MPM ECU Tool User Feedback: I'm trying to save a tune file with MPM after I changed it but its asking for credits, I was under the impression that this device did not need any credits.
How to Solve it?
After the data is read out, if you need to modify the data, it must be modified directly on the mpm software. After the modification, then written into the ecu (do not save the data during the whole process, and there will be a problem of no certificate when writing after saving)
