Default Car keeps jumping from map 5 to 4 - 09-17-2020, 02:50 PM

I have a 2008 mspec 335i DCT(we have them in OZ) with a JB4, charge pipe, stage 3 xhp transmission flash, BMC drop-in filter. Map 5 keeps defaulting to Map 4. I bought the JB4 unit used and think I have reset all the settings to default the last owner advised he ran a backend flash.

I am hoping someone could look at the log and tell me if there is anything I have missed or the cause.

I have attached a log;

Thanks

What fuel?

something is definely wrong, you are throwing the Lean safety.

Given the unit is used, I'd flash our OTS BEF for your given mods, just so we know what is on the car.

After you flash the car, ensure that the Tach is set to 4/2

Thanks for the reply Dave, I am just not completely sure what "our bef" do you mean BMS?
Is there a link to the OTS BEF?
