It's a first facelift, so chances are it is a 7202. I can't remember the error, but it seemed fundamental. I had to select what kind of ecu it was and the list didn't give a perfect match. Do I need definition files on my laptop first?
have a look at this thread and it should explain everything i went through to get it to work.

read through it fist before you do anything as i had a cable issue which caused most of my issues which was fixed at the end of the thread, but i think i explained what was required with screen shots to make it obvious for others to follow.
Bye for Now!
Right, there's a small chance it's a H8/539 like mine, which means you'll need MMCFlash. Best get Rich to pop the ECU out and confirm the numbers on the chip.
For reading a 7202, you wanna read it as the following;
And for a 7203 (later facelift) it's the next one down. Also, you'll need the reflashing connector plugged in to read it.
Forgive me my stupid question here guys and tell me to get lost if u want, but could someone explain to me (a simpleton when it comes to cars) what u can do to the car with this, it really interests me to me to know whats going on with the car but all sounds alien to me
again sorry in advance
This cable allows you to reflash your VR4's ecu, or simply listen in to what the ecu is doing. With the right software you can monitor a fair few inputs and outputs on the VR4, just a few:
Air flow, air temp, knock, timing advance, throttle position, battery level, water temp, lambda sensor, atmospheric pressure, individual wheel speed sensors, etc.
You can operate various things on the car, like AYC pump, boost solenoids etc.
You can also potentially reflash your ecu, which can change the fuelling, boost, timing etc or even start doing things like launch control, switchable maps, etc.
