US Shift Quick-4 Trans. Controller install on an E4OD
Has anyone on here installed a US Shift Quick-4 Transmission controller on an E4OD?
Would love to hear any tips and tricks to help the install before I start...

I remember that the diagram that US Shift has for an E4OD is useful, that and a Haynes or Chiltons manual for wire color designations when you start making terminations into the factory harness. For several years I used the factory ECU to control the transmission and the XFI run the motor. However, really like that I can make tuning changes on the fly instead of pulling and reprogramming a chip.

Ah! That's great! I've got both the Hanes and Chilton manuals for my truck, so I'm sure I'll be able to put those to good use! I'll definitely take a look at the US Shift E4OD diagram as well!
I figured that if I was going to a standalone engine controller, that would basically nullify everything the factory ECU did, including controlling the transmission.
Do you mean to tell me that if I were to remove ONLY the factory engine wiring harness and hook up my new ECU in it's place, that the transmission would still operate properly if the factory ECU wasn't getting any inputs from the motor?

That's what I thought, just wanted to confirm. There's a reason the US Shift kit needs a TPS Signal.

Blurry had Fast XFI controlling the engine,and left the the Ford ECM in place to control the trans.
You'll like the Quick 4,I've had them in 2 trucks,no complaints.

The factory shift/lock schedules and tables I've used for tuning purposes, just have throttle position and vehicle speed as references. There are some shift tables that use RPM, however, I have found that the RPM's are set so high that the VS/TP based tables take over because those conditions are met first.
If you open up Shiftware, you will also see that that the upshift and down shift graphs are TP vs VS based. However, the converter lock schedules are RPM vs TP vs VS.
