Budget WBO2 wideband controller roundup

I wanted some wideband o2 in the car. Partly because almost all EFI controllers will still rely on a separate wbo2 controller. Partly just to have a gauge which I can keep an eye on. I prepared a small comparison about the controllers I've found.

The head #2

After some busy weeks, it seems I never catch up with myself about the engine project. It is indeed running fine for some time already. But, back to the head now...

The head

I'm spending some time cleaning up my cylinder head now that it's off. No big things, cleaning, changing valve stem seals. The valve seats looked like the moon, so I also decided to lap them.

Current project: engine rebuild

I have good previous experience by rebuilding an engine in the car, down to changing piston rings.
