Frustrating I can imagine, is there a way to get to the back side to push through and remove the posts that remained? Might have to clean it up and remove the posts then drop it in and solder, you can try some thin braided wire to remove solder...or a little spring loaded vacuum.

Requires more digging in the potting.. meh... I might see if I can run over to ace and get some thinner solder. Think the stuff I have is a tad too thick. It's really a matter of getting everything in place and trying to fit the solder and iron in there and somehow keep it from moving..
use either a solder sucker or a desoldering braid to remove the old solder from the board and remove the old posts. Be careful with your heat not to pull up any traces...
After you get the old out, use some flux and install the new.

Ok... here's where I'm at...needle nose pliers worked great for the back. Trying to get the old solder hot enuf to pull the old pins.. proving futile at the moment...

Are you holding the pins with the pliers while you try and heat it? If so they're acting like a heatsink. You need to heat with the iron until they move and quick grab with the pliers.
It's also possible on the negative side the ground plane is soaking up all the heat.
Putting some flux paste on it can help getting the old solder to flow.

Belay my last... finally managed to get the 2 posts out... cleaned up the 2 holes and installed the new diode...will hook everything back up in a bit and see if it worked... fingers crossed

Hard fought, tedious, scary buy well worth it... just gotta seal it up and install... next up is the fuel system... carb rebuild and those dang tempo lines... easy compared to electrical
Great to see, glad you could bring it back from the dead!
I'm the opposite, I can do electrical all day. Problem with the mpems though is there's no technical data, schematics, etc... kinda hard to fix when you don't know how it works lol.
Read mikis carb rebuild thread, use oe mikuni parts, and make sure those pilot holes are all clear. Pressure test the fuel system when you're done.

Cranked her up this morning... idles around 3k and sounds smooth... couldn't help myself.. had to make sure she cranked... dont think its ran in quite a few years but she purrs...still gotta seal up the mpem and put the rest back together..
I'm not sure what you have for electronics hobby stores but potting compound is what you took off, replacing it with the same probably isn't a bad idea so the board stays sealed.
This is what's readily available in my area:
832B - Black Epoxy - MG Chemicals | MG Chemicals
Any bit of airborne moisture that can seep in will corrode any circuitry you exposed. On the flip side that stuff will be a bi*** to remove if you have to do it again.

I totally missed this post.. Sorry K.. Does that stuff turn in to epoxy concrete or does it stay plyable? If I have to dig this thing out again, I dont want to have to deal with solid epoxy
Nope turns hard like the stuff you removed.

How do you test the mpem

Well done! I just put a mothballed '97 gsi back in the water with a new(core exchange) SBT motor. I put about 3 hours on the new motor yesterday. Running strong clocked it at 53 mph along side of my 2013 gti.
I also replaced most of my fuel lines they were in pretty bad shape.
For a winter project I plan on pulling the fuel baffle and doing the solder repair.

Awesome! I love bringing things back from the dead... fuel lines on this one are good but they'll be replaced this winter...
I've gotta do a float on my gts
