Boostane Users w/ Whipple

[stannypack]

Is it helpful to add boostane to a stock gt stock tune on 93 gas just for safety when pushing it in the heat? not sure if ford's adaptive octane goes past 93

Personally I'd just add a gallon of E85 to a full tank of 93 and that will push you to like e15-20ish and will give you that extra octane you need like using 94 octane. No MMT issues with plugs or sensors or cats.

that's what I'd prefer but the closest e85 station is in MD for me. Idk why northern va doesn't have e85, I'd jump on a flex fuel tune if we did

Not sure where in NOVA you are, but I'm pretty sure there is a station in Woodbridge.

that one's even farther than the royal farms in md for me lol. Now I'm debating that royal farms but I'd be getting under 200 mi per tank the way I drive... time to research who does flex fuel tunes

Whipple doesn’t use octane learning in the gen3. I’m pretty sure no one does. I even tried many different things to get it to work on mine and it seems like the logic just isn’t there in the OS.

Can confirm, it doesn't even work on the stock tune. Not sure why the engineers disabled it, but I guess the direct injection is a hail mary of sorts to stop knock in its tracks so it wasn't needed.

@ice445 you may know this already but the gen3 uses per cylinder knock retard below 5080 rpm and then switches to global above that. If it already has some knock retard at play before 5080 then it averages it out to a single value above that then continues to advance from there. If any one cylinder knocks above 5080 then it pulls timing from all 8. So basically all it takes is a single knock event at high rpm and it will back down all of them. All I can surmise is that ford figures on a single knock event per wot period won’t hurt anything. That’s probably just fine at stock cylinder pressures….

I didn't know there was an RPM cutoff, that's interesting. I suppose it makes sense though for factory programming. I wonder if there's an accuracy reason they chose to do that? Or if it's purely for safety.

I agree though, definitely not ideal for boost.

I don’t know but the Roush blower tune and stock gt500 stays in per cyl knock mode at all rpm. I followed suit but I also tune mine to stop the timing advance short of knock onset.

I wonder if the Ford Performance tune also uses per cylinder at all times

Sounds smart honestly. One of these days I'm gonna get my own HPTuners device and start learning all these finer details to tune myself like what you're doing.

Just below 5080 rpm. I compared the FP tune to stock and I don’t believe they changed that aspect. They basically just calibrated it for the larger maf, larger tb, and higher octane.
