It's been like 2 - 3 weeks now with no Ultimate. I've had to use some Synergy 98 & Optimax.

I want Ultimate again! Anybody who always uses ultimate but is having to use another fuel feeling the difference? speak up.

I think Optimax has been slower, 3rd gear 12psi just isn't pulling as quick I think.

I have been using vortex98 for the last few tanks and fuel economy is exactly the same.

The car does pull harder in 2nd and 3rd!!

I was suprised but my car runs better on vortex98 than ultimate or optimax.

I'm of the understanding that most of the east coast has got an Ultimate shortage, with stocks to be restored at the end of December or early January.

I've been giving Synergy 8000 a go, I'm on my 3rd or 4th tank, I've noticed that power seems to be ever so slightly up, though my fuel economy has dropped slightly.

yep, there's been none in my town for at least 3 weeks (2 BP's, both out).

is really beggining to sh*t me cos i gotta drive 15 mins down the road to get optimax, or remember to fill up when im passing a shell/mobil out of town.

tried vortex and wasn't real keen, my knock levels went higher than i've ever seen them (although was a warmish day and car is tuned for ultimate).

Well ive been running on synergy 8000 and recently swapped to optimax extreme.. and as far as im concerned it kills bp ultimate. I've got noticable power differences, specially after re-setting the ecu.

Though will good to be back to ultimate again, no ethanol or anything to worry about:)

i think the "Ultimate" part in BP ultimate's name has a lot of people fooled lol

I think you'll find most workshops agree you can tune the hardest on Ultimate for any pump 98 fuel in Aust.

#1 Ultimate

#2 Synergy 8000

#3 Optimax

Some people say Synergy is a tad better than Ultimate but usually Ultimate is the prefered fuel for tuners trying to get the most outa it. I got the most power & lowest knock out of my car tuned on Ultimate.

how do you go about resetting the ECU?

Disconnect the battery, press the brake pedal to drain all the remaining power. Maybe leave it for a while then just hook the battery back up.

And I've been using Optimax since they went out of Ultimate and to be honest there is no difference at all imo. :(

i ran my car on ultimate all the time and i found it pulled harder, had better economy and ran better, less lumpy in the idle. Using vortex and sh*t like that made my car crap, noticed it clutch kicking at pt.g last week.

GO BP ULTIMATE!!!!!!!! please come back to me

Sounds like you guys over east are just getting what we went through over here about a month ago. The refinery had a problem so they couldn't produce anything but normal unleaded, so most stations were without 98 for a few weeks. Over east was still ok because they stockpile it I guess. Now that it's normal over here, that was probably the priority so all the fuel has probably came to us. :)

It won't be too long I imagine. Unless there are BP refinery's over east, I would think there would be which would mean I'm babbling shit.

You lot are complaining but over here Ultimate is the only 98 fuel we can get so it hurt us a LOT more!!!

Ultimate is more expensive than extreme 100 here in QLD... On any given day BP is at least 2 cents dearer than shell at aspley and virgina....

So i stopped going to get fuel from BP along time ago...

I had the fc tuned on optimax and found extreme to knock a bit more but the extra 50km;s per tank has not rally made me a fan... ill stick to 98 plus i get 4c off a litre at shell also...

So thats a saving of about 3 bucks a tank... I also get a 600ml coke when i fill so thats a free coke in my books....

50-60 litres of fuel for the car and 600ml of coke for me....

    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
