Can a Raspbery Pi 4 be turned into an ECU for a high performance engine?

1. In theory the hardware no doubt has sufficient compute performance.

2. Most Operating Systems available for RPis are not real time ones with deterministic delay between inputs and outputs. Might be important in an ECU.

3. Though RPi hardware is just as reliable as that in a typical desktop or laptop computer I would hesitate to have one controlling an engine where misbehaviour could have serious consequences. And as you may have to write the software yourself how bug-free will that be?
