I love to see the smg guys talk about how fast the smg is next to the 6sp. How's this anyone near or from NY with a smg that wants to test that fact? I have a stock car except for the exhaust so you take off all your crap and we'll race deal ?

I believe it's driver not smg vs stick.:eek
Anyone who wants to play pm me. I'll set it all up, and I will make sure it's all on video.
As a person who even has a Lamborghini Gallardo in manual which is extremely rare, I have to disagree with you. You couldn't shift as fast as an SMG if your life depended on it.

I have begun ordering parts to finally go through with this on my 2007. This is my personal list I have compiled based on new parts, just to get an idea of all the parts related to option 2MA. Don't let the prices listed turn you off to this project; this is a worst case scenario cost situation above. I found a LOT of the stuff used and will only be using new parts where it matters. My final cost for parts alone is just under $2,800 including the trans, new flywheel, clutch kit, pedal assy, and driveshaft.

In addition to parts, the DME will need flashed to the manual software and there are 4 pinning changes that need to be made for the reverse switch, neutral position sensor, yaw rate sensor, and the fluid sensors on the 6MT. Pins need to be moved from the SMG ECU to the DME as the SMG ECU will no longer be there. I'll post details as I get into the conversion after the holiday.

NICE! Definitely want details as you proceed

Isn't it next to impossible to find a used 6 speed trans ?
Not at all

I personally have access to 30+ of them so the transmission is not the issue.


We begin the madness with the first major electrical change that needs to happen - adding in the clutch switch. The 6MT cars have a clutch switch/position sensor on the side of the clutch master cylinder on the clutch pedal. If you buy a used clutch pedal assembly, it will probably already be on it, and your job will be a little easier. Here it is:

Along with the clutch switch, you will need a 4 pin connector like this:

Image


Image


You then need to run 4 wires after adding the clutch switch, and pinning them into your connector above. Here are the 4 clutch switch wires:

Image


Pin/wire in cavity #1 on the clutch switch needs to be run to chassis ground somewhere. Either tap into a ground comb somewhere close by or terminate a ring terminal onto the wire and ground it manually somewhere. Make sure you verify low continuity to ground over the wire to verify a good connection to ground or the switch won't work and you will have errors.

Pin/wire in cavity #2 on the clutch switch needs to be run to the DME engine ECU in the engine bay. It needs to go into cavity #18 on connector x60001:

Image


Pin/wire in cavity #3 on the clutch switch needs to be run to the CAS module cavity #3, connector X10318.

Pin/wire in cavity #4 on the clutch switch needs to be run to the CAS module cavity #41, connector X10318.

All of these pins SHOULD be missing in the CAS and DME. If they are already populated, we need to follow them and see if the car is possibly already pre wired which would be a total shocker BUT you never know.

Stay tuned!!

Yaw rate sensor, neutral sensor, fluid temp sensor, and reverse switch are next.
 
That looks identical to the clutch signal that is added during the E46 M3 smg -> manual swap.

I'm curious to see what would happen if you just recode the DME with the manual version (winkfp etc). On the E46 cars, you don't really have to run all the extra wiring to get the car running.
 
The next task is adding in the neutral sensor on top of the trans:

Image


As with the clutch switch, this part does not exist in an SMG car from what I can see. HOPEFULLY whoever you buy your transmission from leaves this on to save you some money.

3 wires need to be run from this sensor directly to the DME engine ECU:

Image


Here's the connector for the neutral sensor:

Image


Image


The pin/wire from cavity 1 goes to the DME connector X60002 from my previous post above, into cavity 6 in said connector.

The pin/wire from cavity 2 goes to the DME connector X60002 from my previous post above, into cavity 9 on the DME, and pin 3 on the neutral sensor goes to cavity 19 on the DME.

To simplify things with the transmission connectors you can use this harness:

Image


BUT, if you go this route you still need to handle the female side of the big connector and its wires to the DME

Image
 
The output shaft speed sensor exists in both SMG and 6MT cars, but pinning is slightly different

SMG:

Image


6MT

Image


Schematics above indicate that we need to remove the output shaft speed sensor signal wire from cavity 11 on the SMG ECU connector X70014, and move it to the DME connector x60002 into cavity 22.

Image



Image


The wire on pin #2 from the output shaft speed sensor needs to be spliced into the wire going into pin #1 on the neutral sensor pictured above in my earlier posts. This is the signal ground wire (Referred to as M_{masse}PKS in the scematics) for the transmission sensors.
 
Another major change is the yaw rate sensor...

In SMG cars it is wired directly to the SMG ECU, in 6MT cars it is wired directly to the DME. It's located under the front passenger seat:

Image


SMG:

Image


Pins 13 (yaw pin 3), 18 (yaw pin 1), and 20 (yaw pin 2) need removed from the SMG connector X53003.

6MT

Image


Yaw pin 3 needs to go to cavity 11 on x60001 on DME

Yaw pin 1 needs to go to cavity 9 on x60001 on DME

Yaw pin 2 needs to go to cavity 10 on x60001 on DME
 
Lastly, the trans temp sensor, and reverse sensor.

Temp sensor:

Image


Located on the bottom driver side of the transmission. Pin 2 needs run to DME pin 9 on the x60005 connector. Pin 1 wire needs run and spliced into the m_PKS wire on the neutral sensor.

Image


Image





Reverse switch:

Image


Located on passenger rear bottom area of transmission.

Image


Pin 2 on reverse switch needs run to pin 13 on the light module connector:

Image


Image


Pin 1 wire needs run to chassis ground somehwere
