VCM Lights Stay On After Tune?

I just flashed my 2015 Accord V6 for quicker shifting and disabling the VCM. The green VCM lights are still on after the tune. Do I need to re-flash or is this normal.

Thank you!

You likely uploaded to a tuning slot instead of flashing, which would say Uploading instead of Flashing during the process.

So I flashed the tune and I'm still seeing the green lights around my speedometer for VCM. The transmission feels much improved with quickshift 1 selected. Night and day difference. Is it possible for the lights to stay on after flashing?

I've never heard that before, so I imagine not.

Any recommendations? Everything seems to flash just fine. A few lights on my dash stayed on until I drove for a bit and the tuner didn't display any errors. Is there anything else I need to check other than "Variable Cylinder Management"?

Thanks again for the help. I really appreciate you answering my questions.

Everyone I've asked who owns a 13-17 Accord says they do not have a light, so not sure where you are located to have one. Either way, VCM would be disabled with the disable regardless of the light status.

I am having the same issue here. I have tried flashing with both the box checked and unchecked and the ECO light still comes on.

If you're sure you've actually flashed the vehicle, send a datalog of cruising to support via email.

The green lights does not mean you are on vcm. The green lights are just telling you that you are driving on a a fuel conservative way. You can shutt that feature off . Look at the car user manual
