I'm sure a math wizard will be along shortly.

I hope so, I was thinking it was 26!/(26 - 2)! * 50 which comes to 32,500

So there's 32,500 possible combinations of initials and states so . . .
the chance of 2 not matching is 32499/32500 or 0.99996923076923076923076923076923
So the chance of a pair is 3.0769230769230769230769230769231e-5

That's where I get stuck. I'm not sure how to figure how many people it would take to get a better than 50/50 chance of a match.

Hey you guys are giving a reformed biologist a headache!

The factorial is only needed for non-repeating combinations. Pretty sure anyway.

Regarding repeats: A better than 50/50 chance that a subsequent combination would match with a previous combination is reached after the 16,900th iteration.

I've been using the ICE Air for a month now and have set it to the -10 setting (did not even try the -20 setting). Coming from a BoosterPlug which is hard-set at -20, I find the -10 setting to be slightly smoother than the -20 of the BP. I don't see myself even trying out the -30 setting.

I really can't tell the difference if there's a change in the way the torque (curve) behaves. But the transient fueling issues are still there though I did not expect them to go away with only the ICE Air (gotta wait for the ICE Cool for this). Not sure it matters but the ambient temps I've been riding in are at an average of 27 deg C. I am trying to get myself used to and satisfied with the -10 setting in anticipation of the forthcoming ICE Cool, which only works in the -10 setting.

Good product. Works as advertised. Kudos to Poolside and company!

I also have a BP on my '07GSA and yes it is working [smoother throttle, no popping when on compression braking] and yes I do expect the ICE Air to take it to the next level of giving me more slow speed throttle control and a cooler running engine if it is running richer [hope ECU doesn't just advance spark in response to richer mixture..since I ride off road over heating is an issue at walking speeds or on long uphill pulls at slow speeds in 100 degree days. In general rich is cooler.]..

Then the 'Cool' will complete the transformation that BMW should have engineered into the bike in the first place..

My question is where did you get the "BP is a hard set -20"? Just curious.

Thanks...

Well thank you, OCJ.

Hey, are you saying you don't want to try the -20 setting? You don't give up anything when the IICE Air is switched back to -10 when used in combination with the IICE Cool. I don't know if you're thinking that.

Are you thinking to use them both together? The BP and the IICE Air I mean.

Hmmm...I don't want to combine variables or components until I can evaluate what each does as a stand-alone.

I had never thought of putting the BP and ICE in "series"; still don't think it is good idea. Hell, I am ignorant of if or how it could be done. I prefer to wait for 'Cool' to add to 'ICE'. I believe that will get me the optimal results I am looking for. I do realize that my slow speed, heavy engine loads in hot weather represents a very small percentage of what most owners are looking for.


Now a question for you; without reading all the posts, you state that -20 is the "factory" setting and -0 is stock sensor. What does"factory" refer to in regards to -20?

Thanks...Phil

It's not a repeat. It's me...get over it...thanks poolside...early Feb will be great for burning it up...

Where I'm sitting right here, that's the factory. And the IICE Airs leave the factory set to -20°C.

Thanks...too simple for my convoluted mind..hey if -10 is for hot weather, -30 for cold, I assume -20 is for all that stuff in between...ultimately I also assume that each rider, with differing bikes will need to experiment to find out the best setting for their riding style and bike setup under differing conditions. Sounds like fun to me.

Oh, you never elaborated on your original question about combining BP and ICE.

It's on BP's website. -20 deg seems to be the standard temperature "cheat" for all the rest of the similar products in the market which are non-adjustable.

I am under the impression that the BP and the ICE Air set at -20 would provide exactly the same performance. IIRC, you guys mentioned that before somewhere in this long thread. I just got a bit excited to try out something at another temp setting

Are are you saying that in combo with the forthcoming ICE Cool, the "temp cheat" would be similar to the performance of a -20 setting (but physically set at -10) but with the added bonus of fixing transient fueling issues? Very interesting if so...

Need some clarification. I am somewhat confused here. I always thought that -10 is for cold weather and -30 for hot. My thinking is that the ECU pumps in more fuel the colder the weather gets. Doesn't one need to adjust the temperature more as the weather gets hotter? I'm not sure what effect a small -10 adjustment would do if one were riding on 40 deg C weather.

Just saw the updated list and happy to find my initials and state on it. Looking forward to receiving mine whenever you get enough time to get them completed. Really appreciate yoiur putting something together like this.
