APR reflash to Ron95 map

Pls see below info from Karl, APR Principle

Date: 9 September 2009

Dear Esteemed APR Customer,

Kindly be informed that APR Malaysia is officially issuing a formal request to return for an ECU remap inspection. This is in line of the recent government mandate to petrol vendors on the supply of 95RON octane fuel. The inspection, reburn or upgrade of software is provided FREE OF CHARGE.

Currently we have tested the 95RON octane fuel from a few different petroleum companies with the APR 95RON octane map. The test has conclusively confirmed that the 95RON octane program has matched the fuel octane efficiently and is near perfect to the reference point of the 98RON octane map. During our diagnostic procedures, there were no pre-detonations detected in the engines and there was only a very small power loss (almost unnoticeable) with the 95RON octane map.

Vehicles covered under this recall are:

1. Audi A4 1.8T MY2000-MY2002 B5.5

2. Audi S4 2.7T MY2000-MY2002 B5.5

3. Audi RS4 2.7T MY2000-MY2002 B5.5

4. Audi A4 1.8T MY2004-MY2005 B6

5. Audi A4 1.8T MY2006-MY2008 B7

6. Audi A4 2.0T MY2005-MY2008 B7

7. Audi A6 1.8T MY2004-MY2006 C5

FOR YOUR INFORMATION! ON petrol ...

The Difference between RON92, RON95, RON97 and RON99

Many said that RON92 petrol is the older petrol/gasoline, only suitable for older cars or for cars that uses carburetor only. There is also some that said that RON92 petrol/gasoline will make the engine dirty and also said that RON92 petrol/gasoline is less powerful compared to RON97 and RON99. Before you make any false assumptions, let us see what the real meaning of RON is.

RON stands for Research Octane Number. Octane number or octane rating refers to the petrol/gasoline ability to withstand auto ignition (knocking) inside the engine. Higher octane number refers to higher ability of the petrol/gasoline to fight auto ignition (pre-detonation). In other words, it means that RON95 is harder to ignite compared to RON92.

Different vehicles are designed to be use with different octane number of petrol/gasoline. Higher octane number petrol/gasoline is basically designed for high performance vehicles such as sport vehicle and racing vehicle. Why is that so? This is to avoid premature ignition of petrol/gasoline inside the engine because of auto ignition, which happens before the spark plug ignite the fuel. This phenomenon is known as knocking. Knocking is not wanted because it reduces the performance of vehicle.

The right usage of octane number based on design and adjustment of engine will maximize the performance and effectiveness of the vehicle. Modern vehicles are equipped with knock sensor, which enables it to adjust its combustion timing automatically according to the petrol/gasoline octane number to avoid knocking or premature ignition of petrol/gasoline.

Not all vehicles require high octane number petrol/gasoline. You can check your vehicle fuel requirement inside the guidebook of your vehicle or you can simply check the minimum Octane Rating at the back of the fuel lid cover of your vehicle. Most cars can still use RON92.

Higher RON number does not means that it is more powerful. It means that it is harder to ignite. It will also cost you more.
