ECT button is a TUNE.

I cannot believe the difference in power and acceleration with the Ect button on especially with 93 octane. It’s unreal how much pull this truck has once it’s revved up with ect on. Anyone else feel same way??

 

Factory tune. Works fine. However, it was not designed to separate your money from you like the other tunes.

 

ECT and octane have nothing to do with each other

 

ECT is good, but the main problem is that the 4th to 5th gear shift happens at over 60 mph, which kind of sucks in city driving. I prefer to just use S4 or S5 and step on the gas a little harder.

 

Disagree

 

ECT button does nothing except change the shift points. 93 octane does nothing except give you a placebo effect.

Use what the operators manual says to use for fuel, and use the ECT if you need a bit more acceleration by having the shifts come in at a higher RPM

 

friday post?

 

Well, you're objectively wrong lol, so I'd like to hear your scientific argument on this one.

 

I found this article mostly entertaining and slightly informative

I think you’re the only one. Plus, you need an actual ecu tune that’s designed to run on higher octane gas for anything to be noticeable. The 3.5 engine is designed to run on 87

 

These engines were tested with 91octsne according to owners Manuel

 

Edit: this is better

 

Hahah you got me

 

I see we have a spelling bee champion. I guess you didn't like my post, as it was deleted.

 

I think one of the local tune guys on the forum would know.
I don’t think the ECT button has any affect on octane.
The ECU will compensate for octane whether the ECT button is on or off.

@JustDSM or @tonered will likely know the answer.
I am not here to argue. I am here to learn and get the correct answer.

 

OVTune has stated several times that the 3.5 pulls timing like crazy on regular gas. That would elude to it pulling timing less with premium as its less likely to knock/predetonate.

 

These engines run better with 93 . This my 4th third gen . I can notice a difference right away

 

It just changes the shift points. The engine doesn't care if the tank is full of 87, 93, or sawdust.

 

No doubt.
Generally the more you can advance timing, the more power you will see.
To a point…..

 

I haul around a 4cyl in the bed of my truck with 93 in the cylinders for an extra 100hp
