M3 E46 CSL Clone with Intake manifold pressure fault - 0000DF

I'm not super familiar with the SMG so double check that as far as settings go w/others. Looks like you read a bin, pretty close to being done, that program sure is handy.

The one thing i felt it should be ticked is the "Disable requirement for GPS after SMG to Manual conversion?

you need the option DISABLE REQUIREMENT FOR GEAR POSITION SENSOR checked in conjunction with the other option in the other page that says CLUTCH WIRED DIRECTLY and you need to make sure you are using either black or brown clutch switch that has part number ending in 700

for the internal map sensor issue, ECUWorx does not handle that nor can it see/edit that value. it needs to be checked/changed/confirmed with a HEX editor

on a CSL tune it is found here

• Pressure scaling: at 0xC476 change "D3 1C" to "C2 5F"
  • MSS54s have a different barometric pressure sensor than HPs, this changes the sensor's scaling to have the CSL software work correctly with the non-HP sensor.

for a NON CSL HP tune file its differnt but looks like you have a CSL tune file so the above is what you need.

I have the BMW tools software from EcuWorx since before.
What HexEditor do i need? Or can i just read the DME with WinKFP and send it to anyone who can check it? I dont really feel comfortable to change and mess things up
Or someone can connect in Teamviewer and check it out?

Hi, im looking at the Binary read in Hex Edit from earlier but i cant even find "Pressure scaling: at 0xC476 change "D3 1C" to "C2 5F" Dont really know how to search for it. Any tips? Like on the picture?

If that screenshot is from your computer showing your tune file then you did it right. You found the right address and it looks like it's already set to c2 5f

So if that's the case, the code is correct in your tune file.

At this point I don't know what else to look at or think of unfortunately.

[Jeppe1976]

Actually it was not C2 5F before, i changed it for the screenshot 😀. But a little scared to write into DME not knowing if i screw things up?

Original readout it was "D3 1C" no clue at all what that means.

And if i check the ambient pressure with a diagnostic tool it is 995 (in cm) and does not change if i unplug the External MAP sensor - so i guess its the Internal MAP sensor showing?

This does not make sense. You had D3 1C originally? If so then it is correct.

He has a non HP DME converted to HP DME believe. D3 1C is the Non HP internal bar sensor scaling and it needs to be changed to c2 5F scaling for HP tunes.

I know, but he said he couldn't find the D31C but then said it had D31C originally.

I meant what he did was correct.

[Jeppe1976]

Yes, D3 1C is in the DME now - mine DME was a NON HP before..
Does anyone know what the difference would be from D3 1C to C2 F5 if i check the values with a diagnostic tool? And can i toast the DME if i try to change it?
