Idle Tips & Tricks

[WeathermanShawn]

Yea, it is kinda of a generic statement. There are so many Airflow parameters under 'Trim', Start-Up', etc..I have seen a few Tunes that had dozens of Tables altered..so my general premise is to load a Tune then run an 'Alternate Calibration' of a stock tune.

Here was an example of about the most changes you should see on a LS1 cam/Idle Tune (see attachment). Thats about the maximum airflow parameters described in my Idle Tutorial and SSpdDmon's Idle Tutorial. Any more changes than that may be a case of diminishing returns. I'll add it to the Tutorial if I can think of a simple way of saying it...

Hope that helps.

ok, dont know why this one is kicking my butt, but I cant get it to copy/paste. I loaded the b4307 desired airflow IG/AC OFF imperial map, changed data to airflow rate from maf g/sec. And when I try to copy/paste it says it cant find any matching row/column data will not be pasted. I then changed the units in b4307 in tune tool to metric and loaded the metric map and it does the same thing. I will attach log and tune. What am I missing for units??

In tunetool, goto B4307, click in upperleft corner of table (where x and y axis intersect), and copy-with-labels.

Then in scantool, goto map, for each of Row and Col do Paste Labels and save map;

make sure units in map data/row/col match those in B4307.

now try again.

Joecar,
I tried that before, and again just now. If I copy at the axis it puts park/neutral in the map too. Then it will copy/paste, but only in the park/neutral column. If I just copy the IG it wont do copy paste. Do I need to log desired IAC airflow?? I tried that on my first log and it did the same thing. I assumed that using the maf g/sec data I wouldnt need IAC airflow

Len, can you just open your Tune Tool and manually type in those values?

Probably fastest that way. I just did it here on my end with no problem (typed in)..

Edit: I then blended in the colder ECT's..

P.S. I had the same problem you did with cut and paste..

[rpmauto]

yea, I dont know what the problem with the cut/paste is. I can just enter the data in. It is just kinda aggravating not knowing why I couldnt get it to work. Might have to try it on another car and see what happens later.

[WeathermanShawn]

Perhaps cut and paste is looking for the matching P/N values which are not there.

Main thing is to use those MAF g/s values. That will probably give you +2 g/s over what you currently have. Seems like every cammed car wants more air then doing it solely via RAFIG. See now your VE, MAF, and Idle air will match...

Also blend the higher ECTS..

[joecar]

The paste-with-labels is looking for all the axis's to match up.

The paste is looking for all the axis's to match up.

I just use straight copy/paste & dont worry about copy/paste with labels. Saves all the headaches.

[joecar]

Len, do what Mick said in post #39... just make sure you line up the paste on the axis's.
