- At high loads for extended periods of time the oil and water temperature ran much to warm. If these were to be left unchecked it could result in damage to the pistons and cylinder walls. To fix this Dinan remapped the water pump to keep temperatures under control.
Can procede do this too? |

I agree. I'll bet you right now for 2009 cars we'll see slightly larger oil coolers, larger more efficient water pumps, possibly slightly larger and more efficient FMIC and a few other little changes to make the 335i (and upcoming 135i) run a bit cooler and therefore produce a bit more power for longer periods without limp modes and the cut power that follows. |

On the track the pump is 100% so kind of not so cool feature and it is just about hype. I'm sure Shiv would have commnet about this also. Orb |

Your guess is as good as mine. That was a quote from Dinans press release. My guess is that the cooler comes on at lower temps than normal and or stays on for longer periods of time. Of course these are just guesses and I am not sure how the cooler works exactly.
I am sure Dinan would answer these questions... Jason

From the sound of it, it sounds like the water pump speeds change together with boost. Maybe the factory system controls the water pump based on temperature only, but Dinan mapped it to increase together with boost increases.
===================================== Remapped Water Pump Speeds. In an effort to more effectively control oil and water temperatures, which have been notably excessive even at stock boost pressures, the Dinan software actually increases water pump speeds as boost pressure increases. A much larger, more efficiently ducted oil cooler has also been developed, further improving heat exchange for lower and more consistent operating temperatures, even with the added boost pressure.

I remember when I had dinan's reflash on my E46 M3. M3forum would laugh saying it added zero hp. Now dinan cums out with hp to be added to the 335. Iampro dinan +1 i'm getting my installed. fuck yes!

You'll need a water pump to match it.

Wow, a lot of misconception all over the place here. A bigger RAD will do nothing if you can not reject the heat into it. The cooling system is as good as it weakest link and they all have them. Overdriving a pump that has flow rates close to optimal for a give RAD is simply not going to get you very much more. You will use a lot more power to drive the pump for diminishing return due to efficiency.
Using water wetter or similar product will do more than increasing the pump speed. It actually a very good band aid for those hot spots and that were the focus should be. Orb |

I recall that some of the reasons you gave for switching the HW to the Halltech was the availability of more I/O channels - hopefully there is one left currently that could be used for something like this. Assuming it does something, of course. |
