I would be interested in hearing exactly what Morgan are claiming the ECU upgrade is meant to achieve and how the mapping is changed. I have no issues at all with the engine on my car, although a replacement manifold and cat improved the flat spot at low revs and perked it up a bit. (ok it doesn't start occasionally but you can't have everything)
I would assume that the same ECU has been fitted to every GDI but it appears that only some have issues, such as high revs on startup, so is the problem not the ECU at all and something else?
Thanks for the feedback and based on that I will stick with the set up as it is until more information is available
