A couple of years on from her original EVT700 build this car came back to us for a hardware and software update with EVOMS' latest EVT775 upgrade, including the dual-mode ECU for 91/100 octane (the switch is hidden in the ashtray). Since then she's also added a set of TechArt GT Street Side Skirts and all-black 19 inch HRE 893R wheels.

Here we are with the ECU/DME open and installing the necessary EPROMS for two fully-functioning ECUs. The EVOMSit software is then burned to each EPROM.
