JB4 for noobs (beginners)

No, data is written to JB4 box. You don't need to be connected to the app.

Can I pull out the JB4 OBDII port plug and still maintain my custom MAP-6? I'd only want to do this while tracking to see some other functionality while tracking, such as shift points when I link it up to one of my laptimer apps with video.

No, you need to leave the OBD port connected.

Well, that solves that! Thanks for saving me the headache of losing my sweet tune from Jesse

You won't lose your tune, but the JB4 will not be able to calculate everything it needs to.

Good clarification. Thx! So, it won't perform as intended until I plug it in again... Wonder if they make an OBD2 splitter

They do, but there's not enough juice in OBDII to power both, unfortunately.

Holy wealth of JB4 and OBD port knowledge Batman! I still can take good video and use my XGPS for accurate speed and G's. Regardless, you saved me a ton of time. Thanks brother!
