What, my car is different with temperature change. What are your settings.

 

easytherm.

 

I wish I could explain it, but I can't. Our dyno does not log boost pressure, so maybe that has something to do with it.

Remember the Xede is not a standalone. With the standard Xede, it does not have a extra correction based on those factors. It could, but 99% of people do not use it. The stock ECU corrects for those factors.

Steph, doesn't the Xede use pressure+temperature to calculate air density?

 

Nope, it relies on the stock ECU for those functions. The Xede will control fuel, timing, O2 sensor, TPS, WB O2 integration, boost solenoid, and a few other analog inputs you can think of. But it's corrections are based off of the MAF and engine loads.

Here is a copy of the map. It is about mid-range to aggressive on the timing scale of things. What is in the map is the degree of advancement or retard to factory settings.
Stephanie

 

Whats the scale on the left side (y axis)? I get the rpms are on the bottom, but whats the side? kpa?

 

The Y axis is engine load.
Stephanie

 

Engine load? What sensor gives you those values? What unit is that is?

 

Doesn't matter, you still can't figure out what the actual timing he was running is. It varies depending on whatever the stock ECU felt like running. I was hoping for a map with PSIA and RPM for axis and the actual total advance for a number.

 

paging johnwag who knows the stock timing #'s by heart.
