I am currently waiting for a G56 Emerald ECU as although G56 have hardware ready, they are working with Emerald to produce an updated version of the mapping. I assume when they have finished this there will be an update available to existing owners of the G56 Emerald ECU.
I will be curious to see what G56 does since i am not a car computer nerd nor do I really want to be. The ecu works well enough that most people would not know something is amiss but my 60 years of working on engines says differently. Once a map is generated then i would have to figure out how to install the blasted thing.
Physically hooking one up i can do, messing around in the software, no.
