SAFC or powerfc?

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...

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

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?

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.

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

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

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.

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?

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:

      Rusty roof repair

      By MBS206 · Posted

      Hot tip, stop picking at shit. Live in bliss instead   From my recent experience in rust repairs, white it may seem to not go much further back, you'll still need to cut back a bit further.  From what I can see there, the outer skin, and the inner is rusted too. From what I can see you've got the inner one which is all structural, and window likely affixes too.   If tag Murray Calavera here, but my phone won't let me tag him, he'd probably be able to give the best advise.   I do know, welding roof panels is a right pain in the bollocks! Very heavy to heat distort the roof and warp it all.

      Some of the filler.   Also if I look under the top flap of metal it starts looking good quite close to the edge. I get the feeling it doesn't go much further.

      Rusty roof repair

      By PranK · Posted

      So, I finally started digging at the bit of my roof that was cracking and bulging a bit. Well, it was just thick filler that was covering some pretty bad rust. I didn't find the edges, I was too bummed to keep going.  There are a few holes as you can see. There was just so much filler but looks like no attempt under the filler to prime or use rust converter, just slapped filler on exposed rust.  Anyway, I'm going to take the windshield out and find the edges. I'd love to fix this myself as I'm pretty sure it'll be expensive to get done properly. I was thinking I could just get a cut piece from another E39 and just weld it in place as it would be the right size and shape.  Thoughts?

      This is the territory of the "Stage 1/2/3 Golf GTI/R" or otherwise off the shelf tune with (relative to before) minor mods. It's easier now. Downpipe and Tune and boom, big increases. Stage 1 OEM+ is where it's at. This is where the niche evolved into and it's really easy to see why. It's rare to even NEED to consider changing turbos or going to aftermarket ECU's or building bottom ends for more power. Stage 1-2-3 will get you a LONG WAY. Civic Type R turbo GR Yaris/Corolla Anything with B58 (MKV Supra/x40i) Anything BMW in General Anything Audi in General Any turbo AMG RenaultSport Turbo offerings Korean Elantra N/I30N Ecoboost Mustangs Focus RS? List goes on. I would argue in the future it won't even need to go on... M3P is pretty rapid out of the box...

      There is a way, but it's not with the same cars. You need to find the same vintage of car, that we had. Realistically, that was an affordable car with aftermarket parts around. So what people need to find is a car that had a decent base in its day, and can be modified. They're looking for a car year make of 2010 to 2015 really... Aus could have done it if Holden didn't fold as V8 commodores were cheap, and if Ford didn't get expensive thanks to COVID, then you could cheaply play with FG Barras. Realistically, those are just a bit heavier, four door skylines. I'm sure the US and UK have similar cars they could find.
