Hey all

Looking for some help with TuneECU on my 2023 Rocket GT.

I have a vLinker MC+ which is under the compatible Bluetooth obd2 scanners. The app successfully connects to the vLinker, but fails to connect to the ECU.

Headlight fuse pulled, ignition On, engine off. I have a valid TuneECU license, and the app is up to date.

Any help/insight will be greatly appreciated.
 
Does your VIN fall within the TuneEcu recognized numbers? There was a recent post by Penner that some of the '23 models may not be covered yet. But on mine I have to push it out of the metal shop for everything to work right.

Yep, it was what Kevin described. Just got finished reprogramming the ECU with Penners map and about to take it for a ride. Also it seems that all VINs are recognized now. There is maps up to a VIN and maps for all vins after.

We had issues with this, the run/kill switch had to be in correct position @Nashvegas may be able to remember what/how we set that

If I recall correctly, it was in the down, start position. We figured that out much quicker than the, “you must have the main key fob. The secondary keys will not work.”
