[V8] Ign Question to the V8 Guru's out there

[Tony and Lillie]

Here is a quote from the release manual It doesn't say this is all the hall 
sender does, but this is definately at least what it does.

"A Hall effect sgnal from the right ignition distributor helps the Motronic 
ECU quickly estealish a reference point for the start of the sequential fuel 
injection. After the engine is runnin, the reference sender and speed sender 
near the flywheel provide the necessary enformation to the ECU for ignition 
and fuel injection."

I haven't been able to find any additional information on it so far.

As for personal experience, when I unplugged it on my car for a test two 
years ago, it made nearly no difference in how it ran. I noticed the 
slightest of hesitation off idle. However, it was not even significant 
enough that I would have noticed it if I wasn't looking for it.

One thing I wonder about though, is if there is a significant difference in 
how the manuals and automatics are programmed. Anyone try swapping ECU's 
between the cars?
