what are healthy datalog #'s?

Are there basic #'s to look for in a healthy LT1 datalog?

I'm hoping for a summary of ranges the #'s should fall under.

thanks

I have a 20÷ page writeup covering the interpretation of LT1 scan data. My website is down right now but I can send you a .pdf of it if you want.

Re: what are healthy datalog #'s?

I have a specific question in regards to Datamaster. Does the speed readout take the measurement from the PCM? for example if it says I driving at 60 kph is that what the PCM is reading or the speedo?

I've changed my rear end ratio to 3.73 and had the PCM recalibrated but want to see how accurate it is.

There is a .pdf download available in this post on another site (post #44 in the thread):

Gonna try my hand at writing an OBD1 scanner app - Firebird Nation - Page 3

Even though I'm an Admin there, I don't know if it will let you download the file if you are not a member of the site.
