ECU connector pin 34 200 1992

Yes, I found evidence of that on one contact in the ECU connector and one in the EZK. The one on the ECU looks slightly bent, the one on the EZK is missing one of the four springs.

However, they were the knock enrichment signal from EZK to ECU, which measured fine, it did get from EZK to the ECU and the one on the ECU connector I forget, but was somewhere in the middle. Definitely not pin 34.

I measured VSS to be sure, but already knew it had to be present as coasting in the "high idle condition" would lead to a drop from 1000 to 950 rpm shortly (a second or so) after coming to a standstill.

I read on Turbobricks the following (https://forums.tbforums.com/showpost.php?p=2852595&postcount=23):
"If the engine speed (RPM) is above 2100 rpm, the load signal is in the part-load range and the control module does not receive a signal from the speedometer for 8 seconds a diagnostic trouble code (DTC) is stored."

A missing VSS seems to be associated to much higher idle revs than 950, more like 1700 rpm or so. I have yet to see a 3-1-1.

I am wondering: why 200 extra rpm? It's always that number...
