J2534 Passthru Interface
CarDAQ is Drew Technologies' line of SAE J2534 pass-thru interfaces (CarDAQ-Plus 2/3, CarDAQ-M and others), long regarded as reference-quality VCIs for OEM ECU reprogramming. Drew Technologies helped shape the J2534 standard, and CarDAQ devices are validated against many manufacturers' OEM software for reflashing, module replacement and coding. Newer CarDAQ units support multiple simultaneous CAN/CAN-FD channels and DoIP for late-model vehicles. Independent shops and tuners use CarDAQ to run factory reprogramming portals and third-party flashing/diagnostic tools that rely on J2534. Drew Technologies, now part of Opus IVS, also provides VCI Manager software to update and configure the hardware. CarDAQ is a common professional choice where broad OEM compatibility matters.
CarDAQ handles vehicle communication and flashing; Softechpro Solutions edits the calibration file that gets written, with modules, Stage maps and checksum correction. The two work in sequence, hardware interface then file software.
