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.


:-) ... this is also my experience... I did a lot of work on my harley sportster including the installing of a Thundermax ECM Autotune unit with the possivility to adjust something /everything by yourself.

Finaly I did the tuning of the full torque and speed curve with a professional shop used to handle it every day... the result was amazing...


Since we don't have a local shop to do the work I am selling my Emerald ECU. Once the engine is warmed up it runs great but the cold start is a bit lumpy, maybe by design? I also got a Zeitronix Wide Band o2 sensors and gauge that I never used that will go with the Emerald if interested. PM me.
