Title: Bosch _UC and _UM Maps Post by: Assoor on August 04, 2018, 11:30:35 PM Hello,
Just wondering about those maps. i always find 2 other versions from the maps in some bosch bins. example KFZW KFZW_UM KFZW_UC i believe one for actual angle and one for monitoring and the other for testing. but i cant understand exactly when then are activated or under which condition. im asking this as i have this file whatever i change the _UM and _UC the checksum always calculated wrong. when i leave them alone they work good.

Yes, you shouldn't have to alter them, but you should not be having issues with checksums. Title: Re: Bosch _UC and _UM Maps Post by: bk56190 on August 08, 2018, 06:12:25 AM Hello,

Title: Re: Bosch _UC and _UM Maps Post by: overspeed on August 09, 2018, 05:12:11 AM Alientech tools can´t deal with checksum on some of these maps (on MED17.5.21 too for example).
If you CKS with WinOLS it recalculate when writing and give you a error (on MED17.5.21 only some time after and only in some conditions), other tools (like flashpro from dimtronic) make it as it should be and work like a charm |
