Figured it out. After setting Option bit 0 (enable/disable), my JB4 would not be able to switch any maps until a 'reboot' occurred. So I set the option bit, shut off the truck and let it sit until the JB4 app no longer connected to the bluetooth module, and then I restarted the truck. Map selection and switching works as expected with this 'reboot' after setting Option bit 0.
Being a SW/Elec. Engineer, I should have though of the first step in troubleshooting .. when in doubt, reboot! With that, all seems good on my end at this point!

shuddering under light throttle -

Good morning. Anyone running into shuddering under light throttle gradually ramping to more throttle? usually cruising and just ease on the throttle easy and seems to stumble unless its in higher boost.

See if you can capture it in a log and post it up for us to evaluate, please.

The graph and the CSV file loaded are different. Does this happen on map 0?

Hey guys, first post. I am loving the JB4 on my Tundra, can definitely feel a big difference. Running 91/93 mix right now as I have yet to empty a tank fully, then will go 93 from here on out. So I have run mostly map1 and some occasional map2. Should I be completely safe on map2 once I am fully 93 octane?
Also, is there a way I can get a boost gauge on the iOS mobile app or is it not possible?
I see I am able to log boost, but I would like a live readout if possible.
I am planning to go to the dyno soon and do some comparisons on maps 0, 1, and 2 and will also log the AFR.
Any tips on what needs to be done to the truck to put it in a mode that is suitable for dyno? And which gear is best to do the pull? Which gear is 1:1?
Hi, have you guys tested the JB4 with the Hybrid version?
Yes, works the same

The car does not have dyno mode, and even when you put it in manual mode and floor it in a high gear it will kick to a lower gear. IT'S very finicky on the dyno and will take many attempts to get a good graph.
I believe I dynoed in 4th gear (5th is too long and would hit speed limiter before going to redline) pedal at about 50% until you hit about 4.5k RPM then you can go 100%. Dyno operator will have to play with it until he gets it right, so make sure you make it clear to the shop and operator that you want a good amount of runs and not just the usual "3"

I had some issues as well. Eventually I got it to click (not sure exactly how but I did) .. but I put a zip tie around it just to be safe. I think a few people have had issues getting the full click in of that back plug.
Got my JB4 installed today and wondering. Has anyone had any issues with the rear sensor plug not seating all the way?
Those connections are a bit tricky but should latch on with some effort.

What fuel additives are suggested to run MAP3? Love this tuner, really woke this truck up.
I am currently running Shell 93, is this safe for MAP2?
Map2 for 93 octane, for map3 octane booster or mixing in some E85 is a good idea.

Just got my JB4 installed and have been running Map 1. I have a couple of questions. The highest octane fuel available at the pump here in Hawaii is 92. Would this be too low of an octane rating to run Map 2 (93+)? If so, is there a way to have a map designed for 92 octane to take full advantage of the fuel available here in Hawaii?
Also I had read able being able to switch maps via the sport, normal and eco mode selector. How would I go about setting that up?
Finally how can I go about maximizing the potential of the JB4 tuner for my truck?
