3.3TT Stinger Misfire

[STINGER]

its worse, all cylinders are now misfiring

That orange coating on the plugs is from the boostane, it will cover everything in the cylinder all the way out the turbo. Boostane and the like are good at raising octane but they contain MMT which does reduce the plugs life. Anyways, it wont change your path to trail and error this issue out. You need to put new plugs and remove the Lap3 and run straight 93 to see if the issue goes away.

What octane and map are you running?

100 octane I have misfire on all maps. ( including user mode *91 and stock mode )

Take off the tuner and put normal gas in the tank. Replace the plugs.

 

[Stingerr]

Not familiar with Lap 3 but if still happening after setting to "stock" and you have changed plugs already and coil paks, get a torque wrench and check torque on plugs.....also, what are you using to gap plugs?????? Since you are using different plug mfg, what you are using to set the gap may be the "common denominator"

I’m using Feeler gauge

 

[Stingerr]

You shouldn't be running e85 in a car that isn't designed for e85. Take the lap 3 off, replace the plugs with a proper gap and run 91 or 93

E85 is not the problem in my another stinger I have used e85 mix 91 since day 1 when I bought the car (5G e85 )for 2 years every day using map 7 AP tuning box without any problem now has 153k miles zero issues

It might be the tuner itself. Maybe it is defective.

The car was running fine with the AP chip but the reason I decided to buy it the lap3 was because of the Speed limiter Delete
Well, I already adjusted the map several times and I still have the misfire,

Only option left is to remove the chip. If issue continues, return to dealer for warranty.

1. The car is not a flex fuel car.
2. He is not using jb4 with fuel wires for e85

 

[monusa]

Didn't someone already say "remove Lap 3 and put things back to stock"???? Would have been first move after first sign of misfire......

The car doesn’t need to be a “flex fuel” car to use flex fuel. There’s nothing inherently wrong with blending e85 in this car.

He doesn’t need to use a JB4 to use flex fuel. Also, the JB4’s fuel wires aren’t for e85. They adjust the signal for any fuel type to lean out the fuel mixture to increase power and to avoid running rich, which this car naturally does and to avoid misfires from a rich condition.

1 gallon of e85 has 65% of the energy 1 gallon of gasoline has. So the car needs to compensate for the other 35% by adding more fuel which means different tuning based on % of ethanol, upgraded fuel pumps and injectors.
Literally in the manual it says do NOT use ethanol. I don't know how much more clear it can get.

*sigh*
Your math is off but it doesn't distract from the point you are trying to make. However, 65% more energy is not 65% more flow.

We don’t need an upgraded fuel pump or injectors to run flex fuel. Once again, without CPI, very few people are running pure e85. Most are running about e30, which does not max the injectors or the fuel pump. People blending their fuel are likely using a tuner to adjust for it, which is not limited to just the JB4.

The manual doesn’t say not to use ethanol. That would be effectively eliminating the vast majority of fuel in the states.

You’re really in a thread about tuning talking about what the manual says? C’mon man.

Seriously though, we’ve been there and done that. A few times a year someone comes in and rails about using flex fuel.

I never said it needed 55% more flow I said It needs to compensate for that missing power.
It is around 34% more E but were not doing the math.
The tuners the stinger uses isn't even a flex fuel tune with a flex fuel sensor IE: subarus running a cobb FLEX FUEL KIT. You don't just put 30% Ethanol in a car and say yeah the ecu will compensate with no way of actually reading what is going into the tank.
I'm not "railing" on flex fuel but using it in the stinger with no real tune or hardware to run a real ethanol set up is silly.

65% + 55% = 120%. Your math is flawed. You mentioned energy and you erroneously equated an increase in energy to somehow max out the Stinger’s stock components.

You’re incorrect about tuning. There are flex fuel sensors that can be added to the Stinger. I, and several others, have one and they use a 1-5v signal to integrate with the JB4 and other tuners.

It doesn’t have to be your “fancy”. Just because it isn’t your “fancy” doesn’t mean anything is wrong with it, that it shouldn’t be done, or that it isn’t safe.

Extensive testing has been done with it and it’s perfectly safe and fine for use in this car. If you don’t like it and want to refute a few years worth of results showing that it’s fine, have at it.

That's not a flex fuel tune it's simply a reader. Obviously you have no idea what it actually takes to make an ethanol based flex fuel tune.

It is not possible because I bought the speed limiter delete version the pro tunner cables are connected to the governor and speed sensor and if I remove it it will not work But I'm not sure

Man, you have to be trolling now.
First, you said 65% + 55% = 100%
Second, you said JB4’s fuel wires are for e85.
Third, you said the Stinger cannot use ethanol at all and that it’s in the manual.
Fourth, you’re in a tuning thread complaining about tuning.
Then you said the tune for the stinger aren’t using e85 with a flex fuel sensor.

In all scenarios you’ve been wrong but you keep going.

And you’re still wrong. The flex fuel sensors for the Stinger provide a scaled 1-5v output that sends a signal to the tuner for the ethanol content and the tuner adjusts the map accordingly. When there’s no ethanol, or no methanol, the map adjusts to a premium pump gas map. This is a flex fuel tune.

Despite the world around us, it’s still ok to say you’re wrong.

It looks like you cut a wire and sent it to separate wires on the lap 3. If that’s the case, just reconnect the cut wire.

 

[Stingerr]

I already tried and the check engine light comes out and the meter doesn't work
