Anyone on here had any experience with Motec engine management? I have a Blackbird with an M4. I quite fancy having a fiddle with it myself but am afraid the thing will stop working altogether when I plug my laptop into it.

If it aint broke don't try and fix it

Unfortunately it is 'broke' or at least not right. There Doesn't seem to be all that many people around that can deal with motec systems and the ones that can are a bit pricey and a fair distance away :0(
