ACES IV - An effective octane booster and anti-wear additive?

[BND 370 Hemi]

Hi Brian,

After 2 tunes knock is still good.....but I am seeing about a 1.25 degree retard for about the last 1k rpm of third (range .25-1.25). Everywhere else was flat or adding timing.

Do you think I should try the 1 oz to 4 gal ratio like the tt v8 Audis we discussed?

You can try a 1 oz to 5 gallon ratio and let me know how that works with the new tune.  1.25 is not much with an aggressive tune and the heat in that engine.  Try that and let me know how the results are.  We can always go to 1 oz per 4 if necessary although there is at some point the law of diminishing returns here.

Thanks for the update.

Brian

Ok, I've also got colder plugs, stat, and quantum blue coolant to add to the mix which I suspect will help as well.

That kind of knock retard is where I net my best times at the dragway....almost done with a tank of fuel from a not so trusted source (Marathon), spiked a random KR of +1 only once on the entire tank too...corn is my friend!

Only about 6 weeks from winter blend too

Good reminder on the winter blend, Rich.  Should FIC be added in the rotation to the ACES IV in FoMoCo's ride, Brian?

Actually, Marathon traditionally has the second highest motor octane values on the market after Shell.  Top 3 are Shell, Marathon and Amoco...if you can find a pump with the Amoco sticker on it.  If it has the sticker, it is Amoco gasoline and not BP!

I normally use BP, like I haven't used anything but BP for over a year with great success. Couldn't really judge on the overall performance as it has been 90* for the last week...car gets a bit sluggish in the high heat

Low RVP gasoline from June 1 to September 15th nationwide.  After that, we get higher and higher RVP (Reid Vapor Pressure) so much more volatile and more propensity to detonate!!

The ACES IV-FIC is designed for higher mileage cars that definitely have deposits that need to be cleaned out.  His car is new enough to get clean and then kept clean with regular OBD II CANBUS  Tier 2 Bin 8 ACES IV Gasoline Formula.

And please don't forget to use the special nozzle adapter that came with your car or your expensive ACES will be on the ground!!!!

I dropped my first 2 fillup... Used a 1/2in rubber hose for the third but it was a pain to make it pass the flapper.

Where do I get the adapter?

I haven't used the included nozzle. Seems like a pain in the butt. But Ford has the funnels, I think I paid $10-$20 for mine when they were doing transmission repairs. But then I found it here.

Do you guys not have one in the trunk with the spare tire?

Yes. Especially now, it always there.

DX, are you logging learned octane, aka octane adjust ratio?

http://stratifiedauto.com/blog/understanding-knock-and-ignition-corrections-in-your-high-performance-ecoboost-engine/

"The ECU always listens to the knock sensors and knows which cylinder is knocking while it keeps adding timing. Once it starts to hear knock it reduces ignition timing on a cylinder by cylinder basis and eventually it learns an ignition trim that scales the entire ignition table up or down depending on how much knock it picks up. This trim is called the OAR – the Octane Adjust Ratio. Over time, the closer this value is to -1, the more timing the ECU is adding without hearing knock meaning you have high octane and there is power left on the table. The closer it is to +1, the more knock the ECU is picking up meaning either the octane you are using is poor or the tune is too aggressive or both. So having a peek at your OAR using a logging tool such as the COBB AccessPort ever so often will give you an idea of the fuel quality and how the tune is behaving. ***Keep in mind that the tuner has the ability to adjust how the OAR parameter learns so in some cars OAR will sit at one value and in others it will move around more. If you have concerns, bring it to their attention.***"

There is also a switch in the tune to have the knock sensors add and remove timing to individual cylinders or have the spark trim applied globally to all cylinders if any cylinder hears knock.

I would only use the individual cylinder advance for race cars..the risk /reward for a few hp is worth making sure each cylinder is achieving max pressure all the time...a friend of mine that is a respected tuner this is why a lot of coyote mustangs are dropping cylinder 8 because other tuners like to set the knock sensor that way to outperform other tuners...when the ignition is retarded globally to all cylinders when knock is heard is safer

I dont do ANY logging. I've just started using the obdlink mx for reader with the obdlink software. Im having issues getting everything setup. So will be trynna get that going.

I had the OAR working for a bit on other phone, it was always at -1 as I recall. So just trying to get it right. I bought the WiFi version thinking I could use with Android AND IOS if need be. (iPad) But what a pain!
