That aside if you actually do plan on slashing and cutting all the wires so you can have the ecu in the engine bay.. you're being even a bigger idiot.

Or he just doesn't use the stock harness and builds his own harness. It's not rocket science.

I'm not interested in pnp. Now go back and rethink all of your conclusions.

edit: Realise that getting away from cutting and slashing and splicing a stinky-ass factory harness is a big part of what makes an in-bay ECU seem like a good idea.

Thought about it, still stupid to put a sensitive equipment in the engine bay.

I've got mine mounted where the A/C controls were. Let's you access the SD card and plugs, as well as letting you see the LED's so you can use them as indicators. I'll snag a pic when I swing by the shop tomorrow.

No idea if you can do this on factory harness. I've rewired the whole car.

Used to have a thin piece of aluminum sheet, but I prefer the plastic. You can barely see it in this pic, but you get the idea. Makes it super convenient for plugging in and having access to the SD card slot.

I'd like to see more/better pics of both of these installs. Is it still possible to fit a 1 DIN stereo, HVAC controls and a MS2/MS3 in there?

On my soon to be installed ms3x, I'm going to stuff it where the passenger airbag used to be.

Or attempt to.

We'll see

triple88a 12-19-2012 06:27 PM

Isnt your ecu on the driver side kick board?

18psi 12-19-2012 06:35 PM

yup

Yeah, totally forgot to snap a pic... I'll try to grab one tomorrow.

I could see you fitting it in the extra 1 DIN slot left from having a 1 DIN radio. Mount it in the bottom half and have the mounting flange hang below the opening.

MS3-Pro is rated -22°F to 176°F, limited by the internal back up battery. The other components are rated -40°F to 185°. Engine bay bay mounting is permissible so long as it is not exposed to direct heat from exhaust components.

Or you could water cool it like BMW likes to do. Because we all know how much sense it makes to water cool the ECU rather than relocate it to a better spot. Those Germans sure do have everything figure out.

Ben 12-20-2012 08:27 AM

What BMW uses a watercooled ECU? I've heard of air cooled ECUs in their newer stuff (because people complain about how loud the fan is).

Lol @ reference to $100k 2013 vehicle.

Gt2560rMiata 12-20-2012 10:31 AM

Watercooled ECUs installed near the catalytic convertor ???? holy stupid. Ill never own a German car

thenuge26 12-20-2012 11:32 AM

Brilliant engineers can be a good thing, but without someone to look at the big picture you get water-cooled ECUs installed next to exhaust components.

It's (probably) a great feat of engineering that would have saved a lot of time and money just by putting it somewhere else.

hustler 12-20-2012 11:54 AM

Gotta love Germans who'd rather mount heat-sensitive on top of cat converters and water cool them, rather than move them to somewhere, I don't know...inside the car?

You also need to realize that no one who posts on line normally has any fucking clue what most of the connectors for all the sensors and bits under the hood actually are. Or if they do they're holding on to that tidbit. I'm coming up with a partial list, but I only have the need to find 6 or so connectors and I've only figured out a few so far. Look in the general section for the thread on it, it would be great to figure out what the connectors are even if there is no source to buy them new, because we could at least figure out a source for pins to re-pin them to avoid any of those nasty wire splices.

As a BMW owner, I have to say that BMW's engineers are not the sort to let reason get in the way of logic.
