Those JB4 numbers, yo.
Is there any way to change maps on the JB4 unit itself? Or do you need to install either the OBDII cable(B/C button changes) or the bluetooth module(app changes)?
I am pretty sure the JB4 comes with the OBD2 cable so yes you would change your maps with the B/C button if you chose not to do the bluetooth module which I highly recommend. Map changes with the app are within seconds and same with sending datalogs. It's 100% worth the extra money for this option.
If you are asking on whether the box housing the JB4 hardware has buttons on it then no. I hope that answers your question.
Thanks, that does answer it for me.
Anyone know the best place (and price) to pick up the JB4? I know it can be purchased directly from Burger but I figure one of their dealers will be less expensive.
The B/C button isn't programmed just yet for the Supra. I have the Bluetooth module and love it!
We may have this figured out. As per my posts on my FB and IG (i know some people don't have either). But we are looking for 1 or 2 cars with the locked updated DME to bring in and pull a read on their ECU. And do a OBD2 test flash on the locked DME. our Partner MHD already have one Successful flash (without the need of unlock) across the water. Just want to test on a couple more cars. Anyone local to Dutchess/Orange County NY able to come in for a test flash?
So, MHD has the ability to unlock without bench flash? When I contacted them last week they advised that it was impossible on locked DME's.
In this part of the auto industry, things change constantly. we are testing. already did one. going to test on a few more before calling it good.
Yeah, I'm sort of weighing theJB4 vs the Titan Protune as a simple bolt on modification - no downpipe, custom maps, 100 octane, etc planned.
Protune looks more expensive, but the JB4 REQUIRES the add on bluetooth device just to be able to set a map and - this brings it's price just over the Protune.
It does seem the JB4 might provide a bit more of an increase, based on some of the charts I've seen here. That, combined with the additional features the BT connection and app allow, might make it worth the difference in price.
You will be SOO hooked on the BT connection if you do it! You don't necessarily 'need it'... you can use the USB/Serial port feature... but it's so nice to just 'change on the fly'... not to mention monitor all your items, temps, boost, etc...
New one to add:
Delicious Tuning has a piggy back: the Power Plug
You guys should really be careful all these piggybacks, just remember none of them iirc have any timing control and relies on the ECU to pull timing and save the engine. I can see now, that there are going to be vendors popping up all over trying to do tunes for these cars, with no knowledge of the platform.
Same thing happens regularly on the BMW side. Just be careful.
