Safc Gain (yes I Searched!)

[trent_tr5]

hey guys/gals,

i have a 33 gtst with 3" catback and pod filter thats about it.

now im looking to add more mods, wat would you suggest?

im thinking an SAFC will i get much gain with these minimal mods?

cheers,

Trent

Get a boost controller before SAFC2.

SAFC2 won't help on a car running stock boost.

I am also looking at using either a SAFC or PFC. Is there really much benefit in going for the PFC for a mildly modified car? My mods will be exhaust, FMIC, 10psi, filter, thats pretty much it. Is it worth going for PFC, or would SAFC be ok.

Sorry to hijack the thread, but it is kind of on the same topic.

Here is a dyno comparison from my R33 GTS25t with exhaust and intake. Only modifications between the two runs is getting rid of the factory dual stage boost control and putting in an R32 wastegate actuator, and tuning the car using an S-AFC2.

Hope this helps

Quinny a safc will help by triming the factory standard rich settings if you still wish to run standard boost. But it will make a bigger difference when you up the boost. Check out the site in my sig mate it should answer most of your questions and the tuning guides are written in the order id suggest to do your mods. Also do a search heaps of info on here too.

cheers

Thanks Munna1, I have had a look at your tuning guides, and my mods are pretty much in line with the Stage 1 guide. I already have exhaust and pod, I will be getting a FMIC and boost controller soon. I will change boost to 10psi, other than that, I don't think I will be doing much more with the car because it starts to get into expensive mods after that. Around 180-200rwkw would be nice. I am just not sure whether it will be worth the extra $500 to get the PFC if the SAFC will do pretty much the same job.

i was in the same position you are, tossing up between safc and pfc. at low mods there is little bo be gained with the pfc, but should you every decide to up the boost, of upgrade the turbo then the pfc will suit much better.

safc = waste of time

I got a powerfc, fmic and exhaust and managed 210rwkw.

Safc would be a dodgey 190rwkw or so

[mad082]

power gain would be dependant on how well the stock ecu is running. if it is running poorly then the power gain would be bigger, but if the stock computer is atually pulling its weight then power gain would be less. i got 204rkw with stock computer and turbo and my afr's were above average for a stock ecu, according to the dyno operator, so my power gain would be less than someone who's afr's were up the creek.

as far as afr's go, performance gains between pfc and safc would be very little, it is just the fact that the pfc can control timing and other things that makes it a better unit.

also if you have an auto then forget a pfc and just get a safc.

id recommend the SAFC II if you dont have enough cash to get a standalone ecu..

here is my last dyno printout when i had my SAFC2 tuned..

rb25det R33

HKS 2530kai turbo

3" Exhaust turbo back (custom twin pipe dump)

Custom exhaust manifold

Electronic boost controller

FMIC

SAFC II

Blitz pod

BOV

an safc2 with the sitc ( ignition timing control ) unit is great for people who dont want to do too much to their cars and is an inexpensive way to control your engine.

Hey guys. I thought i'd give my parts a plug. Currently selling both

a SAFC2 and Super ITC to control timing. Both are in excellent

condition. Please check out the for sale section. Cheers
