Ecm questions 2007 m1000

[buckie]

Ok so im curious what the difference between the circle, triangle, and square ecms for my m1000 everyone seems to say the square is the better but no info on why, curious if anyone could shed light on this for me??

all I know about them is they must match the same "shape" on the injectors, do NOT mix & match.

Well thats a damn good thing to know thanks bud

yep, they are not interchangeable unfortunately. Too many reasons to list why. The shape is written right on the top of your ECM, bottom right-central area.

Ya you bet, so its it just mapping differences? Or?

So I'm looking for a circle ECM for a 2007 m1000. If you have one or know where I can get a used one would appreciate the info.

barring that, if I match the injectors to the ecm(say a square) will that work or is there more to consider? Thanks.

Dont get to hung up on it . My missmatched ecm works great .

Thanks. From info I'm getting has to do with matching tolerances on the injectors to avoid too rich or lean on the fuel map. I've got a boon docker box and egts so I'll be able to keep an eye on things.
