New Fuel Injection Build

[Auto Anatomy]

Good afternoon all! Just wanted to post a few quick updates about the new fuel injection system I've been building for my LM.

I know that Ted Brown makes a great bolt on kit, but wanted to take a slightly different route. This is version 1.0, and will be bank fired and controlled by a microsquirt system. Currently it has a single 55# injector feeding each bank, with a single fox body Mustang throttle body. The first iteration may keep the distributor and be fuel-only, but eventually will get a Ford EDIS system with crank trigger, allowing full spark and fuel control.

Ultimately I'd like to get some 140 heads and make a true sequential system with 6 injectors. So this is more proof of concept, & should have a video out soon documenting the build.

Your fabrication skills are amazing. Looking forward to seeing the video for this!

Wow, did you bend and fab those intake pipes? I agree, they look really good and it sounds like you have a good plan. Definitely keep us updated!

I purchased some bends and cut/welded them to make the intake.

Looking good! Is that as mass air flow sensor front right? And what’s the little aluminum box on the front left on the firewall? I’m looking forward to the video. Ken

Mass air flow sensor on the right, and the aluminum block on the left is a vacuum distribution block with a MAP sensor.

Nice job mating the mandrel bends to the throttle mount! Tricky stuff

Is the throttle drive by wire or is it cable driven?

It will be cable operated

Thanks for sharing! Nice cliffhanger too and I'm curious to see what you do for the throttle linkage.

What a great video!! Every single person who has gone through an initial startup has said the same thing, and it is such a great feeling when it fires and runs!! Nice job!!

It's up and driving, but need to rethink the PCV system. It's not drawing enough air out of the crankcase and allowing pressure to build up. I've seen some adjustable PCV valves, but am thinking about a system to use Holley fuel jets as a restriction. That way it can be easily changed if needed.

No doubt about that! As far as using Holley jets for the PCV, I feel like I've seen people do that (maybe even epoxying and tapping the PCV hole to accept a jet?).

Why not just make it a real Positive Crankcase Ventilation System. Tap in ahead of your mass air flow sensor and run a hose with the clean air into the oil fill pipe. Then connect a PCV valve between the stock crankcase opening and the balance tube. No orifice needed or wanted. Now you will have a positive flow thru the engine instead of having a road draft tube type system with the orifice. If you only have 1 opening for the clean air to go in and the blow by to come out then it is a road draft type system.

That's a great idea and I'll definitely do something like that. Thank you, and my garage floor thanks you too!
