RE: XR25PC Success - Express50 - 05.10.2021
Hello Mister
I have an Express C3G.
I try to read the ECU data to make sure that all devices are OK : the rate of CO is no good
I have tried to do the same as you did : XR25 on PC+ODBII with 4 cable to the odb 12 pins : ground, +12V, K line, L line.
It didn't work.
Are you sure your car is a C3G, because C3G is supposed (as far as I read) to connect with ELM (ISO 9141), not with ODBII.
Thank you for any explanations

Hi.
You better get a renault Clip. XR25PC can't help much, the values were wrong, it only can show errors. Yes I have c3g with a Magneti Marelli ecu. If you have a different ecu you will need to rewire the wires differently as described in the Bulgarian forum. The cable is Vagcom kkl and must use the ftdi chip. it's not using obd2, it's just using the connector and the ftdi chip to change the data to serial communication for the usb.

See my previous posts in the forum, I had to deal with emission problems for a long time.
