ok,
Cable finally came today..

ran DM and did a run... can anyone tell me how this looks to you?

Why is my sparkknock count so high? How much timing advance should I have?

I am so green to this it is ridiculous!!
I am reading Injuneers's tech page on it now..

If some of you gurus could just quickly scan this file, it would be most appreciated!!

Thanks so much in advance!!

 

Knock count is a cumulative field. It increments up based on engine operating conditions, and does not affect knock until the PCM detects knock via the knock sensor. It isn't unusual for knock count to increment up a couple thousand on startup. When it reaches the maximum number that fits in the binary field, it resets to 0 and starts incrementing all over again.

Focus on "spark retard", but watch knock count. The first incident of spark retard (record 2032) is 13deg, but that is a data error, as indicated by the red flags at upper right "data err". That is often due to interference on the data wire from the PCM to the ALDL connector.

Later (record 3399) you get spark retard when you let off on the throttle, and the knock count increments slightly. That is very unusual, and isn't hurting performance. At record 3650 spark retard begins at a low level, and peaks again at record 3678 when knock count increments. At that point you are near WOT. That is costing you power. Happens again later. You need to work on figuring out the cause.

Spark timing is set by a table based on RPM and engine load (MAP). Your numbers appear to be stock. There is an example of the stock timing table in the writeup you were given the link to.

In power enrichment mode (roughly, WOT) the O2 sensors are indicating its running a little leaner on the left side than it is on the right. Always a diffcult call, because the O2 sensors aren't particularly accurate at the richer A/F ratio used at WOT, and the stock programming is richer than it needs to be anyway.

The PCM is using the long term fuel corrections to add about 12.5% extra fuel on both sides in the high load/high rpm cell. Might want to check your fuel pressure, and make sure the MAF sensor is clean.

At idle its adding 3% (left) to 6% (right) extra fuel. That's not a major issue.

MAP, TPS, IAC, MAF flow, coolant temp, IAT, idle speed, system voltage, spark advance all look normal.

What is the specific problem you are trying to track down? Other than the spark retard issue, and the PCM's need to add fuel under high load conditions, I don't see any indication of problems. If that is correct, focus on the long term fuel corrections and the spark (knock) retard.
