Ricoo, Is this the JB4 upgrade kit? I'm trying to figure out what will the kit do with the existing stage one piggyback Do they increase the horsepower and torque as well?
Got the JB4 bluetooth connector so i can monitor readings, perform data logs and change maps on the fly.

Map 0- JB4 disabled
Map 1- +4 psi
Map 2- +5 psi
Map 3- user adjustable boost
Map 4- Stock tune w/ JB4 datalogging
Map 5- +6 psi
Map 6- Boost added by engine speed (RPM)
Map 7- +7 psi
On page 197+ I have some information posted about the JB4. The production model should be identical to mine since I was the beta tester. The JB4 hasn't been dyno tested to see its potential, but once BMS makes it fully functional then I would hope to see them test it.

yea green & brown wires, OBD connector, and a BMS S1 without the case.
thanks @sheddy
After running the stock tune and then BMS for some time i was finally able to load my TTI Stage 2+ and the car is running like a champ. I am hoping to dyno my car again since the last results were done incorrectly. As you can see the run didn't start till later in the RPM range.
The JB4 will have more features than Stage 1, but they are both doing the same job. With the data cable you will be able to adjust the boost settings higher with the addition of the downpipe.
One question, does the new jb4 tune anything other than the boost sensors? The boost sensors will only do so much. There's a limit to what you can do in terms of manipulating the sensors. Regardless of if you're running +2 psi or 7+ psi the boost sensors will still only peak 1.5 psi in the lower rpm range and hold 1 psi on the high end. The difference in power between +7 psi is the same as +2 psi. At least this was my experience. It sounds like the jb4 upgrade only really provides data logging
When I tested the BMS we saw an increase in power at +4, +5 and +6psi. I do agree that less is more in some situations and we got the best performance at +5psi (230whp 280wtq) . At +6 we saw a higher peak torque but a lower peak power.

Sheddy how long did u have to wait until u got your stage 2 plus bin after sending the file to TTi?
i already sent mine and its almost 2 days and i still havent get mine yet? Im just waiting for it so i can schedule my dyno next monday...
im a bit exited what will be the car making after spending almost $2.5k this month

There's a 1 to 2 day turnaround period so you should be getting it soon. What other modifications have you done for $2500??

okay thanks sounds good!
full invidia exhaust, PPE downpipe, HPS intake silicone, Lexus F-Sport air filter, charge pipe, turbo muffler delete, aftermarket heat exchanger with Toyota auxiliary pump, innovate wideband, two universal Catch can, and last but not least TTi stage 2 plus with HKS spark plug... i pulled the plug out of no where and did it just this month... broke AF lmao

Very nice!
Where did you hook up your catch can?
What is the aftermarket heat exchanger with auxiliary pump?

Wow, that's an extensive list! Do you have any pictures of the aftermarket heat exchanger setup? This is definitely on my to do list.

Do they increase the horsepower and torque as well?
