Medium level Autel scanner can do it. Example MS906BT.
No need the Pro one which has that expensive J Box , J2534 but can do higher level programming.
I do not know what is the ACTUAL meaning of 072, why also there is ECO start stop there ... LOL.
076 is what I choose to kill ECO.
THE CHARGING TEST...........
EASIER VIEW
At least, the Autel MS906BT felt cheaper by +-US$150 now...coz it has done that much $ worth removing ECO STAR-STOP, compared to buying the removal service.
That looks like a good step in the right direction with Autel helping code out options.
The average voltage does not come down so much below 12.6v. This shows that ECO was influencing the voltage regulation.
noisy ECU power
There is something uneasy about this much noise overlapping DC supply.... your new DVM-DSO is going to come in handy to identify noise sources.
Pri, so does the ECO button in the center stack no longer light up, too (indicating it's off)?
I will be watching this with interest. I will wait until someone does this with an iCarsoft scanner.
Meantime, I need to run to the grocery store to buy some popcorn.
The ECO button still there , and still has GREEN led activated at engine start, but it is of no use now. I can turn the green LED off by pressing the button, like the old usual method.
So I guess since the ECO button is on a different module called N72/1 - UPPER CONTROL PANEL MODULE , I need to access that module ( assuming I can ) and kill that green LED.
You still have 14.8V charging, what is shortening battery life.
This is part of "smart charging" so I wonder if you could disable that as well?
I doubt 14.8V can be removed, it is part of the alternator's built in voltage regulator.
Seeing the graph alone is not so "clear". One need to see the Instrument Cluster VOLT + AMPERAGE in a video to see what's going on, since I can't log the net AMPERAGE into the battery ( B95 Battery Sensor ) using excel.
I am preparing the video.....

I think I know why engine computer voltage reading can be seen so jagged if LIN cable disconnected.
The engine computer does the firing of the coils, so it operates within its circuits...albeit ground side switching... Up to 50 load pulses per second per cylinder approx.
When alternator LIN disconnected, the voltage being maintained so flat, it is easy to see the jagged voltage reading at engine computer as a result of that much load change.
I think 1 coil needs like 8 amps. So 50 x 6 cylinders = 300 load pulses a second.
If only I can graph the gross amperage out of alternator and the NET amperage into battery, that will be another very jagged graphs for sure.
Those graphs represent typical 24-27 minutes of engine run.

This high power noise shows impedance problem, either on the fuse feed side or the GND return.
A running alternator can feed the COP'S demand anytime.
I am not saying this noise is a show-stopper that will trigger limp-mode... but imagine the ECU measuring this voltage to regulate the alternator with these jagged edges, not pretty.
Ironing noise is good :
Isn't this ECU Power noise caused by undersized power wires -or funky ECU GND??
😏
Yes agree. Ironic isn't it. N3/10 engine computer controls the alternator charging profile, and yet the N3/10 itself is "voltage-stoned".
Its like a driving instructor high on weed teaching a student how to drive straight.
N3/10 engine computer until now we do not know which circuit or region of it, is reporting the so called "ECU voltage".
High suspect is fuse 27 as the region/circuit which where ECU Voltage report comes from, but who knows.
Fuse 22, 23,24 and 25 are also feeding the N3/10. <<< All these fuses are Negative switched
Its much more complex than what I can imagine how it would work, I guess.
The charging profile now with ECO START STOP completely disabled by coding, is still not a dummy one like when the LIN cable is disconnected from alternator.
The car still does the DISCHARGE thingy, but not as brutal as when ECO START STOP still reigns supreme.
The good thing is, my dynamic idle is not lost with ECO START STOP disabled by coding.
I shall play with the Autel MS906BT more and see if I can do extra on this ECO thingy.
I just seen this post using the higher end Autel : https://mbworld.org/forums/w213-amg/...ml#post8235813
OP's Autel menu called the process RETROFIT, sounds so more less offensive than CODING ha ha ha.
I do not have RETROFIT menu.

This video is as good as I can get a 101 on Autel for W212, his Autel used is like mine, middle level one.

I used my autel to disable ECO as you demonstrated, thank you. I tried changing the engine codings to remove the torque limiter and change the pedal mapping, but it refused to accept those for some reason. I dug around looking for full ILS but could not find it. Any other goodies you've found?
I have seen the Torque thingy and the throttle pedal mapping, but I have not try them , as I do not know their actual "values".
I think Autel like mine is still only a "1/2 baked cake" , many coding information/designation on the W212 in my MS906BT is only written as CODE and their B????? VALUES which we can not refer to any user manual.
I have not found any more goodies
Example : 68 to 71 and the 73, what do the CODE designation mean ? . Why would Autel include designation they can't even explain ??
The torque thingy #56, I think I know what they mean. It is not about "locked" power potential like some fancy cars can do. It is about driveability. See attached PDF Torque coordination, FUNCTION
I only have this MS906BT for like 2 days, so I am quite a dummy on it ... LOL.
I think there is a forum of Autel user which can be accessed thru the Autel tablet, maybe that can help.
I will try to call Autel Indonesia distributor and do some digging, see what they know about W212 "unexplained codes".
I bought this Autel is more for diagnostic and not coding actually.
I am thinking to get a Xentry clone.
Charging Profile Update - ECO CODED OFF, Daytime vs Nightime
Hhmmm, I never realized the charging algo is as such .... .
See latest 2 drives result.
Attached something I just found on WIS. ALTERNATOR INTERFACE FUNCTION.pdf
Damn it WIS !!, their search engine is so weird. Its never predictable on what "small" documents will pop out.
For alternator reference voltage, it is stated engine computer uses circuit 30. So that is at Front SAM , and being the most upstream of circuit 30.
I think the so called ECU ( engine computer ) voltage being lower, I do not need to worry as far as battery charging is concerned, but I am not happy still...if something so important doing firing of spark plugs
and combustion management does not get robust stable voltage.
Part 2 investigation for N3/10 engine computer voltage stability improvement shall begin .....

I actually do have a xentry clone with vediamo and intend to pursue it with the those instructions, I was just hoping Autel had an easy cheat mode way to do it ;-)
I am not too good with electronics, but I think the regenerative braking takes much more than simple alternator module to operate.
My Sprinter with 4-cylinder diesel did have "smart charging" as well, but with no ECO stops and no regenerative braking.
The program would give it >14V charging after morning start, but then would keep it at about 13.5V for rest of the day. That is the best for long battery life from what manufacturers say, but then you don't regenerate the energy.

Sweet . I hope you can teach me Xentry next time.
Have you tried changing the model market to REST OF THE WORLD and not USA ?
Maybe it can unlock more European version Coding ?
I have this page : Your Autel has it too ?

Starting with facelift I think, this ECO B03 option is MB way of playing "green"....
I can't manipulate such algorithm. Got to live with it.
Can you code the annoying throttle delay with this thing?
There is a different pedal map, but I know nothing of its actual "mapping" and I believe it has no effect in any sporty sense as tried by DubVBenz.
MB in non AMG car, I think will focus on comfort and smooth power delivery.
I read Sport+ transmission mode in AMG C43 many find as "not comfortable" at slow speed ... well expected I would say if slow speed is the use, or in traffic.
NON AMG
MB throttle pedal even in sport mode ( regular sport ) is indeed "old-man" comfort oriented , untill u kick down and click that last pedal travel. Overall it is too comfort oriented.
I dont like it too, but I have MANUAL mode , but I almost never use it though. E400 has decent power for a 3.0L and a good low torque, so can't complaint much.

I do have the separate menus for the left and right headlights, but didn't see anything obvious in there. If there was a translation of the codes that don't have descriptions somewhere, I'd be there are some goodies in there.
