Full exhaust with tuned length front pipes, and an ECU with the speed limited and I assume a few other things altered, and that is it power wise.

But your right one tap of the throttle and shes right on boost, I guess it's because I'm still in the early part of the ownership cycle where you notice every little thing about the way your car drives, what the gauges are doing and when etc.

At the moment I have done a mix of highway and stop start driving and I have done ~260K's on half a tank so thats about 12.5L/100K's with normal driving.

I find that not fanging it when cold does wonders for the fuel consumption. Generally I try to avoid giving it to the car when the oil temp gauge is below 70c, that way things are up to operating temp.

You will get poor fuel ecconomy if you use 5th gear at speeds slower than 90km/h, I know some people who use it at 50/60kmh!

Not necessarily - I use 5th gear at 60km/h if I'm holding speed and/or the road is going downhill. The motor isn't labouring at all, in fact it cruises along quite nicely. It's actually pretty surprising how little throttle is needed to hold it at 60 in top gear, unless of course the road rises, in which case you use 4th (or 3rd if it's a hill rather than a rise). Personally, I've found as a general rule of thumb, if I can go another gear higher and not use any more throttle (or even less sometimes, as it doesn't need as many revs) then it'll use less fuel. You can sort of just tell when the engine is happy at a particular rev - do what the car feels like it likes. That's just the way I drive though, it won't work for everyone.

Mine gets given the herbs fairly regularly, and it's very unusual for it not to get at least 450-500km out of a tank, with the majority of that being ligth city driving (driving in the city but not much traffic). Most I've ever got from 65L is around 950km... all highway driving, and it was on the Xmas/NY holiday, on the way to the North Coast, up one of the most ridiculously over-policed highways in the state (Bruce H'way).

hehe that was me who used 5th at 50-60km/h. I stopped doin that now, but still didn't really improve economy. A new 02 sensor and i got about 30km more and still to do a new crank angle sensor. Currently gettin 330-350km from a tank with cat back, bov and filter.....stock boost.

I've been keeping a log recently and have got the following figures:

DATE | PRICE PER LITRE | NO. LITRES | TOTAL $ | DISTANCE | L/100km

22/10/02 | 96.7c/L | 26.75L | $25.87 | 218.3km | 12.254

26/10/02 | 97.7c/L | 47.41L | $46.32 | 384km | 12.346

29/10/02 | 93.7c/L | 47.29L | $44.31 | 395.0km | 11.972

All distances include heavy trafic, while the last entry included the cruise down the wollongong on the 27th.

What sort of figures are people getting with tuned Power FCs under similar conditions? I'm aiming at getting one in december after my final exam ever at uni (if I pass).

I have a air filter, exhaust, razo sticker, and standard boost.

sir ricelot you forgot to tell everyone you get those economy figures on *REGULAR UNLEADED*

*gasp*

i got 400 easily per tank, sometimes 500..........even got 700 once and i drive like a frigging maniac, go the s15s :D (this is on 12psi too)

you perth boys must remember that city driving in perth (or canberra etc) is about the same as highway driving in sydney, the same level of traffic stop start etc.

there is no comparison for peak hour traffic in sydney, unless you're comparing speeds with the push bike weaving thru traffic, in which he eaaaaaaaaaaasily wins........damn onarun and his bike.

  • 2 months later...

can i just add here, yes after 3 months...a powerfc has made no difference to fuel efficiency, however, i do have 500nm of torque over the whole rev range!? :P

for the sake of the original question asked....reset your ecu, try and use the same petrol brand, bp ultimate or whatever and manage your right foot....

    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
    • These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.
    • The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
    • It's amazing how well the works on the leather seats. Looks mint. Looking forward to see how you go with the wheels. They do suit the car! Gutter rash is easy to fix, but I'm curious about getting the colour done.
