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.

      Duncan's V37.......race car?

      By Duncan · Posted

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
