Hey guys, just been reading the thread and I can say i didnt understand much of it, but . . . I had my mate who is a sparkie to try and make my factory RA23 tacho working with a 1g + motec. It was kinda working but not quite, bit all over the shop so we gave up. Would it be possible to make it work correctly with all of this stuff you guys are on about or is this tacho just too old school?

Hey I'm having a similar problem with my set up and would love to build this gadget - but the photos arent working? Anyone have a link to a diagram? Or is just my computer? Will check it on the work one tommorrow...
