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.

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?

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 :O

Get a boost controller before SAFC2.

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

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.

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.

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..

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
