DIY Guide JB4

[Edmguy11]

Hoping you guys can help me out, I have been searching the forums but can not find a DIY guide for the JB4.

I did however find a guide from allmotor on how to install the BCM here:

Do you guys know of any other guides? I am dropping my car off at the shop to get it installed tomorrow, they said they have done these before. But I want to include a guide of some sorts just to be sure....



On a side note after I pick up my car and use the bluetooth app to select map 2. Do I need to drive for a period of time before my ECU adjusts ?

Lol, your joking right?

You want me to redline my car in 5th.....


Breaking News.... Man caught doing 200 mph on Anthony Henday..... Edmonton Police service has impounded the vehicle with criminal charges pending.....

Lol, no thanks better ways to have a midlife crysis......

You get caught in California doing 170 you're guaranteed a colonoscopy

Note my car is right hand drive, as you are in the States you will need to run the OBD2 connector over to the divers side under the scuttle/wipermotor covers then through the fire wall just to the side of the brake booster shown here:

Everything else is the same- note you can't fit the JB4 to the driveside as the cables aren't long enough to run to the passengerside intercooler where the boost controllers are mounted.

No need to take extreme measures here - such as having to do 4 runs starting at 2krpm and going to redline in 5th - the car will adapt fine after a couple of WOT pulls. Running the same setup.

How did it go?

Ready to add water/meth injection and fully unlease the F10? (its another easy install!)

The only thing missing is the BCM which is the harder part of the install. Definitely doable.

Thanks for this!

Sorry for the lack of updates, I found out last week that I ordered the JB4 upgrade kit instead of the full kit by mistake. So there has been a delay in getting the correct parts & installation complete.

I decided to do the BMS intake & charge pipes along with the JB4 install.

Hope to give you guys some feedback soon. For the first time ever owning a sports car I have not been in a huge rush to increase the power levels. For me the BMW M5 as a daily driver has ample power stock.... but i suppose it's the silly compulsion in me which needs to boost up the power for the odd day I open her up.

I just hope the JB4 Map 2 doesn't compromise the reliability of the vehicle....

More to come soon....

Look into E85, might make sense to run a couple gallons per tank? Maybe not if you run Meth? Check with Terry at bms or your favorite tuner

JB4 is great- you won't go back to stock once dialed in... then go water meth (50/50) injection, get smoother running, more power and it cleans te inlets and valves so saves you a massive amount of money having your engine dropped and walnut blasted!!

I'll try and get a picture up (for 13M5F10) of the actual routing of the JB4 wires to the interior.

I finally got JB4 + BCM up and running. I'm currently having the car adapt
