All he has to do is change to the values I posted no need for any calculations.

You do not need a spreedsheet. Simple.

Default Re: Small idle issue on E36 S54 - low speed / low load clutching

Ok guys there's been some confusion so I'd like to clarify before flashing.

Here what I've done

⦁ K_SKRAFTS_CONTRO: was 1.00 Changed 0
⦁ K_V_CONTROL: currently 2.00 unchanged
⦁ K_V_WEGIMPULSZAHL: was 23830 changed 4563

⦁ K_S_GANG1_NV_MIN: was 123.5 U/khm changed 135.3
⦁ K_S_GANG1_NV_MAX: was 131.5 U/khm changed 143.9
⦁ K_S_GANG2_NV_MIN: was 72.5 U/khm changed 81.9
⦁ K_S_GANG2_NV_MAX: was 77.5 U/khm changed 87.6
⦁ K_S_GANG3_NV_MIN: was 47.5 U/khm changed 53.6
⦁ K_S_GANG3_NV_MAX: was 52.5 U/khm changed 59.1
⦁ K_S_GANG4_NV_MIN: was 35.5 U/khm changed 40.6
⦁ K_S_GANG4_NV_MAX: was 38.5 U/khm changed 44
⦁ K_S_GANG5_NV_MIN: was 29 U/khm changed 32.9
⦁ K_S_GANG5_NV_MAX: was 31 U/khm changed 35.2
⦁ K_S_GANG6_NV_MIN: was 24 U/khm changed 0
⦁ K_S_GANG6_NV_MAX: was 26 U/khm changed 0
⦁ K_S_GANG7_NV_MIN: was 109 U/khm changed 0
⦁ K_S_GANG7_NV_MAX: was 117 U/khm changed 0

⦁ K_GANG_GRENZE 1-2 was 96.5 NOW 107
⦁ K_GANG_GRENZE 2-3 was 61 NOW 68.8
⦁ K_GANG_GRENZE 3-4 was 43 NOW 48.8
⦁ K_GANG_GRENZE 4-5 was 33 NOW 37.6
⦁ K_GANG_GRENZE 5-6 was 28 unchanged

⦁ cfg_m.getriebetyp Currently 3 unchanged
⦁ cfg_m.getriebetyp Currently 3 unchanged

⦁ 0x6 Currently 20 changed 08
⦁ 0x8006 Currently 20 changed 08


⦁ Cfg s.baureihe Currently 32 unchanged
⦁ Cfg m.baureihe Currently 32 unchanged

⦁ KL_LAA_N - Adaptation Multiplictive load activation map
RPM values 1K 3k 4K 6K 10K
All RF values .30

questions.

If my right rear speed sensor is going to the DME at X60004 pin 22 what should K_V_CONTROL be? Does that count as direct or is that something else.


I used 3:91 for my diff and 245/40/17 on the spread sheet. Since I am a 5 speed, should I zero sixth gear or leave it alone. I DONT have a gear position sensor.


In another thread Terra said 0x6 and 0x8006 can be changed from "20" to "08" to put the DME into "E36 mode" will this contradict anything?

Lastly, KL_LAA_N, confirm that IS the mad to set the adaptation active on at .30rf and under?


Thanks!

For your problem as described, change the following the rest is irrelevant.


K_V_CONTROL - 0

K_V_WEGIMPULSZAH - 4563.00

K_SKRAFTS_CONTROL - 0

Reset adaptations

In this context, direct means the DME determines its speed based off a square wave signal fed directly to it vs getting the speed information from the CAN-bus. You do not have an E46 ABS/DSC module, so you are not getting that information from the CAN-bus. Set K_V_CONTROL to 0.

Leave the 6th gear values alone. It won't do any harm leaving them.

E36 mode makes more sense for an E36 I think.

I'm not sure what you're asking about KL_LAA_N

Thanks for the explanation, that makes sense. I was confused on the direct vs "from ASC/DSC" because tehnically my signal is coming from the old E36 ASC. I realize now that in its current state it's not over CANBUS, rather it's a direct line just coming from the ASC, that's all.

I left the values for gears 6 and 7 untouched so that is fine.

As for E36 mode, yes that makes sense. I was told doing that could possibly disable the sport mode button, but I am okay with that, I never use it anyway, I prefer the stock throttle mapping.

As for the KL_LAA_N. I got that table from your adaptations thread in the first post as an alternative to fully disabling the adaptations. I didn't want to fully disable adaptations, rather have them active up to .30RF. That is the table you edited for that correct? If it is, I mimicked the changes you made for the same result. It appears that's the most reasonable way to approach adaptations vs tuned maps for optimal economy and performance.

Flashed the car, it would not idle at first. Throttle blip allowed it to hold at about 50 rpm on its own.Sport mode is also disabled.

First move will be to take the DME out of E36 mode and reflash. I’ll report back after that’s done.

Removing E36 mode showed no change.

Then I did my old binary with only

K_V_CONTROL - 0

K_V_WEGIMPULSZAH - 4563.00

K_SKRAFTS_CONTROL - 0

and that also had no change.

After those failures, I flashed my old working binary from just before this thread and the car was back to normal.

After that I flashed my working binary with just K_SKRAFTS_CONTROL to 0 and found the car behaved like shit again and would not idle. So that was the culprit. Still working on some things - will report back

Disconnected my HFM and found the car idles completely fine. Got an HFM code after a drive though.

I ordered a new one and installed it along with

K_V_CONTROL 0
K_SKRAFTS_CONTROL 0

Then reset adaptations. Everything seems great right now easily 80% better IF the E Fan is on the car may miss the idle catch immediately, but it grabs and evens out.

Why would HFM disconnected / Alpha N be completely rock solid w ZERO issues vs HFM connected and sporadic issues at times?
