Apexi SAFC + N/A engine

[TIMMMAYYY]

HEY!

I've seen all the proven performance that the SAFC gives to turbo cars, but would it be able to give performance like this to N/A cars too?

I've got a Rb30e (R31 engine) with minor mods and there's shitloads of hype about the SAFC but no one has used it on a N/A application???

Is there a reason for this? Any help would be greatly appreciated!

Thanks

Tim

if you have a stock ECU then yes, it will give you an improvement.

What other mods do you have?

[Merli]

Yes, you will get an improvement by cleaning up your air/fuel ratios...

Most cars will have a noticable gain by fittment by an AFC or aftermarket ECU...

[TIMMMAYYY]

ATM i've got extractors, exhaust and a pod filter. I'll advance the timing a fraction when the price of premium isn't so ridiculously high!!!

and yes I run standard ECU. Probably making 95rwkw or so I'd guess. Maybe 90ish. Not positive though.

Also, is the SAFC better than the AFC or do u just pay for cos of the flashy blue screen?

[TIMMMAYYY]

ohhhhh also.

Where in the rev range will the improvements be made? Across the whole range or just up top?? Either way im not fussed, any performance inprovement (in a car that isn't very fast) is a good one!

gains should be made where the air/fuel is too rich.

i dont know much on this, i am doing some looking around cos im interesting in this as well, especially driving around with n/a.

i'd guess that the engines run more rich at around peak torque/power.

improvements should be across the whole range but whether you feel it or not is another thing, but you should get better response after the tune.

SAFC has flashy blue screen can show you information like throttle position, speed etc...I believe they also do peak recalls too?

If you can, go the SAFC....maybe even SAFC-II as that has a bit more features over the SAFC.

check your a/f ratios before u go out and fork out $$ on a s-afc.

I diubt it would be running as rich as turbo skylines do since there isent high pressure air entering the engine needing to be cooler by more fuel.

[Nismodified]

an n/a car relies on revving more so than the gts25t

so i would think it would run fairly rich at top end, not as much as the turbo, but yeh

still, getting the ratios looked at before forking out over 600 bucks for the modual and tuning
