Is that e30-e50? Or 30-50% e85?

still trying, the venue we had got too rough to continue,and still meeting with new locations; but the roll racing is packed so at least east coasters have something.

So if im reading this correctly, JB map4. In theory, i could log my 87octane MPG flash tune, and log my 93 octane/tow tune?

Id like to see what its currently doing with the flash tunes, and then from there, decide where to dial in the custom JB mapping for towing/performance

Definitely.. Logging is active on map0. I've had a few flash customers run the JB4 just for logging and to add 1-2psi when on higher octane fuel on the fly.

We've been shipping a lot of them and collecting a lot of great feedback. Working on a few things now so expect a firmware update at some point in the next few weeks.

Sweet--So do the firmware updates just tweak the settings and make the truck run that much better?

JB4_F150_2:

1) Increased torque on map2
2) Back end change to increase analog channel sampling rates. Should not be noticable to end user but may improve smoothness of idle and other aspects of JB4 operation.
3) Adjustment to CANbus logic to hopefully avoid false alarm 04DB code that a couple customers reported.

I've been getting that same code as well.
Snapon scanner says it's a tank vent valve issue.
Ford application pings me and says it's a misfire code.
SP542 spark plugs have made a WORLD of difference in idle quality.

Interesting, if it's a misfire code then I've been looking at it the wrong way. Presumed it was some sort of back end code. Which cylinder is it?

See if the update helps!

Thats the confusing part.
Again- snapon says its crank case vent disconnected.
The myFord application pings me and says it was a misfire code (but it doesn't say anything past that)
JB4 app has no description.
didn't check it with a generic OBD scanner though.


I have a feeling its tune related, as it comes up with cold air inductions and catch cans if you do a little sniffing on the gargles. FRF has some good threads on it. MPT, whipple, five star seem to just tune it out.

See if update fixes it. On a separate note, anyone here have any interest in a "valet" map running less boost than stock?

I have logic ready that runs around 6psi less than stock. Zero boost is a bit tricky though. If anyone wants to test 6psi less than stock let me know.

Just to add 2 cents to this.
I had P04DB code as well. Cleared it multiple times.
Removed the JB4 and it was permanently tripped P04DB. Took it to the dealer and they replaced a PCV under warranty. Maybe related....i dunno.
Emailed Terry this past weekend and he said to try the new firmware. Seem to be all good. No codes. Although, I do get some stumbling at times. Maybe ill try the new cold plugs as well.
Another thing I have noticed is that performance seems to trail off after a couple days. I'm wondering if the ECU is learning what the JB4 is handing it. For example, I can floor it and peels tires no problem after install. Couple days later it wont do the same at all.

I'm NOT saying JB4 is at fault here. Probably my engine/plugs.
I'm just sharing feedback so we can all benefit in the future.

The ECU can't learn out our tuning changes. But it's a turbo vehicle so a lot of conditions contribute to performance changes.

The JB4 has full diagnostics, so record ad JB4 log when it feels slow, and let's see exactly why!

Will do! Also, thanks for emailing me back this weekend.

Hi Terry,

I have a 2017 3.5L EB and I ordered a JB4 a couple weeks ago. The JB came with the _1 firmware, and I rode around for about a week with no issues or codes popping up. I upgraded to the _2 firmware, rode around for a few days, and yesterday I got the CEL and P04DB under normal driving conditions. I cleared it and so far so good. Just wanted to let you know that the latest update didn't fix this bug. This was the first time my truck ever had a CEL or code pop up after a year of ownership. Other than that, the JB4 and app have been great! Thanks.
