Ebay GT45 + 5.9 Magnum + E85 blow thru

Subcom, please do not take this as criticism, but your crank sensor mount seems suspect to me. If it is flimsy at all you will fight it. That sensor and it’s air gap are crucial and if you can grab it by hand and change the air gap at all, vibration will do the same thing when it’s running. It could just be the pictures but I would make that mount much stronger.
You’re right. The Megasquirt manual calls that out as being very crucial. Mine isn’t the thickest material but it does have a gusset behind it you can’t see.
I got the engine running again after finding the cam sensor had a bad connection. The tooth/compound logger looks good now for both the crank trigger and cam sensor. The idle just hunts like crazy, swinging the AFRs to really lean which was a problem I had running on the distributor and fixed by massaging the VE table. Gonna take some more tweaking but it’s getting closer. Thanks.
