So my resusts of 2 stroke oil are turning out to be awesome. I'll get some proof this weekend on a 400 mile trip.

Think this would mix well with a full synthetic like Mobil1? Also what brand do you use?

Thanks and enjoy the trip!

I'm using Royal purple synthetic 2 stroke oil. So far I found I need to cut my dosage back. For the first 160 miles there were hills that would require around 4-6 psi of boost in 6th gear. On those hills I was getting knock around 2-3°. So I filled the car with 8 gallons of 91 (all I could fit). On the last leg of the trip the knock was no longer there on the hill climbs. So 1 ounce for every 5 gallon is to much. I'm going to cut the dose in half next tank.

Look forward to your next report, wasinger

I was running 2 gallons of E85 and the rest of the tank with 93. Went to fill up yesterday and I did 1 gallon E85 and 13.4 gallons of 93. Driving today my learned octane ratio on torque is about 106 but off the line sometimes my knock says -0.2 and others it says 4.5. Whats up with this I'm running a 93 tune so I shouldn't have any knock with E85 should I? Also if I accelerate hard in 5th or 6th gear (S mode and slowly put pedal to the floor) I get about 3-4 knock which I think should be normal, let me know if it isn't.

Hmmm. I keep watching learned octane ratio and even mixing it never changes. What are your trims running at?

Still not sure exactly what trims do or how I'm supposed to report that to you. Will the max value always be WOT or will it always be idle? Do i just have to stare at my tablet while I'm accelerating WOT because I don't really want to do that.

As for the LOR I have had values from 99 to 107 and I have only used it since I started blending.

Do you have an OBDII/Elm.327 device?  Do you have an android device?  Load Torque software on it and log.  You don't have to keep an eye on fuel trims, you can look at it in the log once you get home.

Fuel trims let you know if the car is adding or subtracting fuel to maintain the right air fuel ratio. If the number is too big you could be running out of fuel or have a vacuum leak. I never see knock at WOT with or without E85 so you may have something else going on?

I had the same situation as sunwolf. Getting knock on heavy load% in 5th -6th gear.
I sent Torrie a log of load,rpm and knock and he corrected it.
Since the tune update I've seen 0 + knock. I'm running 93 gas in my 91 tune right now.

Its not exactly WOT its going 70 and locking it in 6th gear by using S instead of D and pressing the pedal all the way down slowly. It gives a good impression of how much torque the car has, at least in 5th gear, because once the boost builds it is still fast no matter what speed you start from.

Did you just start monitoring recently?

Knock sensor wires checked?

By locking it in gear when it would usually downshift doesn't sound like the most beneficial thing for the car. Almost replicating glock-coma's, if I remember correctly, non downshift syndrome.

Did you use that BP we talked about?

Yes I used that BP. I did 2 tanks of blend and now I'm running a tank of 93 to see the difference.

The ECU doesn't fuel trim at WOT or under load or before the engine reaches operating temp. It falls back to a predetermined set of fueling tables, ignoring O2S data, also known as closed loop operarion.

Mine does not go open loop during WOT.

Only goes into open loop for a few seconds at startup and during decel fuel cutoff during an off throttle lift.

The behavior is the same stock or tuned.

 

[IHeartGroceries]

Can you make corrections to the second sentence? I am not understanding what you mean.

Anybody with a pre 13 model want to verify?

Seems rather risky, if 02S sensor data is inaccurate, or if there's sensor malfunction.

I've heard of total open loop tuning, by aftermarket solutions. Never the opposite. Especially by OEM.

Sorry, hopefully its clearer now , on the phone and on the run at work....

Is this based on data a scan device is reporting?

Can anybody else report? Specifically pre 2013?

Torque, Dashcommand, and OBLlink all show closed loop during WOT.
