VATS Thread

[Caleditor]

I hope this thread ends all of the misinformation and allows tuners to properly turn off VATS.

I currently have a PCM from a guy that had attempted unsuccessfully had is VATS disabled by 2 other tuners. One of them I would consider a friend in the tuning market of mine. I have worked with this tuner and have NEVER seen an issue on one of his tunes. This tuner offers the same services that we do including the dealer program.

I hope to take this to a new level

And
YES it will be in HEX

I don't have all of the answers, but I hope that we can compile information in this thread

its all pretty simple, they either give you a flag that's compared and a branch that jumps over the injector disable stuff, and if that doesn't work, you just patch the jump so it always jumps (or doesnt or whatever).. or insert a jump somewhere?

not sure how much more "properly" you can do it?

If that was the case then VATS or PK2, PassLock and PK3 all work the same way. This is not the case.

I am going to use a 1998 V6 calibration

I was away from my laptop and was unable continue earlier. I have a document I will share at some point in this that I have created about GM's VATS also. It is not completed yet

From what TT has made public we know these parameters for this VDF

intDevID	txtCalToolParameterName	txtHexAddress	txtCalParameterTitle	txtCalParameterDescription
25-2	KE_VTD_IS_DISABLED	0007C948	VTD Is Disabled	This determines if VTD is disabled on this vehicle application. The value TRUE disables VTD. The value FALSE enables VTD.
25-2	K_VTD_Auto_Learn_Timer	0007C956	VTD Auto Learn Timer	Time allowed for auto learn procedure.
25-2	K_VTD_Auto_Learn_Counter	0007C95E	VTD Auto Learn Counter	# of cycles to complete for auto learn procedure

We know a little bit more than that.

KE_TCS_CAT_TEMP_FOR_NO_BOOST	0007C7F4	Catalyst_Protection_Boost_Shutoff	If Catalyst temperature exceeds this value, then open Boost Solenoid to prevent catalytic converter overheating situation.
KE_SF_PULSES_PER_MILE	0007C93A	Pulses_Per_Mile	The pulses per mile variable is used to calculate the MPH of the car. Adjusting this variable allows you to adjust for tire size variations.
KE_VTD_IS_DISABLED	0007C948	VTD Is Disabled	This determines if VTD is disabled on this vehicle application. The value TRUE disables VTD. The value FALSE enables VTD.
K_VTD_Auto_Learn_Timer	0007C956	VTD Auto Learn Timer	Time allowed for auto learn procedure.
K_VTD_Auto_Learn_Counter	0007C95E	VTD Auto Learn Counter	# of cycles to complete for auto learn procedure
KE_MAX_PRESSURE	0007CCEC	Max_Shift_Pressure	Max allowable force motor pressure used for limiting calculations.

In the orange is the VSS PPM. After that is VATS and the green is a table way before the Max Shift PSI.
My point is we are lacking information

These are all 1998 V6 PK2 and not PassLock

YES I ran 0's on the first line
This is 100% OE for a 1998 Riv


This is 100% OE Olds 88


This is 100% OE LeSabre



This is 100% OE Camaro and the PK2 is different on the F-Body's

[Caleditor]

This is a PassLock that is also Serial Data instead of Circuit 229 or PWM

This is 100% OE Olds Intrigue with PassLock. The Fuel Enable password is sent over the Class II serial data line


I will post up a 100% OE Grand Prix PassLock that has a 229 PWM fuel enable circuit in the morning
