They go by many names, P01, P59, VPW, '0411 etc. Also covering E38 and newer here.

To clear the mistery vats settings.


On 512kb there is

0 = Serial Vats
1 = PWM Vats
2 = No Vats

On 1mb there is

0 = Serial Vats
1 = No Vats

On some of the next release of universal patcher it should be fixed for 512kb. Current setup only treats 1mb pcms with

0 = Serial Vats
1 = No Vats

I also suspect vats byte is read at hard boot and stored somewhere, and soft boot doesn`t affect it later.

Thanks for this! Looked a few places and couldn't find this information, to confirm this is indeed correct? Also if so do you happen to know why on a 1mb pcm I set to 2 and it seems to have worked. The same bin that I shared previously. I mean it makes sense given serial is a newer technology correct? Meaning pwm would basically be obsolete on these newer vehicles? Complete speculation on my part just curious.

Basically anything over 2 will work too, since the code works that way. Some boolean checks.

The pwm is phased out on 1mb since there is no more platform usage for it. F-bodies used PWM and maybe some others too but they got dumped in 2002.

Awesome kur4o, Thank You much ...

So, if it's boolean, 0=false=Serial and anything else equals true or off on the 1m ...

Cool Cool, thanks for the explanation! So anything over 1=No vats but typically 1 is what you want. Learn something new everyday, Thanks!!

I suspect this is a miss wording, not a misunderstanding ... It's anything over Zero = No VATS, i.e. 1.

Now that we are on this subject I've been looking a bit deeper into my '03 Grand Prix VATS setting, It's a 512k P04b.
An un-confirmed GM doc shows this: VATS (0=Enabled 1=No Light 2=Disabled) :wtf:
