Northstar PCM History
1996

This used UART for communication with the ABS/TCS module only this year
This ran 4 O2 sensors
This had 2nd gear starts with TCS turned off
It had no FTP sensor and used a purge switch
This uses a Brake Booster Vacuum Sensor
All of the cars used a VATS system in the IPC and Class II from the IPC to the PCM.

The domestic calibration package = United States, Puerto Rico, U.S. Virgin Islands, Caribbean and Guam.
The Unleaded Export calibration package K29 has some DTCs disabled and others have changed types (Type A to Type D, etc.). If a DTC has changed type or is disabled for the Unleaded Export calibration package. The Unleaded Export calibration package consists of vehicles sold in: Canada, Asia, Korea, Taiwan, Japan, Europe, Israel, Mexico, Iceland, South and Central America and Fleet/Govt./Military.

1998 & 1999

The Deville’s and Eldo’s still use VATS system.
The Seville used a PKIII system and an enhanced Class II system
1998 did away with the Brake Booster Vacuum Sensor and the Purge Switch.
They added a Fuel Tank Pressure Sensor
1998 switched to 3 O2 sensors.
I have found that some export programs will not start in Seville’s. I have not tried them in Deville’s with VATS

Thanks CalEditor. The one you show as 2004 & 2005, does that do trans as well? I have a couple of those, one black, one not, but the same service number.
I also have a Siemens TCM that was supposedly from the same vehicle, but I was under the impression the 2004-2005 engine computer does trans as well. Why else would it need 2 x CPU's!

Cheers,
Ross

You're not wrong, there is a bunch of posts.

Ross,

TC (John), has packaged his software and customized it for a number of vendors.

Jet Performance Products have purchased gas and diesel rights to the software. In doing so, the original unlimited version of TC was taken from the market. A limited number of original TC customers are still supported via John directly.

Westers Garage (Lyndon Wester) has a version of the TC software customized for his customer bases. Westers has also supported a scan tool (PCM Scan) to work with the TC OBD2 interface. I would imagine this is what you see.....Correct Tom?

Flash Chips (Ed Wright) may have a version of the TC software as well. Don't know much about this or if this information is correct. I have seen a version of the flash utility in the flashchips colours...

The Only other Tuning Software I know of is the Real Time Roadrunner software supported via Craig Moates, God bless his mortal emulation soul.....LOL..Yep once you tune realtime it hurts to go back.

MxScan (James Brimson) supports the Monodax forum and the MxScan scan tool software. I earn for the day that further developments in this software are made public as the GUI layout looks interesting.

Until then, I will enjoy the use of EFILive.....

LOL.

You are a funny Man Ross!

I tried to send you a PM but you obviously get hundreds of them as the return I got was that your mail box was full....TT.

I was wondering if you could send me a copy of the 0411 Shelby Tune you have?

Looking at new things is a passion I have.
