Looking through tis it looks like I can use the st170 loom with the focus rs ecu however there are obviously a few wiring issues as regards to the boost solenoid.

Most of the engine wiring is identical, I wanted to know whether it was a simple case of changing the pinout on the rs ecu so I can reuse the knock sensor and convert it to a boost sensor.

you know your stuff as regards to these oem ecu conversions and would like to be able to have a chat with you if you’d be happy to do that.

Thanks.
