@ Jano - alright mate, I have a v4 here, would you like me to send it to you for a play along with the software so you can have a good look around it? its gonna be a while before its in my motor lol so you are more than welcome mate. You may be suprised with the amount of features for the overall purchase price.

I can't comment about these ecu's as I don't have any indepth knowlede, all I know is that when I was researching into which ecu to buy the ms/v4's offeres everything at less than half the price of the others, also the mapping software interface can be changed to accomodate what the mapper is used to so in theory most competatnt mappers should be able to map it.

Im thinking of getting rid of my v4 and purchasing the ms ecu that rick mentioned from the states but not made my mind up yet.
