I have no idea what ECU's the Morgans run, i suspect some kind of remap is possible with the existing one, talk with NMS would be my advice.

Fo me i needed an ECU to run the initial zetec on carbs and while only doing the spark control the web con alpha ECu originally had a non rewritable chip in it….hence locked. these days all chips are re writable so no real issue. I swapped to Omex as they had more features that i needed….different maps, launch control, clutch switch for full throttle shifts…..
