Operating system Patches?

[oztracktuning]

Can the operating system patches be explained.

MAF Error Patch

Traction Control Patch

Disable Vats patch


In what situations do we need to use them?

good question, I have been wondering the same thing.

[oztracktuning]

The maf error patch expands the maximum limits of airflow - only needed when modifications that give a fair bit more hp occur.

MAF Error Patch

Traction Control Patch

Disable Vats patch


In what situations do we need to use them?

MAF Error patch fixes a table lookup issue in earlier O.S's.
Traction Control Patch fixes the permanent disable of the traction control system when running MAFless.
Disable VATS patch, must be applied because there is no on/off for the VATS like in the LS1 (and most other GM computers).

Ross et al,

Why does the disable VATs patch have to be applied again - is it to provide the additional on/off "buttons" within the tune?

Also, do you know if the MAF table lookup error has any impact on the accuracy of the MAF readings on the LS2s with E40 ECM?

Thanks,

Acer

are these patch's built into the software or is it an additional patch that has to be applied to the file?

Look at the tables B9901, B9902, B9903. Apply those needed, save the file and do a full reflash in order to use those changes.

I beleive you need the commercial scan and tune or workshop to use these patches. For the reason of the full reflash.

So am I correct in believing that applying these patches on a stock mechanicals LS2 isn't a necessity. I did my first E40 last night but didn't want to apply the patches until I checked here first. It doesn't look like I'll need them.
