Chevy Nova Megasquirt conversion.

It's not a Rover, so it belongs in the Lounge rather than the engine section, but it's of interest if purely for the DIY junkyard aspect of it all:

That's an interesting read, good to see someone with access to a dyno doing a full on comparison between different common carbs and a basic Megasquirt fuel system. It's also fascinating to see how close the Megasquirt matches the best of the carbs for that particular engine.

The second part on ignition management is also a pretty good read

That is very similar to my experience of changing from distributer to mappable coilpack ignition, the engines just run smooth and pull harder. It's so easy to tweak the timing over specific combinations of rpm and load to squeeze a bit more out of the engine.

plus if you get really keen and depending on the ECU, have switchable maps for different fuel RON types.

91 RON for during the week, 98 RON for Saturday nights.
