Are you using a PR harness?

If using the PR harness do what I did. No running additional wires or anything.

On the relay connector
The connectors for spot 85 and 86 need to be swapped.
85 should be a green wire that goes to the hobbs switch
This allows us to use the long pre made wire straight to the jb4 controller instead of running a new wire from the signal
+

From that
Cut the hobbs switch off tape off the other colored wire and use the green wire to connect to the Jb4 controller orange wire
And then ground the other wire that was the signal + wire which is now a ground on spot 85


Been runing this setup and it seems to be working, after 15psi the jb4 pi controller seems to activate the second pump and lpfp pressure is steady around 75psi

Hi Guys,

I have purchased the anti-lag chip upgrade as I'm installing the jb4 PI Controller, my Jb4 is over 3 years old. However looking at the installed chip it already says PIC18F24K22? Only difference I can see from the newly purchased item is it says 1231YB8 after it...so do I actually need to swap this out?

Cheers Russ

acording to Terry,
1) For this to work the JB4 needs the latest 24k22 programming on the slave chip. Any G5 board shipped after 11/1/2015 will have this programming already. For older boards you can update it by adding the anti-lag chip on our upgrades page.

from this thead: (post #2)
http://www.n54tech.com/forums/showthread.php?t=28478

Basically, what I understand from this is that you may have the same type of chip but not the correct firmware programmed inside, that means yes you should swap the chip.

the code 1231YB8 is a manufacturer code indicating manufactured date and which plant made it. This chip is most likely from 2012.

Hi Guys,

Would be grateful of some advice? I have installed the BMS PI Controller...as directed on the first page
Black connects to ground
Red connects to JB4 power on green connector
Yellow goes to the BMS data cable #9
White goes to JB4 DB25 harness spot #15 (where meth blue would normally go)
Purple goes in the JB4 small gray subconnector #21 as read from the female side

I have also updated the slave chip and was already running 32.8 firmware. I made the advised changes to my original meth set up..changed boost additive to 0 (guess as its not mentioned in the instructions) and Signal Scale to 100. Also left Meth safety at 2 and Meth Psi at 7, do these need to change?

Is there any other settings that require change as i don't see any flow? Does PI work on all maps? Is there a trigger to enable/ disable PI? Is it linked to Ethanol setup?

Other than meth scaling set to 100, the other meth settings have nothing to do with PI.

All fuel biases need to be set to 50 to start and you need to have sufficient injector duty cycle for it to show up in the logs.

Stuck on the same situation. Running Map 7 and seeing no flow on meth in the logs and both bank trims are above 40.

Like me I see you were running meth prior to PI...I queried with Trebila and he advised me below, although I haven't tested yet as I have still have a small fuel leak on the T from the fuel line which needs resolving, but worth a shot!

set meth trigger = 1,
set meth safety = 3
set meth scale = 100

Terry/ Steve...when selling these products it maybe a good idea to include the D-Sub extractor or offer it for sale? Ten a penny in the US, but not so easy to get here in the UK and not item you'd consider to be part of a "standard" tool kit?

For anyone who is interested the only company that have seems to have actually produced a decent online document to install port injection is AD Engineering. Yes, if you know your way around a N54 engine its straight forward but so is putting together an Ikea table, but the table still comes with instructions. 1) because it helps the less knowledgeable 2) Because its usually a legal requirement to supply user / installation guides!
Also the JB4 controller install guide is somewhat cryptic "Purple goes in the JB4 small gray subconnector #21 as read from the female side" why not say #8 on the male side you are actually changing? After reading this thread I know I'm not the only person to question?

Do I need to set the external trigger settings in the WMI settings to get PI to work?

Thanks. I already have all that stuff set. Still not working. Im wondering if I need the External Trigger stuff set.

Because the stock connector is a female connector.

If you have installation questions and have purchased a port injection kit from us, you are more than welcome to email us for support.

If you've purchased another kit, then I'd suggest you contact them.

We'll help you with installation of the controller but there are a lot of companies selling kits with little to know support or understanding. When you purchase one of those kits, especially for meth, you should contact them for support as we do not offer tuning support for them.

I know Steve. I was just being a smart ass. I think I figured out my issue. My yellow pin is on 8 instead of 9 on the DB9. All other connections are good. Would that prevent PI from firing? I figured it would still work and just not send a signal to my app screen for meth trace.

On the DB9 not the sub connector for clarification.

No...it would not still work. That pin is the JB4 signal to the controller. Fuelen signal will still show in logs whether it is connected properly or not.

Hi Steve,

Correct this is a EOS rail....but its the JB4 PI controller I seem to be having issues with?

I created a new thread, with pics of the setup to see if anyone can highlight something incorrect? I have taken it apart 2 or 3 times to check the wiring and it looks correct?

http://www.n54tech.com/forums/showthread.php?t=49293

Also rechecked the earth, but again this was located in the same place as the the FSB earth.

In your logs fuel-enrichment is the request from the JB4 to the controller, and "meth" is the reply back (when meth flow scaling set to 99). I see no request and no reply.

It seems you have fuel-bias all set to 0? That would disable PI all together. Default those to say 50 to start.

Thanks Terry,


You were correct, see its idiots like me that can read! I was looking at Duty Bias not Fuel Bias!
