ECM is silver/bare metal in a black/rubber grommetted mount. didnt see a mini USB port on it...but I'll check it tomorrow. who knows, maybe it's worth a few bucks and I can offset the costs of my carb conversion.

 

Thats the MM ECM. Your stage 2 kit probably was for the 97 and newer MM bikes. That kit didn't have ECM because 97 and newer were map changeable. Most of your symptoms were similar to mine. In goes the Harley S&S ECM, and EFI is awesome now. Carb change over with that ECM might be no better.

 

yea, its a 98...last of the evo's

guess its a good thing that ECM got stripped out then, eh? new ignition (dyna 2000p) is standalone, no ECM.

 

Hey 1997bagger

Recentley had an S&S Super "E" insatlled in my '85flhtc.
Along with new autolite spark plug ~ I was told they burn better and handle high alltitudes better.
Had the gas tank re-coated,cleaned-out gas filter aslo.

And still for the second time had to come home a half hour into my ride with the guys due to: HESITATION,SPEEDING-UP and not being able to go over 60mph on the highway coming home: then picking-up agaiin to regular speed.

What the heck is CAUSING THIS
It seems that when the bike heats-up after a half hour it starts up again
That do you think the trouble is ?

THANKS GUYS

 

anyone had any luck recently finding an ignition interconnect harness? (HD pn 32435-97)

found a company out of holland thats making a "replacement", but havent been able to get them on the phone as of yet (nor do I have any idea how long it'd take to ship it here). are there any other options, other that just buying the Deutche connectors and fabbing my own? (i dont own the crimpers, so it'd add yet another expense to this build)

Tendancies of electronic controls is to start failing under heat and come back into operating range when cooling off, coils can drop a cylinder or have low spark and not have enough spark to fire a load or accellerate and shutoff is the last part, pickup module will just shut off. I was dropping a cylinder and had yellow spark on a cylinder and blue on the other, yellow is weak.

A friend had alot of troubles with his Shovel losing power and shutting off after a half hour of riding, went riding with him and started doing it, bike lost accelleration and finally shutoff, during restart white smoke was present which was gas and a few backfires, clearly obvious and told him it was a igniton problem. He replaced the coil and heard that he is making long distance trips with no problems, is this the problem everytime NO but tendancies is a part of diagnostics. Pull a wire when the problem acts up and should be able to tell if enough spark, good spark can jump 2 or more inches but yellow is a sure sign of coil breakdown

 

Stage 2 with red injectors usually has a Screamin Eagle SE-3 which is the same numbers as a EV-27, the SE-3 will have more of a "squared" off lobe than the stockers.

That 97 carb harness is obsolete except at Harley graveyards, the updated Twinkee carb harness can have a few wires changed to make it work and common in the conversion

 

thats what I suspected. it goes like hell when its running right

you wouldnt happen to know a part number for the twinkie harness, would ya? (i dont have a book handy)
