Title: Cluster data file (or something similar) Post by: Deko on June 15, 2016, 09:31:50 AM Ive been searching for clues past 2 months now (really intensively) but with no luck at all.
Need some guidance or help, i dont event know anymore where to start from or what to explain. I have dumps from audi a4 (-07 B7, TFSI 220hp) engine-bus and for starters i wanted to track down rpm and vehicle speed, but all the hints of which ID's to look for and how to calculate for example RPM are failing for me. My cluster is: 8E0920901J (which seems to be a ghost, cant find anything for / on it) For example, in quite many forums ive found that can id 280 bytes 1 and 2 are the ones that hold RPM from engine, and ive found 2 different maths for calculation of real value Math1: (b1*255+b2) / 4 Math2: b2<<8|b1 EDIT #1: i do realize Math1 without division is same as Math2 When i run these maths in python that parses my logs, i get these values: Math1 - Math2 Code: 399 1399.75 And i do also get values above 15.000.. which makes no sense. Some say A4 2.0 gasoline engines use this ID or that ID, and look for byte X or byte Y and so on, but my A4 -07 doesnt match at all with any other findings that others have... What ive done is: * searched / google like crazy, im spending up to 9h per day for searching (am determined to find at least some clues) * looked over as many files as i could in VCDS installation folder for finding clues for RPM/speed as well other CID's * searched for definition files * searched for dump files and god knows what more. Is there anywhere, something, that might reveal to me ? Either in Audi A4 B7 in general or some specific engines... Also, when i search for dumps or definiton files for my cluster, it seems 8E09209 01J has 0 results on google (except ebay ones). |
