Everyone told me to download freescan,but it will not work with my 95z.I set it to 94 and some parameters don't work.


Anyone have a suggestion???????


Edit:We have it working.

 

Since I did not see a setting for 1995 in the vehicle selection, I used the 1994 setting and it seems to work fine. What do you find not working?

 

We were just playing around and had to change the area where it says: listen
interact

So we click interact and hit the button that says force data.The software is on my desk top so I couldn't drive anywhere.I have a code 64(right O2 lean).the rest of the numbers I have no idea what they mean.

How can I save it so I can post it here and get some advice???

 

What is this "Freescan " sorry but I'm new here

You can start "CSV logging" to create a file that is viewable with Excel or similar.

If you have not already, read Fred/Injuneer's write-up on pcm data. It will give you some basis for readings.

Farc:
FreeScan is a freeware program that can be used with a special cable and computer to monitor OBD-I data.

So with the code 64(right O2 lean),would that give me .875 for R-o2 volts while the L-o2 volts where .453?I know I've been having crappy gas mileage for the better part of 6 months.Now its starting the low rpm stutter,yet no code thrown for the stutter.The car had been idling for about 10 minutes when we scanned it.Not sure if it even went into closed loop.


I jotted down a few numbers because we tried to save it,but we were unsuccesful.Not sure if any of these numbers have an answer to my poor mileage but I'll put them up.

BTW,I know I need a laptop and log some real time runs.These numbers are at idle after 10 minutes.


iac pos 52
map .458
baro 1.033
o2 volts left .453
o2 volts right .875
Spark Advance 27
Knock count 4221
Integrator left 128
integrator right 128
blm contents 108-------cell16

 

O2 readings are not too meaningful because they jump all over the place except at WOT. You can use the "status bits" tab to tell whether you are in closed loop. BLMs don't mean too much either, unless you are in closed loop.

If you start communications where the status messages are rolling and then start the csv logging, it should work. I have only used it a few times myself and only from a desktop computer, since I don't have a laptop to use right now. If you could get a capture and post the csv file, it would be a lot better for someone to be able to look at.
