When you set the instrument cluster to ROW it won't turn on the check engine light for anything because check engine lights and only on the north American market cars. The code will still exist but the light will not turn on

 

That would make looking at the dash less annoying but if the code is still in the system it won't pass inspection when they hook up to the data port.

I'm sure something can be coded out in the vehicle's brain. Happy hunting!

 

I just have to find the guy who can code it, anyone know anyone?

You can try contacting Oliver at Speed Tuning USA. He's a very knowledgeable ECU guy and has worked a lot with older MB modules. I had him clone an ECU for me, which involved physically removing the immobilizer chip to copy it. I'm not quite sure if he can help with your particular situation, but it doesn't hurt to ask.

 

Drove it today, terrifying!

So I never did figure out how to turn the check engine light off. Apparently there is a speed sensor in the auto gearbox that the computer is looking for and can't find, so it trips the Check Engine light. Mercedes was no help because there isn't a space in the computer to switch to this gearbox. They said find someone to rewrite the code in the computer. I found a company in FL who can do it but they needed the car, not just the computer. So I would have to ship them the car, with a blank check, not very appealing.
That's the bad news, the good news is in 2 years the car ages out for emissions testing in NY, so I will just drive with my dealer plates for the next two years then start registering it again once it doesn't fail the yearly NY inspection. It is a blast to drive, so no regrets, just more complicated then I initially imagined.

 

I would suggest you get in contact with raw 1879 as he has a manual conversion and drives the Nurburgring frequently. I think this question was discussed in one of his threads

 

Do you have the auto gear shift connected and in neutral? I've seen some write-ups and YouTube videos that mention that.

I've been thinking of doing the project as well. Was hoping I could disassemble much the shifter to lessen the size and stuff the remaining needed electronic bits under the dash or console.

 

I have the same exact issue on my 1997 C36 with a 6 speed swap- 97 first year of 722.6. There are CEL's all related to the missing automatic. The stock TCU is plugged in and set to neutral.

From what I gather, you need a STAR or HHT with developer mode to code the ecu and tell it the car has a manual. I recently tried a shop in NJ who was willing to give it a go, but his machines would not communicate with the ecu. Anyone in the Philly, NYC, New England area able to do this work. The NJ shop said the work is not difficult if you can get into the ecu.

I talked to Oliver from Speedtuning and need to open up the ecu and send him a picture of the guts. I have used him in the past for W124 3.6 swaps.

 

So I sent my ECU out to Josh at Mercedes Swap Shop in CA hoping I can eliminate the CEL's and have it coded for a manual trans. I will post up if it gets sorted out.

Interesting. Do you think he could get all the electronics talking together the same language in case of a M113K transplant? Many have tried but very few have succeeded and those who have keep the know-how and their cards hidden.

 

I am not really sure, but you should reach out to him and ask. My ECU will be back on Monday so crossing my fingers all is fixed.

 

As far as I know it depends on the year. Only a 2000+ can have the CEL coded out. Anything before that will require the original transmission shift selector still plugged in but left in Neutral.

 

Has anyone here used Mercedes Swap Shop for ECU tuning?

Looks like they can do some interesting stuff with coding tests out of the ECU.

 

It appears that my issues have been resolved. I installed the ECU today and took the car out for a good run.

Josh said that I should be able to unplug the old TCU now that the coding is done. I will try that later in the week.

I forwarded him this thread. He said that he can do the M113K coding that was asked about.

 

Any update? How did you wire in the clutch switch to make sure it won't start unless clutch is depressed?

 

Is it bad that I'm more interested what's going on with all of those ghostly looking air cooled 911s?

 

Car is running great. It is as if the car came from the factory as a manual equipped car. I am not positive on the clutch switch question, but can test it out.

 

I reached out to Jost at Mercedes Swap Shop and he told me -

"It is worth noting that you will probably have an ESP light with no traction control or ABS. I’m still trying to figure out which ESP module needs to be in there for it to work right. Cruise will only work if you wire in the Clutch Pedal Position Switch"

So curious if you did anything extra. Does your Cruise Control, ESP and ABS work?

 

My C36 is a 1997 so there it is not equipped with ESP. The car does have ASR and believe it is disabled now. I am not positive about ABS, but the braking seems normal. Not sure on cruise control as I have never tried using it in any of my cars.
