1390cc normally aspirated VW engine as fitted to Audi A2, Skoda Fabia, Seat Ibiza, VW Polo etc.

Mechanically very similar from AUA (2001) 75bhp to CGGB (2015) 85bhp.

Fitting the newer engine to an otherwise fully restored Audi A2 AUA.

Could original ECU be remapped to suit CGGB? Or would it require complete swap of later loom, ecu, bcu, clocks, keys. immob etc?

Cheers,
