Engine life is a big, big, concern for this low bucks guy. The dyno jet inertial dyno we use gives us the info we need and exposes the engine to minimal time at full throttle. More data with less motor wear.
WW,
good point on less motor wear on a Dynojet
Dynojet sweep pull lasts 3-4 sec; do 3 of 'em back to back = data at all rpm.
3 4000-11000 sweeps x 4 sec = 12sec WOT
tune - repeat -tune - repeat, etc
tuning can be fast if you have a very competant operator, like JC
dyno operator does tuning adjustments
whereas
FactoryPro, you do steps at 1000 rpm increments, each step is 3 sec+/-
e.g. 4000, 5000, 6000, 7000, 8000, 9000, 10000, 11000 = 8 x 3 = 24sec WOT (48sec for 500rpm steps)
tune - repeat -tune - repeat
tuning is slower, gotta consult bike's AF log, operator just making pulls,
I prefer the owner (me) making tuning adjustments
This is just my experience.
I heavily used those 2 dynos and had very successful results but I am NOT a dyno-smart guy.
