So after putting my log file up here and having a look back over the details im wondering what the following mean / reflect :

 

A/F Base? What should this figure be as it didnt seem to change much with throttle position or speed etc really, always seemed to be around 100 +- 2

 

Injector? Its not the duty cycle as that is listed separatly ?

And Airflow? Guessing this is the output of the MAF so should go up with the throttle reading etc...

 

Just after a list of normal values as a starting place really...

Also, noticed that during the run my PowerSteer (green thingy at the bottom ) remained off ? This showing anything wrong or just that the road i was on was pretty straight?

I hope you get the info, i could do with it as well. Did the same as you today 0-60 and recorded a log file, it would be good to find out the basics from someone and my powersteer stayed of as well, though it wasnt a straight road.

its perhapse just the way datascan reads the powersteering input? Im pretty happy my PS is working ok and it might just be a logging issue. I also noticed that during the replay of my data the mixture was showing as rich throughout, even though during the run (and if you open the log file) it was normal (switching between rich/lean)

A/F base = Air fuel ratio (mixture) The ecu uses both O2 readings and will try to keep this a close to a perfect mixture as possible (110 on the display). The numbers arnt very usefull as you need to actually know how lean or how rich the values represent (may use a wideband one day to work them out). You will notice on cold start up that the number is higher (richer) because of the Cold start injector.

 

I *think* that the Injection Value is for the Injector Pulse width, The longer the pulse width, the more fuel is injected.

 

Airflow is the Voltage generated by the Airflow meter, bigger volatage = more air being drawn in.

 

Unfortunately with this software, there is no discriptions or defs for any of the values produced by it :-(
