Dang! Sorry to hear that MRD. You've had a tough road with this one.Well, had a bad day yesterday. The SS has not run right since I installed the DDM Supercharger, it would run rough at idle and seemed to be missing as I drove. Yesterday I took a friend for a drive be it started running so rough I had to turn around and go home again. I have been problem shooting on the phone with Jeff but I am down for now. In a few weeks we have the Oyster Run so I really need to get it back on the road by then.
Pulled the plugs, they look good, checked the map sensor and all the connections but everything looks good on the outside. It sounds like I will be sending parts back to them for testing.
Looking forward to hearing the results. I dig this kind of troubleshooting process. I know it's early. Dumb questions: @MRD What parts were sent back? Just the SC kit or some of your SS parts as well? @[email protected] Are you just trying to rule out the possibility of a manufacturing defect in the SC or is there something else that can be discovered? Seems like trying it on another machine limits the diagnostic abilities.Parts arrived and are installed on our shop sling for testing.
Very true. Fortunately it's not mine. But if you do have issues, it's great to have the kind of aftermarket support that we do here. Way better than the dealer.You may dig it but you sure aren't enjoying your slingshot while it's in the shop
Hopefully all is well after the new parts and reassembly. Either that or buy Jeff a plane ticket.The only vacuum plugs/lines that I am aware of is the one coming from below the throttle body which feeds the BOV and the one that goes up to the unit right behind the engine near the firewall. The second one has a black cap that is in place and secure.
I have inspected every inch of the one that goes to the BOV and all is good. The other one as well, it is made of a different plastic type material and I can find no leaks. If things don't get better after the new parts go on I will try to dig deeper.
Wha? I thought this wasn't possible. Is this new? What information does it give?I ordered an OBD 2 with the adapter, made for the Polaris Slingshot, it cost around $370 bucks but it may help if the new parts don't fix the problem.
I don't believe I have heard about this in any other thread. Everyone says Digital Wrench is the only way in.....or maybe I need to lay off the rum this early on a Friday? Either way. News to me.OBD Diagnostics
Go to this site, they sell one specifically for the Slingshot
You do know there is a 3rd pedal called the clutch right? :facepalm: Just kidding. I couldn't resist.It has done this since new, no one else has this problem?
Crap. That's not good at all. Hopefully Skagit Valley Polaris will work with you after all the mods.I disconnected all of my electrical accessories and took a 40 mile run. The miss is still there so that rules that out. I am starting to connect the dots and I am pretty sure the problem I am having with the bucking I get at some brisk take offs is a bad miss so I suspect the two are one in the same. The bucking has started to come on anytime I throttle hard in the lower gears.
I am lost as what to do from this point other than to take the shot gun approach and start replacing every sensor that has not already been replaced.The voltage drop that is seen in my data from the scan tool still happens when the fan comes on even without any accessories but I am not sure what to think of that, I believe it would be normal for a high draw motor like the fan.
The only remaining components will be the cam sensor, the cam actuators and the throttle position sensor, If these are not the problem then it has to be the computer. This problem has been there since I bought the bike new on 2016.5 but it never affected the idle until I installed the Supercharger and had the tuning changed.
Did the bucking stop?So far so good, it seems like got rid of the gremlins. I still get a very loud back fire now and then but I have checked for leaks all the way to the first muffler. I have a new setup coming so I will be very careful to ensure no leaks when it comes.
