SL/R129: One Touch Automatic Roof
How is that.
As for the Forum Tax, I think it's ridiculous.

I think overriding the speed sensor is WAY to dangerous!!! PLEASE do not offer this as an option - unless the circuit has an override.
Imagine a falsely triggered circuit when you're travelling at 50+....

I could offer another way to do this...
Get with Micros and go digital!
I have my window dropper coming ready to build soon that some of you will of heard of. (auto drop / raise window for earlier R129s) Small metal & plastic box 2 x 1.25 x 0.5".
My design can take a number of inputs and control outputs to various programs loaded.
This would be a software only change for me I expect for the Dropper circuit, covering everything - speed input for speed detect, switch input latched to hold the switch on, high power FET drive for the outputs.
I make my circuits user-programmable at powerup, so you can set things like timing parameters and in this case say speed at which it wont start.
But holds all parameters with powerdown, only recal at poweron if you want.
(Other circuit I've running in my car is a radar detector (or anything, eg lights) autoshutoff. I power the detector off the visor, where it clips, and use the volts in the visor, but these stay on all the time, danger of flattening your battery (just did it the other day darn, so built the circuit, all going now).
This requires no extra wires, just senses the change in voltage, but does not use an absolute voltage, so temperature or battery condition will not be a problem. All easy to do with a micro in the thing. Tiny circuit about 1 inch by 0.7. )
(Trying to stop paying customers troubling me with work so I can get these all in production)

1. I am creating a general electronic control module that uses a microprocessor, not logic gates, so is easy to make one bit of hardware do a variety of things, with different programs.
2. I have one in use to drop (door open) and re-raise the window (after door close) on my 92 R129. This makes door closing a consistent process, and the door just closes with its own weight, no slamming like when the window is up.
3. I have another in use as a timeout for accessories such as radar detectors or lights. My case - a radar detector powered off the sunvisor.
4. This design could do the one-touch-roof device.
I am getting these designss tidy enough to manufacture for others to buy.
Here is a pic of the prototype enclosure and PCBs.
Took a video of the dropper in action, but not sorted cutting it up into a suitable form to post yet.
Hope this is a bit clearer....

As I stated before, both versions are available. It just depends on the vehicles VIN.
