TrailBeast - are the relays in your system time delay? I have heard of cases where the overdrive keeps switching in and out at certain speeds and I have seen a few articles suggesting a few seconds of delay
Personally I have never had a problem not using delayed relays.
I just don’t hover right at the speed OD engages at.
Every once in awhile it does happen (like following traffic)
In that circumstance I just turn OD off.
I could also readjust the engagement speed on the pressure switch for OD.
OD is currently set to engage at 50mph which I rarely do.
I’m either doing 45, 65 or 80+.
When I go to CA to visit relatives I take I40 over to I5 then North.
Hang that baby on 100 and turn up the music for hours.:D
