Porsche 944 turbo
Update: Got VEMS box nro 731. Old motronic box gave 35 pin connector.
Ordered it with flyback. Do i still have to arrenge flyback for injectors? or are thety built inside the box?
Is it nesessery to groun CLT and IAT sensors all the way to VEMS box or cab they be grounded straight to head or block as CLT is done originally?
Trigger: Polarity? does anybody know polarity of sensors according to DME connector pins?
Chancing crank home sensor polarity: On Audi trigger arrangement the polarity of crank home sensor should be reversed, same with porsche trigger (132 tooth+crank home)?
Fuel pump: Originally Porsche fuel pump has its own relay, and i think motronic cuts its gounding. Must the fuel pump be driven by VEMS?
Original sensors: CLT, TPS can be used (reading wiki helps).
