I'm curious: When swapping an alternate fuel injected engine into an early Miata, how hard is it to get working gauges on the factory cluster? (tach, temp & oil pressure etc). Engine would be controlled with Megasquirt.

The ECU outputs those signals, so Megasquirt would be taking care of it.

Answer: Easy.

Actually the oil pressure gauge on an NA is directly hooked up to the sender so all you need is to swap over the sender unit to the later engine.
