Hello..


I loged a 50min ride with datamaster. I got 2knocks , all when I accelerate quick. BUT I got 9 times where I got spark retard,on diffrent locations. All around 2800 rpm/60-70 kpa and around 0.2-3 degrees. How can this happend, I thougt only the knock censor triggerd spark retarad??

thanks

 

The knock counts output to the ALDL is only the MSB of the counter. Can get knock counts that aren't shown via the ALDL link.

ok, makes sense...

thanks rbob

 

Just patch the code so that instead of the msb, have it spit out lsb! It's a better indicator even with slower 160 baud.

 

hmm how do I do that?

 

Get the hac for your bin.
Look for the aldl list. There are several.
But only one real long one.
That will give you the address for that word (MSB).
And list the address that the is sent in the aldl stream.
Change the address to the LSB using the hex editor.
Normally its just one # higher. So you only need to change one
digit.
Here is the 58 example.
The first alpha numeric is the address on the chip.
You have to subtract your load offset to get the address in the bin for use with the hex editor.
If this is not clear, it's probably my fault. I'm a terrible teacher.
Never mind the language thing. You write fine.

edit: oops
Apparently, your code only sends the MSB.
So using the above ex, you'd change it to $00AA instead.

 

thanks
