SAFC or powerfc?

[JaFF]

I have recently installed a FMIC and since doing so my standard ecu has been maxed out. I get boost cut(?) at about 4500-6000rpm in every gear. I was wondering what i should go for. I know the powerfc is obviously better, but i probably wont do much more to my car. I was only aiming for about 200rwkw and i doubt i will ever change the turbo. I just want to run the stock at about 12psi.

Will the SAFCII solve my current problems? If anything else was to be upgraded it would probably just be a fuel pump or something small so it's not like i have big plans for the car. Just want a nice cruiser.

anyway so far i've only got a 3" exhaust, FMIC and turbosmart boost controller.

The SAFC11 will solve your probs if you get a boost cut defender as well. My suggestion if you want to make 200wrkw is to add up the cost of a boost cut defender and the SAFC11. Then look at the prices of the uni chips and other piggy backs. If the prices are close then go for the later as the UNI chip does ignition as well...

e-manage

hmmm SAFC only does fueling control and is a piggy back.

the powerFC is a standalone ECU, if you can afford it then of course go a standalone ECU.

Otherwise for a piggyback, e-manage is more bang for your buck than SAFC.

[JaFF]

the e-manage huh? i havn't really seen much about it. I think i remember a thread a while ago? will do a search.

haha 1st thread. thought i'd seen it somewhere!

It's a sticky in the forced induction section

What you're experiencing is more than likely a misfire due to overfueling and subsequently your timing being retarded... not boost cut. If it feels fine after 6000rpm, then it's not boost cut.

if you don't want to spend much money, then go SAFC. If you dont mind spening $600b- $1000 extra (for the difference in the cost of the unit + tuning), then go the PFC. For the cost of the e-manage + ignition loom + tuning (which I think is more expensive as most tuners are more proficient with PFC which keeps costs down a little), you might as well go for the PFC.....

I got 200rwkw with a SAFCII + front mount + 3" turbo back + 9psi, I dont see why you cant hit that figure with 12psi + SAFC + good tuning

Nothing wrong with the SAFC, i have the first version and check out my rwkw's and 1/4 times that im getting out of it.

[Zahos]

how much of a difference would you say the exhaust cam gear made Robo?

Not just in terms of rwkw, but in terms of tuning?

what made you decide to get it?

e-manage

you love this e-manage don't ya. You Dan of all people should be using a powerfc for that 'timebomb' of yours, you really need to keep a close eye on that fuel AND timing.

Hey what can i say...any ECU that lets me piss around with it at home has major novelty value for me

Leave my timebomb out of it...it's almost ready for some *real* tuning LOL

Maybe 5-8 rwkw, not too much, i didnt find heaps of difference but every little bit helps now when searching for every little kw.

finally, someone who isnt sensitive to some shit stirring! But i do really like the idea of being able to work with it yourself so easily and alot to be learnt about tuning right there i think.

[JaFF]

mm thanks. Am leaning towards a SAFCII. Are they easy to tune? my mech. has never used one before I don't think, but he's done Wolf ECUs before. He should be able to work it out you think?

I cant find a price for purchase, fitment and tune of the e-manage. Anyone care to devulge this info?

[666DAN]

www.mohdparts.com for all your e-manage needs....as for fitting if you're confident with a soldering iron, it's easy as!

[JaFF]

seems a fair bit more expensive than a safc doesn't it?

you could almost get a powerfc for those prices?

[666DAN]

Comparing to the SAFC isn't really fair....the SAFC can't do a fraction of what the e-manage can. The main thing to remember is people with Autos can't use the PFC.

And with the e-manage you get laptop software that a 2 year old could use, PFC isn't so simple and is time consuming especially if people are using the hand controller to tune.

You've really got to look at what your end use will be, I don't think the SAFC really has the tuning resolution required for any decent engine upgrades....E-manage allows injector upgrades/ AFM upgrades etc etc.

I'd go a PFC if you have a manual, and access to a decent tuner.

I wouldn't say a fraction...

E-manage is better than SAFC, but for what this guy wants ~200rwkw, I wouldn't bother, as you can easily achieve this with a SAFC.

the e-manage in terms of tuning has a better resolution for fuel mapping, and allows you to re-map (or alter) ignition maps with the ignition harness.

SAFC also allows you use Z32 AFM as well.

The resolution on the SAFCII is pretty good.. I got my A/F ratios to a flat 12:1 (with the exceptio of 1 tiny dip where it goes to 11.5:1).

So yes, e-manage is better, but for the goals we are talking about here, the price, effort for tuning, and cost of tuning mean the SAFCII would be a better option.

I agree, on a manual Skylines I don't quite understand where the Emanage fits in. An SAFC is $400 and facilitates control over a/f ratios pretty well with a bolt on turbo. A PFC is $1.1K and enables control over fuel and ignition and a number of other parameters and easily handles a large range of mods.

If I add up how much an Emanage (fuel and ignition) costs including fitting (PFC's just plug in) don't I end up spending more than a PFC? :headspin:

[R31Nismoid]

PowerFC for the $1100 they are ATM are a steal.

And give you options later if you come by cash (1-2years) and wanna do turbo's etc
