Tune Analysis 5.0 A9L

Unread post by Justin Jones »

I loaded the tune you sent me and ran a small log but it was probably too small or not in closed loop yet (because it was surging a lot) to do any good. I see that in your directions now, after the fact. It's Datalog 1 Idle.

Also, when I try to close TunerPro, it says "Aquisition Definition Modified, Save?" Do I save that?

And that datalog is attached now to TunerPro instead of just being a saved datalog which I thought it would be. Is this correct?

I think the tune is corrupted as the fuel pump ran a little longer than I expected. I just shut the key off and then restarted.

why did you start a new thread?

the log file is just idle that's useless

it was surging cuz your throttle stop isn't set correctly. You need to open it at least half a turn.

If your going to post a log to evaluate your tune you might as well do wot and all in there.

I started a new thread because it wasn't about the Datalogging Patch anymore.

I realize an idle datalog is useless. I'm reading your directions on the homepage but also trying to follow your directions that are listed under the steps. i.e. Step 1 says it's only for those directed there by you with a custom tune. I just didn't think I fit into that category. I will purchase the Custom Tuning package if I need to.

The surging started to smooth out the longer it ran.
