EHC replacement

[Axel]

Hi Sutton,

Sorry, there is no possibility for an update, cause the box is complete potted and there is no port outside available. The older EHC versions work w/o problems and it´s just a small software update in my opinion. I hope it would be ok. However, just feel free to send me a mail if you feel unhappy with the old box and we´ll find a way.

All the best!
Axel

ok thanks Axel. Still not sure exactly what changed @KaptinAmerika could you chime in here and let us know what the change is?

Also @Axel is there any way to add the factory air ride programming into your unit? I have a spare Axel unit sitting on the shelf I'd love to swap out but I'd then need to hard wire a switch and I can't find a clean way to do it.

Hi Sutton,

Hm, for driving the air ride I need to implement 2 electronic switches in the EHC, what is a bit tricky due to the small space inside and the small microcontroller, what have no more pin available. What do you think about a one button control, what control both directions? One press on the button will activate the pump as long as you press the button and one more press on the button will activate the release valve? I can change the software of my Multi Flasher relay (http://www.elektronikbox.de/mini_last_uk.html) in the required way. You can use one of the 2 bigger buttons in your handle bar (Head light switch or Engine switch) if you cut and separate one of the button cables and connect it to the updated Mini Flasher relay. In my EHC I have wire together the 2 button functions of the big buttons. That´s why you could have 2 spare buttons if you cut one cable per handle bar side. I hope you can follow my chaotic describtion ;-)

All the best!

Hi Sutton,

... do you want me to draw it in the schematic of your bike? It´s much easier to understand if you look to a drawing.

All the best!

Sutton the software update he made just requires you to hit the Run button to activate the ignition like the OEM setup prior to hitting the start button

The older software activated the ignition with the key turned on so you could just run key and push start.

Well technically the new updates gives you the option to toggle a preference between the two options.

1) Turn Key
2) Hit Start

Update
1) Turn Key
2) Hit Run Button
3) Hit Start

Is there a way to keep the ignition off when the key is turned on for the older Axel units? I assumed the OFF/RUN button did that(OFF). I always turn key on, hit RUN, then hit START to start my bike. I assumed the ignition was OFF till I hit the RUN button.
Eric, Can't both your options listed for the NEW EHC be done with step 7 on old Axel module?

Hi Eric,

Thanks for the good describtion. I wish, my english knowledge would be better ;-)

All the best!

If you did that, could you update this EHC or would I need a new one? I'm not sure how many of us have the factory air ride, but that's the only thing holding me back on the install. Curtis said he could help me with a simple switch, now the problem is just finding where to mount it. I could drill a 3/4" hole in the left side cover and mount it there I suppose.

On the factory EHC you hit start and then the high/low button airs it up and down. Then start again to exit the option or just wait 10 seconds and it goes back to the high/low operating the headlight.

Your English I can understand however I doubt you would understand my German, matter of fact neither would I! Haha

Hi Sutton,

My EHC can not converted to Air ride, but you can use an updated version of my Mini Switch Relay, what you can put under the seat and connect it to one unused button. I´ll contact Curtis and ask if it makes sense fix a few of Mini Switch Relay and put it together with the next order.

Do you know the power consumption of the pump ?

Eric, I found out that understanding other languages is much easier after a few beers...;-)

All the best!

Axle did we cover this in here somewhere? What is the amperage on draw on the starter? Did you keep the 100amp switch it knock it down to 40? I'm just looking at some random after market Harley starter relays and all seem to be at 30amps, but not sure that covers these big Inch motors.

I'm just looking at that new Munit blue, looks pretty slick!

Hi Eric,

Thanks for the question. The internal high side switches, what i use in the in the EHC can handle up to 30 Ampere before they switch off. I test every EHC with more than 20 Ampere for 20 seconds with a 7 Ampere polyfuse. The starter solenoid need 18 Ampere. II have checked the current to the starter solenoid in my Ridgeback and in a few K9 and there is no need in my opinion to push the starter button longer than 20 seconds. I had tested several fuses last year until I decided for a 7 Ampere Polyfuse, what is fine in the potting compound, that works at heatsink material. I think, it is the balance between a good protection and a start without problems. However, the starter need more than 100 Ampere, but it is wired direct to the battery and not to the EHC. I hope you can follow my confused describtion ;-)

Hi Sutton,

Sorry for the late reply. I have finished an Air ride control with a memory function, what uses one half of the 2 big buttons at the left and right side of the BD handle bar. Curtis just got a device for testing an I wait for the test result. The installation is not complicated. You just need to cut 2 cables from the handle bar button units and connect it to the Air Ride Control and power it with 12 volt from the battery. You are be able with my system to change the Airride function at any time when you ride, unlike to the old EHC, what need to be setup before riding. Just feel free to contact Curtis for an update. I attach the manual.

All the best!

Thanks Axle, makes sense. Yes I was really asking about the solenoid, which you answered at 18amps!

BTW air ride adjustment sounds cool! Thanks again for the work you put around this.

Yes Thanks again Axel
Your Ehc has worked flawlessly on my bike.

Thanks Axel, I'll wait and see what @KaptinAmerika think of the unit. Also, with the factory air ride you can change it at anytime. Bike running or not you press the start button and then use the high/low beam switch to air it up or down. Mine leaks slightly so I have to add air from time to time on long rides and I can do it while riding.

 

[PROFLYER]

You are saying with the air ride system you can push the start button with the motor running and use the high/low button to adjust the pressure. It sounds good. This is with the original ehc?

Yes. If I hit start (before run) when the bike isn't running I can operate the air ride before I even start the bike. I like to air it up before I get on so it's easier on the pump. Then I hit run/start to start it like normal. While riding I hit start and then H/L to change the air pressure. I don't have a pressure gauge, but you can tell how firm it is. Or I can let all the air out and ride it around on the bump stops that were installed as part of the kit like a ridgeback. Fender really hugs tight on the tire too when the air is out which looks cool. It raises up/down 4".

Hi Sutton

Sorry for the late reply. I was a bit in Holyday and had not looked in this forum for 3 weeks.

Yes, I haven´t think what is happen if the air ride system leak a bit. In this case is my Air Ride control a bit useless, cause you´ll need to press the button to release the air before you can press the button and pump again to the required height.

How long is the average time to pump up the system to the maximum height, when it was complete empty and how long are the deco valves usually open until the system is empty again? I know it might vary from system to system. It´s just to get an idea.

All the best!

Ok, I'll try that. I always air mine up to around 80 psi before I take off. I had all the leaks stopped at one time but now have another slow leak.

No problem! And yes they do leak a bit. The fittings aren't the best. It holds air for a ride, but not for weeks on end. The factory EHC has the ability to change the air pressure at any time, so you can add air or let air out anytime the bike is on--running or not. If you're not able to program that same functionality, then a switch of some sort would be the better option.

As far as how long, I'm not sure. It airs up from empty to a riding pressure in about 20-30 seconds. It lets the air out quickly, but that's simply because you just open the valve and the air rushes out. I can air it down from full in 2-3 seconds probably? A timer setting wouldn't be a solution though. It needs to be adjustable up/down at any time just like the factory EHC does.

Hi Sutton,

Thanks for the useful info. I have implement a normal toggle function in the "toy" as well, what allow to use it as normal "One button up/down relay". However, I don´t have the right idea right now how to make it a bit more comfortable with one or 2 buttons.

I think, your suggestion, one button for "up" and one for "down" is the best and easiest solution. I´ll change it in the way what you suggested.

It´s somehow a bit pitty for me, cause the implemented microcontroller could do more and as developer it´s hard to resist to program something (...in this case an absolute useless function)in the device ;-)

All the best!
