Hi all,
I have just knocked together a 1.3U cable on my breadboard and flashed in the settings from a tactrix one so the line inversions are the same but I cant get a contact with the ECU in my car. It never connects after waiting for INIT in evoscan ecuflash mitsulogger and mutmonitor so something is a lil wrong.
I used the circuit diagram with modifications like so http://yfrog.com/15openport1j taking out the subaru bits.
Also I modified the OBD2 header ports to match that of my car which has the same physical hardware as an evo4, do I need to connect the L line to the debug pin1? I have tried it but it doesn't seem to help I see various places saying leave it grounded to get into debug and only connect K, Ground and VCC.
Is there a length issue with these lines? I have the obd connecting to a 1.4m serial cable with my converter hardware at the end to get the serial to usb... is it worth me putting the K&L line conversion right up in the connector?
Thanks, I realise this is a bit of a ramble but any suggestions would be appreciated as I have rewired it about 3 times now.
