Re: 6.4 High Idle Wiring
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Realtyman</div><div class="ubbcode-body">So my next question is. If I added a potentiometer for the BCP wiring setup, and had it set at 1200 rpms. Does the transmission commands run the same as the instruction say on the Ford Bulletin for PTO wiring because of the rpm value.
(IE) Lock torque converter ect.
I would think it wouldn't therefore the purpose of both wiring setups but not sure.
"Not wanting to put any extra wear on the transmission than neccessary".

Are you reading QVM Bulletin: Q-162?
My understanding is that the PTO_RPM (orange/yellow) only works with the PTO strategy. The BCP has its own automatic idle strategy based on battery voltage and current draw. BCP also does not lock up the torque converter, to my knowledge.
While it's true that the document specifies 1200rpm as the minimum threshold for the TorqShift to lock up in PTO operation, I doubt that it does so automatically based on RPM alone. The BCP strategy will allow for rpm's from 900 to around 2400rpm, but that doesnt necessarily mean that the TC locks up as it passes 1200rpm.
As for added transmission wear, I cannot answer that with anything other than an opinion. It's definitely a valid concern and I'd like to know as well. It looks like it just boosts line pressure by 20-30psi and locks the torque converter.
