Blackfly XFi?



Thanks to a certain website overlord who shall remain nameless, I now have in my posession a camshaft from a Metro XFi (year and mileage unknown).

This cam will find its way into the Blackfly's engine compartment in the not too distant future, replacing the extravagantly wasteful OEM cam that came with the car.

Wouldn't you need the ECU as well?

Should only be about as tough as changing a flat without stopping.

Congratulations. I wish I were able to make some practical tradeoffs of power for efficiency in my car, e.g. a smaller engine, but I haven't seen anything yet that wouldn't require major surgery or drastically impact the reliability.

You can build a DET CAN for detecting knock...it's always amusing when mechanical solutions are better than electronic.

No problem. Just don't let the police see you driving down the road with headphones on! Imagine how strange it would be when a cop looked in the car and saw hoses running from the headphones to the engine!

CoyoteX posted a cheapie microphone-based ping detection method too. One or the other will come in handy, yes.

I would love to see a side-by-side comparison of the two cams. My functional engine knowledge is not the best.
