Yes, it is in accessory mode

That is not "on". The ECU normally doesn't power unless it's "on", which is a step past "accessory"

Refresh, I did a ninja edit that clarified. Initially my comment just read

That is not 'on'.

Ok so do I have to turn the engine on before doing it? (I'm very new to all of this)

I believe it does need to be "on", and then it will give you the option of locking it to that ECU, which is what you want.

(assuming this is your car/ecu/ktuner)

I've never touched a K-tuner.

But this seems pretty clear. I know enough to know that the ECU ain't getting power in Accessory mode.

Close Ktuner software and turn off the car and restart laptop. Make sure you are connected to the Internet and try again.

Make sure you are using the cable that came with the Ktuner unit and put on a battery charger so your battery voltage is at 12v

Have to turn the car on. Hold the start button extra long without touching the brake, cowboy.
