Greetings! Trying to familarize with this tool. Lots of information & haveing a bit of a problem trying to figure out why logged timeing isin't matching what I programed in the octane map. I overwrote & matched HI to Low maps. Commanded 25 degrees @ WOT & seeing only 20 with no knock issues. What do I need to bypass or alter to make this happen? In the search section I'm not haveing any luck finding this basic info. Regards Lou
Welcome!! More then likely you are having timing pulled by either your IAT vs Spark, ECT vs Spark, or a transmission Spark setting. If you can post your log up, we can take a look at it and give a better idea of what is happening.
You should log ALL the spark "DMA" PIDs.
You can find them in the Scan Tool [PIDs (F8)] tab page, by selecting "Spark" in the System drop down list box.
Select and log the following PIDs:
SAE.RPM
SAE.TP
SAE.SPARKADV
GM.KR
EST_BTM_DMA
EST_KRB_DMA
EST_CAT_DMA
EST_ECT_DMA
EST_EGR_DMA
EST_EQR_DMA
EST_IDLE_DMA
EST_IAT_DMA
EST_NR_DMA
EST_SMT_DMA
EST_TRQ_DMA
EST_TRAC_DMA
EST_XMSN_DMA
NOTE: these PID names are listed in the right-most column. When searching for PIDs, you can click the PID column headers to sort the PIDs by that particular column. Each click resorts the list either ascending or descending.
One or more of those spark PIDs should show you where timing is being pulled.
You can right click on most of them to get "More info...", usually the "More info..." tells you which table in the Tuning Tool can be used to alter that particular spark's contribution to the final run spark.

Here is a good thread describing what Paul is refering to.
