2008 Street Bob.
I have to put my stock slip-ons back on for a day or two and show the bike to the authorities. They didn't like my Straightshots.

I have a SERT and a modified version of map 176AE104-A1. The active exhaust is deactivated. The walve opens and stay open once I turn on the ignition.

Ok, so I want to reactivate the active exhaust, but the choice is greyes out when I choose "Program ECM" in the SERT program.

Anyone knows how to deal with this problem?

The SERT program version is 4.7.7. In the upper right corner of the main window ther are two fields...one with green background with the text "CLOSED" and one with yellow background with the text "TC88A,TC88B". I guess the reason that the choice is greyed out is that TC88 don't have active exhaust.

 

I would leave the map alone. What is the worst that can happen? The bike will run rich with the slip ons.

 

My plan is to leave the map alone, but I'm worried that the bike will make too much noice with the active exhaust valve deactivated.

The active exhaust is under the control of the ECM, but it's not a part of the map like AFR and other stuff. It's something you can turn on or off when you transer the map to the EMC. Mine is off all the time. The reason tha the choice is greyed out must that the map is for models without active exhaust.
