So the calibation should be already set, essentially for the life of the IP.

The "start of fuel delivery" timing would have to be set for each individual engine the IP is bolted to.

Sounds like a go then.

But I'm just asking out of curiosity now, the future might be anything.

As far as the timing chain stretch...I assume the IP would need to be re-timed every few years over the life of the engine.
