2 general questions for clarity

Post by Fueler »

1: New Burn procedure.
While I understand the need to have individual burn control there is no global burn button.
On a new project what is the best procedure to ensure that everything has been burned?

2: stoichiometric settings.
In engine and sequential settings / required fuel / A/F ratio.
Should this be set for required max load? In my example a supercharged gas engine at WOT. Let's use 11.5 as an example.

In General settings / include AFR Target / stoichiometric AFR.
Is this to be set to match the 11.5 load previously entered or set for the fuel at 14.7?

The burn button is really a global burn. The ECU generally only holds 1 page of tune data in RAM at a time. If you want to change settings on a different data page, that page will need to be loaded, thus what ever is currently in RAM will be discarded, so it you have made changes to what is in RAM that you would like to preserve, they need to be burned to FLASH before they are discarded.
However, for the most part TunerStudio manages this for you. Any time you change a setting that is on a different page, and there are changes to the currently loaded page, TunerStudio will automatically send a burn command before it send the changes to the next page.
Also anytime you close a dialog, TunerStudio will send a Burn command if there have been any changes.

So what this means is there will never be more than 1 page of tune data not burned and that will only be if you still have a dialog open that you have made changes to without yet closing the dialog.

Generally you stick with what is stoich for the fuel you are using (14.7:1 for gasoline), not your target at full load. Then set your boosted AFR targets in your target AFR table.

Thanks
So...
11.5 in Engine and seq. settings
14.7 in General settings

"Then set your boosted AFR targets in your Target AFR Table"
You are speaking of the Fuel Settings / AFR Table 1, correct?
