Yes. G1210 set to type 2.
I called the harness guy today. He said the harness wire for starting goes directly to the starter relay, not through the PCM. So pretty sure there is no current, trickle or otherwise, to that PCM pin 67 mentioned.
1.Is this the problem or would your fix have over rided this issue?
2. Should I reapply the vats patch just in case? Can you link me to the how to apply a vats patch? (B9903 in operating system patches, indicates vats patch applied)
Thanks!!!!!!!!!!!!

Thats correct. The ECM does not operate the starter (except in a regular production car), but, the ECM in its normal state for some applications wants to "see" a starter relay and current flowing from the ECM pin to ground through the relay coil.
The current flows from the ECM to ground. Grounding the pin has the same effect.
The "fix" G1220 bypasses the logical check that there is relay current there flowing from the ECM to ground through the relay or directly.
So to check:
You have set the OS VATS patch to enabled and done a "full flash". (this takes 4 - 5 minutes)
VATS Type G1210 is set to "2" (calibration flash only required - this takes ~45 sec)
G1220 is set to "not used" (calibration flash only required - this takes ~45 sec)
Log of it trying to start. Not sure if I did not this right.

All three are in my current file and the changes (vats changes) originally recommended by Taz (I tried with and without Taz's). I am not sure how to differentiate between a full and calibratioin flash but my update from the pc takes 2-3 minutes. All this has been flashed in, I think...
Thanks for all the help!!!!

The full and the calibration flash are selected differently. There are 3 read/write buttons on the toolbar. Green is read. Middle red it cal flash. Right hand red is full flash. And you get a big warning asking if you really want to full flash. Have you been through those steps?
Cheers.
Good stuff. Initially the guys suggested only to use the Middle. Right hand red does the operating system too yes? I take its not possible for me to accidentally change the operating system but no "full" flash yet. I will try today!!
Also very troubled about the -60 spark advance in the log file. I did change the cam and hope all is allright.
Thanks so much.
Yes the right hand button on the toolbar does a "full flash". This is the OS/Operating sytem AND the calibration area. This is around a 2mb flash so takes about 5 minutes. The calibration is smaller at about 256kb. The VATS patch is in the OS so unless you do a full flash it wont work.
Good luck
You can use full flash to change the OS (be careful doing this on E38/E67 ECMs, make sure the OS is compatible with the ECM otherwise you will brick it) or to apply VATS patches, etc. So you need to do a full flash to have the VATS disable actually written to the ECM because of where it exists in the ECM code. Most stuff is in the calibration area, so usually all you need to do is a cal flash. Once you have the VATS patch applied via full flash, you only need to cal flash afterwards unless you need to change VATS stuff again.
