z32 MAF. At the same time, it provides a super accurate tach, a knock sensor read out, a MAF sensor voltage read out, and looks really pretty sitting on my dash (LOL). Am I claiming it is as good a tuning tool as a stand alone? Hell No! I will get a Power FC eventually. But it is not a band aid cure.

You need to educate yourself before you go bashing products.

[Cyberkreig]

Then i'm sorry but we are going to have to disagree. I DO feel that it is a bandaid cure. It does do all the things you just listed but it doesnt accurately tune the fuel curve. It does, in my experience, give the owner a sense of security. I have yet to meet anyone with a moderately modified motor (upgraded injectors/turbo) tuned by SAFC that was running correctly (not rich/lean)

[SRdave240]

OK, we can disagree. Maybe your friends just don't know how to use it correctly (although it's not that difficult).

Would it make you feel better if I posted my A/F ratios before and after tuning with my S-AFC II? Granted I don't have a turbo upgrade or larger injectors but I fixed a WAY lean condition - went from about 18:1 down to 12.5:1.

[Cyberkreig]

Actualy its pretty likely that the people i've met dont know how to use it. LoL. Maybe thats part of my soured outlook.

I'm not saying it doesnt have A use, I just dont think it should be relied on solely. With A/F ratios like that it sounds like you had some sort of wideband tuning. (the right thing to do vs. Autometer bouncy-light)

[ItzGenX]

LOL! Thread highjackers!

[Cyberkreig]

yeah just a bit.. but he did ask about his SAFC settings =P

[SRdave240]

Yeah, I used the WBO2 - not much point in dyno"tuning" without one. On the stret, I keep things in check with a Greddy EGT - narrowband A/F gauges are pretty worthless IMO.

I will agree with you on the point that if you are going for a turbo upgrade with 300+whp, just a fuel controller is not the best option.

[Tweaky_Tom]

What he said!

[ride4lame]

uh back to the original topic, what was the 60' time?

[GTS4-R]

Knock sensor read-out? are we sure about this one....as far as I know the only FMU units that can be used to read knock would be the Stand-alone units.....I've NEVER heard of a piggy-back reading knock......

[Nathan]

The new S-AFCII's do have a knock readout.

[SRdave240]

Yes, it is basically a numerical display of your factory knock sensor reading.

It is nice to know it's there. It actually came in handy in letting me know not to use 91 octane. The knock was inaudible to me but I caught it with the readout.

[Justicc86]

Well for the folks using a safc2, what is a good base setting to start from. Do I need to start leaning it out or add fuel?

and the 60ft is 2.2 on street tires not my best but I figured it is good enough. and the times im running the same times that I did when I was running stock boost and the side mount intercooler.

[stumpz]

hrmm, sounds interesting, i am not yet sure, i recently installed my afc2, but i'm not very familiar w/ all of it's features as of right now. i've ran into some other complications. so..

[Cyberkreig]

See SRdave, THIS is what I was trying to say!

Justicc -- So you saying that you installed FMIC, SAFC and raised boost and you are still running the same times as before? You are also saying that you just plugged in the SAFC and didnt tune it in anyway? Without at least an EGT gage I'd venture a guess that the AFC isnt doing you any good!! This is not guess work, and each motor is different no one can just GIVE you a base setting.

Here is my best advice to you: 1.) Rich means slow & cold, Lean means Fast & Hot. You probably need to lean the car out but without the help of widebando2 or EGT you run the serious risk of damaging or destroying your motor. I would like to see what the car runs with the SAFC unplugged.

[ItzGenX]

Justic, I just noticed you are from Hattis.

Anyway, my motor did 14.1@98 at stock boost. Where are your shift points? When I upped the boost to 12.5psi it ran 13.8@101. This is with no AFC or anything just a boost controller. This is with 93 octane and nasty richness (cool fireballs when I go down the track sometimes).
