Anyone try this on the Manual?

So is 93/94 octane the preferred option? I only have 91 in my area. Anyone turn it all the way up on 91 octane and have issues?

Is this the highest setting?

Looks like your one notch off but I was curious what the difference was it’s set for 4psi at 3 OClock and the 2 ticks past is 4.5psi.per Dave at BM.

“The JB+ is adjustable from 0psi over stock to 4.5psi over stock using the white adjustment dial. Adjustment is made using a small screwdriver to turn the white inner dial. Do not turn the entire blue potor you may damage the JB+. Towards the "max" setting indicates more boost "min" setting indicates less boost. The default setting of 3pm on the dial is ~4psi over stock.”

I’m ordering one for my 6 speed , I’ll report back

Great, looking forward to your results. I've got to finish the break-in on my MT but would love to get a JB in it. Use a dialed in map6 JB4 (E30 fuel) for 7+ years in my GTI and its incredible. Figured it would be excellent on the Supra, but hesitant due to insufficient feedback with the MT.

So I installed it this morning. The connector was tight and took about 5mins of wiggling with the care and fear that only working in a plastic intensive engine bay can impart. Then like magic it popped off simply as if I hadn’t been doing the same motions previously & frustratingly unsuccessfully before.

I took the car out and slowly warmed it up on my fav river drive in the DC area. Of course freezing rain started to lightly drizzle which is a risky proposition in the Surpa in the best of times. Once up to temp, I was able to open it up on some straights and these are my impressions.

For 230$ bucks, I’m not accustomed to actual performance differences. And the Engine / throttle is absolutely noticeably different. Smooth, powerful and more urgent with the JB+cranked up to the max setting (why not right) as I have a fresh tank of 93 plus octane boost just to be on the safe side. If I had to guess the majority of the gains are at lower RPM as the turbo (from a limited sample) appears to get to peak boost (new peak?) earlier opposed to a more gradual and linear climb in the OEM setup. You really feel the extra push early, by 7000 rpm it feels pretty similar to stock-ish. there may be some over clocking of the turbo with usable extra boost making extra HP ( torque efficiency) up at the very top but it isn’t earth shattering. The difference is the boost shove coming quicker and harder with what feels to be at a higher total level.

observations:
-No check engine lights

-Semi difficult to tuck the box up under the engine cover. The closest to the box snap grommet popped up after the drive from tension

- not a big deal but production of the JB+ made it so when I plugged in the box I had to 180 degree twist the opposite side connector to get the orientation of the plugs to line up which used precious slack of the device which made it harder to find a nook to leave it. This is the main cause of the engine cover fitment issue. This also puts twisting tension on the wires which could affect solder joints down the road as heat and Engine vibrations cause wear and tear on the box.

-I will eventually put an intake of the car as well when Dinan list theirs. My guess is the lower restriction air flow to the turbo combined with the over clocking will pay compound dividends in both sound and urgency. Considering the car is really fast enough from stock for this old guy, it is more about experience, personalization, and sounds to me. The low risk and cost of this device with the effect being the exaggerated initial rush to peak torque make it a bullseye for me. I’m happy and will follow up more when I get some more mile on it.

Nice to know it works for Manuel and for the price/performance it’s win win! I wonder how this will perform with 91 since that’s all I have around me?

more boost equals more chances for detonation so I would recommend a quality octane booster or maybe leaving the JB+ in the default position. But I don’t have any data to support that compared to the Supras tolerances

that said the 6port engines with their lower compression can most likely handle it fine either way since the advertise additional boost of the box is relatively minor. It is the electronic equivalent of putting a smaller diameter supercharger pulley on a car a leaving the stock fuel injectors and ECU to rebalance the mixture. Most likely the worst case is the ecu removing some timing which would be counter productive and defeat the point.

little torque bumps go a long way with the 6speeds lower drive ratios.

how did you install it on the MT? Im trying to figure out where I can get through the firewall, how did you do it?

~ the clip release was a bit of a process to figure out but I didn’t have any issues with tucking the module under the engine cover. one would never know it was neatly concealed. money well spent and you can indeed feel the performance difference!

Jb+ is different than the JB4. JB+ doesn't require going through the firewall.

Posting just to let folks know, the clip with the white tab you need to disconnect to plug the new unit in to that everyone generically says is difficult and takes wriggling: after pulling the white tab out SQUEEZE the white tab downwards and it will release very easily.

I used these threads for reference prior to installing and also struggled prior to finding that out - cracked the plastic housing around the wires super easy the second I decided a screwdriver might work.

Are there any other tricks to it? Definitely squeezed the tab down and spent 20 min trying to get it off with no luck till my fingers couldn't anymore ? Think it would help to have the car warmed up beforehand?


UPDATE: just use an angled pick to lift up the connector from the back while you squeeze the tab and pull. Idk how people do it without a pick but I got it first try with one.


Test drive complete with the dial all the way up. Yes it works fine with the manual. I had a weird power delay in 1st gear once but couldn't recreate it after 10 more tries. Probably ECU still was adapting to the piggy back. No joke this car felt as quick as a G80 M3 I've driven. Gotta be the best bang for the buck mod, period.

Did everyone buy from burger tuning? Any resellers on the forum?

Will this module work on a 2023 Z4?
