not yet using the MS live yet John but its now configured to run using oem sensors. apparently, no one has yet alpha tested MS with weber marelli tach signals but ive got the engine idling on it running sequential coil on plugs.

they are toyaota yaris as you say but maching the bosses down 5mm will not be enough, you need about 20-25mm and the boss in only 15mm. i'm currently modding the yaris coils to extend them down. the mounting bolt hole for the COP exactly aligns up with the cam cover securing bolts and with an 18mm spacer will make for a neat install.

Simon, i just read a post of yours where you said this was imminent for oem ecu but that post was 2005!

my concern is more about the heat issue using these as they do get quite hot (even with attention paid to the dwell) and with the heat of the engine i'm just a little concerned about heat
