My question is about the format Actron uses to display degrees of knock retard. In the 'Knock Retard' field I am seeing 5-7 at idle, and have seen up to 70 while driving. Brand new build, less than 5 miles of break-in so far.

Obviously 70 degrees of spark retard is not real, so I'm assuming it means 7.0 degrees but does not show the decimal point. If this is consistant, the idle retard display of 5 to 7 would mean 0.5 to 0.7 degrees.

Can anybody tell me if this is right?

I have read the Actron FAQ, instructions, etc and INjuneers guide, but can't find this detail explained. Thanks.

 

Doesn't anybody use one of these?

 

Follow up answer in case somebody else needs to know:

I compared with freescan, and the Actron shows actual knock retard x 10, even for single digit readings. In other words, when it shows 7, that's 0.7, and if it shows 12, that's 1.2 degrees retard. FYI.

 

I think you mean x .10 - not x 10.

 

Which model are you referring to? I have the CP9145 with live data. I'll have to look at again as I don't remember seeing what you are writing about.
