Re: Custom electronic fuel injection and ignition

Alright fellas. I think we got it figured out. I still don't know what I am doing, but it seems like my throttle body both flows too much air for the throttle body injected fuel to remain atomized properly. A redesign is in the works to get the airflow down to increase velocity (I think), and to rel...

Re: Custom electronic fuel injection and ignition

D, after thinking about it more, and a little experiment yesterday morning, I think you are right. Maybe you can spot my error, but I'm still digging... I pulled the fuel pump fuse, stuck a brand new plug in wire 3 and held it against the fender while I ran the starter. I had a very bright, consiste...

Re: Custom electronic fuel injection and ignition

I figured out that my extremely lean condition is not a sign of anything wrong with my electronics work, but that the engine is not having complete combustion in most of the cylinders, so there is an abundance of unburnt oxygen in the exhaust (where you want all the oxygen to be used up to make zoom...

Re: Custom electronic fuel injection and ignition

I wish I was a NASA team leader. I do know some folks who work at NASA in Huntsville, and I can't even pretend like I understand that stuff! I'm a bored-at-work software engineer by day, and an unreasonably unafraid disassembler of everything when I get home. Lambda sensor is installed and temporari...

Re: Custom electronic fuel injection and ignition

Alright guys, you convinced me. Going all-in with the wideband O2 sensor as well. After looking deeper into the documentation, it turns out my Innovate LM-2 portable wideband O2 tool can be wired into the Microsquirt, but my starter kit doesn't have the appropriate pigtail. That should be an easy fix.

Re: Custom electronic fuel injection and ignition

Still making progress! This weekend I got it starting and staying running without any help. It looks like as it warms up and the enrichment drops off, it starts getting unhappy, so I've got some tuning to do. So far as I can tell, everything is working. I guess I'll start making some real parts to r...

Re: Custom electronic fuel injection and ignition

It lives!!! There's still a lot of work to do, but it ran under its own power this afternoon. Before I blew anything up, I called that good and drank some beer. The two part trigger wheel turned out really well, and doesn't look too out of place on the engine. PXL_20211204_195659948.jpg PXL_20211204...

Re: Custom electronic fuel injection and ignition

I finally got up the nerve to try cutting aluminum on my Shapeoko, and the result was excellent, especially considering how sketchy my workholding was. I super glued the aluminum stock to a 3D printed fixture that was only clamped to the table with nylon toe clamps... It worked though! 9/16-18 threa...

Re: For sale in Gulfport MS

More details from the ad in case Facebook acts silly. "1960s Nissan Patrol looks like a jeep mixed with a land cruiser . Motor is freed up. Missing seats. Top is home made I think. Need it gone 1500$ firm no title but it’sold and that’s easy to attain" 249990002_4777191478978775_3813645569...

Re: Custom electronic fuel injection and ignition

After a little scope-creep, and some well-intentioned plans that turned out to be nightmares, the wiring is complete and validated. The combination fuse box and relay panel seemed like a grand idea, but wound up being a lot of extra work that I might should have done differently to look more in-line...
