Brief Check Engine Light

I installed a T-Max tuner a couple of weeks ago. On start up my check engine light stays on for a few seconds then goes out. It did not do this before. The bike runs great, in fact, I think the auto tune is still making improvements.

Has any one else experienced this? I think I might be just picking a scab that should be left alone, but there is so much information here I had to ask.

The engine light going on for a few minutes then turning off is a sign of a historic DTC, check your DTC and clear the code you can do this the conventional way or link up your laptop and check for DTC through the T-Max program. Linking up through the laptop you will see if it is a historic DTC or not and you can clear the DTC through the laptop, make sure you scan through all 4 DTC pages before clearing DTC when using a laptop.
