Self Tuning Help S63TU needed

[KClemente]

@Stokes not to worry, I've been tuning my N54 for the past 6ish years now but the transition from Siemens to Bosch is a bit jarring haha

I don't seem to have Characteristic curve for starting end speed at key start in any of the public xdf's for all the software versions I have.

The only thing keeping me from buying MHD right now is the fact that I would have to do a ton of map finding and map alignment. In the photo attached, I can't trust any of the burble stuff as many of the maps have seemingly incorrect breakpoints (the duration x axis) and the ignition timing maps all showing 0's.

What I'm hoping is that BM3 just has everything defined and I won't have to go digging thru the a2l or ols file. But BM3 is $200 more and only includes one free ots map.

Bootmod has something like 5000+ tables defined. I wonder if my stock rom was bunk to start with. Give them a shot and if you run into strange limits, import the mhd GitHub bin. If I spooled up to fast it'd shut down Target massively to like 160 load no matter what was happening.

i cant setup to exhaust valve stay closed in idle.

Mode 04 - should be the default mode value. (Table name: cwakr)

Mode 04

whats is the PID?

i have the Damos/OLS to find, if the MHD XDF doenst had

I added more details to my generic post.

I only know mode 04 because I had to figure it out for an N55. Other than that, I'm only guessing. Any reason the first cell of your codewort table is not 0 (default)?

 

[Stokes]

I just noticed something odd. What MHD XDF calls cwakr is not what bootmod calls it. I wonder if those override the default value of 04 for different settings like eco, comfort, sport, sport+? Also, I believe I had to invert the AKRxxx table calculations.

This ends up giving me closed flaps except for hard throttle in comfort and always open in sport. I inverted the calculation so I could think about it by throttle amount (100% to open in non-sport vs 0% or always open).

For N54 and N55 the MHD XDF have the table: Static Exhaust Flap Position = 0 open 1 closed


For the S63TU i cant find this table.
The CWAKR is stock. After the cold start, the valve opens.
Maybe have some code, like in Colum 1 = 00....change to 04. I dont know.

One time i coppy from X5M F8x and the valve works in reverse mode hahahahaha
in WOT the valve stay closed.
But in idle, no change.

I set the AKRGRCC and the valve close after the car move, like 0,5km/h

i know it is a shit stuff, but i like when work in N54.

The tables I posted are factory values from a S63TU F85 bin. Try changing these cells to all 00.

i use this and the valves doesnt open in wot, stay closed forever.
But in idle, no change. Opens after cold start

 

[bernardo774]

F9 = 249
0D = 9,75

 

[bernardo774]

X5M use a eletric valves.

M5/M6 use a vacum control.
If no power to the solenoid, the valves stay closed.

In N54 and N55E, without power in solenoid, the valve stay opens

I forgot to mention that there is nothing special available for the S63TU. No MHD+, no Bootmod custom maps. My F85 came with factory startup roar. About 0.5 sec open exhaust and 1200 rpm quick hit. When I moved over to the MHD bin, that was lost, so I found the tables and added it back.

I'll try and remember to get screen shots of the configuration options available for each platform next time I'm in the X5.

Hi I had a request, Ive been looking for weeks on a way to get better options for my f85 as I bought the MHD super tune without knowing it didnt come with any options such as anti-lag start up roar ect is there any way to flash a custom tune or a work around.

You could ask mhd to put the start up roar back. For some reason their tunes don't have it, but it was there factory for me. I copied the changes over and thought I posted about it here.

Been learning a lot on the mhd S63TU side and eventually will add more tables to the public xdf if mhd doesn't beat us to it. Guess we need to share more here or in a new thread.

i have some tune files and make a custom xdf to find the changes in this tunes.

also, i extract from psdzdata the M5 560, 575 and 600 cv tunes. Litle changes, but for trackday is a good point.
