do i need an apexi s-afc???

[PashaK]

first of all, i'd like to say hello to all of you in the forums, the info here is priceless and has helped me at many times.

i have a 1993 r33 gts-t with the following mods:

front mount cooler, 600 by 300 by 76mm

turbosmart type 3 plumback blowoff valve

turbosmart dual stage boost controller

k and n pod filter with cold air intake hose from bumper

thasts about it for performance mods

im currently running just under 10psi and have tried to go more but the engine pings and splutters and it sounds like the engine cuts out for a second or 2.

i called a guy that specializes in turbos who has a dyno and he said a s-afc would fix those problems along with a dyno tune.

what do u guys think??

and whats the difference between the s-afc and the s-afc 2??

thanx in advance

if you're not thinking about anything more like bigger turbo, injectors etc then get the SAFC otherwise go something like a piggy back ecu.

the main attraction of safc2 would be

safc2 has 12 points (compared to 8)

and it also uses factory knock sensor.

yes ed said it well (useless response post).

you should be able to get 170+ rwkw when u put on an S-AFC with that other stuff

i dont plan to upgrade the turbo anytime soon, or the injectors,

i got quoted $600 for an s-afc, and $700 for a s-afc 2. do they both do the same thing, cos if i dont need to spend the extra money then why bother

whats a ruff price for a piggy back ecu???

and what can it do that a s-afc cant???

thanx

[ed]

piggy backs usually can also do ignition timing (ala apexi ITC).

rough price for a piggy back ECU? I'll tell you a rough price if you can tell me how long a piece of string is (get my drift?)

controlling timing can also gain you a bit more power than just fiddling with air/fuel. the prices you got are about right. consider installation and tuning cost too.

[PashaK]

is there any other way to do ignition timing???

cos im pretty sure that ignition timing might be one my problems, i thought that sorta thing can be tuned without anything additional.

one more question, is a piggy back ecu more than a s-afc??

[cereal]

Yeah, an ECU will cost more than a SAFC. One of the most common upgrades is the Apexi Power FC. But there are pleny of different ones out there which all do a great job. You've just gotta find the right one for your needs.....

[turbomad]

Well the SAFC is actually a piggy back system in that you still retain your standard ECU, it only does air/fuel ratio not timing however the timing is fine set at factory setting of 15 deg. I have similar mods to yours and without the SAFC my car carried on a bit as well mainly due to the over rich A/F ratio, but I was still able to run 11psi. I would go the SAFC II as your best off with the latest stuff although there is nothing wrong with the earlier model.

The brand new S-AFC (the one with the knob on the front panel) also allows you to place fuel points at 200rpm intervals instead of the previous 500rpm.
