You sent me a custom tune a long long time ago. Would happen to still have it. I can't find the file anymore.

21 years later, i'm still running the same tune in my 05 Avalanche. My computer that had the old log tool. No longer functions. Is there any way to get the software and log my tune to make adjustments.

I have been away from the forum for quite a while. My Predator is Release V.9r07. What are the changes in Release 9r11? Should I update my tool? I have been running the same tune for about 1 1/2 years without any changes.

checked out your log...

I would go another -2%...

you are saving the change after you adjust the slider, right? adjust it, press the center button to save it, then install the tune with the saved change???

cuz the ltft's are similar to your first log I had checked out... doesn't seem like your ...

I am in Austin.

Here is my latest log. I adjusted -2 from my last log and now this one says to adjust another -3. Does this seem right?

I did another log with the right parameters set. Have not adjusted injector slope yet.

Thanks!! Those were the answers I was looking for! Now I just need to modify the tune.

ok, looked at your log....

your average ltft's are at 2.7xx and 3.6xx... so for now, I'd say to go -3% on your injector slope setting... install that modified/adjusted tune setting, put on about 75 miles, and then do a new steady driving/cruising log... and select the appropriate throttle ...

I am sure it has already been explained, but was exactly does adjusting the injector slope do for performance?

I uploaded the wrong file before. The coreect one is above.

I did get the log from data viewer. It opened in Excel just fine for me. I will export it again later today and email it to you. It will be a few days before I can get a new log.

Thanks

After doing some more Reading in this forum it looks like I need to get a fresh log since I had the AC on. It was only 104 outside. Looks like some night logging. Just need to figure out what I can log and should log????

Well I did my first log. Unfortunately DSLOGREDUX could not complete the analysis. It says I need to also log one of the following, command throttle position, absolute throttle position, or the Accelerator pedal position. I thought that the U7193 did not log these so I did not look for them when I ...

I did a run with the fast data log today. It took about 20-25 minutes to do the log. Now I just need to get my USB-Serla cable next week to see the results.
