Pan
How do you trigger your Megasquirt Merc?

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

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 wrongLast edited by PanRonnie; 11-01-2014 at 03:37 AM.

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?
