	Bosch _UC and _UM Maps « 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.

Whose checksum tool are you using?

Yes, you shouldn't have to alter them, but you should not be having issues with checksums.

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
