Ok so 'finally' got around to doing this install yesterday... works a treat. Super quick to do.
Had an EKP2...trying to hold up a Hobbs switched stage 3 twin 450 setup.
Had already melted some wires and part of the battery top distribution block in the past , so it was overdue.
Failing Hobbs, ekp2 and melted wires a thing of the past.
Out with this thing...in the E92 its behind the passenger seat side back bolster.

Then get your speedsty dual relay package out.
Then carefully work off the cover of the EKP
Then using a t10 , undo the 2 small bolts holding the circuit board to the base plate.
Then transfer the Speedsty dual relay EKP over . Note that the heat pad needs to be transfered over. Mine was stuck to the old EKP underside . It is easily peeled away with gentle action and can be placed on the new setup. Remember to note the orientation/pattern, it matches the backing plate, so it's easy to place correctly.
Next replace the t10 bolts and remember not to use force to try over tighten them, they can easily strip.
Replace the cover , there is an alignment groove to pay attention to so the cover lines up. Easy as.
Afix the Speedsty sticker to the case for an additional 100hp.
Now to the car. You will need to access the fuel pump hat. 4 x10mm nuts holding the hat on.
Go into the boot first and feed the wires through to the seat area /fuel pump that need connection to the battery (negative and positive wires are both labeled 'battery') so then you are ready for the next step.
Here you will need to ;
Afix the labeled wires to the positve and negative pump terminal posts. The supplied wires are marked and the instructions are quite clear at this point.
While there , you will note the two wires going to the pump (brown is ground and red/white power in my case) These are originally going into the factory black connector that connects to the EKP. You will need to note them when you plug in the pins for the new wires (in the instructions)
Then battery side. Connect the terminal positive lead and while there , stick in the fuse to the plug. I didn't get a cap for some reason (its small so might have fell out somewhere in packing? I am following up as it's better for the fuse to be sealed up but, its not a big deal.
There is reference to a fuse protected link in the instructions but, no diagram so you might be scratching your head as the fuse is loose not fixed inside.
This is the fuse holder end of the wire.
Below pic is the factory black(flash was on) EKP connector with the two fuel pump wires (brown negative & red/white +ve)
IMPORTANT. This is the view from the "Back" of the connector. The wiring pin configuration on the instructions is to be viewed from the front.
This connector has a top and bottom release tabs which you need a really thin pry tool or flat jewelers to pry from the sides and slightly towards the front (it will flip and hinge from towards the back) These are easy to snap. Then you can plug in the pins in the correct configuration from the supplied diagram. The diagram is viewed from the FRONT not the back(like this picture or where you physically plug in the connectors). The reason I say this is that the picture is confusing but, you definately need to be looking at the font of the connector to get this pin out correct.
Easy done!
Pop everything together again. Get your laptop . Download the Speedsty software .
Power on the car.
Connect to the mhd wifi dongle tick wifi on the Speedsty software.
Verify the EKP
Download and then update the firmware
You are ready to go to settings.
In my case I have disabled the ground trigger option.
The default for the 2nd pump is engine torque of 200nm, this is fine for a standard pump as a tip over point.
I am setting mine to somewhere between 350-400nm, since each pump is a 450.
You have other methods for triggering it too.
Overall the install is just a little more time than an EKP change but, with zero coding required. The kit is very simple and cost effective.
The startup priming time can be configured too.
First thing I have already noticed is a slightly better start on the high E mix, than factory.
Will share more experience as it goes on. But, big thumbs up so far.
