Hey just wondering, i know the ADM magnas dont have a knock sensor, but the ADM second gen magnas exported to NZ had them fitted, stated in the owners manual that it put out 121kw on 91ron and 124kw on 95ron, my JDM diamante has one, could these be fitted to your cars or is the ecu not compatable?

the 380 has them too. but the 3rd gen ECU doesnt support knock sensor.
perhaps i could get it to work in my pro sequential ECU

The AUDM ECUs don't have the knock sensor support, but the ECUs in the Aus built USDM Diamantes do. I've looked at the maps from a USDM Diamante ECU and the high octane ignition map is generally not much more aggressive than the AUDM 91 octane map... and the fuel map is even richer than the AUDM fuel map :nuts:

I think that the knock sensor on the export models is mainly there to protect the engine from inconsistent fuel octane throughout overseas markets (read: mega crap fuel) that would detonate the engine to death if the knock sensor wasn't there to pull the ignition back. (Read that somewhere long ago.)

Aussie fuel is pretty shit by anyones standards, hence why the 3rd gen was so leniantly tuned to compensate for crap fuel

Lowest throughout the world is 80 RON, highest is 100 RON.


The selection of octane ratings available at the pump can vary greatly from region to region.
Australia: "regular" unleaded fuel is 91 RON, "premium" unleaded with 95 RON is widely available, and 98 RON fuel is also reasonably common.
Bahrain: 90 and 95 (RON).
China: 93 and 97 (RON) are commonly offered.
Egypt: 80 RON is commonly used for all taxis and old cars and is the predominant rating in rural areas. 90 RON and 92 RON are available at almost all gas stations.
Finland: 95 and 98 (RON).
Germany: "Super E10" 95 RON and "Super Plus E5" 98 RON.
Hong Kong: only 98 RON and 99 RON are available in the market.
India: India's Ordinary And Premium Petrols are of 89–91 RON.
Indonesia: Indonesia's "Premium" petrol rated at 88 RON and being subsidized it cost only about US$0.50/liter.
Ireland: 95 RON "unleaded" is the only petrol type available through stations.
Italy: 95 RON, 98 RON, 100 RON
Israel: 95 RON & 98 RON
Malaysia: the "regular" unleaded fuel is 95 RON, "premium" fuel is rated at 97 RON
New Zealand: 91 RON "Regular" and 95 RON "Premium" are both widely available.
Russia and CIS countries: 80 RON (76 MON) is the minimum available, the standard is 92 RON and 95 RON. 98 RON is available on some stations but it's usually quite expensive compared to the lower octane rating fuels.
Saudi Arabia: Two types of fuel are available at all gas stations in Saudi Arabia. "Premium 91" (RON 91) where the pumps are coloured green, and "Super Premium 95" (RON 95) where the pumps are coloured red. While gas stations in Saudi Arabia are privatized, the prices are regulated by the authorities and have a fixed at S.A.R. 0.45 (U.S. $0.12) and S.A.R. 0.60 (U.S. $0.16) per litre respectively. Prior to 2006, only Super Premium RON 95 was available and the pumps weren't coloured in any specific order. The public didn't know what Octane rating was, therefore big educating campaigns were spread, telling the people to use the "red gas" only for high end cars, and save money on using the "green gas" for regular cars and trucks.
Spain: 95 RON "Euro" is sold in every station with 98 RON "Super" being offered in most stations. Many stations around cities and highways offer other high-octane "premium" brands.
Sri Lanka: In Ceypetco filling stations, 90 RON is the regular petrol and 95 RON is called 'Super Petrol', which comes at a premium price. In LIOC filling stations, 90 RON remains as regular petrol and 92 RON is available as 'Premium Petrol'. The cost of premium petrol is lower than the cost of super petrol.
Taiwan: 92 RON, 95 RON and 98 RON are widely available at gas stations in Taiwan.
United Kingdom: 'regular' petrol has an octane rating of 95 RON, with 97 RON fuel being widely available as the Super Unleaded.
United States: in the US octane rating is displayed in AKI. In the Rocky Mountain (high elevation) states, 85 AKI (90 RON) is the minimum octane, and 91 AKI (95 RON) is the maximum octane available in fuel[citation needed]. The reason for this is that in higher-elevation areas, a typical naturally-aspirated engine draws in less air mass per cycle because of the reduced density of the atmosphere. This directly translates to less fuel and reduced absolute compression in the cylinder, therefore deterring knock. It is safe to fill a carbureted car that normally takes 87 AKI fuel at sea level with 85 AKI fuel in the mountains, but at sea level the fuel may cause damage to the engine. A disadvantage to this strategy is that most turbocharged vehicles are unable to produce full power, even when using the "premium" 91 AKI fuel. In some east coast states, up to 94 AKI (98 RON) is available.[23] In Colorado as well as parts of the Midwest (primarily Minnesota, Iowa, Illinois and Missouri) ethanol-based E-85 fuel with 105 AKI is available.[24] Often, filling stations near US racing tracks will offer higher octane levels such as 100 AKI[citation needed]. California fuel stations will offer 87, 89, and 91 AKI (91, 93 and 95 RON) octane fuels, and at some stations, 100 AKI or higher octane, sold as racing fuel.
Vietnam: 92 is in every gas station and 95 is in the urban areas.

werent we supposed to be getting 100 RON in Oz ? and removing Bio Diesel cos it failed emissions standards?

we get 91ron and 95 everywhere in nz, bp does 91ron and 98 everywhere, no 95 at all. Gull does e10 98ron

I posted that to show petrol octane varies around the world, and that we are quite well off in Auz for octane.

Imagine putting 80 octane in a third Gen though? :-)

If the US Diamante's come with a knock sensor does anyone know if the 3rd gen NZ Diamante's do?

Depends on model, the direct AUDM exports did not, the JDM exports did.

Does anyone know if there are any difference between the NZ & Aussie models (TL)

Apart from the name, no
