ELM327 I use, no modifications on PCB. In device manager it's shown as Prolific USB, VID_067B PID_2303. And although label says v1.5 it's 1.3, works as regular 1.3 or high-speed 1.3 in MES without problem

Hello,

Did you manage to sort out the issues with the ELM327 ODB adaptor. I'm having issues when on high speed mode required for the ABS connection i keep getting times outs.

The windows adaptor is set to 38400 baud and 1ms latency timer, it works ok on standard mode just not high speed.

I've got a Proscan Automotive ELM327 with is the modified version for multiECU scan, does this sound like the same issues you had please?

Currently i cant drive the car as breaks no longer work after proxi alignment procedure.

Thanks

Mike
