Default evoscan cable

Some of us like to butcher our wiring harnesses, so we can't use the evoscan pnp unit
My FTDI 3v3 won't connect anymore, so maybe it went, or maybe it was the wrong voltage level all together?
my question is:
rs232-3v3
OR
rs232-5v

thanks

This might apply to you:

I had an issue with intermittent connections with the Evoscan cable connection to the stock wiring harness on a car.

I relocated the OBD1 connector and spliced it in right at the ECU. I had no issues after that.

Having issues connecting with this cable..
wiring directly to the ecu at the plugs, and grounded to the chassis.

It connects, calls the ecu id 00000, and autoretrys. Any idea?

You trying to read a burned chip or the stock rom from a chip on the board? You might have a bad chip.

Maybe the handshake or ecu id data is corrupted?

Probably just a cable problem though.

What's the ftdi part number you got?
