Where's this extra timing coming from?
LV8 vs Coolant spark bias = 20.04
Spark reference angle = 5.98

So PLEASE explain this.... Why do I have 35+ degrees of advance?
PS: I just tried burning a new chip using a stock apyp bin and the same thing is happening. I figured it could have been my hacked wbo2 bin doing it, but I guess not...

I have got only 3 days to sort this out. The return to college and end of summer ran up on me pretty quick. I am puzzled about this. This has to be a bin issue, correct?
EDIT: I need to know for certain that the coolant temp spark correction bias is definetely 20... It seems if the bias was around 10, this would make sense where the extra spark is coming from.

The idle stabilizer SA and/or after-start SA can scew the timing this much? I wouldn't mind, but the vortec heads do not like that much timing.

There is a 20-degree bias, but the table you listed has the bias removed. The LV8 axis goes higher left to right, and the coolant temp axis goes lower top to bottom, so at 184 deg. F (between the 3rd and 4th rows) the amount of SA added is zero. The table is used to add timing at really cold temps and remove some timing at really high temps. In the ARAP and other 6E bins, only 10 degrees of SA is added at the low temps (the bottom 3 rows), then 7 degrees the next 2 rows, then nothing added or removed until the top row.

I wish that was the case. But aldl spark adder is disabled.
My version of tunerpro rt has the bias value listed under constants. The table is seperate. So if my bias was set to zero, you would see 20 filling in the upper part of that table.
Technically, this is the table:

I got some new fuel to add...
Both yesterday and today, the timing is correct untill I drive down the road for 2min. And then it skyrockets - out of nowhere! Now, if I were to restart the engine, it would retain the skyrocketed figures. This is odd. It almost seems that when the computer "resets" itself, it retains the correct amount of timing untill I drive down the road??? When i say 2 minutes, I mean almost exactly that.
BTW, engine was about 185 degrees when it was correct.
EDIT:
Take a look at the attached Text document. I saved the csv file from the datarun to text because TGO won't let me attach a csv file.
The timing took it's wrong turn at sample 695. I really hope someone can make sense of all this...

Please

Could I possibly have a defective ECM? Or is this definetely bin related?

It seems that when I set my bias value to a higher value, evrything but idle seems to have close to correct SA.

UPDATE: Ok, I just tried burning the chip on a different laptop and got the same story. I can't believe no one else has had this problem!
I start the car and timing is low even though I look at my spark correction table and there shouldn't be any correction. It then runs and almost reaches the right SA. Then, a minute later, timing skyrockets in the 40's. What is the problem here? Could this be a bad chip buffer or a bad ECM? How could I find out.
Also, lately, my engine is making my radar detector go off... It reads LASER and I start looking around to find no one. This related somehow?
I guess my older thread was the start of this problem.
Check it out.

I need to make a 3hr drive up to school with this car in 3 days!!!!!!
If the bias value listed in tunerpro under constants is set to 20, then is my table correct?(the first one with the zero's)

OK, I know what you're talking about. 
There's a variable called Coolant Temp Spark Correction Disable Temp that sort-of disables the use of the LV8 vs. Coolant Spark table above this disable temperature. In the ARAP bin, it is set at 112.5 degrees F. The SA below this disable temp is controlled by the table, although it does add a few to several more degrees based on the amount of throttle. Once the disable temp is exceeded, the main SA table is now used, but if the LV8 vs. Coolant table has values that are more/less than the bias amount, then that amount (more/less than the bias) is added to the main spark table. This is from what I figured out a few years ago. I played around with the values and tables to tweak it, but forgot what I did and why.

Alright, my Coolant Temp Spark Correction Disable Temp is set at 130.10 which is the stock disable temperature for the APYP. My timing is out of control!
Lets say the following arguments and conditions are met:
Coolant Temp Spark Correction Disable Temp = 130.10
Coolant Temp Spark Correction Bias = 20.04
Actual Coolent Temperature = 174.65
Engine speed = 2000RPM's
Engine Load (LV8) = 104
Spark Advance table value according to the previous LV8 and RPM = 34
Actual Spark Advance to TDC = 43.24
I was under the assumption that you take the Coolant Temp Spark Correction value and subtract the bias value. Now you add/subtract that to your main SA table.
If the above were true, 20-20+34 SHOULD BE 34!!! WHy do I have no control over my timing???

Does your knock sensor work? Does APYP have a forced knock test?

Does it function? -yes
Does it function properly - I don't know
I get KR at anything above 3800RPM's no matter what my timing is set at. I did notice that the single wiring leading to the sensor got melted from the headers. (The insulation, not the wire itself) I guess I'll fix this tomorrow to make sure this isn't causing my timing problems.
How does the Knock Sensor come into play here? What are you thinking of RednGold86Z?

I'm confused...
My knock sensor works. I even put in a new wire going to it just to make sure and I cleaned up the connections.
I still don't know how this extra timing is coming in. To make it driveable, for now, I made the following changes:
Coolant Temp Spark Correction Bias = 30.59
Coolant Temp Spark Correction Table =
Doing this, Things are pretty accurate and nothing fluctuates. WHY!!!!???

Start from scratch. Do the MINIMUM amount of changes (like injector constants, and ALDL to 0, only, if you can), and just see if the problem goes away. Then if it's gone, start bringing in your other changes one area at a time, and see where it goes bad.

That's very interesting...
90C = 194F - which is around where it goes crazy. So it's saying it purposely adds 10d of SA to test code 43 which is the ESC. So, wouldn't unchecking the ESC Diagnostic Enable(code #43) flag(In Tunerpro RT) act like a test to see if this is what is messing things up?

That's very interesting...
90C = 194F - which is around where it goes crazy. So it's saying it purposely adds 10d of SA to test code 43 which is the ESC. So, wouldn't unchecking the ESC Diagnostic Enable(code #43) flag(In Tunerpro RT) act like a test to see if this is what is messing things up?

Use this XDF, see if the tables that you're looking at read the same. Also, don't use the 10k resistor. Also, use a timing light to see if it's really true. Also, try getting another bcc stock bin from moates, maybe AUJM.

I still cannot figure out where the extra timing is coming out of and I would really like to use my wideband hack with the apyp bin. Everey other bin or bin type works. I even tryed downloading the stock apyp bin and only changing the inj. constant and still I'm getting 10d SA. wtf?
