Got rid of that 2.0Toy *check*
Got a ZF transmission (like Acura, well somehow) *check* Good for you. |
Is that a good thing, or a bad thing?

That tranny belch is dope! |
You know what shifts like fucking butter? My Volvo...
hmmm...I guess it's not the ZF? The Aisin AW F8FXX series is the world's first 8-speed automatic transmission designed for use ... It is also called the TG-81SC (Volvo), AF50-8 (Opel/Vauxhall) or AWF8F45 (Cadillac). ... 2015–2018 Volvo S60 II; 2015–2018 Volvo V60; 2014–present Volvo XC90 II; 2016–present Volvo S90 II; 2016–present Volvo V90 II ... |

Our B&B for the F1 race was on 2222 just outside 360, fun roads out there. I've started disabling auto stop in mine, unless I know I'll be stationary for more than a few seconds. Just too intrusive. |

I'm programmed to turn off auto off in both my work truck and Volvo...

I turn it off so seldomly I have it on by default. I get pretty decent mileage and it definitely helps
It is still unknown how much additional wear and tear that Auto/Stop Go thing would have on your engine in long term. IMO the 1 or 2 MPG you saved is not worth the risk. You know, Audi does not care about your engine the moment the warranty expires.. |
I guess I should try leaving it on although Scotty Kilmer says not to

You know, Audi does not care about your engine the moment the warranty expires.. Depends if you believe this source is real https://www.greencarreports.com/news...r-cars-starter (1) The gear ratio from the starter-drive pinion to the flywheel ring gear is optimized to make the starter's motor turn more slowly. This can be done without materially changing the design of the transmission or flywheel at all on existing designs. Crucially, this reduces starter-motor speed (in RPM), since 90 percent of starter-motor brush wear occurs not during cranking, but during the coast-down after the start has finished. If a higher-torque motor can spin more slowly, its coast-down time is shorter, increasing its longevity. (2) The composition of the carbon and copper brushes on a start-stop motor differs from its traditional counterparts to increase longevity without accelerating the wear on the commutator. (3) Rather than rely on oil-impregnated bushings for the rotating assemblies, start-stop starters mostly use needle bearings. (4) The solenoid on start-stop starters decouples the mechanical action of engaging the drive pinion into the flywheel from the electrical action of stopping and starting the motor. This allows for a dedicated design to turn power on and off to the motor, optimizing contact design and wear, against contacts that have to be integrated as part of a spring-loaded plunger. This also reduces the electrical load requires to turn the engine, so that there is enough current available for accessories/lighting to operate during the start event. (5) Finally, start-stop motors are integrated with other technologies that identify when each cylinder of the engine will reach top-dead center. |
I can identify so many loop holes in that report. I still believe only time will tell. But even when there is issue down the road, how can we relate those issues with Start/Stop is another issue by itself.
Just to name a few: That report is obviously biased... since they are a Green report, they are for all things "green" 2nd. Even if i believe this is true, then all Honda engines are going to be dead a lot sooner If a higher-torque motor can spin more slowly, its coast-down time is shorter, increasing its longevity. |
I am no engine expert.. but for what it's worth here is what i googled :D
https://www.autocar.co.uk/car-news/n...r-car-s-engine Disadvantages of stop-start technology:Does stop-start wear out my engine?When it comes to durability and long life, all the bases relating to the starter gear itself should be covered, but the higher number of stop-start cycles lead to increased engine wear unless steps are taken to prevent it.“A normal car without automatic stop-start can be expected to go through up to 50,000 stop-start events during its lifetime,” says Gerhard Arnold, who is responsible for bearing design at Federal Mogul. “But with automatic stop-start being activated every time the car comes to a standstill, the figure rises dramatically, perhaps to as many as 500,000 stop-start cycles over the engine’s life.” That’s a big jump and one that poses major challenges to the durability and life of the engine’s bearings. A fundamental component of the engine and also one of the heaviest is the crankshaft. It’s supported as it spins by a number of precision ground journals along its length running in ‘plain’ main bearings (no ball bearings or rollers, just smooth metal). These are the main bearings and the effect is greater on the bearing at the back of the engine immediately adjacent to the starter motor. When the engine is running, the crankshaft and main bearing surfaces don’t actually touch, but are separated by a super-thin film of oil, fed under pressure and pumped around the bearing surfaces by the action of the spinning crankshaft. This process is called ‘hydrodynamic lubrication’ but when the engine stops, the crank settles onto the bearing, the two metal surfaces coming into contact. How rust helps to prevent wearWhen the engine starts, there’s a point before the two surfaces become separated by the oil film called the ‘boundary condition’, where the crankshaft is spinning, but there’s metal-to-metal contact between the bearing surfaces.This is when most wear takes place. Fitting stop-start means the boundary condition (and metal-to-metal contact) could exist perhaps 500,000 times in the life of the engine instead of 50,000 and normal bearings would wear out long before that. Two things prevent that happening. The first is that bearing manufacturers are developing new bearing material with greater self-lubricating properties to resist wear on start-up. Federal Mogul has developed a new material called Irox with a polymer coating containing particles of iron oxide (rust), which in this microscopic form is surprisingly slippery. In fact it’s so slippery that the coefficient of friction of an Irox bearing is 50 per cent lower than a conventional aluminium bearing and will easily last the life of an engine equipped with stop-start. Low friction oils help prolong engine lifeThe second is improvements in lubricating oils. A modern engine oil contains an additive package comprising a complex chemical cocktail. The technical director of UK company, Millers Oils, Martyn Mann, says the formulation of these packages are critical: “We’ve reduced friction with our oils and improved durability of the oil film and we think that has to be the way forward with stop-start systems.”Millers began researching low-friction oils in its laboratories back in 2006. “We put a formulation together, tested it on a friction rig and found we could reduce the sliding friction between typical components like pistons and liners by 50 percent,” says Mann. stop-start systems.” Millers began researching low-friction oils in its laboratories back in 2006. “We put a formulation together, tested it on a friction rig and found we could reduce the sliding friction between typical components like pistons and liners by 50 percent,” says Mann. Generally, this reduces heat, power loss, fuel consumption and wear but Miller’s new triple ester nano-technology, known as Nanodrive, goes further. Tiny nano-particles like microscopic ball bearings exfoliate under high pressure, the polymer ‘flakes’ adhering to the engine surfaces. So far the technology is available only in Miller’s high-end racing oils, but in relation to stop-start, it could also reduce wear during each re-start when the most wear takes place. With low-friction bearing and lubrication technology in place the potential threat to engine life by stop-start systems should theoretically be overcome. But the current technology is still relatively new and only time will tell whether every car manufacturer has got it right. |
But obviously that is not the reason why i disabled mine. You know... BMW drivers needs every .01 sec to beat everyone off the line at the light.... Auto/Stop just get in my way. :rofl:
|
especially with drive by wire and turbo lag :annoyed:
|
Actually, with a combination of Sport+ and the Sport Auto.... off the line is not an issue. If anything it is too sensitive and jumpy......
I usually experience the "Hurry the fuck up, where is the power?" type of turbo lag when i go from cruising to pedal to the metal... that is when NOTHING happens :rofl: |
I think when Yumcha get his... you Ass 4s could get together and have a cuck party
|
Funny, now that you mention it, when I do something called DTSC Off and Sport mode, she moves alright...there's even a little extra tap of the gas at the very end that UNLEASHES an extra 10 ft/lb supposedly :rofl:
|
in my EB F150...it's a pig unless I'm in sport mode...
|
From what i heard... every car's sport mode feels different. I heard Lexus's does nothing :D
Have not had the chance to try the new Audi's Turbo yet.... does your brown A3 have sport mode? :D Wait, you also got an F150? how many cars are you hording now? |
LOL...F150 is my work truck, it's a '16 I've been driving for 2.5 years now.
A3 is Manual but I will say for a little 2.0t it's a peppy little turd! Especially when I pulled the catalytic off and opened up the exhaust some. |

I'm sure you know this. But besides the button on the dash, just keep it in Dynamic mode and it will disable the start / stop.. Problem solved..LOL |

Even with hooning up/down 2222 & City Park Rd, and lots of idling to get in/out of COTA, I still averaged 27mpg round trip. |
I dont know how you guys get 27... 30mpg... i get 20.2 and that is with 80% freeway..... with average speed of 20mph.

You keep forgetting to put your car in helicopter mode and flying over all the traffic jams :2cents: |

I get 33-35 just cruising on the highway. If you really hoon it, you'll be in the teens pretty easily.

Shifts before 3.5k rpm, lazy throttle response, 90's era gear changes, no juice. Comfort: Little more power but still lazy throttle and the suspension is at old Caddy levels with less wafting. Gear changes are pretty lazy still. Normal: What I typically use, good power, still comfortable, normal throttle, quick but not rapid gear changes Race: Razor sharp throttle, DSG will slam gears in with the awesome DSG farts, suspension is noticeably stiffer, exhaust louder, etc. Individual: Whatever combination of the above you want. |

I rarely shifted it in "S" mode in the S4, dynamic was pretty good, but it's a different animal when in S mode. Now with wife's SQ5, I only drive in S mode, D mode just doesn't cut it. I think the S4 really spoiled my driving experience with any future Audi my wife gets. Do you have the Sport seats or S sport seats? |
