Well this is my new baby, and hopefully is arriving today, (THANKS Onpol <img src=icon_smile_big.gif border=0 align=middle>)...

and just for background, I'll include what it's meant to do from APEXI directly:
<BLOCKQUOTE id=quote>quote:<hr height=1 noshade id=quote>Modifies air-flow meter signal (pressure signal in some vehicles) to optimize fuel-air ratio; Vacuum Fluorescent Display (VFD).
The second-generation S-AFC is a fuel computer that adjusts fuel/air ratio by modifying the air-flow meter/MAP sensor signal. The S-AFC features a user-definable, eight-point, adjustable fuel curve that can be set in 500 RPM increments. The range of fuel adjustment is +/- 50% at each of the user-defined setting points. On hot-wire vehicles, the Deceleration Air Flow Correction function is capable of curing the erratic idle and stall problems associated with open-atmosphere blow-off valves on hot-wire air-flow meter systems. The S-AFC is capable of monitoring and replaying the following data channels in Numerical, Analog Meter and Graph displays: Intake Manifold Vacuum/Boost Pressure, Air Flow Capacity, Intake Manifold Pressure, Karmann Frequency, Engine RPM, Throttle Position, and Air Flow Correction %. <hr height=1 noshade id=quote></BLOCKQUOTE id=quote>

MY QUESTION TO YOU GUYS IS:???

what am I looking at as far as WHP GAIN, after I have it tuned properly??? as you know I'm running rich at the moment, since I have fully installed my I/H/E set-up and I really really need to fix it, lol...

The dyno tuning will run me $150.00 bux, but they claim that they can just install it, and do a basic set-up at the same time of install with no charge, so I ask you, what is a basic set-up??? from reading other posts, I think this is just turn the POWER on and watch the gauges... lol I have also purchased my A/F Phantom Gauge and I'll let you know how nice that looks, since I'm painting my gauge pod to match my dash... <img src=icon_smile_big.gif border=0 align=middle>

Well this means PHASE II of my tibby is almost complete, and PHASE III will begine withing 6 months... wwwwooooooohhhhooooo, just for your info, I will do the dyno tuning no matter what, but I would still like to know what I can expect, 1-2 whp??? or much much more??? <img src=icon_smile_clown.gif border=0 align=middle>

Bat, I am planning to do the same mods as you with the only difference that I am getting SR 4-1 headers and a big bore throttle body. My question is, is it very important to get the S-AFC or can I live with out it for awhile?

i would have to say it's very important, I'm running very rich now, and you will prolly be a little more than me, since you're gonna have your TB and going with 4-1 headers...

BlueSpanishShark · 07-21-2001, 01:08 PM

Am going to buy my stuff before winter starts and I should have everything before winter ends.
Is there anything else I'll need or is the
S-AFC good for what am getting.

Bat your not running as rich as I am lol. I need a Safc but it will conflict with the nitrous so I'll have to see.

I thought Cheuk on FX said that they shouldn't compete for fuel, if tuned right. When I was consiering NO2, I had this same fear. He didn't elaborate, though, so I'm not sure . . .

Bat,
Any news on the tuning? How'd it go and what were the HP gains?

The Safc and zex shouldn't but it's to tune it right.
