Heres an odd update....try to follow me!
Bike running & missing dead on rear cylinder, as the bikes running remove rear plug wire cylinder is dead,install rear plug wire & pull front plug wire off & bike dies!
Start the bike, unplug front injector & front plug wire & bike's running on the back cylinder!!!! WTF!!!


Almost GOTTA  have a driver in ECM bad!!?

Tried that out of desperation from an 02 ultra with a TTs tune with a hippo build. Bike started & died,wouldnt restart.

Just went & started the bike dead miss on rear after 30 seconds,now i pull front plug wire & bike dies,replace plug wire,startt the bike remove front injector & the bike dies!

@0 minutes ago the dahm thing had a dead rear cylinder removing the rear wire,replace it & pull the front & it would run on the rear , Startys missing on rear,pull the rear wire no change in the engine defintly missing on the rear,replace wire & pull the front injector & plug wire it runs on just the rear!!

I meant a stock one and yeah, can't have security. From what I see at Ronnie's, '05 is a stand alone year for ECMs....don't know why

Found the issue. Compression was even 130/130, 100 psi on leak down 3% leak. A good buddy recommended checking leak down @ 40 PSI & it showed up 20% leak, Lower the pressure the worse it was. Said he ran into this one time on a GM truck & called GM tech assistance,told him they recommend checking @ no more than 50 psi & he found his issue. I found mine.

Interesting reading for my continuing education, only understood parts, but the statement about the lower psi on leak down test was interesting.  Always checked myself at 100 psi, just to make the math easier.  Will have to remember that one.
