Im about to run a e30 mix of e85 and 98ron but i read that australian fuels specifically 98ron doesnt contain ethanol so on the calculator when it says pump ethanol percentage do i just put 0 or is this statement even true? And if it is true i assume i dont need to test any 98ron pumps.

I think it's the same. It all comes from the same shithole refinieries in SE Asia.

94 RON E10 beats the E10 we get out here, which starts at 87 AKI/~91 RON and goes up to all of 91 AKI/~95 RON. E0 doesn't even exist at most servos and when it does it's usually appallingly expensive and no more than 88-90 AKI. 

Lucky for that, because putting ethanol in fuel only lowers the bulk cost of fuel if it's in 91 ;)

Add it to 98, 85% of it even and it quintuples in price. Strange physics.
f**k you United, Gouging c***ts.

That's the thing, they still add it and it makes fuel cheaper, implying adding 10% of it drops the cost of 91 by what, 5c a liter?

I remember when it was barely half the price of 98. Because you know, 85% of what is in the fuel is way cheaper than 91 fuel is by volume.

Actually, ethanol has probably never been cheaper, on a tax free basis, than petrol.

With fuel excise being what it is, and only being levied on the hydocarbon component, not the ethanol component, and ethanol for non-drinking purposes not being subject to liquor excise - E85 was cheaper, but not because the combustible liquid itself was particularly cheaper.

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
