JB+ dial settings?

ruczko · 04-26-2021, 12:35 PM

Hey all, trying to understand each of the dial settings on the JB+ and how that translates to +/- PSI.

The default (12 o'clock) position, what PSI is that and what do you recommend for good power delivery for the B48?

I have mine at 3 o clock. I think that is about 3 psi.

Was that the default position? I thought that was 12...

Once the ECU gets adjusted, 3 o clock feels perfect. Had it off for a week and a half before getting it serviced, and it was noticeable. It feels pretty smooth, but there is a little shove at 3k rpm that isn’t there without JB+. Isn’t drastic though. I also don’t push my car hard frequently, unlike some of the hooligans around here 😂

Jerky in Sport+ at low speeds (as you would expect), totally normal in comfort. Definitely nice to have the extra kick when you floor it. I also left mine at the default position.

Does this void the warranty if you install the JB+? Do you remove it before you take it in for service?

Lots of talk on forum absolutely it this. I remove mine before service, never had any issues. If they want to look, I’m sure they could find evidence of use. Caveat Emptor.

In my opinion it is invisible from ECU side.
So shouldn't void warranty as long as it is removed for services.
