Ranger Mods

Hi,
i have an Obdlink MX Wifi, red Version. I can connect via iOS and Forscan Lite to the adapter. It works fine. On Windows 10 with Forscan i can also connect to the Obdlink. I can start some Service Precedures and connect to BCMII with the „asbuildin“ Menu. But i can not connect to BCMII with the Main Menu(pre defined items). Everytime i got an error „Loading SBL failed“ after loading Block 5/5.
It seems like an timeout problem. Are there some special Seetings for the MX Wifi on Windows 10?
Any other idea?

Load the IPC instead.

Do not change as built code or you will kill it.

IPC is a back up of the BCMII on a PX1 or the other way around so this should get you up and running. I have found some of them to be corrupt before and loading the IPC was the work around.

So try predefined on IPC and let us know. You can only changed predefined items in that list on a PX1.

Thank you. I will check it tomorrow. I only want to deactivate the BMS. In PX1 the BMS stop charging the Battery if SOC is on 80%.

I try to connect to "IPC (backup)" but it dosn't work. Some modules crashed and the BCMII wants to be reset so that i lost the consumption data for example. I cleared all the errors in the control modules.
Then I try out a simple USB interface with MS / HS Can Switch. And I'm happy, it works!
I disabled the BMS and drove a lot of kilometers. The battery is charging with 14.6V constantly, i stopped driving if battery has 86% SOC!
Thats verry good.

Did you know the difference between v_batt_bcm and c_volt in FORScan?

I'm wondering if your connections settings were all correct in Forscan then? Anyway you have resolved which is good.

So how did you disable BMS in px1 with forscan please ???
