This will be great, any sort off time frame ?

I could beta test if you need someone.

From the first post, does this "PI on stage 1 lpfp and up to 600whp" stands true for this? Assuming full e85.

Each firmware revision has a chunk of logic we need to make it happen. It's a complex process and we need to ensure each change is fully tested and functional as we build up to the end goal.

We have a first draft done and need some help logging it. Drop me an email if you're interested.
Hi Terry,

Has any progress been made on this front? I am running 25 psi and winter is coming soon lol.

Is the latest n20 tmap fuel map still as of 12/6/15?

Default Want to install JB4 - 03-04-2016, 10:58 PM

I have been running MHD, will like to reinstall JB4.
My PI has a separate system with separate tank, pump and boos switch.
Do I have to follow install options for the PI if I want to install the JB4?
or just install the JB4 and leave the split second as it is?
Thanks

I just installed the pi kit.
Is there a way to test it like meth(7/5) ???

Hello,
Can someone tell me which values enable and control the PI in the JB4 interface. I have JB4 controlling the PI.

If it's connected to the jb4 the Pi is enabled

The afr bias settings control the fuel flow

Tks. Any idea of what the bias value range represents (0-100)?. Does PI still enable at a specific boost value, based on rpm (which is what the bias is ranged at and doesn't make sense), or a combination of both? Engagement boost threshold value? I am running the ST FW.

Hey Terry,
Could you share some insight on how the jb4 controls the aic and what the AFR bias numbers correlate to so I can tune the PI?
Tks in advance,

I could have sworn I wrote up something. I'll have to look around for it. Anyway higher values = more PI, lower values = less PI, the internal curve is JB4 firmware specific, and you can log the output under "Fuel Enrich" in JB4 logs.

So I'd set AFR bias all to 50 and look at the parameter in logs to get a feeling for the algorithm. Then raise it in areas where high fuel pressure is crashing if needed.

I'm running this Port injection kit without a JB4. So once I load the N20 map on the AIC controller do I need to make any changes? Is it "Set-it and forget it"?

Default JB4 integration - 03-14-2016, 09:08 AM

Terry-I have a separate setup for the port injection with an independent tank with pump as a secondary for the port system. Will this setup be a problem to do the integration with the JB4?
Also does the SS goes higher than 16psi? or need a new unit for it to go up to 26psi?

The JB4 controls port injection flow. If you have a separate tank we'll have to disable the JB4s low fuel pressure variable for you otherwise it will be compensating IPW for the primary system while you're running it off the second.

After it's all installed and running just drop me an email and I can send the firmware.

didn't realized JB4 integrating PI was also controlling the IPW of the lpfp.

It's not, but it has to read the low fuel pressure and compare that with boost pressure, to calculate injection pressure. This then factors in to the PI injector pulse width.
