This ECU worked as a charm! Now running K-jet for fuel and Vems for ignition.
Using the Primary Vr non-reversed (yellow as signal) and reversed the secondary VR inside the ecu (black as signal) both wires are avaliable in the stock 25pin-connector.
Using a Stepper output for ignition output.
This is the car for those who´re intrested, as you see he has several more that wants the same threatment.
Need some help on building an plugnplay-ecu for an old 10v urquattro running a 25pin toshiba ecu.
Its running the standard three sensor Auditrigger.
Ive connected the Primary VR sensor to EC36/27.
Should I connect the Hallsensor to EC36/13?
Where on the board should i connect the Secondary VR sensor?
Board Serialnr 3919 . Ordered with Auditrigger setup.
Thanks for all your help!
Ive come this far:
Connect the sec VR trigger like this black and red wires
You may need a 1.5 kohm resister mounted on solder side at ends of wires. (Pull down)
Thanks Peter! That helps alot! I ordered the board with 1kohm pulldown for the secondary vr. So thats done.
Are there any jumpers needed for the Hallsensor to find its way ? Or is it enough to connect it to ec36/13?
