Hi,
I hav my E8 wiring harness pretty much all strapped in the car ready to go.
I had my laptop connected to the E8, had it online and was looking at the MAP that was already on th ECU.
I went into ignition and changed it to "Waste Spark" and clicked "apply" and a message popped up saying turn the ECU off then on to apply changes to the ECU. I did that and now it won't come back online.

Any ideas?
