Show Me Your Throttle Maps

[Tbonem3]

Most of us can only make changes with Martyn's tool, mind you Brian.

Guys, what you're changing is only half of it! The other map you should be tuning is KF_MD_FAHRER or Driver Demand Torque (8x6 Map; Euro & CSL 0x8298 RPM; 0x82A8 %-pedal position; 0x82B4 %-torque).

OVERVIEW
"The driver's request is determined by the PWG module in the form of a relative pedal position "pwg_soll", where 0% corresponds to an accelerator pedal that is not actuated, 100% to the full throttle stop of the pedal. This relative pedal position is converted via the map "KF_MD_FAHRER" into a relative driver request "md_fw_rel", which in turn is between 0 and 100%. 100% corresponds to the maximum effective torque "md_e_max". 0% corresponds to the drag torque with hyperbola boost "md_e_schlepp_hyp" (without consumer)."<---------- (doesn't include drag torque from accessories like AC, alternator, H2O pump, engine drag, etc.)


Here's mine for comparison, but don't go too crazy or you'll start throwing error flags and EML lights because torque values aren't jiving!

I have been driving with a nearly linear throttle for a few weeks now. I certainly like the improvements that have come from bringing up the initial throttle response dip that exists in the stock comfort mode, but I can now see why there is an increase in response/a curve in the middle as it feels a bit flat. I will be making changes and post up what I get once I am completely satisfied.

Overall I livened up the initial throttle tip in for clutch uptake in comfort mode and dumbed it down because it was too aggressive in sport mode.

I brought my laptop out to look at an E46 today so I figured I'd take a picture of my maps. I'll post pictures and tell you pedal to throttle percentage. The first number will be physical pedal percentage and the second will be commanded throttle to that percentage.


Comfort:
1% : 0
5% : 2
10% : 5
20% : 15
30% : 24
40% : 33
50% : 43
65% : 50
80% : 57
100% : 65

Sport:
1% : 0
5% : 6
10% : 17
20% : 29
30% : 46
40% : 59
50% : 74
65% : 85
80% : 92
100% :100

Hey guys,

I'm totally new to coding/tuning and just stumbled onto this thread. My car has a custom TTFS tune and retrofitted M-Mode (if that matters) and I've been wanting to fine tune my Comfort setting to improve the initial throttle response a tiny bit (Sport is too twitchy on initial throttle and dont like that its 100% WOT at only 3/4 pedal travel). Like I said I'm completely new to throttle tuning, is it possible for me to tweak my Comfort throttle map? Total noob here hoping I can be enlightened 😊

If ttfs locked your bin then you'll have to go back to them. If you're able to read the bin file using BMWFlash then you'll be able to change it yourself.

When I pushed the Sport button, nothing happens. When I say nothing, I mean the throttle response is exactly the same as Comfort. I thought my Comfort mode and Sport mode were set to the same parameters, but they aren't. It's like my Sport button isn't activating the Sport map. I push the button and the light comes on, but nothing changes. Have you ever heard of this before? If so, how do I fix?

Never seen this before. Post your bin?

I am new to coding, have successfully retrofitted M-track mode and am wanting to adjust the throttle maps and aux. fan table. Which programs are being used to access the throttle maps?

I understand it is a total noob question. Please feel free to publicly shame me and delete this post if you’d like

I use TunerPro with the XDFs from the github repo here:

I did something interesting with my throttle map. I set Comfort to max out at 65% throttle. It saved me gas and made me actually make a conscious decision before flooring. The power wasn't there until I pushed that Sport button. An addict regulating the addiction...

i did it on mine too, thanks for the putting the idea out there!
