There are a lot of things that could cause your regen to appear to be lost.
The Bikes main concern is keeping you safe and the wheels pointing down.

What was the temperature out?  What was the road condition, and weather conditions out.

How aggressive?  If you are doing 100 plus MPH sometimes regen will seem sluggish because of the sheer energy you are trying to put back in and if you are on a rough road, not necessarily banging your ass all over the place but a rougher surface and the tire starts studdering and skipping across it, the ABS will take your regen out to try to keep the wheel from what it sees as locking up.

I have had on cold days, my regen go to hell, and wondered WTF, and upon research figured because it was so cold out, the tires were cold too and skidding a bit along the shitty roads we have here.  They are old and the surface is very rough, not a lot of traction and all it takes is a little slip and it'll kick right in.  Warm tires that are squishy can grip that road, tires that are at 38 degrees, not so much.

when you finally slow down enough that there is not such a demand on your hard slippery tire, it grips and then the regen will kick back in because it feels the grip.

Ive  experimented with the regen a lot, wondering why sometimes when I hit it full it's really wanting to push me thru the windshield and other times it feels like it's barely on medium setting.  After a few weeks and a lot of notes,  yes, road surface plays a lot, and I came to the conclusion it's all about traction.

Cold and or crappy roads make a huge difference.

I am back with more news.

red light only at top of dash (no regen) are completly random - I made trip week ago (1200km 2 days - regen off situation happened maybe twice) - I have break for few days and for example yesterday I got regen off while I am start riding (had to stop and turn off/turn on), after 10km I stopped for shopping, back in 10minutes and same situation - regen off - wtf

as I said SoC doesnt matter bcoz it was 60-70%, also there was no tire spinning or something like that

today 200km ride - will see

The red lights at top of dash could also be your traction control kicking in.  If you hit a bump, it doesn't even have to be a big one, or a washboard type of road and it's lumpy, they'll turn on momentarily as you bump along, especially if it's colder out and the tires are more prone to jump / bounce off road instead of flex and absorb it. 

You could also have a buggy update install as well, which would really suck.  What mode / number is your traction control and ABS in just out of curiosity.

red light only at top of dash (no regen) are completely random -

Please refer to the "dashboard" section of your owner's manual. Those red lights indicate one of the safety systems is being activated: ABS, eABS or TC

^{From the manual}
The intervention of the eABS
system is indicated by the activation of the red LED
indicators to the right and left of the motor power indicator.
This indicator is also activated by the Traction Control system in
case of loss of grip under acceleration, and by the ABS system in
case of loss of grip under braking.

v.43 is compatible with all bikes. I don't know why A&S is confused.

Wrong!!!


I took both my bikes in for the FW update. My Experia and my 2020 SS9-


Experia now has the V.43.


Here is what I have in writing from A&S (long story, but they had a cable to do the FW updates after all):


2020 Energica Esse Esse 9- (smaller battery only in year 2020 models):


"Firmware Update V.43:


Description: Customer would like us to attempt to update the firmware to Version 43.


"Resolution: Attempted software update previous SW version was .34, upgrade available was up to .42.


"Performed software update to 42 and checked to see if 43 would become available.  .43 is NOT applicable for this year. Confirmed via searching available technical bulletins linked to Vin." Tech 99 @ A&S @  Roseville, CA


I have no idea what the .42 does that the .34 did not, other than show the version number of "42" in the "About" screen.


I had to rush back to Reno and leave the bike there in Auburn, so I can check it better next time. But that bike did NOT have any bugs, unlike my Experia before the update,

Had my Experia updated a couple of months ago, I no longer get the "key not in range" issue and I actually get slightly better range than before the update. It has sorted a few niggles and the system seems a little less "clunky". I've not tried a DC fast charge since the update though.Smithy.

I got the "key not in range" message on my Experia on the ride home from just getting the 43 FW installed. The keyfob was in my right pocket.


Since the time of your post, have you also gotten the message?   I assume so.

Don is correct! I am wrong in this case. Firmware v.43 is not applicable to all Energica bikes. I asked around and found out that early VINs do not qualify. Like my bike. Thankfully I have a handy dandy qualification chart:

VIN numbers: ZNNP – ZNNR – ZNNT – ZNNL – ZNND – ZNNZ - ZNNF
These are the VIN prefix that can receive 043.

So check your bike if you have an older one, like me.

Thanks for the info. Didn't find that anywhere else. My SS9+RS seems to qualify (ZNNZ). Not sure if it's a good idea to update as it's running stable with version 42 and I don't want to risk that.

My 2020 Esse Esse 9, must be an early one as I purchased it in Aug of 2019, its VIN prefix is ZNNS.  Looks like perhaps the Energica VIN prefix numbers have no logical order to them by date.

I picked up my Experia yesterday and rode it back to Reno from Auburn, CA the same day.


If version 43 is supposed to fix any of my bugs, it didn't in my Experia.


In the 99-mile ride back, I still experienced several bugs I had in the past.


First bug yesterday with V 43:


I use reverse to get out of my garage. Goes a few feet and then motor dies with the same old "undefined faut-contact service".

2nd Bug:
Then I reboot, start to head to Reno. I get the "FOB out of range" message in less than a half mile.


Again around 20 miles up the freeway.


The I take a break at the Truckee, CA airport as I get a free charge.


I stop the AC charge after I gain 10% SOC (nice long break).


I use reverse again. Same problem "undefined fault". Then need to turn the bike off and on again. Next time reverse okay, no fault.

3rd bug:
Now back on the freeway. About two miles up it, my screen says that "The charging cable may now be removed".


If version 43 is supposed to fix any bugs, it didn't on my Experia.


I have not yet tried a fast charger since v 43, but perhaps that will be the only thing it does better.


But so far, I am disappointed with version 43 as it fixed none of my bugs.


Is V43 only supposed to improve charging? Has no bug fixes?

I listed bug fixes that I noticed on my experia in the first page of this thread.  I don't get an undefined fault in reverse and went with keye'd vs keyless, so I don't have those 2 bugs.

Yeah, it did make those improvements.


But those fixes are not exactly "bugs".


Now, even my 2020  SS9 shows the version number, updated to 42.


I will go to the Magic Dock and see what happens on that bike, updated to 42.  I never tried the Magic Dock on my SS9.


I will post here the results. I assume since it is not compatible with 43, it will only charge at around 8 KW.


Placerville is not far from here, where they have a Magic Dock. I will have to try it on my Experia later, as I now have it in Reno.

Don, all,

See my post here about my findings on V43...

[DonTom]

I rode my 2020 Esse Esse 9-, which is NOT compatible with 43 to the Magic Dock in Placerville today. With version 42, the latest possible FW for it, it charged at a steady 9 KW, even a bit past 80% SOC.


This is one KW better than my Experia did last eyar with version 42.


This is the very first time I put my SS9 on a Magic Dock.


And I have yet to try in on my Exeria which now has the V43.




My SS9 in Placerville today:
