what is a sert??

 

Screaming Eagle race tuner, it is harleys fuel injection tuner. It can read codes, data log, change rev limiter. It is no longer made and replaced by something else. One reason it was repalce is probably something more modern. But also about 7 years US EPA came down on harley. I am not positive but I believe they created a new tunere to make them happy, and again more modern probably.

It used to be harley could change the map in your ECM. The other tuners would have to add second device, piggy backing and dumbing the signal. Now after market can rewrite the ECM. I am guessing they cracked it, I doubt harley turned this over. I think some of the people working on this went off on their own. I could be wrong, it was years ago.

I have 2007, but have not used my tuner in 15 years. So I am rusty.

 

Think we have determined it doesn't. However, owners manual will tell you.

If you don't have one, go to harley.com and they have it on line free.

Think you need your vin number.

My summary is it's probably a coil.

Please when you get it fixed, let us know. Your title is clear so others searching can find it.

ROUNDER.. GOOGLE HARLEY EITMS. It doesn't use fuel to cool. It just pumps AIR.

 

Here is the manual for his year. Dealer or sert needed turn parade mode off. Adds fuel, but keeps spark to cool down, then takes away fuel. page 13-14


Myself I would replace the coil. Only interesting thing is, why does it appear to make a difference cycling power.


Phase II it richens the AFR. An increased amount of fuel in the air/fuel mixture has a
cooling effect on the engine.

Phase III: If the ECM detects an engine temperature that’s still drifting higher while moving
or stationary it directs the fuel injectors to skip, (only when the bike is stationary) and not
deliver fuel on every intake stroke. This limits the number of combustion events taking place,
which produces less heat.


Model Year 2007:
New for all Big Twin vehicles there is an optional Heat Management System called the
‘Engine Idle Temperature Management System’ or EITMS. The Tuner software allows the
EITMS to be turned ON/OFF.
For those riders who frequently find themselves in riding conditions where the vehicle is
subjected to prolonged idle conditions the optional ‘Engine Idle Temperature Management
System’ (EITMS) is available. This feature offers limited rear cylinder cooling with the vehicle
stopped while the engine is left at idle.
Enabling EITMS will cause the rear cylinder to be shut OFF when ALL of the following occur:
1. Engine Temperature reaches ~300F.
2. And the vehicle is at IDLE.
3. And the vehicle is STOPPED

 

Roger that.. but it doesn't allow for fueling but no spark..

Also, that is not about the EITMS system introduced in 2008, that shuts off the rear cylinder at idle.... two different methods of temperature management

 

Very interesting, but not to the OP's question.

 

Remember Jake, do just guess. The coil is easily checked with an ohm meter. Anyone with a home,car or bike needs a AC/DC/ohm meter.

Let us know if you need the resistance it should be.

Post 8 is probably what it should be.https://www.hdforums.com/forum/dyna-...l-testing.html

 

From the 2007 Dyna Service Manual:
Ignition coil primary resistance 0.5-0.7 ohms (A-C, A-D)
Ignition coil secondary resistance 5500-7500 ohms (A-HT)

Check the plug first. If there' no fuel, then it's probably not the ignition coil.

 

I've had bad coils ohm good. Keep in mind it does not do it all the time.

 

I have never had a problem like the first poster. Will the firing cylinder be dry also? If by chance it's dry and I would think unless you caught it just before it fired to actually see wet, would that be a bad ECM?

Looking at A,(B ion),C,D What is the A-HT? A to the sparkplug terminal?

I only have close to an 07 is the electrical diagnostic 04 Softail and 08 Dyna but they are the same.
