Thunderheart Ignition Module??

[xxcarpxx]

When I bought my 07 Chopper, I was told the EHC Module had been replaced with an upgrade... as I have become more knowledgeable about BDM (thanks to you guys and the forums) I realize I still have a factory EHC.. Now I'm beginning to wonder if the previous owner was confused with a Ignition Module upgrade.... I have looked into the Thunderheart Ignition Module since I have had EHC issues.... It looks as if I may already have the Thunderheart Ignition Module.... is there a way to visually determine the difference between the Factory and upgraded Ignition??
Below is a picture of what is currently on my Dog...

I'm pretty sure that is the stock unit. I don't see the mechanism that allows you to adjust the timing.

Thanks for the info.. I was hoping I may have lucked up with a Thunderheart...

Can you give us a better picture that isn't blurred?
It looks stock but can't tell what is in the white area next to the LED.
Some of the older TH programmable modules had a white dial.

Yup, what Kap says.....

Look for a dial with an arrow and numbers... if you have it, then you have the ASM5012 programmable IM.

@KaptinAmerika .. I don't keep the Dog at my house due to the fact of not having a garage to store it in. I'll have to go over this afternoon and give it a look.... If its simple as a dial, like @francoblay1 says, I'll be able to give it a look without having to post a better pic..

Thanks for all the info you guys have offered...

 

[francoblay1]

It should have a dial like the one in this picture, it could be white too.

BTW, If you need the Manual for it I have it in PDF. Or just go to TH webpage, you will also find it there.

I got around to working on The Dog today... I guess I do have the Adjustable Thunderheart Module....

 

[francoblay1]

Yes you do! and you are running way to high if you ask me!!!!!!!!

F= 6240 Rev Limit RPM & almost 40* advance!

Most people here runs at Setting #3 or 4.

See page 5 in the Manual.
Fuck, too large... pass me your email address if you want me to send it to you.

Extract I kept from an old post in here:


"Ok, i am a research nut! I called S&S, and Bob Wood, and come up with the same answer on timing. They both say that 30-32 degrees of advance is what makes these motors run the best. So on the Thunder Heart, setting the box at the 3 or 4 setting should give you the best overall performance. You can go to 5 if you have good gas and live in a low altitude location.


Setting 3 is 30 degrees


Setting 4 is 32 degrees
Setting 5 is 34 degrees
Setting 6 is 36 degreesI was told by the local BDM dealer that with stock compression to be no more that about 30 degrees. I ran mine at 30 and 32 and I am staying at 32 for now until the gas goes to shit!




All I know is that bikes do get hot, traffic or no traffic and more than 30 degree timing on a hot day will eat your lunch sooner or later. You like what you have and I like what I have so it lets ride."

Manual is on its way.

I am not good at electronics so.... I just went by what everyone else was saying. But definitely you are running it on the highest setting possible!

Just got the email... Thanks @francoblay1 .... I may need a little tutoring when it comes to adjusting and setting the time...

Am I reading it wrong? I don't one so not 100% sure, but is it not set to 3 and B? Sure looks that way

I'm not sure myself... being the reason I lean on advice from all you vets..... it can be deceiving...the "slots" line up with "3 & B"... but at closer look, there is an arrow on the dial pointing to F....
But as I mentioned earlier, the Dog run great until the EHC fried...

 

[francoblay1]

I see the arrow pointing at the F .... but hey.... I might be wrong....

I see the arrow pointing at the F .... but hey.... I might be wrong.... just checked again, the arrow definitely is pointing down to "F"

Click on the image to make it bigger.... you will be able to see the fat arrow.... also you will see marks from the screw driver.... they have been playing with it several times for sure!!!

Didn't realize there was an arrow figured the thing was just using the slots. I zoomed in I see it now. Don't know why they just didn't use the flat head slots ..but oh well

 

[francoblay1]

either way 3 & B are not the same..... Letters have higher Rev Limiter than numbers.
