 |
|
So I was looking at my stock of spare Idle Stabilizer Control Modules a few minutes ago and become curious about the part numbers being the same, but having a different suffix letter at the end of the part number.
One version has a "B" and another a "D"
What's the difference and can either one be used with ECU #025 906 022 D.
I'm making the basic assumption the"B" was for earlier years and the "D" the later years, but which years were they changed?

Steve, you probably already know this, but I wonder if Zoti would know the answer since he is working on new module project?

I skimmed trough the "Alternate Idle Stabilizer" thread, but did not see any reference to the version. Nobody asked the question there for it to be answered

They are different but perform the same function. The D version is more "modern". Both are just sort of an analogue computer.
Our new version is going to be a digital computer and will be able to adjust everything by code. There's nothing you can adjust on those original ICUs. |

We were going over it ourselves while trying to understand how it works. Their schematics are different but they basically do the same thing. D is latest version. Both will work with your ECU. They don't really communicate with the ECU. Just share a few of the same inputs.
The ISCU is a standalone unit. |
