User reviews
CEM
Using mainly for CEM and DIM work. very stable and fast tool, no unnecessary stuff.
Really like that I can do most operations over OBD without removing modules👍
★★★★★
DIM
Tested on P2 and P3 cars. EEPROM read/write works perfect.
Finally a tool that gives real low-level access, not just diagnostics.
★★★★★
