Can you post the DataMaster log file (.uni)? I don't think your lazy, maybe need a study partner / mentor?

I just gave it a shot but the site said my attachment was to big. 2,173 KB
I'll be running up to Mom's tomorrow to bring her laundry and do her shopping so I'll get a smaller sample then. Shame you can't get this one as the egr code shows, dtc 32 if I'm right. Damn SES lights when I'm on the road but turns off on restart. Doesn't set a hard code.
Not that I plan to fix this engine but if someone at astrosafari needs it, it would be nice to know what goes on. It has 150K on it and blows a little smoke at first start of the day but other than that it's strong so she would be a good candidate for a quick rebuild.

Thanks for trying to attach the .uni file.
I just attached a 2.8 Meg .uni file, as a .zip file.
Right click the the file you want to zip.
Then scroll down to "Send To"
Then click "Compressed zip" ... Done
See screen shot sample.
The 2.8 Meg file became about .5 Meg which will attach.
I've also attached a screen shot of the Histogram of the attached .uni. Red is NOT GOOD! I think this file was recorded from a custom chip purchased from an ebay seller. (The file is about 5 years old) In all fairness to the custom chip ebay seller, I had the advantage of being with the vehicle. In all fairness to the ebay custom chip seller, the vehicle owner was skeptical of my services so it was a competition who provided the better correction using the same data log. My corrections worked out better than ebay chip seller. The vehicle owner returned his custom chip, and proceeded to use my services.

I played back the log, see attached screen shot. Overall, it's lean. Maybe the EGR is the cause of the lean condition?
If it was my vehicle, I'd either fix the EGR or disable the EGR in the PROM chip. If I decided to disable the EGR, I'd use an adapter board for the replacement PROM chip, see attached picture.
I'm thinking you are going to replace the engine soon, it might be OK to leave the EGR as is?

No, I won't bother to play with it. She runs good as is and passed emissions testing here in CT last summer.
I would like to play with the TunerPro program just to get familiar with it. When I swap to the 350 I'll simply need to use different files for start up, correct? Which program will suit my purposes better or maybe I should ask which program should I spend my time learning? I don't have much spare time to devote to this that is why I ask.
