i'm using an ATG on an r90. i have the rpm at normal set at 1800rpm. however i can't get a higher speed on my idle ups using the aux2 mix on my jr 9x. here's the mix
AUX2-->AUX2 mix(triggered by idle up switch)
idle up 1: +90
idle up 2:+100
on this setting, the speed from normal to idleup1 is roughly the same, but on idleup2 it seems to go down to roughly 1500-1600rpm. i'm aiming for about 1850-1900 on idleup 2. what can i do?
