You are looking at it wrong an OTS product should work for everyone just fine. If you want ultimate performance specific for your car etc then you need an individual tune (not the other way around). Why would a 93 OTS tune constantly pull ignition on 93 etc. These are not complete files they are providing a starting point for a tuner and/or individual who likes to tinker (log etc.) it is by no means a set and forget software

And again, you deal with the same thing on the stock tune. Our cars run more effiently on 93 because it's above the minimum octane rating. Running Cali 91 will make less power, less gas mileage, and pull the same timing that it does on the BM3 tune. Except PTF made a new map to compensate for the crappy gas. When will BMW do that? I ran logs just for peace of mind and had no timing issues until recently. There are plenty of people that their logs are clean. But it's your responsibility to verify it's good, just like with any other aftermarket part you install. It requires attention and maintenance. |

OTS maps do exactly what they're intended to do....they give you an off-the-shelf tune that will work well for every car. They're not perfect tunes designed to squeeze every bit of hp/tq out of the car, that's not safe. They're usually on the conservative side for that very reason. That's also the reason there are constant revisions to each OTS file. If you want a "perfect" tune, you need an individual one for YOUR car....but even that will vary depending on the environment your car is in on any given day. |

While I understand that the effect vary by temperature etc and that the ECU adapt I think that “you should regap “ shouldn’t be needed to a OTS tune and be reserved for custom/more aggressive solutions. Same with logging ... you can’t expect a normal customer to log data and maybe even pay extra for being able to do so. Sometimes the tunes read as if they are in a Beta stage .....
Oh well I don’t have to get them until all problems are shaken out |

I've had Stage 1 93 on my car since the week PTF released it and I've had no issues with my plugs (and I'm at 22k miles). Others like kern have had to adjust theirs with way less mileage. It 100% depends on the car....brand new, broken-in, or high mileage....doesn't matter. No OTS map will ever be able to take that into account, and they're not intended to. Their intent is a "fit for all purpose", which is never perfect. |

Yeah it's been on my radar for the last couple of months, but I decided that I like the way the market looks for the M3 ZCP so I've been shopping those. I'll be trading in the 340 once I find one, haha

I don't think you understand fully how the tune works in stock or modified form based on your concerns. Your car is pulling timing right now in certain situations and you don't know it. Hot days, bad rounds of gas, clogged intake filters, etc. all are a part of the daily routine that affect how your car operates with the same tune. Not to mention adapting it across 1000s of vehicles across the world. Your car does a lot of the logging for you and changes parameters on it's own. All PTF did was allow you to see more of what's going on when you want. If you never want to log, you don't have to. Most of what you see is not going to blow your engine. You're getting feedback from enthusiasts that want to go the extra mile to make sure everything is purring as perfectly as possible, as often as possible. You'll never see a tune with "all the bugs worked out" stock or otherwise. I mean, hell, our cars run 14AFR to redline in stock form. That's ridiculously high. But BMW is more concerned with efficiency and gas mileage, not power. |

I totally understands how an ECU works, but some of the tunes on the market today look like BETA versions / pre-release versions / ... to me as I think a) the tuners rushed to get them out once the ECU was cracked and b) seem to be into the "my gains are higher than yours" game and c) listening/waiting for user feedback/logs to finalize the product.
BMW is certainly not worried that an AF of 14 might not be optimal for power. They decided on the power level the car should have (distance to M3 etc.) and the car always reaches the goal, so why go for more power. The only problem with AF14 is temperatures/running lean but I'm sure they tested this for reliability. Unsubscribed/ |

Now resorting to personal attacks .... grow up. Not everyone has to agree with you. It's a free country last time I checked.

Forgot to post in here, but I started a log review thread. I just want to compile as much data as possible so we can have some good data visible to everyone. It's not limited to BM3 but I am focusing on OTS tunes since custom tunes add a lot more variation. Feel free to post up and join the discussion.

I saw someone post this somewhere random and it was just because of burble having to do stuff. Try turning off burble on the map and reflash and see. I don’t have this issue and I have a manual as well.

I'm actually stock currently, shopping around for tunes. Wondering if the BM3 has this already built in, since you don't feel it? Did you feel it when you were stock?

I have the this kind of bog between shifts rarely, actually I felt it twice yesterday. I also have rev hang between gears more often. I wonder if the on decel aspect of the burble mixes up the throttle somehow .. could be related. I'll kill it tonight and report back in a couple days. |

Ran another Stage 1 e30 log, this time the mix is closer to e35/e40. I'm still seeing some timing pull on cyl 1.
I'm going to do a leakdown test soon to see if my headgasket is good. If that's the source of my coolant loss and i'm just getting some coolant in cyl 1 that's messing up the octane, then that'll be two birds with one stone (since BMW refuses to diagnose my coolant loss). Going to message PTF support as well to see if they give a recommendation other than running the ACN map http://www.bootmod3.net/log?id=5d7a241ec090c677bd368625 The car still pulls hard. I like comparisons so I raced a buddy this weekend and pulled on him pretty hard. His 435 is xdrive/8AT/Stg 2 E30 vs my RWD/6MT/Stage 1 E30. Pretty cool to see how the performance compares but I'm looking for a RWD N55 for a better idea. |
