Safc Ii

[dead32]

hey guys just wondering on your opinions for the best thing to do bout my car, i have light mods so far and i reccently bought gtr injectors + resistor pack to suit my rb20 r32, i was thinkin of installin a pfc + retune but due to the overall cost of such an excersize, i was after your opinion on runnin just a fuel controller to run the injectors and manage the airflow, my question is, how good will it run? i realise its not gona be as good as a pfc but for the price/hp gain, would it make it better on fuel? more power etc etc. honest opinions please as im not very knowledgeable on such a subject.. thanks

covered in the power fc faq, see my signature for the URL

a remap is probably the cheaper option and will give you 80% of what you need

[paulr33]

here are your options

1) buy ap engineering PFC

$1400 + $400 tuned

- expensive ap engineering version

- option of power fc pro for same price

- can be tuned / fixed by anyone who supports PFC

2) buy rb25 or rb26 PFC

$950 + $400 tuned

- rb25 version should throw errors for VCT sensor/trigger

- rb26 version can support twin afms if u want later on

- will need rb26 injectors for rb26 version

- may not work correctly if done wrong

- can be tuned / fixed by anyone who supports PFC

3) buy a remap for stock ecu

$450 ish tuned

- cheapest first off

- will be $450 to have it fixed or "tuned" again if you change stuff later

- locked into only people who can remapping

4) safc II

$400 to buy it (ish)

$250 maybe to tune it?

- cheaper again

- has limited load points and tuning capability

- wont support bigger injectors

- will push the stock ecu too far in the end, the more u lean out or bend the afm signal, the more timing it throws in, so youll eventually be stuck, but it will be fine for stock turbo

- cool display screen

they all should make the same power and performance

the main quality will be how good the tune thats put on the stock remap or PFC. if the PFC tune isnt that good drive to another PFC tuner and get them to touch it up, or use the PFC FAQ and do some of it yourself. you also get a lot more visiblity with the PFC over the stock remap. you get knock sensor notification, afm support, injector support, airflow warning, injector warning, sensor display, 02 sensor feedback and hand controller (also option of pro version if ap engineering). if the remap tune sucks u have to goto the same person or only a few select remappers and they will just charge u the same price most likely to touch it up each time, as they just burn the chip again. PFC touchups should be much cheaper and quicker

i would suggest powerfc as your best option (rb25det but do some research on what you have to do to get it to work).

unless you live somewhere where there is a good remap tuner (hard to find)

think of it as a long-term solution, do you ever think you'll buy an aftermarket turbo? how much power will you eventually be aiming for? if your answer is "yes" and "more than 160-170kw" then a proper tune is a must....

I have a safc II and I recommend saving the money and getting a powerfc

[paulr33]

i guess it also comes down to who tunes it and how good they are

if its just some kid with an eprom burner who dumps a map on and off you go its not going to be as good as a well done PFC tune. by "good" or "well done" i mean the number of load points adjustmeted on the piggyback or remap or PFC tune. the more points adjusted the better the car will be to drive. a stock PFC on stock maps is good but an safc with all the load points tuned will be better. likewise with a PFC with say 30 to 40 points adjusted it will be ace to drive around and have much better response, and probably average power. likewise with the remap, if its got a big wad of ign and inj points adjusted it would be better

[MerlinTheHapyPig]

the number of load points adjusted isn't a very good indication of the quality of the tune.

the quality of the tune would be a function of...

1. the comprehensiveness of the tune (relates to number of map points adjusted, and also relates to the time spent tuning under different conditions)

2. the tuner's skill

3. the features of the ECU

i'm going to avoid talking about remaps v powerfc because it's been done to death and we won't reach a meaningful conclusion

but i will say this:

If tuner skill is equal, a fuel only computer will give you a much poorer tune than a fuel and timing computer (or remapping fuel and timing maps). Tuning a fuel only computer is very very easy, if you have the right tools, it's a simple logical process with little-no guesswork.

1 and 2 are the most important factors, and provided an aftermarket ecu gives you a reasonable level of adjustment they all have the potential to provide equally good tunes. Remaps and most of the aftermarket fuel and timing computers people are using all offer similar features and level's of adjustment.
