Optimal JB4/BB Flash settings

brewnami · 07-04-2014, 06:54 PM

Question for those running the back end flash with JB4:

Just installed the Walbro 255 kit from SteveAZ and loaded the BB Flash (E85 BIN). All seems normal, but I as I prepare to head out and run some logs, I wanted to see what settings both in the JB4 and the interface values everyone is running.

For starters, my mods are in my sig, but for those on mobile, I have JB4 G5 ISO, BMS downpipes, DCI, ER FMIC, ER chargepipe, BMS 2.3 gallon meth kit and of course the flash and 255.

I see in the DIY, Terry says to set all AFR and CPS values to 0. When loading the flash and updating the interface to say G5 ISO with Flash, I set to map 3 in steering wheel controls, but it says map 6 on my laptop.

I also see a lot of folks are running the 4-2 option as well...

Just wanted to see how fellow members set theirs up with E85 and Meth.

Thanks!

If you run the back end flash, It is best to run option 4-2 because you let the JB4 control all the boost. The map 6 on the interface is refer to the boost table below it. It is to set your own custom map. If you have more questions you are welcome to pm me or e mail me at lukeperformance@gmail.com.
