Anyone run this Voodoo cam ?

I understand the logic, but IMHO this cam should tune up with no big issues with a decent mixture at idle.

Now here is something else worth considering: With the O2 sensor, if things are rich, the sensor IS going to give you wrong readings at cold and warmup idle. The reason is that the O2 sensor sees ONLY free oxygen. It never 'sees' the raw fuel in the exhaust.

So, at cold and warmup idle, when some of the fuel is not getting burned, then the input mixture can be perfect, but not all fuel is being burned and some of the oxygen is also not being used up. So there is excessive free oxygen in the exhaust, and the wideband interprets this as lean.
Guys then richen things up to try to make the wideband read right and go way too rich.

The only time the wideband will give you accurate readings is when everything is good and hot.

So that could be an issue here....
