8hp45

I've gone down the 8HP45 rabbit hole and purchased one...

One of the nice things about having the N52 is that the swap should be mechanically trivial; anything from an N55 or N20 engine is a direct fit. I purchased a 40,000 mile box that came from an F30 328i (N20 engine) for $350.

I'm not sure exactly where I'm going with this, but I'll probably integrate it electronically using a CAN TCU controller and then have either paddle shifters or a sequential shifter (or both?). The weight appears to be about 45lbs more than my GS6-17 or 25 more than a GS6-37.

This won't be the first E30 application, that's been done a bunch already so I know it will fit.

Timeline is that I'll finish my last track events in September and then put the car on jacks, should have it driving again by the end of the year. Next year will be evaluation on the track!

I am sure it is too wide on the bottom to fit E30 tunnel.

Oh, ha- 'me too!' But I want to put it in the E39 wagon, behind an N52, and then play with tuning the transmission
controller so that it doesn't behave like the current GM slushbox that's in there now (and that I find so hateful)

So I'm in- there was one in a 528 at the Lake Stevens yard, and given that the engine was pretty well locked up,
I figure it's at least good enough to do development work on. (that car kicked my butt. I'm getting old.)
It's not a very big transmission- if it hits an E30 tunnel, it won't be by much.

What I'm trying to figure out- WHICH currently available controller gives you the most control over the transmission?
There's CANECU, MaxxECU, and the original... Turbolamik?

this is very much a 'back burner' project here, so I'll just shut up now and follow along...
