Documenting my conversion to EFI/distributorless

In the first pic it looks like you are using Push-loc hose for the fuel line.
You don't want to use clamps on those fittings because the clamp puts pressure on the barbs and will cut the hose.
That style of hose and nipple doesn't need a clamp.

It is pushlock from Parker. I will take the clamps off.

Ohhh, that weird GM single line feed deadhead system. That caught my eye a while back because I love the idea of running one high pressure back to motor and doing all the feed/swirl/return/filter/regulate in the nose.

Are you going to do it GM like and not the big loop recirculation like?

^^^ what he said.
Carefully cut the line back and push it back on, no clamp, you might get away with it very close to the plastic collar away from the barbs.
If you tightened the clamp over the barbs, the hose liner is already destroyed.

Yes, the only thing running the full length of the car from the tank to the motor will be the fuel supply to the rails. The return from the regulator will go to the CB Performance T and that is under the fuel tank.

I am going to try a Speeduino board, this one is V0.3.4.


The empty socket is for the VR conditioner which I have not installed yet.

This is the first that I have heard of/seen that ECU. Seems very stripped down, but also low cost. I can't comment on it, but the bad thing, is that you won't be able to get much support from this group since this is a uncommon ECU.

Good work though.

Someone had mentioned it here previously. I had not heard of it before then.

It tunes with TunerStudio.

I got an error saying the image sizes could not be determined so I've linked to the images.

It's making noises all on it's own now.

Cool.
What are the coil mounts?

Some ABS plastic 3D printed parts.

I really need to build one of those... Both ECU and 3D printer...
The complete, assembled .4 ECU is $160?

We're scrapping out an old pick and place tool at work that really wants to be a giant 3D printer, has all perfectly great hardware, just the vendor won't support it any longer, and direct replacement parts (need for a real used-in-manufacturing tool) aren't a thing.

Has a ~48x36x24" high work space, and all the hardware and Cognex vision system worked..
Unfortunately its built on a giant granite slab/optical table setup and probably weighs >10K pounds.

Yes, I have a v.0.3 that I assembled myself and it was roughly $100 for all of the components.

That's cheap! I might have to grab one and lash up a spark only rig to start.
