Re: 6.4 High Idle Wiring
ZeroOne I think your right! It's a misprint.
Every post I've read has had the same result with the BCP wire.
Starts at around 900 rpm.
So, I decided this morning to try it right after start up.
It did for the first time, run up to about 1250 rpms.
Then it slowly lowered down to 900 rpms.
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".
Heres what the Bulletin says.
Typical SEIC Sequence for TorqShift™ PTO:
Initiating SEIC by applying battery voltage to the SEIC-PTO wire immediately commands the PCM to first look for
enabling conditions, such as vehicle gearshift selector in PARK, engine at base idle speed of about 650 rpm, etc.
A complete list of enablers is provided in the "SEIC Enable/Disable Conditions" section of this bulletin. Once
enablers are satisfied then the following takes place:
1. Command is sent to boost hydraulic line pressure in the transmission about 20-30 psi, which is used by the
aftermarket PTO supplier to hold their PTO clutch.
2. Command is sent to use a unique torque converter lock-up schedule for stationary PTO.
3. Command is sent to increase engine speed to 1200 rpm default, or a target speed using a resistor.
4. The low-side driver circuit changes from open-circuit to ground. If the up-fitter uses the circuit wiring offered
in this bulletin then this will provide battery voltage to the aftermarket PTO solenoid to engage the PTO.
5. Engine speed increases to the target, the torque converter locks at 1200 rpm, and hydraulic line pressure
increases with engine speed to a maximum of 150 psi at 1200 rpm.
