Does anybody had any good setting in Xcal parameters as in air/fuel, spark and WOT?

Can you alter them without causing damage to your engine?

I got mine from AA but I want to know if it's possible to change these parameters since I have modded my 2006 Mustang already with C&L CAI/AA Xcal tuner, throttle body spacer, JBA titanium shorties, true dual exhaust and Cobalt ignition wires.

 

Call AA, give them your mod listand get a new tune file emailed to you.

 

I wondered about the same thing. Everyone said to just leave them alone but I justhad to try it for myself. Nothing I did made the car run better. Most of the time it ran worse. Brenspeed had it set right where it should be. My recommendation, leavethe air/fuel and timingalone.

 

Definitely leave the A/F and spark parameters alone unless you are an experienced user and know exactly what you are doing and have the proper monitoring tools... You could probably adjust the shifting parameters with minimal risk... but I think Lidio's tunes are pretty good where they are at...

Main thing I use the parameters for is tires size and axle ratio... I also firm up the shifts when I go to the track...

 

You can change the spark timing. 0-2000 to 4 and 2000-4000 to 2

Thats what I have on mine. It was recomended to me by breenspeed to get more out of my car.

 

I tried 0-2000 at 2 and 0-4000 at 2 and I wasn't liking it...dunno..
