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

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
