- apriliaeldor coil installing packs
Hi, I'm new to this forum, I recently got my second blown ECU in just 2 weeks of riding after getting it back from a 2month waiting list to get my first new ECU.
Ducati doesn't want to help me with the coil problem so I bout ELDOR on ebay.
I was wondering, has anyone tryied to diagnose the coil packs prior to installing them ?
Just want to make sure they work before swapping them.
Thanks

This is exactly the problem I got, went to Ducati and they told me the ECU is blown... Sorry for the bad news if you haven't figured it out yet.
Replying to my own post just to let people know that I picked up a set of eldor coils from an 848 ducati, same plugs as original hyper ones, fitted and working no problems.

Hello there. I am new here. My name is Eric, I am from Brazil and I came here by @hyperbruno, who lives near from me.
I just got a HS 2015 in April. It had 27.000km and around the 29.000km the ECU dies. Again! I know this was the second time 'cause it had glue on it. Anyway, I had to buy another one, used, from Ducati's mechanic, it costs 1.000 dollars.
The bike already have the filter on dashboard, it was installed in 2019 I gess(don't remember for sure).
Hyperbruno told me about the forum and sent me the link to this topic. I already have the coils and will change it tomorow.
I want to thank so much @dragoontwo for the tip.
(a picture just to say hello)
This was on my very first ride, taking the bike on another city, 1.200km away.

Got the job done!!
I have just finnish the job.
No problems in the process. The tank is full, but I can lift well.
Used the originals plugs(did not found the plugs here, just on ebay and it would take much time and I have already the coil packs, so...)
Cuted off the plug on Eldor coils and remake the plugs welding the wires. It is like original.
The reassembly was right too.
The wire for horizontal cillinder coil was short, used the 857084 p/n but no problem, just let it there, I did not attached to the frame.
The horizontal was short too(857501) but it is attached, with zip tie.
Now I will not worry anymore about the ECU!
PLUS: my bike makes a weird sound. It sounds like a young cow, you know. It is the gas vapor leaking from the tank. It haven't canister anymore, just a tube from the valve to down, that leaves the vapor go out.
it is funny!! Suddenly it makes sounds and we guess if was the bike or we are in the farm. Hahaha

Glad you got the coil job done; one less thing to worry about! I've heard about the cow sound on these bikes before, but my bike seems to be more polite so far.

Sorry to hear your ECU trouble.
On your 4th picture that shows the 2 coils together.
Maybe it is a trick of the photograph, but the 2 coils look very different lengths.
Is that so?
I read the Eldor coil is a tighter fit.

Hey. Yeah!! They are different. Eldor coils are bigger. But it is not an issue because the rubber is soft and when you plug it in place the screw holds it. And the insulation on the top gets more pressure.
Hi all,
New to the forum but have read this thread and need to swap coils after my findings. Have had a new dash and ecu installed by dealer at my expense, and want to keep riding this hyper; it’s a blast. Looking for clarification, the Eldor coils are plug and play, and the Aprilia coils require some cutting and soldering to be compatible?
Thanks in advance!

To clarify, Eldor are the makers of the better coils fitted to both Aprilias and the later Ducatis. If you go the route as described elsewhere, you may score some s/h Ducati coils that will be plug and play, but the Aprilia ones don't require very much modification to fit the HS or HM and may be easier to find.

Yeah, this model is plug and play... but here I could not find this one. So, I made the modification on the plug.
Just watched a video from some guy who make the modification and tag the forum on youtube, it is "Rudeboymoto". He tags this topic in particular, maybe he is here.
Hi Jeff, wellcome.
The models 857084 and 857501 have the plug diferent and need to be changed.
But the model 38010144B is exactly the same, just plug and play.
Take a look in this tutorial video

I just watched your video couple minutes ago...
And subscribe and put some more videos on the list to watch later.
You and I had the same dream: Hypers!!!

I also had a drz400e that I converted to supermoto. Bored n stroked to 470 with wide ratio trans, pumper carb and big cams. Was a fantastic bike that hurt a lot of feelings.

Hi,
I have done the swap before the winter.
Now the bike won’t start anymore m. Has anyone had the same problem ?
It turns over but it’s slow( battery fully charged )
It seems like it doesn’t spark.
I’m going to change the spark plugs next to try but I was trying to see if anyone had the same issu.
Thanks

Given your battery is actually healthy and can deliver the amps rather than just registering 12v, it could be you have the next Hyper problem; the useless starter motor. The original starter motor can go bad, use up massive current and still not spin the engine fast enough. The answer is a newer Denso motor, preferably a used one from a later Ducati. This issue has been dealt with extensively here, so you should be able to search for it. Removing and fitting a starter motor is a significant job as you need to get inside the engine case to get at the bolts. Good luck!
Hi thanks for the answer.
The starter was changed by ducati dealer two seasons ago. Also, I have a 2015 so technically the starter isn’t suppose to be an issue.
Might be worth trying to see what brand your starter is, as we've heard of Ducati dealers simply replacing a duff one with exactly the same.
