Tuning questions or opinions

I'm curious to know if the drive mode function in a premium model has any use once you install a tune?

Not following this one....?

The drive mode allows you to choose between normal, sport, track, and snow/wet. I am asking if tuning the car has any effect on this feature.

Ahh...all of those features still work with the Cobb/MAP tune, I had the same questions when I bought the MAP tune and was told by Adam/others that those functions are suspension/brake related and not tune related.

I have had a tune from Steeda, Unleashed and the SCT canned tune on my EB and the driving mods are not effected. They work just like they do with the stock tune. Can't say what all tuners do but can't imagine them defeating the driving modes.

I have the unleashed tune and it's not affected

Fortunately Cobb is in my backyard. I'll be heading there tomorrow for my AP.

The driving modes shouldn't be affected.

I understand the lower temp stat. but I also understand that this could increase the fuel supply due to the lower engine temp... can one of you tuners tell me when the engine goes into normal operating temp mode and does not/stops adding fuel for a cold engine.. I don't want to run a stat that will make my car continuely run in a rich state due to temps.
Thx...

Great questions and concerns here! The Mustang EcoBoost introduced new code and thresholds for this very subject. The fuel system considers 160F to be "warm" but will utilize a slew of "cold" tables for blending all the way up to 159.99F. The default t-stat opening calibration is set for 180F with the target ECT at a healthy 215F. Running the vehicle with a lower temp t-stat without appropriately calibrating these thresholds may result in an overuse of fuel and increase emissions output. Not to mention there are several other compensations that monitor and rely on ECT to reach operating temperature to activate.

Tuning for the drive modes is accounted for in our OTS calibrations and is available for modification in our Accesstuner software. The Mustang EcoBoost has several newly added features that utilize the current drive mode as an input. One of the exciting ones is an alternate shifting profile, consisting of hundreds of separate tables dedicated to the Sport+/Track mode! This allows "Drive" mode to be calibrated for a tame street experience, and everything else to be aggressive. It's almost as if Ford read our minds and saved the hassle of having to inject new code for you guys!

One of the first tables I thought of was ECT (Engine Coolant Temp) Compensation for timing when I was reading this thread. The ECT compensation table has higher ignition values the lower the ECT. So if the coolant temperatures drop ignition timing will be added, and if not tuned properly could induce knock.

Put on my mmr intake tonight. My iats at idle are extremely high. It's 66 degrees out and my iat is at 128 degrees. I don't ever remember my stock air box ever getting this high

 

[Zuul]

While riding around it cooled down between 68 to 70 degrees. But at idle for 5 minutes it shoots way up.

It didn't take long to cool down after I got back on the road. But I believe I can notice a difference since I installed it today. I was really leary on modding this car but I've done a tune and this intake within the two months I've owned it.
