jonnyfox Posted July 27, 2015 Share Posted July 27, 2015 So I'm a proud owner of a Emerald M3D ECU! Anything I should know..... Good points, bad points...... Link to comment Share on other sites More sharing options...
dobbo Posted July 27, 2015 Share Posted July 27, 2015 It's an old-ish model. The K3 and then the K6 have replaced it. As with all Emerald ECUs (except that one recently on SELOC with an old DIN socket), the software and manuals are on their website. Later M3Ds can be upgraded to K3 spec. If you send your serial number to Emerald, they'll tell you if it can. If it can be upgraded, I'd do it. I had the M3D on the old DVA engine. It worked fine for that engine - reliable, easy to tweak, etc. If you want live switchable maps and some more bells and whistles, you need K3 or K6.

@ndy Posted July 28, 2015 Share Posted July 28, 2015 Mine runs an M3D Emerald with no problems..... You can manually swap the maps via a PC if you need to for an MOT etc. Link to comment Share on other sites More sharing options...

Alex B Posted July 29, 2015 Share Posted July 29, 2015 M3D will struggle with a lightened fly wheels due to the pick up points on it. There's a k3 for sale on Seloc. Link to comment Share on other sites More sharing options...
@ndy Posted July 29, 2015 Share Posted July 29, 2015 I run a lightened flywheel with no problems..... I think it was some of the early flywheels that had the problem, Mine is a Seriuosly Lotus one Link to comment Share on other sites More sharing options...
