    I thought you all were discussing Direct Injection ECUs.

    You need 65v on the injector to drive them, anyone know of a aftermarket that will do this?

    How do you trigger your Megasquirt Merc?

    As I posted earlier, Motec M142 and M182. Not that I have either but data sheet says 90v.

    Thanks barry
    cylinder head mods for that will be project #2, will also look to see if the Motec could drive a etec injector?

    look at the flywheel starter ring
    a 36-1 tooth pattern has been machined there
    near the throttle arm is the hall sensor
    cheapest and easiest way yet

    Very cool so all you need is a 36-1 pattern anyway you can get it and your cooking with gas.
    Well there's something I learnt today

    yes but the cylinder number needs to divide evenly among the tooth number
    36-1 does not work for a V8 two stroke
    you need something like 24-1

    I saw the motec m1 and that's why I asked, at what point does the cost out way the benefits. The down fall with the m1 is first the price is about $6500 for an empty ecu. Then you have to have some one write a OS program from the ground up. Then after you pay that person write the OS program it is their property and you would have to go back to them every time you want to program an ecu. You can see where the dollars add up real quickly. So what I really wanted to know is taking a etec engine removing the fuel and ignition system, buying a after market efi ecu for about 2500, (on the low side for a ignition and fuel setup) installing a efi front half for ????.??, changing the flywheel and stator setup for ???.??. Does it even out because with the dfi ecu you get to keep all your oem fuel injectors and sensors, and with a adoption harness you wouldn't have to splice any wires. Would a $8000.00 ecu be worth the flexibility to modify your dfi engine.

    the etec injector is a very particular one
    the first thing you would have to do is properly diagnose the electrical signal
    then find out if any of the after-market ecu,s is capable of replicating the injector signal
    like you said it can probably be done if through enough money at it
    but that was not the question ( before the cost out way the benefit )
    the ecu,s will already have a hefty price tag and it will not be stopping there!

    now changing an etec to standard manifold injection
    should be possible people seem to do it here
    you can either completly remove the flywheel and install a alternator and alternator pulley wheel on the crank
    or change to old style stator and flywheel but the upper bearing carrier has to be changed to old style for the stator
    second problem the heads
    since the engine was designed for etec injector,s as were the pistons

    installing old style pistons and making sure the clearances add up with the old heads
    now you would be getting somewhere but at Wat cost
    you could buy a lot of fuel for that
    maybe in the future if ecu prices come down and it becomes clearer wat the ecu,s can and can,t do it,s an option
    for now if you want a high horsepower engine which you can tune yourself
    sell the ETEC
    buy a pre 2000 evinrude get it rebuild and possible ported 1998 vindicators are nice
    install any after-market ecu and have fun with it
    at the end of day fuel economy is the not the biggest thing you need to worry about with a high performance engine

    but plz feel free to prove me wrong

    Cant see why you would convert an ETEC back to injection in the front?
    I would be just working on getting a pak to run the original assuming you wanted to modify the engine to make more power?
