Fuel injection reload
Enclosed pictures of my latest version Flathead. New EM-TRON Ecu
can tune each cylinder. Will take spark out of a cylinder that is detonating and put it back in asap. 2 & 3 do not like each other and they will swap detonation often. The EM-TRON recognizes it and tunes that individual cylinder to stop the detonation. The cylinders can also be tuned with pressure reading spark plugs. You advance the spark in a cylinder till the pressure falls off then retard a bit. You need a very good engine dyno to accomplish these features. engine has 8 coils. Put 1400 miles on it the last 3 weeks and it has never ever been this happy. French block 304 cu in Isky max 1 on 108 centers. 8 1/2 to 1 Com. cranking pressure, 160 lbs. |

Re: Fuel injection reload
Really nice work. I love your crank trigger ignition Did you do the machine work? It looks as good as it works I bet. Are you running a intercooler or is that just your intake .

Re: Fuel injection reload
Hello Quickchange
To answer your question, I do all the machine work. The item that looks like an intercooler, is a plenum. It sits on top of the original throttle bodies that I removed the throttle plates and made smooth runners. I had developed the runner lenght earlier and didn't want to mess with it. It cold starts before the belt makes a loop. We will be installing the cruise map this week. It will have a town map and a highway map. Just flip a switch. I am looking to swap of the C4 for a 4 or 5 speed. It will pull more gear even with the Columbia engaged. Dick in Havasu Az PS Enclosed picture of another build that might interest you. |

Re: Fuel injection reload
Kerker , Your work is killing I am very impress with both cars, Your attention to detail is off the chart. I am working on a Ardun in my shop for my latest project. I have been trying to get the correct intake runner length for the side draft Webers going on the Scott blower . I have the base plate and plenum made working on runner lenght I wish I was smart enough to do fuel injection. Its even more efficient than webers.

Re: Fuel injection reload
I think an engine management system is the future of our old engines. They need not be designed for preformance, but economy and reliable operation with present day fuels. A stock engine wuld always be in proper tune under any operating condition. The best of both worlds. I understand someone maked a throttle body that looks like a Stromburg 97. Can't beat that with a stick.

Re: Fuel injection reload
Regarding the crank trigger in the first photo posted, what is the purpose of the gap at the 1 o'clock area?

Re: Fuel injection reload
Hi Mike
The gap tells the computer the position of the crank relative to firing #1 every 720 degrees. The slots on the front of the wheel are for turning the engine with a custom spanner wrench. |

Re: Fuel injection reload
I get it...I'd counted the teeth and figure if two more were there, you'd have 24...and maybe using some sort of waste spark on other cylinders...man I over thought it..lol!
Awesome work you've done there. |

Re: Fuel injection reload
I am a techno junkie. I love bells and whistles, however the computer driven injector seems out of place on a flattie. g

Re: Fuel injection reload
You need a sensor on the camshaft so the engine knows where Number 1 cyl is,on the set up my boy made for his 6 cal holden engine he made on to fit inside the cam gear.
