Could I get your opinion on this please Shiv
This is a link from the Shell fuel site in Australia.
http://www.motec.com.au/fueltest/ From reading this test, am I correct in stating:
Does the PROcede automatically tune itself to gain large (say 10%) power / torque increases based on the octane level it is given? Or do we only see around a 1% increase but have the ability to increase torque settings (via the user software) due to the decreased risk of detonation? Note: 98 RON (Australia) = 92 AKI (USA) 100 RON (Australia) = 94 AKI (USA) Cheers, CaptOz (Putting another shrimp on the barbie for Shiv (when V2.03 is released)) |

Captn'Oz,
I've been running the 100RON for a while now, what i notice is better fuel economy; possibly this is because the car is developing more power... not sure. I bumped up my V2 settings last night to 92% and did some runs this morning with no issue. Also had a play with an M5 on the way home this evening which was fun. I am driving up north on Sunday so will take the old road, most likely will bump it up to 94% and see what happens. Rgds, S P.S. was chatting with my lease co today. None of the mods worry them or their insurers (infact they are adding the cost of the proceed, PSS9's, exhaust & wheels to the policy in the event of a total loss). They also invited me to their next track day at Eastern Creek |

I agree that running higher octane will give u better economy. My equivalent of Shell V-power here yields me more mileage than say Shell 98 for that matter and the difference is definitely not negligible.

I am using Shell V-Power 100 ( RON ) as well. The factory ECU adjusts for the higher octane values, not the PROcede. In addition you can bump up the V2 user torque settings, if you like to.
100 octane RON = ~ 95.5 octane AKI. - Eugen |

Shell V-Power Racing (100) should be an equivalent of 96AKI and should be able to handle 100% user settings in V2. Anyway, I like your careful way of rasing the settings, that's how it should look like
+1 on Eugens statement

Captn'Oz,
My boost gauge has a peak setting/alarm at 15psi and it has not triggered on the default or 92% settings. On the w/e I will get a good chance to give it a run but will up the settings to 94%, or maybe more if I get a chance to play with the ECU tomorrow so I can keep the increments to 2% at a time with a day or two between increases. I will have to explain to my 90yr old granny the reason she will be holding a laptop on the way back from Gosford on the w/e. At least she is almost blind so she won't see the speedo . That said 92% seams a little better. Keep in mind I'm after the TQ/HP over the whole rpm range, the wide eyed kick in the butt V1.47 hit was nice but I got over that and want it more drivable; you should take a Subaru GT or WRX for a drive and compare how the boost comes on, it will make you appreciate the 335 with the tune so much more. Rgds, S |

On most cars if you just dump in race gas and make no other changes the car will be slower or the same. As has been shown many times with the 335i the ECU has the nice ability to adapt to the higher octane and change the tune slightly thus give you more power.

I understood that 96 octane AKI ( = 100.5 octane RON ) are good for 100% across the board. However, you will have intake restrictions. Are you sure you want to try this now, short before new and corrected firmware/maps will be released ? Or can you wait a couple of days ...

I know the next map is suppossed to be good but I have no idea what it will do as far as performance goes. Cheers, CaptOz |

Oh and no limp mode (for those that are suffering from it at the moment). WRT greater than 15psi, probably not the wisest, even on 100RON. |
