Chris, open your file that your going to run the script on. Then go to Edit --->Configure Display Units ---> then select "All", then "Metric", then ok. Now run the script and it should RUN.

But, I just tried this and I couldn't get the changes to apply.. :confused:

Tune pulls hard, but a lot of timing rattle around 2500 RPMs.

I'm trying to work it out but no luck. :confused:
At approximately what throttle position? It's been a while since I've run the tune, but I don't remember ever having any excessive timing rattle on my truck.

edit: It is set to drop to 1 injection pulse at 2400 RPM (no pilot), maybe that's what you're hearing?

Full Throttle I get it, I didn't really try it out at 1/2 or 3/4 throttle; The rattle is pretty loud IMO, like a old Powerstroke.

Can you post a log with RPM, injection quantity, pulse, rail pressure, and timing? The timing really isn't that aggressive in this tune. I'm wondering if there is a multiplier that is raising your timing significantly higher than the desired tables are calling for. I've had problems with some tunes in the past that were adding more timing than I wanted, and I started pasting my timing tables into the max timing tables to fix it. I made this tune before I started doing that though. I'll do that and post the tune.

I'll make a run in the morning with it and see if I can get some logging done. I'm a EFI live dummy, but I can log :D.

Thanks for you help Josh! I'll really like this tune without the rattle.

Whats the approx power you think?

Transmission limp won't limit it to 2k. Was it stuck in a gear?
