General question for chip tuning expert

[javyb]

Opel/vauxhall edc16c39 has two maps. When reading obd only one of the maps can be read. What data is in the second map that can only be read bdm not obd. For DPF off is a BDM read necessary or is OBD read sufficient

Thanks for your time and answers

For DPF, EGR and tuning obd read is enough. But full bdm is necessary to completly delete a dtc. Other info I don't know. Best regards

the two managment are for various coding : climate cold-warm and others specific country coding....i read always bdm and mod all managment, in this case i can not have problem.

Cowboys make by OBD... :)

I make all DPF on these by BDM only.
