Nice work!

Can you inform me about the cluster swap with 9.000rpm?

Thank you!

I sent it out to e30_dad for a complete once over.

Really great guy to deal with :up:

Figured it out...

Ended up being dirty/corroded ends on the ground strap! I forgot that I cleaned the lugs and the nuts but not the strap itself. Simple problem... moving on to the rest of the damn thing.

FYI it took me all day to get to the bottom of this. Sigh at least I got it.

Having a strange charging issue.

Upon start I see about 11v output and then within 3 seconds climbs to 13v. At the battery I see approximately 13.15v.

The alternator is new (not a reman) and I've checked my grounds plus resistance.

- Chassis to engine
- Chassis to specific points on the block (tstat housing, cylinder head, and alternator)

All read 0.0.

I swapped my battery for another good one that had about 12.14v which didn't change anything. I think it could be the alternator. Unplugging the exciter connector drops voltage to 11v.

I reached out to Andrew to ask him how the battery indicator works since the ECU on mss54 receives the signal from the alternator to make sure that circuit doesn't have any breaks... just dont know where to look.

Any other suggestions?

Got a heavy hit of nostalgia seeing the plastic welding with the screw driver. I used to do that with my toys using a butter knife and the stove when I was a kid.
My mom would get angry at me and finally designated a single knife for me for whenever I would need to do it again.

lol, that is a good mom. some parents would just yell at their kids vs giving them a healthy option like a single butter knife to use. :D

I need to update my Gen 1 wiring schematic. Gary just got back to me. The AC Pressure sensor ground connects to the same ground as the CAN controller, because it is a low voltage signal and you do not want voltage float differing between the CAN controller and AC Pressure sensor. The Gen 2 schematic is correct, but it has a pin also for AC Pressure sensor ground, which also gets chassis grounded.

Nice, I'm actually following the *Gen2* schematic that you made up so I should be in the clear. My buddy is parting out an E46 wagon... still waiting for him to grab those parts off of it :up:

So great, I'd love to S54 swap one of my turds.

Just make sure you pay attention to the common failure points on these motors and address them before dropping the motor in!

Great thread! Thanks for sharing

Thank you.

Congrats!!! The look of "Oh HELL YA! We did it!!" is great to see! So stoked for you!

Thank you :) Now I have to build out the exhaust... I wish I could leave it like that. It nearly sounds like an aircooled Porsche!

woooO! Such a good feeling

Haha indeed man! Can't wait to drive this thing.

Oh and I do apologize for the crappy voice/video sync. I have no idea how to fix that.
