Need Help Diagnosing Car from DataMaster Files

Just starting to try to see what's wrong with my Z28.

Here are four datamaster files
(2 sitting at an idle and 2 on the road).

If anyone could take a look and let me know anything they see that looks irregular it would be greatly appreciated...

Brief history on car:
1994 Z28, 355 /w hotcam kit, edelbrock headers, tuned computer(so I was told)
Car has very ruff idle, runs very rich, and has a pretty nasty stumble.

I've only had the car two weeks and I hate to just start throwing parts at it.

Here are the links to my datamaster files. Right click and save as...

run1 (http://www.user-friendlysolutions.com/images/run1.uni)
run2 (http://www.user-friendlysolutions.com/images/run2.uni)

Here are the files in csv format...

Right off the top, your injectors are maxed out when you really get on the gas... above 100% duty cycle.

But, you should give a description of the problems your having. That way we have an idea what to look for in the log.

Also, please export Road speed as well in your log, just so we can see that your actually moving... (there may be other ways, but i find road speed is the easiest for me:))

You also get knock just about every time your on the gas, and based on your BLM's your running very lean.

Injectors are something you should look into for sure...

But hopfully someone else can chime in as well, as i'm just reguritating what i've read on here and comparing it to your log...

Cool Thanks for the help. I'll change up the log file ASAP.

Changed the log to include speed.
Problems I'm having are very ruff idle, runs very rich (or at least smells like it), and has a pretty nasty stumble from 0-3000RPMs.

Hey Paul, did you send the files to Madwolf?? (Ion Soltan is his name, I believe), not sure what his email addy is. He's the one who was supposed to have done the tuning, maybe he can lend a helping hand. Later.
