Hi

As is well known, the elm 327 with EDF does not communicate if not ssi change the hw.
I have version 1.5, written on the box, but inside ? a 1.2

I tried to remove R4 and nothing

I put R4 and I removed R24 by placing a jumper between pin 6 of the pic and the component U1, but nothing.
Known that before I recognized a vagcom in the com port 4 and an elm327 in the com6. Now only the vagcom on com4.

any advice?
