This doesn't really have much to do with the Megasquirt install, more of dealing with the customized 4bbl intake and the problems it created.

I moved the plate the holds the coils a little higher on the valve cover to fix the clearance issue against the heater box. When I put things back together, then I noticed that the valve cover itself was touching too. Cut off the corner, weld in a small filler piece and that is fixed.

The 4bbl throttle body needed a cable bracket for accelerator and TV cable. Also had to make a lengthened tab for the TV cable attachment "nub". The brackets that hold the fuel rails required the bracket sit a little farther away than normal.

Intake pipe got fitted and welded up. It is right in the way of the upper radiator hose going to the thermostat housing. Mine come out of the top instead of the front. So, I made a custom job to go under the intake pipe. I'm going to add an air bleed screw at the top, the bung just hasn't showed up yet. I might not work at all.

The car is packed away for winter. If I had a heated garage, work might continue, but for now it's too cold and I'm too old. I really only need to hook up fuel lines and run the ECU to somewhere in the cabin.

I did find a pic of the day I bought it. Not sure of exact date, but photograph had a date on the back when it was developed of Dec 88.

33 freakin years ago. Damn I feel old.

No real work done on the car yet, as it's still to cold to be enjoyable, but I did come up with a place for the ECU. Current plan is to relocate the battery to the trunk and put the ECU in the stock battery location. The boys got a 3D printer for Christmas and I did my first real project with it.

It should keep the MS3box pretty well protected and I can still communicate with it via the bluetooth adapter.
I figure it used about $15 worth of PLA (the 3D printer plastic "wire") and took 29 hours to print.

Cool project nicely done. Where are you in Ohio?
About 30 miles north of Columbus out in the boonies. Hoping to get the car to run tomorrow! Got 2nd covid shot today and taking tomorrow off work to work in wiring. A bunch of relays and fuses to get wired up. Going to make sure it runs before I try to make it "pretty". I did move the battery to the spare tire well to make room for the ECU up front.

I'm having trouble getting my laptop to see the MS3 using the bluetooth adapter. I an see the adapter, but Tuner Studio can't communicate with the MS3. I'll try some different laptops and various phones tomorrow before I completely give up. Open to any suggestions about this.

Next steps for this summer:
intercooler (buy tubing & weld)
E-85 (adding flex fuel sensor)
rebuild rear axle (might just hire that done)

Then it is done until the transmission blows up. It is a fresh stock rebuild so it may last a little while. I have a BRF in the barn that I may just run up to Janis transmissions (or go with manual).

Eventually:
manual boost controller
digital dash display
