Has no effect on UK/Euro cars, its only on US cars. Ours already are setup to run on the decent fuel we get over here. |

i noticed this when i was in florida a few years back that you can actually select different octane levels of petrol, i think i was filling up on the cheap 87 stuff seeing as it was only a hire vehicle. does anyone use super unleaded on their car or ultimate or v power. I was just told they were exactly the same as regular pump petrol with a bit of additives and cleaners. can anyone shed any light |

Speaking of this, what octane can you fellows get across the pond. Here in the states, I fill up with super: 93 octane. |

Normal/premium unleaded is 96 ron/octain and super unleaded is from 97 right up to 99/100 ron depending which company you buy it from. |

On my 2.6 a wile ago I found the switch, it looks and operates as the EZL (pull up, turn, push back down) it had on it numbers from 1 to 9 if I remember correctly and I did play with it and on some settings the engine misfires or run pretty badly but eventually I got it right and done this click to enlarge

You can damage your engine if you get the timeing out when messing around with the EZL. It is best left alone. |

It wasn't the EZL, the switch with resistors in it looks like the EZL, it was located somewhere behind the battery. |

In Europe you can get Shell 100 Racing pump fuel . My nearest BP Petrol station sells 102 octane but its £2.47 a litre !!!!!! Only one of five in the country . EEK !! Jeremy Edited by jeremy, Wed Mar 10, 2010 8:36 pm.

Worth noting that the U.S fuel classification isn't exactly the same as our RON. They do have lower octane fuel available for the old-school gas guzzling trucks/V8s etc but also supply higher grade fuel for the more modern stuff. Oh, and a US gallon is a bit smaller than ours. But when I was in Miami late last year it was still around $2.50 a gallon (about 4 litres) Will |

Does the EZL have a setting for Rich's rocket fuel? |

Exactly, the US use MON, we use RON.... I believe that MON is a far more accurate method of specifying octane rating, and in fact, 93MON is the same as 95RON... How does the 76 I saw in Azerbaijan sound? It did smell a bit like paraffin when being burnt |

The title of the thread is "free HP, resistor swap". By turning the ECE nob around all you do is put another resistor on the line therefore different timing resulting in different engine power output, but it cannot be done any more because you just said that is worse than messing around with the EZL. |

Well that's good to know, makes me feel better that I'm not filling my car with crap juice. Using 102 would be awesome, until your engine explodes. Being in the US, I have a US spec 190. I've had the R16 resistor out for about 3 months with no ill effects. The theory is that it'll will advance the timing, giving you more power. I've seen a marginal increase in power, though barely noticeable unless you use the kickdown button with the automatic. I've had better fuel economy with it out too. You're engine temp will go up but not by much. There's a whole controversy as to whether removing it does anything over on the American 190 site. They have a bunch of information on it because most of them are American spec cars. Edited by BabyBenz, Thu Mar 11, 2010 12:35 am.

Papa the one you played with is a fine tuner for the KE. It is wired for a reason,it is to stop knob twiddlers from messing with it. It alters the fueling not the ignition and is a big NO NO unless the whole system has been checked and still needs fine tuning. Serious engine damage can occur because of weak/rich mixtures caused by altering the base/enrichment maps from this knob. |
