Hello!
Ive been installing a link g4 pnp ecu into my 1995 R33 gtst.
It all went smooth untill yesterday when i got to section 6.8.2B and set the injection mode to ”off”.
And then proceeded to cycle the power (ignition off and on).
The ecu woudlnt connect to my pc.
Checked pins 49-50 and 59-60and i was not getting power to my ECU.
I investigated the pin 45 power Feed from the igintion and it was ok.
But i was only getting 11,4 volt on the pin16 (A2 on the eccs relay). Same voltage on relay pin2 (power to ECU pin 49,59,109)
I Looked around the forums for a bit for solutions.
I came up with that the circuit for pulling the relay (aka pin 45 and 16) would be broken inside the ecu.
I Made a jumper between relay A2 and chassie ground. And now it all works.
But if i remove pin 16 från the relay (meaning also chassie ground) it stops working and instead of a steady green light (on the ecu pcb) i get a flashing light.
Ive measured between the relays + to pin 50&60 to make sure i got ground and thats fine.
