Alright well the ecm definitely took care of my spark problem it's bright and huge and will run off pouring gas in tb. Now a new problem has c o me up. I'm not getting an injector pulse from the ground side. I have power at Orange wire I've checked grounds yet again before I put in the new ecm was working and spraying fine, I took a break and thought oooh I know the tps must be off so I checked and it's spot on and also brand new. No shorts continuity from end to ecm all good.... I'm ready to give up
 
Sorry to hear that it's still giving you issues . Did you check the wire harness in the jumble of wires a few members had the same connection that had some type of 3 way split and created some type of problem .
 
I did check wires gonna throw old ecm and see if it will drive the injector, maybe new ecm isn't right. Spark sure is healthy now
 
I've got this same no/weak spark problem on my FE600E from 2000...
Unfortunately no one ever showed me how to use a multi-meter so I'm already a step behind.
 
Well your 2000 is gonna be different from mine. I have kokusan ignition, well so everyone knows I put old ecm in and got injector to work so apparently new ecm is bad. I'm taking it to the dealer where I bought the parts and having them straighten it out. Unfortunately with thanksgiving coming up it won't be ready for the Ozark 100 miler, I will let everyone know what happens
 
Still haven't got the ole berg to the dealer to be mapped will be going tuesday, I've been busy with my two newest editions my ktm 300 and my lol ladies 150r
 
Just wanted everyone to know the berg is back in action and everything new after thousands of dollars. I ended up taking it to shop and having new harness put on i had zero time to do it after being there two weeks i get it back and wiring ran wrong and not charging but running after mapping the new ecu. They apparently moved wires in the rectifer plug and had the all wrong. It is now fixed and running great
