Wheres the best place for a dyno tach lead?
« on: July 13, 2007, 12:20:43 PM »
I have tried it at the ECU on other bikes and gotten poor results.  Anyone have to put one on before they dynoed thier bike?

the one at the ecu works just fine on the dyno for me and it doesn't matter if it is a Harley ,Busa or Duc.

Do you just to an inductive clamp right to it?  Which wire do you use?  I used a "vampire" tap at the coil wire on the ecu on my FJR and the shop told me they were getting 5000rpm at idle :?.  But if it works on the busa I could vampire tap again or do you just tilt the tank up while its on the dyno?

dyno jet tach leads come in two versions I usually use the ECU (suz is white/blue number 1) you must use the correct tach lead  use the one with the small opening (not the inductive large, actually they both inductive electrically)
