B58 JB Plus Quick Install Tuner ....

[zrk]

No prob, I'm super new to this platform too and have just been trying to learn as much as possible.

Unfortunately I don't think you can do logs on the JB+ unless you get one of those OBD readers. (Experts feel free to chime in here)

Any reason you don't want to get the JB4?

JB+ provides no logging.

This will be my step in the door. JB4 might come next!

For sure, honestly I say go for it!

I ordered the Jb+ can't wait to get it and install it

I will echo this sentiment. My initial impression after about an hour drive after installation is that it definitely pulls harder. I could feel this mostly when initiating a pass when starting midway up the tach in 3rd, 4th, or 5th gear. You can feel the boost build and the car just whips you around whatever you're passing. So, butt dyno approved, but will reserve full judgement until I spend a bit more time with it - apparently as the car "learns" with the new piece in it, it should only get better (just what I've read - no idea if it's true). For the money, until a full unlock for the untunable '21s are available, this seems like a good upgrade.

Did you leave the JB+ Factory settings ???

Negative! I turned it up to the highest setting.

 

[CarGuy11]

Is this the highest setting?

The added boost indeed aids in breaking the rear tires loose from a dig. Just enough added hp without making it useless out of the hole. Money well spent! Still at factory settings.

Just picked up a JB+ myself. Ran my stock baseline 1/4 times and will go back to the same track and see how the numbers differ. I'll report back.

For those interested.

Before JB+ my best time was 12.2 @ 117 (bone stock, lowering springs only)

JB+ with dial left at default 3 o'clock position
Best time was 12.0 @ 120

Same track, slightly cooler temps. Mph with JB+ was consistently 120 so there is definitely a power increase. All runs were done with a light brake stand, 1700rpm, no launch control, TC left on, amd 60 foot was consistently 2.0 / 1.9

Our damm launch control is so unpredictable.

It always surprises me to see 21’s trapping 115+ stock and then see tuned 21’s struggle to even get where you are stock.

My stock 21 definitely doesn’t feel like a 117mph car :/ But I should probably try to find my draggy and find out.

Why does that surprise you? Genuinely curious. I know it's a sliver slower to 60mph but I thought it made that up in the quarter.

I ran 117mph pretty consistently. 115 to 117 depending on launch. I've never driven a 2020 but I suspect that they feel more torquey. My '21 feels like it starts to pull in the higher rpm range and then just keeps pulling to the end.

Needless to say. The numbers bone stock were on par with pretty much every magazine article out there.

Ok received my JB+. Finally had a day to install and drive my car around. First impressions so far have been positive. Very easy install. No check engine light and car feels like stock until you stomp on the gas pedal . Very Happy with this mod and can't wait to drive my car more. Also its boost weather now and with 93 octane its going to be fun I have not open the JB+ to set for max boost

I saw on the BM site that the jb plus can’t be sold/shipped to calif. Any cali folks have an issue ordering?
