There are some videos out there. The one from FCP is good. I tried hard to do it right and I had no issues afterwards at all. ///Rich |

At this point I don't know if I should care or not. Upon inspection they found no issues and the car drives and shifts great with a few hundred miles post-service. Then looking at other forum postings, where people have claimed there is a whining noise with their ZF, I have not seen anyone say there is an actual issue after taking the car to the dealer or other shop for inspection. Maybe some of them just whine?

Recently came across this gas station that is about 15 minutes from my house. This place is a tuner's wet dream!! Perfect for my fill ups where I do 4 to 5 gallons of E85 then the rest 93 octane. Haven't tried the E30 blend yet.
Also, got a car wash, mist and shined, cleaned the wheels, and shined up the tires.

You already run 10% ethanol in your car now with Unleaded fuel = E10. Unleaded fuel has had ethanol mixed into it since the early to mid 90's I believe. Some countries now run a minimum ethanol content in their fuel of E20-E25 standard (Brazil?) In a nutshell the higher the E mix/content in your fuel, the higher your effective octane level. The 91-octane unleaded fuel in CA and in the SW is not what most other states get with their 92 and 93 unleaded available at their pumps. This is where we can up our octane level to help with timing advance to obtain more power but keep in mind your Stoich AFR will be off since your car's DME doesn't know you're running more E than 10% and it needs to be tuned to account for it. Downsides? Other than having to tune for it downside to running more ethanol would be that your gas mileage will suffer some. Ethanol contains about 30 percent less energy per unit volume than gasoline. So when you tune for it part of the tuning process will require more fuel volume. And our fuel pumps aren't designed to run such high volumes through it when tuned so this is why many get a TU pump to run E30-E40 mixes in our B58. Another downside is the few who run high ethanol mixes tend to have some cold start issues when it's very cold out. The motor turns over more before it starts. Not a big issue really, just an annoyance. And there aren't very many stations around depending on where you live. I live in North OC and there are three stations within a few miles of my house so not an issue for me. |

The other poster, Jv92Red, summed it up pretty good. My main thing is the lift in octane from ethanal allowing for a more aggressive tune. I also purchased and installed the TU high pressure fuel pump (from the 2nd gen B58 motors) to better support the ethanol blend I like. With the weather getting colder here in MN I will be shifting to 93 octane only and detuning the car until spring.

Do you think that the AFR in my logs is misrepresented since I'm not using the ethanol maps?

one thing to look out for is your fuel trim. check out the STFT (short term fuel trim). the car DME can only adjust up to +/- 30 percent, so if you exceed that, then you're not getting the targeted amount of fuel (for the tune's AFR). this is important because ethanol is less power dense than gas, so you need more ethanol than gas per unit of energy. in other words, if you're maxing out the fuel trim, then you could be in a position where the DME wants 'x' amount of fuel to hit the target AFR, but can only give 'y' amount (y is less than x). THEN, you could be running a lean condition (as compared to the target AFR).

Here is a recent log. Do you want to take a look and provide an opinion? The STFT ranges from 5 to 9 during the pull. Not sure what to make of that. https://datazap.me/u/jmclellan/pulls...a=3-6-16-18-26

speaking just about fueling and the fact that you're using a few gallons of ethanol while running a gasoline tune, you're STFT is very much acceptable. now, if i were to compare to BM3 n55 93oct tunes, i'd say that you have more boost, more advanced timing, and a leaner AFR. all of this doesn't mean much since we're on different engines.

Hey Everyone.. new member..
I own the 2016 blue 228 vert. Has 44,000miles. Pretty base model. No heated seats or steering wheel, hifi audio, base suspension, no xenon. Bought in February 2022.. I put a ton of miles on my cars and now if I trade it in I'll lose a bunch on what I owe on it vs my trade in value on the silver one I'm looking at this 2016 m235.. xenon lights, anthracite roof, Harmon kardon, heated seats and steering wheel, m suspension...etc, 15,500miles. I would have to come up with $9,000 to buy out my car. Do you guy guys thinks it's worth it? (I know, only I know., but would you do it?) I can totally justify it to myself on one hand and then the frugal person in me doesn't want to spend the $9000 to get another car.. but I CAN afford it...but do I want to??? Anyone have any thoughts? Last edited by RyanGphoto; 10-11-2022 at 02:42 PM.. |

But in either option you would be paying 9k towards your current car.

My wife doesn't care. She wants me to be happy, I work hard and don't really blow money on things. This is a serious luxury for sure, but affordable. It just feels wrong to write a check for $50k+ for a 2016 m235 convertible (after fees and cost of car etc) Thanks for all responses. Ryan G |

It isn't what I did to my 2-Series as much as what was done to it: I just got my car back to pre-accident functionality when this happened - someone parked next to me, hit it, and took off. I swear my car is cursed.
