crankcase is stuffed like the thanksgiving turkey, lol! you can never have enough power, so a lil more torque never hurts. i'm not running a bleed system, this engine was patterned after the 2.5/260/280 and they don't run a bleed system, alot of it has to do w/ where the fuel is injected, and this thing doesn't have any fuel going thru the reeds, so there shouldn't be any puddling issues w/ fuel. they typically use the bleed system to help improve the idle by getting rid of pudled fuel in the intake tract.

i do have it vacuum referenced, that way it does see less fuel pressure at idle

the problem gary is the early engines only used 5 v reference supply to the tps only- it doesn't daisy chain around the engine like the newer 3 litres, so you basically see both wires go from the ecu to the tps only, so you can't disttinguish what wire does what

Charlie,
What makes the difference between the old and new? I am assuming the old style ECU? Not sure what year my motor is as it is made up of several motors, but does have the old style ECU's if that helps.

thanks rick! i'll have to change the wiring. as for your question, the newer style stuff uses a single motorola computer, as compared to the 2 merc computers on your engine, more or less newer technology. pulled the old powerhead last nite and installed the new one, had to change fuel lines and rerig a couple of things, i still have to do the starter wiring, fix the tps wiring and configure the timing before lite off!

The old ECU's (one for fuel and one for ignition) were 16 bit processors. The new style (and the Wolf) are 32 Bit. It's an exponential increase in processing ability. Going from 16 to 32 only sounds like double but it's really able to process 16 times more info.
I love this stuff. Charlie, you need to post pics of it on the mid.
