@Bsbs I decided to not exhaust any more energy on removing the speed limit on my Yukon and went with an overhaul of the power electronics all together.
I have not posted in a while and have been pretty busy DIYing. Here is my new setup:
Phaserunner by Grin Technologies (Dimensions 99mm x 40mm x 34mm)
The voltage range is from 30v-90v and can handle up 50A from the battery. The cables are long for a diverse setup but I checked and it can fit in the nook where the shipping controller is located. I decided not to do this since the controller is programmable and must get "tuned" to the motor. There are lots of settings and I am still tweaking them so hiding the controller would be a pain. Really awesome controller that allows the motor to start using the hall sensors and then run in sensorless mode after initial feedback from the hall sensors. Of course there are speed settings and many other fun settings like injecting field weakening current that can pull increase the motor's RPM without a lot of additional current. (Speed boost!).
I also added a
Cycle Analyst (CA3-DP)
This display has too many features to list. I recommend installing the new firmware to get the benefit of using a potentiometer and digital input to control power or amp levels along with adding PAS level functionality.
Here are few pics of my latest setup:
Hard to see but I swapped the rear freewheel to a
DNP Epoch 11-30 Freewheel to stay in cadence at the higher speeds I am able to achieve now (33mph!)

potentiometer (assigned to control overall power level), digital aux 2 button input (I have it assigned to control PAS levels) and my
Lifeproof Bike Handlebar Mount for my iPhone 7+

720mm OUTDAD handlebar,
Ergon GP5 grips and
EM3EV Power Switch with horn button:
Close up of my
48V Uxcel horn This thing is so loud and sounds like a car horn! Must have if riding in city traffic. I wired it up to the switch with a 20A in-line fuse just in case. Only supposed to use 200mA but you never know.
I'm waiting for my
YITAMOTOR 36W LED spotlight, I mean headlight to arrive so that I can mount it to my handlebar. Got tired of barely seeing the road and cars seeing me leaving late from the office.
If anyone decides to take on such an upgrade, definitely invest in a JST kit like
this. I had to swap quite a few connectors for fitment and wire routing. I also purchased the
Bikehand Pro bike stand along with
Feedback Handlebar holder.
Lots of information so my apologies but hopefully if anyone is looking to overhaul their Yukon this may help. I will post pictures of the stock Yukon controller connector map soon for anyone interested. I also noticed that the on the stock controller PCBA there are plated through holes which resemble programming pads so I may try and see if I can adapt a harness to see if I can figure out overriding any board level programming now it's just collection dust. I will obviously share my results.
Depending how the second half of the year looks, I may take the battery apart and replace the cells with higher energy density cells. Unfortunately the cells will be proprietary to the company I work for but may be able to recommend some "equivalents" that are off the shelf. Not sure how much air is inside the battery housing but hoping to fit 2170 cells to really get improved capacity.
