DTC codes after decomp cams installed
Hi All,
Recently installed a set of S&S 551 EZ start cams in the 09 BargeGlide. When I fired it up after the install I get a recurring DTC "P1655".
I haven't been able to define the code as it's not listed in my service or electrical manuals, but I suspect it might be related to 'no/low compression'.
I guess my question is in 2 parts:
Can anyone define DTC "P1655"; and
has anyone that has installed S&S EZ start cams seen this trouble code come up after the install.
The bike runs fine, (in fact really good!) I just don't want the code to come up on each start.
One thing to consider is that I did the cam install in conjunction with the Revolution Performance EMS system. I suppose it is possible that the code is throwing in conjunction with the EMS install but I can't confirm that.
Any ideas on this one much appreciated!

If it runs well, a piece of duct tape over the code light should work.
Don't mind me;I'm just a wise ***. Actually not sure what the problem is;prolly should bring it in & have the code read--not sure that cam install can throw a code. Prolly the tuner.

To the problem-- my thinking is that if the EMS can't "see" compression in the first revolution or two it might throw it's hands in the air along with the code... I dunno-- that's why I'm here..
Thanks again for the laugh!

Not at all but my EMS was sent to RevPerf for a reflash when I installed their tuner at the same time as the EZ start cams (these have a decompression release trigger till the engine is turning 700-800rpms).....

If you want my opinion I expect that when your ECM was flashed it was flashed with a 2010 program which is looking for the ACRs that came on some of the 2010 motors.
The 1655 code was not in my 09 electrical service manual, but it was in the 2010.
So to stop the code you need to use the SEPST or send the ECM back and have it re flashed. You need to go into the setup section and tell the ECM that the motor doesnt have ACRs and then it will stop looking for the ACRs and throwing the code when it cant find them.

I just read the blurb about the EMS on the revolution website.
The EMS must talk to the ECM over the CAN bus, and the EMS must be programmed to tell the ECM that the motor has ACRs.
The revolution guys f*&ked up and programmed the EMS wrong. It will need to be reflashed.

If I were to take the bike to a dealer here in Oz I take it they could turn off the ACR's? I know it would be at a price but....

I dont think so, the EMS must be constantly talking to the ECM and reprogramming it to tune it.
The EMS will have the parameters of the bike in it, no one local will be able to change them. Bugger.
