That whisky is older than me! The tax stamp (1951) plus the age on the label (6 years) makes that 80 years old!

It is meant to help make things smoother, like the transmission, think of it as before ECU has to multitask (control the alternator and TCU), now just the latter (obviously the ECU does more than that but I want to say, wouldn't it be less stressful if it has less things to do?). That is the idea.
With that and the ALT-LIN, it's never been so smooth. That oil really made things nice. Highly recommend!

WIN-WIN SETUP
Yep, it's getting smoother - 400 miles in. I also just changed the oil to Motul power 8100 (https://www.amazon.com/dp/B0BVNY4LGV)
With that and the ALT-LIN, it's never been so smooth.

The engine performance simply needs the right setup to let the ECU tune up driveability.
Seat-back as the tranny learn to shift great as the throttle gradually gets predictable response.
Enjoy!

FURTHER EXPERIMENTAL SOFT-REBOOTS
Reboot is liberating power(**)... We are motivated in transforming enhanced performances to become full-time normal mode.
The original combined steps of :
ALT-LIN + REBOOT + FLOAT
May be broken down as :
(ALT-LIN + FLOAT) + scheduled REBOOTs
-- The basic REBOOT step still benefits chassis besides ALT-LIN + MOD-X.
-- That tells me the network retains an instability helped by simple power-cycle of a module that's not otherwise cycled during sleep mode.
-- I am sorting through the combinations to derive a short-list...
- CGW is responding positively to pwr-cycles, - unsure yet if this is 100% compared to whole chassis reboot.
- F-SAM likely in the same boat because it is the No1 sleepless power manager
Is also both roomate and Partner with CGW module.
What I am talking about here is further refining what network modules are causing unstable chassis to detune the TIMELY ECU/TCU PROCESSING.
> TEST PLANNING DIRECTION
-- soft-rebooting CGW + F-SAM...
-- focus on what factors/conditions are disturbing these modules.
(** : unchanged ECU/TCU limited response without prerequisites steps - Timings king is ECU)

Instead I am getting U012087 "communications with the starter or alternator has a malfunction" -- is that the code you meant earlier in the thread?

I rescanned for codes today - I didn't get a P06xxxx code for this (although I do have a P06xxxx code for the oil solenoid plug).

P06... is from oil MOD being
U012... is from ALT-LIN being
them do you have an optional "dummy-load" solenoid installed to disable CEL from showing??

TEST-DRIVING FEEDBACK...
@QuadTurboPrius One summer month later...
What is the feedback on your experimentions?
> Progress Roll-up...:
Chassis REBOOT is an effective short-term sanitization method. It evidences what performance delta is lost without it.
-- Less busy, faster network interactions enable this difference.
-- Flip-side...: slower bus detunes chassis response.
What is the feedback on your experimentions?
- What's your display Voltage/Amps like ?
- How many REBOOTS counts ?
- How many Miles driven ?
- What sort of power train response?
- What have you noticed driving City/Hwy ?
- What are your ECU/TCU pair up to??

TEST DRIVE REPORT
This weekend I did the reboot procedure. I had not done it for nearly two month. I had done single module resets.
Normal Reboot is still well received by chassis.
> Here is what I noticed:
-- The paddle shifters work each and every quick press instead of being hit or miss. I think this can be used as simple marker for "reboot needed" - Non responsive /goofy paddles** are pointing back to CGW being unstable.
-- Quiet pistons squirts under heavy accelerations near 4000Rpm. That is exactly-precise cylinders timings not only oil film padding everything quiet. Precise timings!
> The outcome is engine runs precisely & tranny shifts perfectly regardless of hot day at 75Mph freeway speeds.
Powertrain noticeably does not get lumpy with elevated idle when hot at operating temperature.
**: I have a reliably soldered SCM Module that host the paddles. The goofiness is external to SCM!!
From now on I'll use paddle to forecast reboot. Curious to see how quickly they will get impacted.

since unplugged 8months / 11k KM, i've never done anything in terms of "reboot" and my tranny seems goofy/spongy after the first 1-2 weeks of the unplug, recently i notice Start/Stop isn't working as expected, for ex. my car on cold start is usually in C mode and Start/Stop is activated so i drive until temps get in operated temp but start stop stays yellow with cross line, sometimes appears green (1-2 times) and then stays yellow, not sure why is that apart of that my voltage stays 14

ALT-LIN & ECO

You have "ALT-LIN'ed" 10k.Km ago and now your ECO Start/Stop is sometimes green sometimes yellow.
First paysr and celebrate lack of ECO but then it is a bit strange!!
--1-- I am surprised ECU let the IC-Display flag get green at all !!
It should just stay yellow for not ready.
It sounds like IC-Display wants a REBOOT! It is on seriously busy module taking to ESP across CGW.
--2-- Allowing a hot engine to cycle on and off in traffic is not my cup of tea. I like more cooling not more heat soaks. This is how engine heads get warped and head gasket breached by steaming hot coolant. Refrain from using ECO/Stops.
--3-- Since I've reprogrammed ECO to be set as previous, I have not had to bother turning it off again.
--4-- To resume ECO make sure all conditions are met. Experiment reconnecting ALT-LIN and clearing stored fault.
Usually batteries with significant drop-voltage during starter crank cause ECU to disable ECO. To help maximize battery health do a float cycle to reduce internal resistance.

There can not be a reboot with power remaining ON (oxymoron)... power needs to be disconnected:
Main AGM GND screw off
AUX AGM/CAP off

even i programmed it to be as prev. but I read that you Cali might recommend once twice a month to be switched ON for recharge during drive and then we can turn it off, that was the reason to enable start stop just to show green and then to disable it

DOING IT RIGHT
To REBOOT Chassis, all power need to be disconnected.
If not AUX acts as back up power for few VIP's...
That renders reboot near useless...
it's much like running MOD on 05W40 oil.... near useless

just to make clear it, I don't use ECO!

ECO is the FIRST FEATURE TO DISABLE and not look back!!
ECO roast engine heads, drains batteries and boils coolant.... not "the best or nothing"
