Does anyone know if there is a company that makes a chip for our cars that runs on 100 octane? I know that APR makes a chip for Audi S4's that gives you the choice to switch through three different modes, including a third mode for running only 100 octane gas. Is there anything like this out there for our cars? Are there any companies that could custom make something like this? Thanks in advance:thumbup:

you can put that ocatane in no problem...many people have its just the $$$ it costs for it...

 

[rkaufman]

I know I can put it in, I do it all the time. I just want a chip that takes full advantage of that much octane.

 

[BGReddy00]

o-never heard of anything like that...how much does your gas cost to fillup im paying like 30 for 93!

 

[isaacly]

dang 100 octane

dang 100 octane

The reason they make a chip like that for the S4 is because they run turbos. When you increase the “boost” there’s a greater chance of detonation. Being that BMWs are naturally aspirated they don’t this risk, but it is beneficial to run 100 octane for optimal performance, it'sjust not nice to your pocket book.

It runs me around 60 or 70 bucks to fill up. It sucks, but it makes the engine sound meatier and more powerful. I hate running regular premium in it. It just suffers from comparison.

I dont see any 100 in the CA Bay Area

Those i see with the highest octane number is 91?
it costs about 2.1 bucks per gallon
oh man..

Are there any High octance places like that on the East coast?

 

[Dukes]

BAVARIAN323i, yeah man. Try any Sonoco. Also if you can't find a local place you can always try a concentrated octane booster at an automotive store.

I've never seen one. Only at race tracks....hahaha.....

The best I've found is that 94 oct at Sunoco

I can't believe how much some of you guys have to pay for gas right now. $2.10 for premium? Holy sh*t. We're paying about $1.80 for the same sh*t and I thought that was expensive:sad:

 

[rkaufman]

You guys that are having trouble finding it need to check 76.com. You can type in your area code, and it will tell you which local stations carry it.

Many of the chips available for older model BMW's that run 87 octane modify the spark advance so that it can take advantage of 91 octane. The chips we have in our E46's are tuned by BMW to take full advantage of 95 octane (however, the computer will automatically detune the software if it figures out you aren't using 95). I don't know of any chips that take advantage of 100 octane. But, you can mix 100 octane with 91 octane to get 95. I do that when I go to the track.

:yikes: Damn that's a lot.

Maybe I'm missing something here, but what's the point of putting in higher octane gas than your car needs? That won't help performance.

DAMN! $1.60/ gallon here for premium

just a note on the 'octane boosters available. whe nthey say they raise the octane by 3-5 points they are reffering to the number after the point. i.e.. 92 octane would be 92.5 octane, so as you can see it is not worth the money however mixing in the 100 will do more for you, or run it strait, but the DME will only be able to get so much out of 100. I think on most NA motors anything past 98 is lost money.

What's the point of putting in any sort of higher octane than your car needs?
