EDIS coilpack, LC-1 O2 sensor installation

Wednesday, September 9th, 2009



Coilpack mounted on the firewall just about where the distributor was so the cables I have will still be the right lengths. Also I made some standoffs for the coilpack to sit on, so it sits about 1/8″ off the firewall.


The gasket under the fusebox was all rotten and cracked so I bought a little sheet of rubber and made my own replacement. 🙂

This is where the O2 sensor and LC-1 end up sitting. It’s almost like I know what I’m doing! That little nylon clip inside the tunnel holding the wire up will be replaced with an aluminum one.


Working in the trunk!

Wiring and fuel line routing

Saturday, September 5th, 2009

Routing the fuel line turned out to be a little bit more difficult than I thought it would be and I was stuck trying to decide which way I wanted it to go.


Pulling the fuel tank. The in-tank pump made it really easy to drain it :V




Where I’d originally planned to put the fuel line. On the trunk side, it’s too high and exposed, and on the cabin side it’s also too high and interferes with the back seat.


The little dot in the bottom-middle is where the line will go through the firewall


I decided to have the line pass through this step (the big red thing) which is actually a big square channel beam that the differential hangs off from. That’s also why I had to remove the gas tank, or else the drill wouldn’t be able to go through it squarely



1/8″ bit going through the square channel to illustrate about where it is. The fuel line will pass through it, and then re enter the cabin under the rear seat. It should only be exposed to outside for about 1 foot, and runs just above the passenger side inner CV axle


Also the friendly UPS man delivered my LC-1 wideband controller 🙂

EDIS 36-1 trigger wheel mounting

Pulley is done after I put the missing tooth 90° ATDC instead of BTDC. Whoops!


The sharpie mark on the pulley is where the VR sensor sits, the keyway points toward the head at #1 TDC and the missing tooth is finally in the right spot.


The spacer ring thing was a bunch of JB Weld inside a tape “dam” around the circumference of the pulley, then turned down in the lathe to center the EDIS wheel. The wheel was then JB Welded in a few spots to secure it.

More later!

Still installing the megasquirt and its ancillaries

Nik and I have spent the last 3 days working on my car and there’s still at least one more day of work to do on it.


DB37 main harness going through a hole cut in the firewall. Its position is ideal because it’s not too close to the exhaust, and it’s close enough to the centerline that no wires will have to make any stupid bends. I had to move my brake lines but that shouldn’t be a problem.


All of the wiring in the engine bay was removed because it was all fucked up and horrible


DB37 connector inside the car, the MS unit will live in the glovebox.


Nik determining lengths for leads within the main harness


Me making the plate that the relays, fuse block and EDIS4 unit will reside on. It’s made out of an old street sign. Thanks, city of San Francisco


EDIS4 and fuse block with appropriate hardware


Panel on the firewall starting to be built


My roof became a storage area


While Nik was doing the hard stuff, I was going through the harness that went along the firewall and trying to figure out what each wire did. At some point the harness must have melted because for every wire there was a 12″ long extension, terminated at each end with spade connectors, and all wrapped in electrical tape. This doesn’t sound too bad until you learn that all of the extensions were cloth wire, good to about 400°F – that is, if it doesn’t get soaked in oil and/or gasoline like these undoubtedly had. One lead going to the coil had all of its insulation completely gone with bare wire exposed. FUN!

A while later…


IT’S PARTIALLY ALIVE


Late (’88-on) e30 325i fuel pump that drops into the stock tank. The E30 318is pumps are good too because they have the return fitting built into the pump in case your stock tank doesn’t have a return on it.


Messy, but the panel under the dash grows. Done for the night.

Tomorrow, routing the 5/16″ fuel feed and 3/8″ return lines.
