JB4 Hitting 25.7 PSI!

[PARA90N]

Hello everyone,

Wanted to share my JB4 log and get some perspective on whether this is normal - car's hitting 25.7 PSI of boost using:

JB4 + EWG Connector, on Map 2.
K&N High Flow Filter
Stock Otherwise
3 Gallons of E85, rest 93 Octane.

Car pulled strong during logging from 3,000rpm to redline on 3rd gear without issues. Decided to log because there were moments of hesitation under WOT on the same map sometimes, around 2 out of 10 pulls.

Appreciate the feedback if anyone has any, thanks!

EDIT: Attached log file zipped up, additional comment - car is not throwing any error codes at all or going into any form of limp mode.

@Jesse DaBears is the expert on the JB4 and custom Map6 setups for you.

As for your experience, I've run map2 before and I did notice spikes on boost when datalogging. Getting a custom map6 solved it.

JB4 can try to hit whatever. I'm pretty surprised that you're hitting 25psi on Map 2. Meth says 100%.. does JB4 think you're spraying meth?

I would ask the people who made that device? Not random people

I know quite a bit about JB4, I also know how to read logs. I'm pretty qualified to help, but as someone mentioned above. Jesse is the one you wanna talk to.

Thanks! Yeah I've messaged Jesse and am waiting for a reply.

Thought I'd get some feedback since there's a high number of locked ECUs out there probably running piggybacks.

Definitely no meth. Literally plugged in JB4 and used the app to change to Map 2 via Bluetooth.

New or used JB4? Do you have the latest firmware? Make sure everything is up to date.

Bought new straight from the BMS website.

Make sure you flash the latest firmware. What fuel are you using? I can take a look at your log and see if I can get a hold of jesse. We both got pretty sunburned at the track yesterday, so he might be.. out for the day, lol.

I appreciate it! Log's attached on OP as a zip file. Yeah I'll have to flash update the firmware for sure - was under the impression that it was already on the latest firmware since I just picked up the JB4 unit recently.

Not in a rush to hear back from Jesse; it's a holiday after all!

Guys I have a question, I messaged Jessie about this as well.

I just got the JB4, waiting for my 1200 mile break in period to finish. What kind of map can I use with all stock parts? And what gains am I looking at?
Also I have a AA downpipe (catted) and an intake waiting to be installed. Once that install is complete what map am I able to use?

I plan on sticking to 93 gas.
