AutoVE FI Script - Comments Please

[405HP_Z06]

Hi All,
I'm working on an update to the AutoVE tutorial. One aspect that I am including are scripts to perform the needed modifications in addition to the written instructions and pictures.

Here's my first crack at the forced induction AutoVE script. Please take a look, test, and let me know if anything looks or works incorrectly.

Thanks in advance, see the following notes:

When I tried to run the script, I only got as far as the third step and it hit an error and stopped. I removed "284" from the script and re ran it. The scrpt only changed the first row in B3605 The script went up to command 9 and stopped again. it said

Label 400 not found in
000090=B5913 "0.08,400,1.20,8000"

405HP_Z06: Copy the last column of the Main VE table (105kpa) into the first column of the Boost VE (105kpa) and the last column (285kpa). Increase the last column (285kpa) by 150% and do a linear fill from 105 to 285kpa.

EDIT: Oops. Realised this isnt for a custom OS

This isn't a custom OS, stock 04 Escalade 6.0L

Can you post your stock tune? I tested on the attached tune for the same vehicle and it ran fine. The units must be configured correctly in the Tune tool.

I was looking at that and didn't have time to add to the initial script. I'll add this, thanks for the feedback.

Done, scripts updated. Thanks again for the feedback.

If the tune file was from the holden site, I put it there. I downloaded the file you used, compared it to my stock file then downloaded your script and ran the script to your downloaded file. It went to #3 again and gave me an error

Label 284 not found in
0030= B3605 SET B3605 "20,-40,100,284" . EQ Ratio When In Open Loop per [B3605] section below.

In looking at the detail in the scripts, there are some minor differences in B3605 at the 0-40 deg ETC and MAP over 60 in the 50 deg + the changes are very slight.

The big difference is the spark table. B5913/5914 B5932/33

Anyone have an idea of why th script does not work. Is it a problem that I am using V1?

Do you have all of the units configured correctly in the Tune Tool? If the units in the script and Tune Tool are different you will get the error you describe. The script works perfect against the Escalade .tun file I posted earlier.

Here's the script execution log when ran against the .tun file posted earlier. The only one's that didn't execute were the COS specific commands:


All the modifications to the .tun by the script:


Select the 'Units and Precision' button on the tool bar:


Now scroll down and find {B3605}. It should be configured as shown:


Sort by each column heading 'Data Units', 'Col Units', and 'Row Units' and ensure they are all in (F) Fahrenheit.


I've attached a .tun modified by the script for you to compare against.
