Default Re: Comprehensive SMG to 6MT Conversion Thread

>Pin 2: Bl/Br (Blue w/Brown Stripe) -> Pin 1 gear switch -> Pin 2 Gear Switch -> Pin 20 Gr/Bl @ DME x60002.

Assuming Pin 1 Gear Switch is the brown/black wire coming to Pin 13 on SMG ECU.
Now how do I identify Pin 2 Gear Switch wire?
Meaning what do I connect to Pin 20 on DME?

Thanks,
George K.

Answering my own question here))
The other wire that goes to pin 20 on DME is from pin 31 on SMG ECU if you are reusing transmission fluid temp sensor wire that is.

For those looking to do this in NorCal, this might be of value (CL link will expire at some point, but...) https://sfbay.craigslist.org/eby/pts...380306318.html

Machines bellhousings for diy-er doing conversion on their own or full conversions are offered. Price listed on CL is $550 (assuming for the former).

In case it expires, phone number listed: ☎ (925) 961-6429 and CL email sgsn5-6380306318@sale.craigslist.org

You don’t need the Gear Postion Sensor (GPS) wired, everything still work as it is, cruise control etc

Clutch Pedal Switch Wiring Without GPS Sensor:

In order to make the cruise control work, without the Gear Position Sensor (GPS), You’ll need to make sure you have genuine e46 m3 Clutch Pedal Switch (goes on the clutch pedal inside the car) you cannot use any other e46 one, although they look the same physically, cruise control won’t work if you don’t have the proper e46 m3 one.

A total of three wires need to be wired to the Clutch Pedal Switch:

Pin 1 Br/Sw (Brown w/Black stripe): Ground (tap into the brake light switch on pedal box that has the same wiring colours

Pin 2 Wire To X60002/Pin 20 To in the engine bay fuse box, I ran it through a grommet under the fuse box behind the glove box.



Pin 3 Vi/Ge (Violet w/Yellow Stripe): 12V (tap into the brake light switch on pedal box which has the same wire colours).

In USA you can have press the clutch to start, but I don’t see why you need that feature, we don’t have that in the UK.

If you do want that added then

Pin 4: Bl/Sw (Blue w/Black Stripe): Pin 8 in EWS (white box in upper lefthand side of driver's footwell. Pin 8 is empty). If you remove the two 10mm plastic nuts that hold the EWS module in the footwell, you will be able to see the pin numbering scheme to be sure you make the correct connection. Pin 8 is in the upper right hand corner of the small pins. Again, in order to insert the female pin into position 8 in the EWS connector, you will have to disconnect and then disassemble the connector itself.

You’ll have to enable the Press Clutch To Start function via NCSExpert


Coding For If No GPS Sensor Is Fitted:


You need to be competent in using NCSExpert. If not I'd advise paying a professional as you may risk damaging module(s), it has been discussed in main SMG To Manual Conversion Thread, regarding what I done to code.

http://m3forum.net/m3forum/showthread.php?t=444126

For example changing Vehicle Order (VO), and adding/removing options from Modules. NCS Dummy helps understand what the options mean in English.

1) Using NCSExpert, Remove $793 (this is the SMG option by the way) from the Vehicle Order in AKMB and ALSZ modules then write the new Vehicle Order back to the AKMB and ALSZ modules.

2) Modules to Code With NCSExpert, note in brackets is the NCSExpert name for the modules)
- DSC (DSC), change from SMG to Manual
- Instrument Cluster (AKMB) removing any SMG options, then adding any manual options that are available to select
- Immobiliser (AEWS) - remove press Brake Pedal To Start - US cars if you wired the clutch switch properly, you may need to add this option In, press clutch to start
-
NOTE: As stated above, NCSDummy makes doing the changes above much easier

3) Flash the DME with the 6MT software** (or alternatively, read the ECU data with something like BMWFlash, change the byte at offset 8 from 40 to 03 in both sections, and flash back to the car). There are two ways to change the ECU to the manual changes using Martyn's tool (just select MANUAL in transmission) or WinKFP.

It depends if you haven't installed the Gear Position Sensor (GPS) on the transmission then to make cruise control work, you need to wire Clutch switch Pin 2 -> X60002/Pin 20

Make sure you use a E46 M3 clutch switch, I've tried other e46 clutch switches (they look identical) but cruise control will not work otherwise.

You'll need to make the following changes to your ECU. Special thanks to Terra for the help and Martyn's DME binary tool.

For cruise control to work, without the GPS installed.

I used Hex Edit for Windows, it's free and really simple to use. You cannot do this part in Martyn's tool at the moment.

Note some USA cars have the clutch bounce issue, I've never had issue with my clutch (maybe USA ones are setup differently)

1.

This part deletes the Gear Postion Sensor from the DME

Current value will be: 01,
You need to change it to 02 in 4028

Type 4028 the hex address in the box highlighted at the top and hit return, the cursor will then be taken to that byte, you need to change to 02



2.

This bit stops the a error

Change to FFFF in 0x35AC

Type in 0x35AC in the Hex Edit software like I did then change to FFFF see the difference between the two images for the change.

You should be changing the next word (0032 -> FFFF)

Also it's worth noting that the address will vary from software version to software version. So just search for "003232FF00F7" and change that first "0032" to "FFFF"

Before



After



4) Flash the .bin file back to the car with something like BMWFLASH

5) Clear all DME adaptions with INPA

6) Start the car.
