Hi Nick :-)

With the WRX I've tried to do the green light / orange light but I only ever seem to get just the orange light (maybe it's a WRX vs STi thing).

Orange light s on and it's all good but I believe what your saying with the interuption nad clunk that sounds like what exactly is happening when I take off..only when the wheels are losing grip (all 4).

I'll see how we go but it really is odd...

Thanks :_)
