| Lou,
Hard to say, but it sounds like your PowerJazz is still in APM mode. In apm mode the pj will take the first throttle setting as 100%. So, if you startup at 65%, your other idle-up settings will need to be a lot lower to get a lower than 100% gov'd hs.
If you have tried 'fixed' mode on the prog card, setting hi/lo throttle points this should fix this problem. I found I had to redo this a few times to get this to work properly though. This is a bit of a pain to do since you need to power upeverything, incl your rx,and bring a lead down from it from the throttle channel to the bat plug of the prog card and also plug the esc into the esc plug of the prog card as well. I needed to make a 2-ended lead with servo plug ends to do this.
Once you do this you should be able to hone onto a idle-up hs that suits you. Maybe start with something like 60% Idle-up 1 and 70% idle-up 2, tack them, and go from there.
One thing to keep in mind is that the jazz escs use initial pack voltages to set gov'd hs's so if you have a number of different ages/makes of flight packs, do not expect them to give exactly the same headspeed at a given throttle setting, although they should be close on 10-12s. On 15s, I get +100-150 rpm hs differences. Also, avoid unconnecting/reconnecting the esc battery lead after your initial spoolup since it will then recalculate the initial voltages based on lower pack voltages.
Good luck and welcome to the world of crummy Kontronik instruction manuals! Hang in there, it will be worth it in the end.
Cheers,

... hehe. It sounds like maybe you are you trying to program the PJ like we used to with the old Smile and Beat ESC's. If so, the PJ is very different.
