Mine is all hooked up bon dont want to risk going wot on map 3 with decent additive without being able to monitor flow or if it even works.. purge boutton on jb4 app not working ?
What meth safety ? 0

If equipped with an FSB from a previous JB4 meth integration you'll remove it.

I am wiring the automotive relay like so.
30: 12v fused power source
85: thick orange/yellow wire
87: meth pump
86: ground strut tower

Is it right ? How about pin #2 on the jb4 db25 from the fsb just pull it out and leave empty ?

Also i am going to run a pressure sensor in the meth line so that way i know the pump is working ?

Yes, just leave that pin. It wont be in use.

Pressure sensor for Meth PI is in the works.

You have to set fuel bias to something > 0 to enable meth! I'd start at all 50 and relog map2.

That's a good start, I think everything is working as intended. I would just get more logs with higher map and see how it does.

Hi T, I presume all this will work on as S55 M3/M4 on PI Meth too? Currently running 2 Fsb for 2 Meth pump (1 pump for PI Meth & 1 pump for CP)

What I need to do will be as follow:
1, Remove Both FSB.
2, PI controllerís thick orange/yellow wire connects to a ďAutomotive RelayĒ then to the Meth Pump.
3, Remove Pin #2 on the Jb4 DB25.
4, PI controllerís white wire goes to JB4ís pin #15.
5, Set Meth signal scaling to 99.
6, logging.....

Is it normal to see trims dip like that from 40 to 8? I guess that's no big deal as low trim numbers mean that additional fueling is working efficiently?

I may have missed, but are there any directions on how to set JB4 meth settings after the install? Is map3 still limited to "Meth boost additive" value of 75 which equals 20psi? What should be done to be able to target more? Use map6? If so, do we only consider map3 as autotune for meth users in lower power levels? And in turn, are meth settings global, will the same setting be applied to every map?

I just think answers to these questions could be on the front page and it would make a good read. Also people can get more understanding of how meth works and what components meth PI comprises from... I know the principle is going to be very close to E85 PI setup, however I've never seen a sticky meth dedicated thread, so the only useful information is install instruction that come with the meth kit. It would be great to have it one place.

F series instructions:

1- Remove FSB, only use PI controller
2- Yes, correct.
3- It should be Pin #3, you can just pull it out or cut wire/leave it.
4- PI white wire will go to Pin #16
5- Yes, correct.
6- Purple signal wire needs to be extended to OBD Molex.

When the trims drop that suddenly it's a very good indication that meth is working! You can see the meth signal start at the same time the trims drop.

If you have a 3.5 bar map sensor it should adjust the additive scaling so you can go higher. That's what I would do.

Thanks Payam,

Just need to be very sure on item 6. How to pin into the obd Molex & into which slot?

Correction, yes the previous Pin 3 removed, Pin 16 & Purple wire are all still the same as previous.

But after logging I noticed Meth not spraying, can I try to use JB4ís orange wire to trigger the Relay instead of using PI Controllerís Yellow wire?

The FSB should be removed all together, shouldn't be in the equation.

Put the blue wire in its place , set meth scaling 60 , FSB should be in equation to take advantage of safety systems and monitoring the meth flow. White cable for PI and blue cable for meth don't control anything, they only monitor, that is why you can only run one or the other.As soon as we see that PI is working as it should, then you can disconnect the white wire and return to the blue wire to monitor meth.

Make sure for monitoring PI, meth scaling is set to 100, to monitor meth when the blue wire is installed, set meth scaling to 60. Keep up with the blue wire then set your meth psi to 4, meth safety to 3, meth trigger to 0, and all your fuel biases to 50 and post a log.

Had confirmed with Terry, not all PI controller will have those Thick Yellow or Orange wires at least mine donít.

I have 2 Meth pumps, 1st pump goes to the PI Meth, 2nd pump went to the CP. Now by adding a Relay (JB4-FSB-Relay-Pump), they worked well for my setup (S55).

A universal 30 amp automotive relay is normally used.

Are those who are running 7th injector in the charge pipe need an additional meth pump , assuming per injectors need 40 psi to run and the meth pump capacity’s is just only 200 psi ?

do we need a single bigger pump or can I use 2 x 200psi pumps (one for the Port and one for the nozzle)?

If we do, am I going to have to upgrade the fuse?
