Mick, I'm sure you are aware that all the fault codes, which ever reader you use for the 14CUX, are all related to the fuel system, there are none for the ignition side of the engine. That said, if you have an engine problem and there are no credible fuel error codes, it suggests that the problem is electrical.
Mark at Mark@blitzracing.co.uk does a good deal on a bespoke cable, Rovergauge software, instructions and review articles, highly recommended.
