7/11/2023 0 Comments Free obd2 software for laptopg-for-m44/ - It started as an effort to tune M4.4, morphed into a "convert your 850 to M4.4" effort and now we're working on implementing high-speed data logging. Since you have (2) 1998 x70 series, both of which should have Motronic 4.4, If you're into ECU hacking/tuning, check out this thread. M4.4 supports most the 1st group (PIDs 0x00-0x20) of OBD-II data items, minus components that it doesn't have (IE: no 5th oxygen sensor, haha) Whatever the case, Torque and an ELM-327 bluetooth interface is the quickest, easiest way to get live data off your car, although OBD-II by design has it's limits - it was designed for emissions inspections, not real-time data logging or tuning, although some things can be logged via OBD-II. This is mainly because newer cars (99+) use CAN-BUS, and the ELM-327 interface is the easiest (and cheapest) way for a programmer to communicate with newer CAN-BUS cars. Almost all OBD-II software is focused on the ELM-327 devices, or branded devices usually based on ELM-327's or clones. The FTDI cables are mainly used for K-line data.
