OK, my first thought was that the original wiring (single white wire- to distributor) had something to do with a safety feature, but obviously not:
the white wire which provides switching power to the main relay at pin 86 is hot whenever the key is on.
Good to know! Thankś Don.
White wire is connected to + on coil (pin 15) and everything is working well except for one thing. I had hoped that the 123 ignition would give the engine more boost from idle -- better acceleration, but it is like it was with the old distributor. The engine has only been running a fem kilometers but I had expected more power and instant reaction from idle an upwards. Itś very different from other cars. Is there any adjustments that can be done that might solve this?
Now that your engine is running, confirm that your actual timing matches your 123 curve by checking with a timing light.
The 123 timing seems to be almost spot on according to my timing light, so this should not be the reason for the slow reaction when running in a low rev. I know that the potentiometer at the ECU is turned to minimum CO%. Can this be an issue?
