Hello and Merry Christmas Since I have access to various software & hardware, the following question to the programmers.Can the SIM271DE20 with the latest software available from MB simply be reprogrammed in the variants configuration with Vediamo from 200CGI to 250CGI? Are all parameters of the 250er automatically entered after the changes (after reset) from the 250er? There are various parameters in the control unit and the 250CGI with the M271.860 has no other control unit keep quiet another engine, turbo, injectors etc. That says EPC! The braking system might have to be adapted, but I will then clarify this if I succeed at TÜV. I am not concerned about the 20hp more power (do not drive my vehicles completely at my age anyway), I would like to have more torque available. The engine was just at approx.86.000km with chain demolition completely overtaken by me and I would have had a second overhauled M271.860 by now. The “reduced performance” engines die without notice far before the 100,000km limit with chain damage etc. although they are consistent like my “MB checkbook well maintained” and always only the original MB 5W40 (MB229.5 release) has been filled in. Of course, the whole is registered on success, so please also no answers from any teachers. Greetings and thanks for your answers (also by PN) Michael
