JB4 - @!#?@!ing (The Imortal words of Qburt)

[Chris71]

Just installed yesterday,
Look, you could do nothing to this car and it is a beast and way fun to drive! If however you plan on doing some mods this should be on your list!!!
HOLY COW!!!!!!!!!!!!! The torque gains are amazing, specially when rolling and at speed. Huge difference in feel!! Forget 15hp here or there, this upgrade rocks!
I'm running:

JB4 map2
Injen Intakes
Ultimate Performance intercooler upgrade
Catless secondary midpipes from ARK
Race Chip XLR throttle controller on sport+ mode
Atq collar kit

If you are considering a chip get this one, lots of guys here to help you out and crazy power with the 3 additional PSI on map 2!! Totally worth the money!

I am! You know I held onto it for past 2-3 weeks. I had that noise issue that thought was originally a big issue, the the level of my paranoia rose from researching and trying to track it down, sent two BOVs back, then thought was a wastegate or turbo issue. Had the issue for two months and had lost confidence. It all turned out to be the stupid worm clamps on right side intake!! Replaced them all with stainless tbolt clamps. Car instantly became fun to drive again, now with the JB4 just insane lol!

What gages do you like to run?

Are you just running the factory plugs @ 0.026?

I plan on getting the JB4 but I'm worried about spark blow out from all the reading I've been doing on the JB4.

 

[Chris71]

No, plus are a must

ALWAYS verify (or have your tech verify) the gap on any plugs you intend to buy and install!

I have the Denso plugs and the JB4 w/ BT adapter on the way. Btw, I did watch the install video and it seems straight forward. But how does the JB4 connect to the cars canbus system? Since the app can perform datalog and real time monitoring of the sensors, I don't remember seeing any interface with the OBDII and the JB4, especially since everything is located under the hood...

There is an OBDII connector that connects to the car. That is how it is able to read and adjust the values as well as log the runs.

Ah ok. Maybe I somehow glossed over that step in the install.

Package came yesterday evening, took me about 2 hours to install the plugs, the JB4 and the wireless kit and arrange it nicely. Running that OBD2 wire through the grommit was such a pain but I didn't need to remove the ECU at all to fish it out. I just used one of those flex claw pick up tools and grabbed the small square harness piece and pulled it up.

Also, for the plugs, you don't have to remove the intake plenum to get to the center plug on the passenger side as long as you have a u-joint and a variety of extensions that allow some "angle" or swivel. Wasn't bad and saved time.

Also, I didn't know at the time but the short black wire and long black wire next to the JB4's OBD2 connector are for the O2 sensors to control fuel. As far as I know, it works without them connected but if connected, gives you more power and the JB4 more control. I'll be doing that this weekend.

I was a little salty I had to spend another 27 bucks for the JB4 Mobile app but I had no choice if I wanted to use the product to it's fullest. Connected easily and everything worked as advertised. Map1 is a nice little bump but Map2, wow, my rear tires aren't going to last very long. This was well worth the money.

I ordered a magnetic phone holder for the dash and some nicer USB cables. Being able to monitor IATs, oil temps, boost, etc. and change maps on the fly through the app is awesome. Too bad it can't integrate with Android Auto and display on the center screen.

I tried datalogging some runs but nothing captured for some reason. I'm probably just not doing something right although it seems straight forward.

I am running my factory NGK plugs @ .025 and have not had a single problem. Running the JB4 on anywhere from map3 to map 6. Flawless.

Welcome back @MurlinatoR, haven't seen you for quite awhile.

Hahahahahaha Hey bro! Happy hump day!

Yeah, It's been crazy for the last 6 months. We have huge construction going on that's got everything upside down and the new Telluride has had every bit of spare time that I had consumed. LOL
