I think he got quite close but I never saw the outcome.
Aftermarket ECUs have moved on a long way since then so you may find an ECU that will run the Toyota engine and give outputs suitable for the Focus gauges.
Been speaking to brands hatch performance and they recon it’s possible but not entirely sure based on other people’s issues that I’ve read.
I didnt really like that “bolt in” kit tbh. Don’t like the solid axle rear end, the front cradle looked a little anaemic and it was ridiculously expensive lol
