I have the old JB4 on my 08 135i I flashed a MHD map then realized that the old JB4 couldn't support it so since its been turned off set to 1,0 Basically turning off the JB4 I ordered the new JB4 G5 it will be here in a day or so. I got just the chip because I already have harness and usb installed im just swapping the module itself. Im running a MHD Stage 2 93 oct tune right now Ive paid for all the stages and fuel options. Once installed can I run my JB4 on any of the OTS tunes together or do I have to use the free BEF options available here?
