Hey Truckinfavis,
I've got 4 of those bongo engines and one FE3 engine. My daily driver has the exact engine that you have a pic of:
I'm running Megasquirt on it and it works fantastic.
My other truck is a project that I'm still working on but I have a bongo engine with the 929 manifold:
This one is running a Mazda 626 ECM conversion which was developed by my friend Madlowmazda Jim.
My two other Bongo engines are not yet in trucks but I have one more E2000/Bongo manifold and I've got three carbureted manifolds imported from Finland that will allow the use of a Weber on one of these 12v engines...that will be in my next project.
And heres a pic of the FE3 I'm building for yet another future project:
I see you live in Marysville. If you're ever up in Bellingham, give me a shout and swing by my shop!
