Hey Nate - Here's a really good tech article on AFR tuning by John @ aircooled.net. Lots of information to digest, but a great read and reference -- https://www.aircooled.net/how-to-use-a- ... -4-engine/

The little 2058 has been running well! My final jetting is 55 idles, F11 e-tubes, 130 mains and 230 a/c's. That is giving me a good average drive where its not overly rich all the time but wot. 225 a/c's definitely give me a better wot afr but then its on the rich side everywhere else. It's close enough for some carbs.Image

I tried running my breather on manifold vacuum but it actually made the car run really lean on cruise i had to have the throttle plates almost closed for a 900 rpm idle so I put the breather back to atmosphere and cracked open the idle bypass screws to get the throttle plates where they needed to be.

Soby far I have about 1100 miles on it and I did find a shim that was bent on the rocker arm, it was a .015 shim on the outside and a .030 shim on the inside by the rocker block. I grabbed a new .015 shim and swapped the shims so the .030 shim on the outside and re adjusted the valves. And the damn throttle cable broke when i was out driving the wheels off it, got lucky in having spare parts in the car to get me home:)

Did a little quick video after I cleaned the garage today had to Christen the new garage:)

Fired it up last night with my Nodiz pro ignition only ecu and dubshop hidden crank trigger! It fired right up after i set the cps sensor offset and hooked the plug wires to the coil correctly!Image

How many coils you using Nate?
Does that thing still use the dizzy for cam position sensing?

Cheers

I am using this coil, a few years back I bought this setup from the Uk that came with the ecu, universal harness, map sensor and a coil. I should have just bought a megasquirt(which I now own) but I've got a few things I'm going to experiment with on this motor so I figured why not have some fun and go crankfired:) as of now I am still carburated so no need for a cam sync but might in the future time will tell. I have been having fun showing that video to some of the old guys at work and asking them how does it keep running?! Image they get so confused its hilarious so ill probably just leave a dummy dizzy in there for a whileImage

Hahahah, thats cruel :wink:
Looks like a Ford unit so that will be wasted spark.

Your motor already sounds good so cant wait to see what its like with FI using the MS..

Thanks Marc:)

It is in wasted spark and from what I can tell its off a newer ford from the uk. I reset the cps offset last night and messed around with the timing map and it is much happier now:) I still have to hook the map sensor up for a full 3d ignition but at the moment it's already running better:) im sure I can now open up the plug gap some ill have to do some research on a good gap
