Don't know, as far as a "BM3" tune is concerned.

That's why I ask??

Albeit, the track is practically at sea level.

Just flashed the cs+ map and am really impressed with the drive ability, throttle tip in is no different to oe, the whole tune feels factory, there are no issues with drive ability at all

I could feel more pull from midrange up, nice linear feel right to redline

I saw a beta cs+ map with note of improved throttle in sport+, I assume this is scaling back throttle tip in, but I don't think you need it tbh

I'll give the stage 1 map a go soon, but I suspect as with other tuning platforms I've tried, the more power you add, the more sensitive the throttle becomes and harder the car is to drive smoothly

I'm also wrapped that the burble is working properly, I had issues with both bpm and oft where the burble maps were switching, where sport was louder/more aggressive than sport+

Is there any way to get burble without having asd enabled? I had to go in and enable it otherwise burble wasn't working. What if I then coded it off again with BimmerCode/Carly?

I, personally am not in love with factory/stock ("oe") ZCP Throttle response.

There is too much (If this is what it means?) "tip in".


Cheers!

Stage 1 is smooth and addicting. You can customize the torque in 1-6 gears. Try it you'll like it.

Does having the ability to adjust the torque within gears = a change in throttle response?

[TrueNorthM5]

I've run Stage1 93 all summer.

Going back to CS tune for the winter.

I found throttle feel to be as good if not better on the BM3 Stage 1 tune. Perhaps part of it is the GTS DCT flash which seems to help with both smoothness and shift times too.

It prevents spinning the tires off in 1st and 2nd 😉. I think the throttle response is very smooth. If you have a manual, it shifts WAY better since the rpm's drop between gears like they should.

Agreed the throttle in sport+ moving off from rest was vastly improved when I flashed cs trans with thor

I'll give the stage 1 a go today

What's the consensus around boost limiting, 20 1st and 10 2nd?

[jmciver]

For PTF, do you have any plans to add direct ENET cable interface support for iOS or Android phones, thus eliminating the need for the OBD Agent when using a cell phone/tablet with BM3?

I have noticed that more BMW car app makers now offer a direct interface using an ENET cable as a connection option. For either iPhone or Android, you would still need a lightning to ethernet adapter (iOS) or a USB to ethernet adapter (Android) - both of which are available and fairly inexpensive adapters. I am not a software engineer, but I would think modern/current iOS or Android devices would have the necessary processing power to perform the functions of the OBD Agent when combined with the correct adapter to use with an ENET cable. While some may prefer the current wireless connectivity option via the OBD Agent (especially those who like to run the BM3 app routinely while driving), I think having the option for a direct wired connection to your device with an ENET cable would be good to have as well.

Would really like an option for a built in 2-step/No lift shift for us manual guys. Companies like cobb offer this with their tuners. It would be great to see something like this added. I did email PTF about it and I believe its something they are looking into but more interest might push it higher on the list.

Sounds about right for a stage1 Map. You'll still probably get some spin in 1st and 2nd even with the boost reduction, but it certainly helps.

Interesting...

Could you please elaborate.

A 2-step (basically launch control) allows you to set a rev limit value that is activated via the speed sensor and clutch. So at a stop, say at a drag strip tee, you can build a small amount of boost but a better launch.

A no lift shift, is exactly what it sounds like. Allows your to engage the clutch and shift without having to release the throttle. Its achieved by the ecu controlling things like throttle, ignition, and fuel during that short amount of the time clutch is engaged.

Ok., - Still lost here - So, how would this (be applied to) work with a MT??

ZCP and even non-ZCP oem maps tend to be twitchy on tip-in as well.

Going into Diagnostics and resetting adaptations can help some of the smoothness as well.

Typically people will do 30 in 1st 20 in 2nd but depends on your tire setup, surface and ambients.

Yep but you can already use a wired connection with the agent. ENET cable to the agent and then USB from the agent to the mobile device, iOS or Android. Adding a direct ENET cable connection is in the works as well across all systems supported (iOS, Android, Windows, macOS) and a number of other features.

If you view any datalog you'll see a "Download CSV" button in the top left corner.

yep, features such as these aren't available in the OEM software and custom changes are required. Changes such as these take time to develop and sort of inject in the OEM software but we're working on them

2-Step: The computer takes in the input of vehicle speed (0) and clutch engagement. You can then smash the gas and itll rev to a predetermined rpm set in the tuning software. Exactly like launch Control

No Lift Shift: The computer takes in the input of vehicle speed (XX) and clutch engagement and TPS (WOT). You can then shift with out lifting off the throttle and avoid damage due to the computer controlling inputs for the duration of the clutch engagement.

Watch some videos on Youtube regarding 2-steps. Itll clear everything up.

any chance you can flash tune using the obd wifi modules on market - as used with bimmercode, thor, etc

Most OBD WiFi modules you can come across out there say eBay/Amazon (e.g. ELM327 WiFi) are inadequate. While they offer WiFi connectivity from the phone to the adapter, they talk over CANBus/DCAN/KLINE through OBD. That's far slower due to slower data throughput than Ethernet/Flexray setup that bootmod3 uses. Can't comment on other apps/products as we don't have experience with their implementation details.

Agreed, Ethernet will have the highest speeds... and well done to PTF proTUNING Freaks for choosing and retaining this platform.
Removing the need for an Agent hardware will be a great move - direct connection from an iOS or Android device will be fantastic.
