Help figuring my log out

[zbadestz]

Just a couple questions. My car is 08 LS3 A6 Vette..... E38/T43

This run I did

60'....1.63
330...4.303
1/8....6.549
MPH...112.93
1000'..8.467
1/4.....10.06
MPH...140.25


Why are my gear changes lined up with the rpm?

Is there a way to cut out the run in the log and set time to line up with time slip?

My mph is not the same maybe from my tires growing when going higherspeeds?

Can the tune file be switched to mph vs. kmh?

Iam recording using BBX....... If I use my laptop with is record faster or better?

How many can you log BBX and Laptop before it lags or too much?

Heres a copy of my run

I'm swamped, I'll have to take a look over the next day or two...

[joecar]

In the tunetool go Edit->Configure Display Properties...

hint: click on the column headings to sort/group units so you can select a slab; then go rightclick and select change the units for Data, Row or Col.

When finished, click ok, restart the tunetool.

Thanks JOE. Im trying to understand does the car shift by RPM or Speed first. I have M&H racemasters and I know the grow alittle on higher speeds that probably why the end of the 1/4 there is a 10 mile difference.
If you look at my log you can see shift points are not at redline.

Also you can see throttle shut here and there

Any opions?

Thanks Drew

[joecar]

Both WOT MPH and WOT RPM have to be met in the tune before the PCM triggers the shift.


Is the throttle physically shut in reality...? If not, then something's wrong with the TP sensor or its wiring.

[zbadestz]

Dd you get a chance to look at the log?

[zbadestz]

so if the rpm is reached but not the mph it won t shift till it hits mph?

[joecar]

In your log you can highlight the portion you want to keep and click the Crop button at the bottom (the button on the far right; hover over it to see the text hint), and then save the log as a new file.


Did you figure out Metric/Imperial units in the tunetool...?


Looks like you got wheelspin on upshifts.


In BBL you select as many pids as you want as long as the pid meter on the bottom of the config screen does not turn red (red means too many); it should not lag, from your E38 your V2 should be reading 40 frames/second (which is what I see in your log).


Your trims tell me your airflow model (VE/MAF) is not tuned; also, do you have the various tables for your injectors...?

[zbadestz]

Yes I got the units changed......... Thank you

Yes I did feel some wheel spin

My car is speed density tuned could that be why?

What tables for injectors?


If you look at 3rd to 4th gear change was at 6550 rpm (tune is set at 6900) and 117mph on log but it shifted right at the quarter t 6900rpm in car

Just wondering why the timing is off. How many pids can be logged before lag occurs?

Thanks for your time Joe

[joecar]

Do your upshifts feel firm or loose...?

[joecar]

I don't know if GEAR is lagging behind or if the shifts are delayed.

[zbadestz]

Shifts are firm...

What do I do on gear?

[joecar]

so if the rpm is reached but not the mph it won t shift till it hits mph?Yes, both have to be satisfied... (at least with the LS1/T42, this is T43 but I believe it is the same).

this was a 9.96 pass

[joecar]

Cool :cheers: I like sub 10 quarters :) (even tho I'm nowhere close).

[zbadestz]

Any other pids I should be logging?

WHat can I do about gear being off?

[zbadestz]

Yes, both have to be satisfied... (at least with the LS1/T42, this is T43 but I believe it is the same).

So if I set rpm lets say 5000 it wont shift till its hits set MPH?

[joecar]

So if I set rpm lets say 5000 it wont shift till its hits set MPH?If the MPH is at an RPM that is higher than 5000 (i.e. MPH:RPM gearing relationship), yes, correct.

[zbadestz]

Is there a pid that measure feet?

[joecar]

Is there a pid that measure feet?You mean distance travelled... no.

You would need a log of VSS starting from a standing start, then you could write a calc pid to convert VSS from MPH to feet/second, this gives you a log chart of VSS[ft/s] vs time[s], you can calculate the area under this curve to obtain distance travelled...

it might be easier to do in a spreadsheet.

[zbadestz]

In the tunetool go Edit->Configure Display Properties...

hint: click on the column headings to sort/group units so you can select a slab; then go rightclick and select change the units for Data, Row or Col.

When finished, click ok, restart the tunetool.

Joecar ii did this on one laptop and cant get it to change to MPH on the other.

[joecar]

Post a screenshot of what you tried...

Now which ones do I do from here?

I right clicked data units and tried every options.

Als did the sameaross the top colums

[joecar]

Highlight (use SHIFT and leftclick) all the ones that have KMH in the Data Units column, then on the highlight do rightclick->Imperial.


Then, click twice, on the column heading "Col Units", highlight all the ones with KMH on the Col units column, do rightclick->Column Label Units->Imperial.

Then, click twice, on the column heading "Row Units", highlight all the ones with KMH on the Row units column, do rightclick->Row Label Units->Imperial.

Then click ok to close the units configuration window, then restart the tunetool.
