Very slick. Can I send you my e38 and have you make one?

I should be able to borrow an e38 ecu locally.  Looks easier to make a mount for it than the ls1 ecu.  Just let me know how the e38 needs to be orientated (pins up or down, if up, how much clearance needed, etc).

The hex head bolts in the pic are actually 5/16" lag screws that go into those plastic pieces sticking down from the evaporator box.  Feels solid - couldn't think of another way to mount it that didn't use a big bracket that would require separate prints.  The ls1 rear mount was hard to install since the lag screws wanted to sit directly above the ecu and the cover bolts were almost impossible to get to with it in place.  Too lazy to fix the design now since it seems to work.

Nice....How much?  I could use one...I don't have as much space as I used to in the kick panel, other items seemed to take up that space.

Got a e38 ecu and made a bracket.  The bottom piece gets sandwiched between the top piece and the ecu.  I need to reprint the bottom piece for recessed bolt holes so the heads don't hit the cover.  Came out a lot nicer than the ls1 bracket.  Making it two piece saved me from having to make support structures and it wouldn't fit on the platform.  Printing stuff parallel to the platform without anything underneath doesn't work for gaps bigger than ~1/8".

It takes forever to print so I don't want to make too many of them.  I'll post up the source files once it's test fitted in place.  It's just a few dollars in plastic and labor is cheap after the design part.  :)  If you want one, send me a PM.

Looks like it fits with recessed holes on the bottom bracket.  I installed some heli-coils as suggested by wickedrx7 and only had one bolt of the right length.  Had to hold up the other side with my ratchet.  :)

You design some killer pieces!  :cheers:

Looks like your printer is nicely calibrated, too. I'm being far too lazy to get mine printing that clean.

That's sure slick. How far will the ecu hang down with that bracket? I want one if my passengers won't be kicking it by accident  :wave:.

It's about 1/2" below the lowest point on the evap box centered on those 4 posts.  If I was using a e38 or similar sized ecu I'd mount it in the right panel.  My ls1 ecu and wiring would require too much work to get behind there.  I sat in my passenger seat and didn't have a problem with hitting the ls1, but then again, I wasn't trying to either.  The pictures are deceptive since they are taken at foot level.  If your passenger likes to kick the evap box and glove box then they are now going to kick the ecu.  Mattster is making a footrest mount that looks to offer nice protection from dangerous passengers.
