Sorry: I had to laugh about the ECU on the seat! That is funny!

I had a similar experience , I converted a RR to Multiport EFI with crank trigger & & computer controlled ign system while testing it to make sure everything was working it fired up& ran which surprised me as I was only testing the circuitry !!
Congrats on getting it running !!

Was written exactly for a laugh. I was able to when it fired.

Thanks it does feel good. Have to say I noticed immediately that it was idling smoother.
My only "on" suprise was the blinker working.
Back to bathroom remodel today. 

[YellowThumper]

Avoided the bathroom remodel again and spent some hours cleaning up the wiring. One by one cut and soldered them to the new plug. Digging out each strand from the birds nest.
Was not initially expecting to get this far but got on a decent rythm.
This is the first time I have had a passenger floorboard in 4 years.
Will now mount ECU in the partial center console so wiring will clean up further.
A few more wires will need to be added soon for the idle air valve.
For now I will get the timing table set and drive it.

Removed a few more unnecessary items, sealed and tied of the wiring.
Took it out on its maiden voyage with the MS in control. Very basic timing table keeping it conservative. Wideband remains off. The thing runs pig rich and don't want to ruin it before I have time to try and dial that in.

MS drive portion was uneventful.
But primary start to this round was a bad cooling fan. Wiring that had been patched and patched again.
New wiring and new fans as well. New PWM controller did not work. !@#$%. $160 piece of junk right out of the box.

Anyone have a brand controller they would recommend?

Let's get some video for us. We have been waiting for awhile now.

Guess I could work on that. Don't have a YouTube account so it gets cumbersome.

Now for the idiot award for the day.
PWM controller is now functioning properly.
I had 2 fuses. One was blown from original fan issue. And the replacement good one. Yep mixed them up and put in the already blown one. 
Took another test ride today and all worked well as it should.

Next plan it to dial in cam trigger.
Oh... and drive it.

Nice progress.

[Shoooter]

You have made great steps. Can't wait for more updates

In disgust I pulled the keys and tossed them onto passenger seat. Right next to the ECU box sitting there not plugged in...

That totally sounds like something I would do.

Still basking in some functional glory. I decided to hack up the plenum. One of the struggles has been how to make a tight connection while making a quick turn towards the front. Plenum has to face sidways because there is no room forward. Magnum accessories are in the way.cutting the face off and milled housing. Will be about an inch shorter and will allow for a silicone adapter reducer.

I used this on my old turbo project.  Easy starting point for what you need.

In hindsight that would have been a simpler approach.
Already have the TB for it. Have made the mounting brackets and cable setup for throttle as well.
Sticking with my "vision" but will definitely opt for another change if this becomes a stalling point.
Current mod is just another bit part of many open items on the list.

Took it to work today. Suprising how much smoother it runs on the coilpacks.
Parking is no issue.
