b58 bootmod3 max cooling setting
hey guys,
Just wondering everyones thoughts on the bootmod3 max cooling setting... i live in canada so the winters can get very cold but the summers can reach up to 30-35 degrees celcius. (stage 1 340i no bolt ons) questions: 1) are there any cons or risks in using the max cooling setting on bootmod3 year round? 2) do any of you use this setting and have any comments on it? thanks in advance |

1) No, it works only, when needed.
2) Yes, on stage 1 93. Not much to comment, though. According to the oil temp gauge, the temperature is slightly lower while pushing the car for longer period (as spirited driving up to the mountains, or longer summer highway journeys in speeds above 120 mph). Otherwise, no change. |

Would this make it take longer for the car to get up to temp?
I enabled it and went for a drive yesterday and It seemed to take longer. May just be me though.

I had the max cooling enabled on my Stage 1 BM3 tuned 340i xDrive and noticed that I could hear what sounded like a fan running constantly. I worried it would possibly prematurely wear the part (cooling pump?) so I disabled max cooling. I no longer hear the fan or pump sound. It almost sounds like the AC fan to me, so if anyone can confirm if that is the cooling pump, that would be great too. Hope this helps!

What are IAT's? Is there a post where all these acronyms are defined? I swear I can't read 2-3 sentences without reading some sort of acronym lol. Sorry fellas for the rant.

Call me skeptical, but with BMW's history of failed water pumps, I'm probably going to leave mine OEM.
"Moreover, for the B series engines this enables the intercooler pump to be active at all times to lower intake air temperatures!" - Directly from PTF/BM3 Having the pump active at all times doesn't sound good to me lol.

Mine just failed 2 weeks ago. Mechanical water pump replaced. About a couple months after the eccentric shaft was fixed. Hopefully that's it for me. Already out of warranty lol

I turned mine off because I'd rather the car run at the operating temp it's designed for instead of dropping to less than 190F every time a do a pull. |

Pump leaked where the bearing is. Service says it's worn out.
