In order for the Compression releases to operate do you need a tune that supports ACRs or just make sure you turn it on when flashing the tune to the bike?

They are not operating. This is a new build so tomorrow I'll go over the wiring.
I may just hook it up like SS does.

The tune and ecm must support it. But I would think if the option is available,  then the tune supports it.

They must be turned on in the software

I think I may have found the issue. I get power to the releases for 2 seconds when I turn the ignition on. So evidently I wired them wrong.. must have had one too many that night.  :embarrassed:

What year/model bike? Some of the strategies cycle the ACR once at key on.

That's right- ACRs are powered by the system relay ( as well as the fuel pump and coil). ECM uses grounds to control the activation, so verify you attached the other pin to the ECM at the right point (should be pin 15 on an 09 Dyna)
Ignorance is bliss, and accuracy expensive. How much of either can you afford?

Are ACRs toggled on by default in the program?

No- radio button in the ECM settings.

What is the Part number on your ECM?
What cal number are you using?

I know you are not working on a 2017 but read through this thread
http://harleytechtalk.com/htt/index.php?topic=101668.msg1196415#msg1196415

You may want to contact TTS to see if they can help.

I also when through this with a friend on his 2011 Softail using PV and finally got an engineer at PV to state that PV cannot turn on the ACR's on that bike regardless of what the cal says, had to go to the dealer and have it done. Now they work with the PV cal even if we toggle them to the off position in the PV software.

Good luck

Which 176 map are you using?

Crank sensor went bad.
Problem fixed...

Now with the crank sensor not a problem I noticed that sometimes when I start it, the engine has a hard time. Like the compression release was intermittent.
I was PMed by ridgethumper and he explained the crank sensor and it roll (this is how I found out the crank sensor was the issue) I took the ACR wire to the fuse box and moved it to the constant power on with ignition. Now compression releases always work, no delay. Starter spins good and fires with no problems...
Thanks for the help guys. Now I've got to get the heat cycles done
