    Been doing a bit of research on different ecu's, came across this 

    Crank sensors are most commonly of the inductive type, you can normally use the original crank sensor. If your engine uses the hall effect type, MBE ECUs can be built to order.

    MBE write special code to allow the use of a range of different trigger wheels, most commonly 60-2(GM/VW/Bosch), 36-1(Ford), 24-1(Suzuki hayabusa) & 24-2(Suzuki Busa 2008 & other late Japanese bike engines). Other trigger wheels may become available, download Easimap 6 to check current types. 

    A special piece of software has been written by MBE called soft start, this was produced due to known problem with the standard starter motors, that if the battery got a bit low sometimes the engine would kick back on starting and engage the starter clutch. This would, if you were lucky only damage the starter clutch itself, but if unlucky could break off part of the engine cases. Without going into too much detail, the ECU allows the engine to get up to speed during cranking before attempting to start the engine, if the engine does not reach sufficient speed it will not allow the engine to start, so damage can not occur.

    My bike did suffer with starting problems as described above, the soft start sound interesting, but do all other systems do the same?

    So leaning towards megasquirt 3 or microsquirt, Cant make my mind up yet. Just want something that works better than it did with carb on, Is reliable, and affordable. Don't need something with all the bells and whistles.

    So where is my best place to buy from?

    Cheers SRR

    Thanks Arttu,

    Come to think of it, I think I have one already fitted to the existing set up.

    I am possibly  thinking of getting a megasquirt 3, what do you think?

    or would the microsquirt do?

    Cheers SRR

    Thanks Tombola,

    some interesting reading.

    Another option is to get a ecu from a hayabusa or gsxr and have it flashed

    pro's. 1. Readily available 

    2. Quite cheap secondhand.

    3. Manufacture have spent lots of money sorting them.

    Cons.

    Update.

    Rang omex today to see about using one of there ecu's.

    when I mentioned it was going on a bike, they said it wouldn't work.

    Apparently they have tried it but because a bike  goes from a slow turn over speed to say 1500 rpm there system can't cope with it.

    And the other point was about the size of trigger wheel, the larger the better.

    so it's back to the drawing board to make a decision on the ecu.

    Really want to use a motec but to pricey for me, and Cant seem to find any reasonably priced secondhand ones.

    Cheers SRR

    No, it's a draw-through setup modified to EFi with the intercooler added to it

    Hi Marco,

    its a blow through , intake from turbo goes under tank to intercooler, then round the side of the bike to the manifold and injectors.

    Cheers SRR
