Since I’m a noob to this. Unless the first two people who tuned it did I would say NO. I’ll have to research how to do that

 

When you say remove 5 degrees from the effected tables? Can you explain better

 

In the cells where you see the regard, usually cyl grams x rpm, that corresponds to the same cells in your spark map....or it should.

If you see retard at 2500 rpm's @ .69g, go to the spark map and take out what is being retarded.
If you have 20 in that cell, make it 15.

If you still see retard, then it's false.

 

The tune in the first post has burst knock still fully active.

 

Then the tune I have in the truck now still has burst knock enabled

 

Here is what I would do, in this order. After each change, drive and log.

1. Copy the High Octane spark table to the Low Octane spark table (providing you are using the right fuel, ie, premium)

2. IAT Spark - Zero it out in all cells from 86 degrees to 140 degrees (this is a modifier table and can add or subtract depending on what is configured)

Now, there are quite of few other tables that can modify spark. The Variable Cam spark table is one. It is a modifier table that can add or subtract what is being commanded in the main spark tables. Alot of tuners will zero this table out and use the main spark tables.

3. Burst Knock - Think of this table as the red-headed step child. If you're sitting at a redlight and jump in the throttle, burst knock will pull timing because it sees the influx of air across the MAF as something being wrong. Zero out the Base vs CylairDelta table to disable it.

Let us know.

 

The purpose of burst knock is to account for a potential knock scenario during an airflow transition after the fueling has been scheduled and/or delivered by the ECM and there is either no time to deliver a makeup pulse from the injector or makeup pulses are not enabled in the calibration. If an injection is delivered and suddenly a pressure wave enters the cylinder before the intake valve is closed, suddenly it goes lean and knocks because of the excess spark advance. Burst knock prevents this from happening. It is a good feature to have.

That said...none of the knock in that last log file looks like burst knock. It isn't happening on air transitions, which is the primary criteria for burst knock to become active.

 

Ok I'll will start with number 1 at lunch and log it.

 

o I did number one and drove it around at lunch. No KR while just cruising but I did get 4 degrees of KR the two times I got on it.

 

It sure is commanding a rich AFR for a NA motor, 11.0-11.3 is pretty fat.

Lean it out some to like 12.0-12.3 on pump gas, many times running too rich at WOT can cause knock too.
