Petrol brand aint so important.. If you are tuned on V power or vortex or 2000 then if you use BP it wont matter, Its pretty obvious BP has hell high quality octane in it as on a stock car it made my engine not burn it correctly and back fire.. If anything u tune on another fuel and then use BP.. It still makes the car feel shit tho.. Its as if it does not burn.

Works fine when the engine is quite warm tho..

Should clarify..

The tune you get on a paritucular fuel gives you, depending on what you ask for: Good KM vrs Fuel consumption or Fuel for Power.. Vortex is actually rated the best Power giving petrol.. But I find it burns very quickly

Safc is included in aftermarket.. Its using fuel/airflow mixtures to get the best power or km depending on your tune... Id say doof has one too.

Good thing about stock ecu.. When you put new fuel in it adjusts for that fuel to try give best mixtures.. But we all know the ecu sux at that. Safc is tuned on a particular fuel its not so much an issue tho.. A standalone tune is actually tuned to prevent knock but give power so its more important.

Just get a knocklite if you run a safc and it will help or dyno it with diff fuels.. lol

See now if you have ever met me and seen my car you would know that I DON'T have an SAFC :)

I don't have shit... I had planned to skip all that and buy a new ECU outright... this plan started at the dawn of Apexi cancelling their PFCs... and then the prices went up...

The SAFC tricks the ECU to change the fuel and airflow mix like Nath said... It won't make a massive massive difference, but it would be best to stick with what it was tuned in, cause it was custom tuned for that type of fuel...

I've come to realise that V Power Racing burns REALLY fast too... I was pretty much at 100kms before this optishit started dropping off full... I'll check when I go home, cause that's pretty nuts...

ahhh crap i have to fill up today im at work atm hopefully they have bp ulitimate or i wont be able to get home :banana: or t least premium.... if worse comes to worse have to use normal unleaded is this very bad?????

Don't use anything less then 95 ron...

Daughterboard hey... sounds intriguing :ermm:

my work has been running out of ultimate on some tanks but not others and we always have premium.. the government took the rebate off petrol which is why its 13c more then regular unleaded not 11c.. I've heard a rumour that BP has been running out because they dont have their own depot (could possibly be only in newcastle) and we share shells depot and they're giving us trouble lol ... I'm not sure if thats 100% why they're running out but its definatly a reason..

I have heaps of skyline owners come in and used regular ethanol unleaded in their cars lol I cringe of course but couldnt be too bad for it in an emergency

I get it all the time at work too, tools going psycho at me for stuff thats completely out of my hands when the suppliers / manufacturers of the product are the ones responsible / at fault.

i just filled up with BP ultimate. every pump was working, and price was 1.45.? which is pretty cheap. also drove past another BP and they had ultimate too.

so whats all the fuss?

yeah thats cheap

i paid 1.51 for mine other day :banana:

yeah paid 151.9 the other day for BP at wetherill.

no v-power for ages at wetherill shell.

not sure if theyve refilled yet or not.

guy at the counter said they're doing some refinery work.

had to pour a lil bit of that crappy ethanol addative petrol from shell :S :S

what's crappy about it?

you get slightly better economy on it, it's 3c per litre cheaper than normal petrol and it has the same octane rating as premium unleaded

so that'll be win/win/win then

    • Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks
    • I thought that might be the case, thats what I'll start saving for. Thanks for the info 
    • Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.
    • Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
    • My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
