... and pls ask them to UNLOCK MY ACCOUNT EDIT PRIVILEGE so I can consolidate the experimental solderless research I started years ago. I can't jump through hoops to edit words......

We can try to turn experimental research into practical A-B-C how-to instructions like we did to pull solenoid from top/bottom with/without dummy load...



SCM/ESP/EIS/MFK... are used to detune the performance of our chassis. We are not going to sit along expecting any recall -
We can organise data into knowledge to enable built-in awesome ECU+TCU operations for experimenters.


My last two solderless modules are side front radars. I wonder what more they are going to enable at this stage???


We Get To Pioneer... :

1. planted straight precise steering
2. vibration free engine
3. seemless responsive tranny
4. engine GDI pressure sentive torque
5. strong proportionally smooth brakes
6. oil cooled pistons with sealed rings
7. engine start-no-crank
8. clean 6kMi old engine oil
9. no-battery-drain ALT control (YoYo /TBD)
10. no-battery-drain while parked
11. almost forgot: normal oil pressure solenoid!
12. madness-free door keyfob
13. reliable LED HL
14. reliable TPMS
15. reliable rear/front short range radars
16. I forgot others... Im freshly jetlagged

Yours to enjoy experimenting for free.


ppl with T-Turbos and AirMatic are gonna find additional free extras!!

Sounds good.

We could use an easy install guide for the various platforms that includes a parts list (dummy sockets and covers for the things being unplugged). I know the S63 needs some things to be installed or a CEL will light up after unplugging. Perhaps other platforms require this as well.

W205C43PFL

Yes, apparently all the four cylinder MBs have the CEL and need the dummy solenoid connected.

According to the survey in the OP, no one with a M176 and M177 did the mod yet, I guess it is because it is too new and they don't want to try it until warranty ends.

Made it a sticky 😉

W205C43PFL

Much obliged : )

Random question, I have a tuned M278 (solenoid unplugged). In the warmer months, I use Molygen 5W-40. Would this be safe to use in the winter here in Toronto, or should I go down to 0W-40? The car won't be parked outside if that makes a difference, it'll split its time between a heated and non-heated garage.

W205C43PFL

not sure if it is safe but that is what I am planned on using, 5W-40 although I use Motul and will also try Pennzoil next summer.

Edit: That said, I remember reading that the car goes in normal pressure mode in cold starts anyways stock it is only after a while it goes back in reduced pressure mode. So I wouldn't be worried at all.

Unless you are expecting harsh winter this season in Toronto, 5W40 should be fine for a garaged car. However, recall to warm up to normal temperature before having fun.

I used to live in Waterloo, and -35C is on the very extreme I experienced in 16 years. Do not recall ever below -30C in town.

kistiyanpetrov

I can share a bit experience

I made this mode month and a half ago i was with 5/40 mercedes one, i notice gearbox get smoother and bit more tq at low rpms

1month ago i dropped the car in dealer for oil change and for some reason they put 0/40 while all the times it was 5/40 so i argue WHY TF they put 0/40 and is just because they charged me 400$ for the oil itself.. anyway

Now with 0/40 the car isn't like the 5/40 so def i would stick with 5/40 if the climate is ok with that im in europe and here the winter go -15/-20 and in the summer around 40

moe-idk

Thanks for all the replies, based on what everyone said I'll be sticking to 5W-40 for the winter. Also @juanmor40, I had the amg temp menu coded in to make sure I know when the oil is up to temp.

W205C43PFL

Funny that you mention that because I have a Calgary friend that has no issue either with 5W-40 for many years, yes slightly longer crank but that's it, the condition of his MBs are excellent, he does change the oil less around 8000 KMs though. So honestly, 5W-40 is more than fine in Toronto all year round.

Anyways so quick summary, the coolant temperature is doctored. The oil temperature is based on complex algorithms and is not the real time temperature as there is no oil temperature sensor.

CaliBenzDriver

We have noted early on the oil/coolant both warm up faster when pistons are sprayed to prevent heat accumulation.

OPTIONS ARE:
-- Thin oil raises spray above 2500.RPM
-- Solenoid enables spraying below 3500.RPM
​​​​​-- Best viscosity sprays near 1500.RPM.



Cold start benefits from parts being coated by lubricant - Listen to overall metallic sound from parts with thin film for the first couple minutes... this provides a reality check.


5w vs. 0w : no difference - After 2kMi a 5W40 has sheared into a 0w40 or 15w30 equivalent. Compare used oil analysis.


A high output turbo engines benefit from oil film with stable viscosity. You can definitely run MB stock 0w or 5w40 SAE-SN/SP lubricant in Toronto : we all absolutely agree and as long as it stays amber mapple-sirop, not black-tea.


​​​As @kistiyanpetrov just realized the engine ECU dislikes thin oil. The results are directly linked to viscosity selection. 15w40 is stable with controlled heat.

Winter is coming.

Who's plugging back their solenoid?

W205C43PFL

no one : )

Don't plug it back in, you risk jamming it and then starving the engine from oil as a result. Once it is unplugged, it stays unplugged.

CaliBenzDriver

Once any piston shaving stored by shut solenoid gets to jam nearby Cyl.1 squirter, the engine may be doomed without warning.

Earlier on, I advised against chancing solenoid plug-back before deciding to unplug.

---> Enabling *normal* pump output is best experimented safely as a one-way journey.

I don't know of any benefit to restore limited pressure. Can it be done: absolutely.

W205C43PFL

Wait... so you are supposed to overfill the engine oil if you rev the engine to redline constantly or do Italian tuneup every day?

w1s

​​​​​​​So the safest way would be to change the solenoid? Changing oil does nothing right?

Just wondering my winters are "hard" -10°C haha

CaliBenzDriver

@juanmor40 just posted above that 5w40 oil works well at -35°C...


-10°C is no problem. When engines are driven temperature gets regulared to near 200°F regardless of -10°C outside.

If you wanted to "plug back solenoid"... replacing solenoid would be expensive but safe option as well as replace/clean oil filter CAP that has a bypass valve known to store junk.

w1s

The cold start is worrying me. I use 0w-40 anyway.

CaliBenzDriver

nice, that is an "MB approved" lubricant.

kistiyanpetrov

Can you advise me what oil i should put in when i do my 8k km on the current 0/40, i would change it tomorrow as it is on 1500km already but since i paid 400$ for this oil i would keep it for now..

Till now i was driving only with Mercedes oil but since i do it every 7-8k km I can change it at least once before my service interval is due with something else

I read that you are happy with Mot 5/40 if im not wrong (if so can you recommend which one to take for best results as im driving more racing than normal), so should i go with that and if so can you tell which one I find online that there's Motul 8100 X-cess and X-cess GEN2 both 5W/40 SAE thank you

CaliBenzDriver

How many miles as your engine run on stock 0/5W40 ?
how long since unplugged??
