Ha everyone,

Just wondering if anybody out there could help me make my mind up on which fuel controller to get at the moment im running about 12 pound boost on a stock rb20det with a k+n flat filter and i think its putting a ridiculous amount of fuel in it and not giving me the power i deserve. I've been looking at the Apexi SAFC2 which looks like a cheap option www.apexi.com i know somebody who has a turbo xs fuel controller that runs off a game boy which is also good and works well and u can select four different maps for that but i dont like how u cant import it that one is on this site www.turboxs.com.au and the mother of all fuel controllers a power fc a 'stand alone' fuel controller i like the idea of not 'piggy backing' the old ecu and starting from scratch but its definitely more expensive. Especially for the rb20det because u need to buy the AP special type power fc which turns out to be about 1100 without the controller.

Yeh so if anybody has any experience with fuel controllers for the rb20det let us know.

Cheers

Sorry for taking so long to reply i thought knowone would reply because i put it in the wrong part of the forum, i think? but i have bought a SAFC (the first one) controller and installed it already into the loom(those wires are tight in there) and mounted it where the ash tray was i didnt mount it in there i mounted it on the outside sort of, hard to explain looks good but. As for the second hand ones coming i guess im abit late keep the other guys updated though. I got mine for 150$ which im happy with off my dads mate from work so very happy. I was just playing with it then and made it about 10 percent leaner on the full scale and noticed the engine ran smoother then i went to about 15 percent on full throttle range and ran smoother but i noticed a loss in power at about 3000 revs so i made it alittle bit richer then adjusted the ones on the side of that to make the graph smooth and gradual, and what a surprise it was smooth as through the whole rev range. It also backfired but dad said that was common after leaning a car and i should be very careful of ping. If anyone knows much about tuning these units anything at all let us know i want to save the money for the dyno run.

nice work Daniel, sounds like your getting your hands dirty and learning a fair bit at the same time.

Id call the guys at Top Racing or even Ken at Hyper Drive if you want the best advice.. but like any good advice be prepared to pay for it.

how will a wolf go on a tiptronic R34...

I hear the R34 shifting logic is separate or someshit and the car is not as smooth when aftermarket management is added..

should i wait for these V4's or just get a safc 2 or a safc neo

Autos 34s can not use aftermarket stand alone ECUs so its E-manage(Fuel and ignition control) Safc(Fuel only but if you need to take much fuel you will have detonation problems with 34s as it also adds timing because its signal bender for the AFM and your telling the ECU you have less load )The best ive used sofar is Haltechs Interceptor with great fuel and ignition control and a boost control output but they cost more than a PFC but theres not much option with R34 Autos.Most shops in town inc us sell and tune any of these units.

how much info do u have on the old school Apex AFC's nib?

i looking at getting one of eBay for about $50 for my excel cause it runs pretty rich

(the old school one dial AFC's, and maybe the S-AFC multi dial ones - if u no what im talking about)

    • I mean it's a bit late to say "This won't have any tangible effect and it is not worth spending more than about three seconds on it, please just enjoy the car" But I said it anyway. Does the pod actually get any airflow in that position behind a bumper like that?
    • Hey guys - apologies for digging this up. Has this website been shutdown or is the outage temporary?
    • So, went shopping at Just Jap for things that might work for the intake  After some trial fitting there I ended up with a 3" x 45° silicone bend, a 3" x 300mm alloy straight, and a humped joiner, some minor trimming will be required to shorten some of the stuff, but nothing that is beyond my "ham fisted" skills The guy at Just Jap was most helpful as we had all sorts of joiners,  bends and stuff out trial fitting  Laying it out above the stuff in there it seems everything will fit nicely, and looking at it, it is probably the way I should have been looking at doing it from the beginning, probably..... In the end it is a front bar off job anyway to remove the original stuff behind the front bar that is taking up the required realestate needed, so maybe a Thursday or Friday job And because I'm a hopeless consumer, I grabbed some new steel wheel nuts, the current ones are a spline drive type with a "security" socket, that somehow someone keeps misplacing, the new ones are a basic black steel 17mm hex socket In other news: I just did my "final" tax return, I am now officially a old retired veteran pensioner, and I'm milking the system for all it's worth,  life is good
    • I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!  
    • Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out
