Is this still the case? Are fuel/duty bias set on all maps, or just map 6? e.g. when swapping from e85 to pump, do they need to be set back to 0?

Setting the bias effects all maps

For installing the intake manifold, I know we use bmw oem gaskets on the pi spacer but do we also use oem bmw gaskets on the intake manifold for when it mates to the Pi spacer?

Yes! You'll need a total of 12 gaskets. The PI kit comes with new ones that will go between the PI rail and the block.

6 O-rings for the PI manifold route, 12 O-rings used for sandwiching the PI spacer plate route.

Hello all, new to the board been reading a lot and getting a lot of great information! I am the proud owner of an F22 M235 coupe. I already purchased a Phoenix Racing manifold, JB4 and PI controller, I easily installed the JB4 along with the controller however I cant find a switched 12v supply for the controller, can anyone direct me to one? also the PI controller has two black wires, is it correct to assume they are both power grounds?

With the help of my tester I found one in the fuse box! Just need to confirm that the dual black wires are both grounds, thanks.

@Dumaurier7,
I believe there's only one black wire coming from the PI controller as indicated on the sticker that comes on it. Are you sure one of the wires isn't a really dark purple as indicated on the same label? One black wire is ground; the purple is rpm signal input. Did someone modify your controller and change the colors?

Edit: Just Googled BMS PI controller wires and saw that there is or was and older model box which had two black wires and also two yellow wires. Perhaps you have and older model controller box?

Thanks for your response, the controller was listed as an N55 F22 chassis controller, there is 1 yellow wire, 1 red wire, 1 purple , 1 white , 1 green(I think, it’s already installed in the Jab4 harness) and 2 black ones. There was no sticker on my box when it came.

@Dumaurier7,
Here ya go! I found it on the N54 PI section on this forum. Sometimes the info you need is scattered around. Check out post (#4) from Steve@BMS/Fuel-it!:

Thank you ! I also did some more checks and realized that the injector harness only works properly when both wires are grounded, if only one of either is grounded both pins of the injector harness sees 12v, connect both ground wires and one pin goes to 0v whilst the other stays at 12v as its supposed to! I also realized that both wires were supplied with a spade fork connector already installed whish suggests that they are to be connected at a bolt. Now that my JB4 and controller are installed I am patiently awaiting 6 brand new ID1050X injectors and the fuel hose then ill be ready to install the whole system.

Yes, you will need to ground both of them.

Meth scaling is set to 100.
Firmware is N55_ISO_17_5 I believe (latest). And yes the chip was updated to 24K22.
I am trying to decipher my first log Just to clarify, the Fuelen and Meth signals referred to are represented numerically in the logs, correct?

Yes. You can post the CSV file for us to help evaluate as well.

Thanks for your reply, I am just only testing functionality of the electronics for now, once I install the manifold with injectors I'll post a log. Question, is it normal to be running lean when stock and on map 2? I have intake , exhaust and intercooler upgrades.

All the electronic stuff are functioning as intended, I have posted couple logs in the log section if anyone is interested. Now I am looking to experiment a bit with WATER only CP injection! Ow I have read it here a thousand times that PI and WI don’t play well together, it from my yeas of experience I saw them work perfectly together so I wanna give it a go.
I already have a 200 psi pump and a solenoid valve, will. E using a small 60cc nozzle downstream the intercooler. My plan is to use the output from the PI controller to switch the pump and solenoid via relay. My Question is what are the methanol settings supposed to be at to get this to work?

You have an FSB and PI controller connected to your JB4?

Hi, I do not have the FSB just the PI controller for now, I’d like to get a basic set up running and evaluate its performance before re I spend any money on controllers. This is why I’m asking if the trigger wire from the PI box can be used for now instead of the trouble of a Hobbs switch.

You want to use the trigger wire off the PI controller to turn on the methanol pump?

You can do that, just make sure you have a relay in between. Not sure how well it will work though.

It's an auto trigger that turns on when PI turns on. You can't really adjust it.
