There is a commercial product available now for the W126 that does this, available at Mercedes-benz V8 V12 w126 SE SEC SEL,R129,R107 SL,w124 500E,400E,w116,w140 SEL CL First gear start module tuning transmission

Anyone know this First Gear Start module...?

Welcome to Berg Werks!

$250 is a bit more than I was going to charge for the device I came up with and that device does a bit more than mine is going to.
My original intent with this was to build it for Hit Man X in exchange for some parts.
I suppose I could come up with an interface for setting the shift speed as well. That's not that difficult at all considering the controller has a USB interface. At that a 0-60 time device would be easy too but largely not useful for core functionality.
As 97 SL320 mentioned my biggest issues so far are:
1) investigating solenoid life and duty cycle.etc.
2) filtering, attenuating speedometer input signal for the controller.
Function List
-First Gear Downshift/Up-shift at Preset/User Determined Speed
-Disable Switch to resume second gear starting
