ECU Tuning Options (Siemens ME2.8)
My C43 has the Siemens ME2.8 ECU in it. I'm wondering what tuning programs can tune this ECU. I know Star Diagnosis can (C3 and C4), but I don't want to pay out the wazoo for it.
So my questions:
So my questions:
- Are there any free or really cheap programs that can get the job done (ECU tune)?
- Does each program require its own multiplexer (reader)? I noticed Carsoft has its own multiplexer and software...not sure if you can use a different reader and get the same results.

Hi, very cool project and congrats for succeeding! Your car looks very, very awesome!
I want do the same you did: C36 engine + tranny into my 124 E320. Now I am really inspired by your work using all the W202-OEM-parts like modules & wiring. My thougths are the same: seperate all the unnecessary stuff from w202's wiring harness.
But my donor C36 has ASR traction control. Here are my major doubts:
-ASR traction control system very similar to normal ABS, differences: wheel speed sensors for both rear wheels instead of single sensor mounted in diff housing - no problem, swap to w202 ASR rear wheel knuckles, they should perfectly fit into w124 axle.
-ASR/ABS pump uses 6 brake lines - no problem, add a second rear brake line
-ASR system uses both front wheel sensors or all wheel sensors for vehicle speed data - Problem when using w202 front abs sensors on w124 wheel knuckle. Does they fit? How did you solve it?
-w202 Tachometer/instrument cluster is different - did you get all important wires from the w202-wiring into the w124 instrument cluster?
Rest should be easy work, it's not my first m104 swap but the first using other platform's wiring and modules.
I hope to hear from you.

Engine mounts and arms get it from w124 E320, direct fit, i forgot to mention one thing, use your AC compressor from w124, dont use the w202, it has different activation module and wiring system. If you use the w202 you will end up installing the wiring from w202 ac which is comolete different system.
In order to do this, you have to get ac compressor bracket from the W124 E320, dont use the w202 bracket.

I forgot the mention one thing, cruise control, you can use the cruise control system from the 202, it is so simple, it is directly controlled by the ECU, ECU connects directly to the switch on the steering column, you can use the w124 switch, just remove the plug and just install the w202 plug, and connects directly to the ECU. Both switch has same wire colors so just follow the order on the w202 switch accordingly. You can remove all the unnecessary cruise control wiring and module from the w124 if you wish.
