Got tired of looking for these some have them listed at $75 and 90, but no Who's interested? I know I need one soon!

I’ve done some research into what Paul Anders detailed in the Djet system.
From his notes on the 0 280 130 003 and 0 280 130 012 versions of this part he mentioned
“012 sensor is in short supply. Either sensor should work OK.”
Looks like the curves are actually within 1.5% for the adjustability mixture control. that's on the rich side (of the 003 sensor) or about .5% of the final mixture (as it's about 30%).
I’ve checked the resistance curve on these and found them to be within 5%. As the fuel control is only adjustable by about 30% it would mean that the potential error would be about 1.5% too rich for a very cold start (about freezing) . the curve closes the warmer it gets.
For those that want to know the actual parts breakdown it goes like this –
70-73 - 1.7 sensor is the 0 280 130 003
74—76 – 2.0 sensor is the 0 280 130 012
73 2.0 used 0 280 130 017 but added a ballast resistor to compensate for the difference in the curve it had. Making it very similar to the 0 280 130 012, but will be richer on warm side and leaner when cold.
So the only thing I can possibly see a problem with is the 73 set up with the resistor present. If this applies to you, it’s possible the curve may be off some. If this is noticeable I can’t say for sure until I have feedback.
Just to note – Do not run ballast with my part with the ballast or wit will just be way too rich.
You will note that the attachment wire protection has been beefed up a little more than the OEM. This is because the wire on the stock part was known to break.


I have been told the 73 ECU will work as long as the ballast is not used.
