Mate i use to think the same mate

but the truth is that your use to the feel of bp ultimate and also your a bit paranoid

but yeah try another tank and let us know

actually, Im reading the data straight off my PFC. and Im on another Tank of Ultimate. Same deal. But your right, about me being paranoid :)

if ur reading straight of the pfc...f**k u might right then

now you got me paranoid

I USE ULTIMATE MAINLY SOME TIMES VPOWER

I WONT ADD OCTAINE BOOSTER IT MAKES YOUR PLUGS HEAPS ORANGE AND DIRTY.

Yea Ive noticed this about the Octane Booster, But the plugs still seem to work fine for me, Im using Iridiums. Gapped to .8

Apparently also the Octane Booster makes your cat colapse? is this true? either way, it really does help take knock levels down, so i just keep using it. Cats are much cheaper than a engine rebuild I reckons.. :) But Im probably being paranoid again.. Can anyone substantiate if the Octane booster really does make ur cat colapse?

I agree, i race go-karts with 125cc Rotax single cylinder water cooled engine and believe me you can notice the performance drop with only one cylinder. Kart goes well on Ultimate, it absoltely screams on Vortex.

this is just me, but i am solely using caltex 98ron. and it just pulls and pulls. shell and bp are good too, but me and my mates reckon caltex is the bomb. we wud go VPR, but not keen on ethonol :S

different states have different fuels... My project with a worked NA carby 4banger likes mobil, hates shell, didnt mind BP i think caltex was okay.

My Rb25det gets BP coz its close to home, but gets better economy on mobil.

My gf's 7MGE gets best economy on Mobil, but gets the BP aswell...

does anyone have any info on which servos use which suppliers?

im using bp ultimate with no issues here in sa, now adding octane booster too! and my car has just been tuned to go with this little "jungle mix" im putting in my car.

That's a bad idea really.

For a start octane booster does horrible things to the inside of your engine leaving orange deposits all throughout.

Secondly, what happens when you're out of octane boost and your servo has none? Or what if you want to actually drive the car away from the city one day. Most country towns have 92 unleaded only.

Could just be the hotter weather lately, mine has started ping again getting into summer. Go for a run at night I bet the knock levels will be back down again.

ALSO IMO: I think that BP is SHIT. I'm a serial Mobile 8000 guy I haven't ever had a problem with running there 98. The difference when I change to BP in those desperate times were I really need some fuel, my car runs shit. Once I go back to the 8000 or V-power the difference is VERY noticeable. If VPR was widely available and could afford it, I would always run my car on it.

Yep used to run bp ultimate... noticed that it was running like crap compared to what it used to.... car was tuned on BP too......

switched to vortex 98..... much happier....... also Mobil 8000 on par with the Vortex ... currently getting it tuned on Vortex 98 after the last round of mods......

oh Haltech E11v2 ecu and 11ty boltons.... GT35R, ext gate, greddy plenum, wideband O2 etc etc etc etc

have to agree bp has never floated my rb... vortex has always been better but that may be due to the more regular use ie.. people buy crap loads of caltex due to the 4c per litre deal... not that it makes much lof a difference.. but a free litre never hurt.

have trialed many fuels in my area.. ie sydney. I have never used a non name branded fuel.. ie independant.. after a 1 of use in the local leb run cheapo lieing twat.

anyways;... mobil 8000 is usually ok, not pinging on my mods + boost + ign but bp ultime has alwasy been sub par and some shell stations vpower also fairly sub par with savage ignition problems...

That's a bad idea really.

the beauty of having a next door neighbour who is my mechanic, and being able to get the JB products for pretty much what he pays therefore able to buy in bulk and leave one in the car :P

i dun see whats so bad about ultimate.. i use it. always have

mods r remap ecu, unknown turbos, 15psi, exhaust n pair of dirty hks filters... never pings or knocks or anything and made a decent 287awkw... :P i havent as yet tried other fuels.. so maybe one day i will and do some dyno testing. :\

who knows.. ulti might be the worst.. might be the best :P

    • 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.
