INcase it goes down or deleted:

I will assume that all those reading will have base MS knowledge. Those who don't feel free to ask some questions.

1992 SLC engine/drivetrain into a 1992 GTI (my old one). Car has been running a stock chipped ECU for a little over a year. All factory sensors have been used, only addition to the engine bay is a single vacuum line for the map signal.

Wiring is straight forward from a cut up Motronic ECU connector to the MS DB37 connector. I will post the pinout below.

[MS to Motronic Pinout Placeholder]

Board built and tuned by me.

MS1 V3
MSnS-E 029t

Board mods/hardware:

VRIN - TSEL
TSEL - VROUT INV
D14 with pullup to IGN (no VB)

Tach Circuit (not working yet) w/ 2k pullup

TIP120 for PWM idle valve with 1N4001 flyback diode between output and 12v

Remove Q4, Q20 and R39. replace R39 with a wired link or solder the (E) emittor to the right side of position R39 rather than at the Q4 position.
