I've only just painted the white parts this week. Black looked boring inside 😂

Yes it is the CDI 2009

I have seen this other website Evilution, I am a paid for member there and I have been talking to Kane, the owner of the website about this paddle shift. Whichever system you try to use you are faced with great expense and some of the conversions also require programming at a cost of around £100. Then you have the added problem of finding a steering wheel which has the gear change paddle switches already fitted, I have been watching eBay and other websites for quite a few weeks and I've not found a suitable steering wheel. The conversion I have done does not require programming, It is done by using 433MHz remote control, the receiver and logic are mounted next to the SE Drive PCB and no wires need to be run up to the steering wheel. I designed a simple interface that prevents the gear change system from sending more than one signal back into the car, I wasn't sure how the car would react to receiving more than one signal. This interface simply copies the gear + and Gear - signals. The total cost so far is less than £25 for a working system. An earlier post here showed part of the SE Drive circuit, this wouldn't have been done by Mercedes, the schematic looks like it has been done using Eagle, a PCB design software, someone has reverse engineered the SE Drive circuit board. Whilst my system works, having the schematic would be useful to see if the idea can be simplified.

I am working on a conversion system for changing gears that does not require any programming of the SAM or any other unit in the car. I have used Jaguar XF gear paddle switches which are easy to mount. The gear up and down is transmitted using a small radio module and the receiver will connect to the original SE Drive PCB. I have designed a small logic board that connects between the receiver and the SE Drive PCB which switches and routes the signals correctly when changing gears, the logic fools the SE Drive into thinking you are changing gears on the gear lever and not on the steering wheel. I am after the full circuit so I can see if there is an easier way to interface the receiver and the logic interface board.
