Give donna a call
I'll call first thing Monday when they open. Thank you
Might be around tomorrow
You could send them a text also, and they will get back with ya
Yep that's your ehc for you. No here is the kicker half of the time it's in the ehc and half the time it's in the wiring harness. With axles you only get the ehc. With DOCs you get a ehc and a wire harness made specifically for your bike , year model and plugin play to fit into whatever ehc system your bike currently has. It usually take a couple of weeks to hand make your specific harness. You also get a new ceramic headlight plug and harness. And an battery system charging option, which I highly recommend. I got that and it told me my VR was starting to go out way before it did and fried anything. So you can get a good half system that is quick to put in or you can get a great full system and not have to worry about the ehc and any part of the harness in the future. Ppl report harness problems seams like as much as actual ehc problems. So do it all and not have to worry about any part of it or do half of it and hope the other half holds up. Me personally only want to have to fuck with it once and done.

That's true but I'm sure there are more dogs out there running the original ehc than not either route is good Axel made many improvements to the ehc and eliminated a lot if not all the weak points
So what happens if you spend 600.00 replacing the EHC and it has nothing to do with the problem??? to me its not ehc related due to your symptoms. I don't know allot about the fuel injected systems but IMHO your issue does not point to the EHC.. Why not send it out to get tested first. Recommend curtis at wild steed work..
from their you can rule that out and may save yourself 600.00 plus any additional cost to fix another problem.. that is where I would start.
Very true. If your going that direction have harness checked second.

one of The reasons I don't think its a EHC issue is due to the fact when you crack the throttle it and it keeps running to me that seem like a fuel injection/fuel issue.
Sounds similar to the situation that usnchief and Viking went thru maybe one of them can tell what they did to solve the problem with the efi
Could it be a bad map in the vfi? When I first got mine it would run fine then out of the blue not want to start unless I kept on the throttle or it would not hold sitting idle. Then it would go away and then come back. Fixed it when I put an unlocked vfi and a good map now runs like a charm. I'm just throwing it out there you guys know way more than i do about our beloved DOGS.

You could send the EHC to Slick117, he can check it out also for free, just pay the shipping to and from
With all kidding aside it seems easier to text and when she returns the text if you really need to speak with her that is the time to call she will answer
Well I guess we agree on texting
I'm the one who started texting them I hope her phone isn't getting blown up from all you wankers
Ker always gotta be a smartass or just loves being
Let me add a couple more points of information.
1. My mechanic hooked up to the EFI controller and could not find any stored faults. DOC told me that what I was experiencing was "limp home" mode when the engine light would flicker. Once my mechanic had the bike for 4 weeks he could not duplicate my problem. He cleaned and replace the small wire ground - he felt it was suspect. I rode it for the entire summer with no issue. Yet it returned that fall (2015).
2. I've replaced the fuel pump, but for another issue.
3. The singular issue is no power to the fuel injectors intermittently while riding. If the bike dies then when I hit run the fuel pump will not energize until the bike sits for awhile. Maybe cooling down is the issue, but I've been successful starting the bike after only a minute or two as well.
4. Every component in the fuel pump circuitry has been replaced and the issue has occurred with both old and new components - except item 5 below.
5. The only components that remain are: the EHC, the S&S EFI controller, the wire harness and the hand control switch.
6. I don't really suspect the hand control since it only provides the initial on signal and that signal is then held on by the EHC. I seem to drop power when I'm riding - momentarily and it sends the bike into limp mode for about 1 second or less.
7. That leaves the EHC, the S&S EFI controller and the wire harness. I'm certainly concerned that it may be the S&S EFI controller. However I can't say I've ever seen a post where someone had to replace it.
I'm basically resigned to giving into the "EHC is junk" mindset and going for the DOC ESC replacement. I haven't been able to ride the bike since October 2015. I've been distracted by a job change, a move, new house and finally (thanks to the wife) a new beautiful Road Glide last spring. So I'm riding, but missing the dog badly.
Looks like I'll buy the DOC ESC later this month
Get in touch with usnchief he had similar issue and I believe it turned out to be the end, send him a pm
Your choice in the matter and probably not a bad move.
Its sounds like you have been pretty thorough with the troubleshooting, I still think I would send it out to get it tested to Eliminate or identify what the problem is.
Just my 2 cents
I'd say wiring harness but it sounds like you don't touch anything and it fires up after just staring at it for a bit?
I also am a prominent supporterer of just replacing the EHC for good measure when folks can. Some have had luck with them most have not and it's a very simple 6pack project. And I don't know about you but as far as luck goes I need all the help I can get!
