Torque (Android app) AFR for the RX8?
 

Hi,

Do any of you know how to add the AFR dial to the "Torque" Android app?

The program allow you to add custom PIDs adding the hex code, minimum and maximum values, scale factor and equation, but I've no idea what would be the values for the AFR for the RX8 (googled it but could not find anything).

Thanks.

AFR values are pretty much the same for all cars, you can just put 0 to 30 or so to have a decent scale on it.

It will be about 13-14 for cruise, 11 for pedal to the metal and 20+ for foot off gas.

Yes, but I need the hexadecimal PID code and the formula multiplying the ECU provided voltage to get the final value.

Found it!

I'm pasting them here too, for convenience:

PIDS that work out of the box with Torque:
Load
Fuel Level
RPM
Intake Temp
Intake manifold pressure(in kPa)
Coolant Temp
Vacuum/Boost Gauge
Barometric Pressure
Mass air flow rate(in g/s not voltage)
Throttle Position
Timing Advance(Works, at WOT shows near 0 degrees. Yay stock tune!)

Enhanced PIDs you have to manually enter
Long name & short name can be whatever you want. I tried to stick to conventional names.

Cool, thanks

Agreed now people don't have to get accessport if they just want to reset CEL. Good find, I didn't even know about this.

There are dozens of simple obdii scanners that can clean the CELs...

Well theirs a lot of people that come on here wondering what they can do to clear CELs. The only replys they get is accessport. Access port is a great thing to have but if your just looking for a way too keep your CEL off this is it also the other attributes the app has.

fyi, the 8 does not have a way to measure fuel pressure. Just tested all the other PID's and they're working fine with Torque

nice to see AFR's without having to plug in my access port.

how does this work with out a cable? I know there is probably an OBDII port but just woundering if there is a cable out there, i have the Droid2 so hey a $4 app + cable sure beats standalone to check things lol

bluetooth dongle plugs into your obdii port.. phone reads that through bt naturally :)

wicked.... no more getting the usb cord tangled under the leg, or threw the e-brake handle or just forgetting to unplug it from the OBD port and droping your laptop..... :wallbash:

I was thinking on leaving the OBDII bluetooth dongle always connected, but I've noticed that the car always provide energy even if the contact is off and I fear to drain the battery; the dongle I have ("PLX Kiwi") doesn't seem to auto turn off (I waited for 10 minutes).

I have the kiwi dongle and just turn off the switch on it when i get out of the car.

The difference between clearing and hiding a CEL is great. As far as I can tell Torque can only clear the CEL, not mask/hide it.

I have obd2 cabel bt i don't have the tune softwear can any one give me the link or name of the software where i can tunemy rx8....

I have the Kiwi BT dongle and I leave it connected 24/7 and don't turn it off. Its been that way for 6 months now and my battery's fine.

Also, its true that these adapters will only clear the CEL until you turn the car off and back on again.

I've had the ODB+Key as the dongle for a while now, though I use it more on my other cars than the 8 (since I also have the AP). I've found that it doesn't like the 8 all that much. Plugging in the dongle and opening the app disables my TCS/DSC. Have to disconnect and remove the dongle and power off the car before it will recognize it again.

Anyone else seen this? No issues at all on my Mazda5 or my Miata.

Just started using mine yesterday, and my TCS/DSC are working fine.

It looks like one of the most recent updates brought A/FR support natively to Torque.

[QUOTE=Also, its true that these adapters will only clear the CEL until you turn the car off and back on again.[/QUOTE]

I use the Torque app, with a BT android phone, when i clear the CEL it actually goes away until the problem occurs once more. For eg: I had a P2405 code, cleared it but came back on a week later, cleared again, came back on a around 3 days after that..Unless someone has a serious problem that the CEL won't clear

Sorry to thread revive but I figured this would be a good place to ask since the custom PIDs are listed.

Is there any way to get an oil pressure gauge on Torque? The one that comes with the program doesn't read.

there is no oil pressure reading on the canbus so no you cannot.

dashcommand recognizes all the mazda pids out of the box and has a better skin than torque imho

How many more does it recognize? I don't see a few pids and a better skin being worth $35.

As stated, "out of the box" it detects the mazda specific pids without any hassle. If you rebuild your android with any frequency remotely close to me, you'll quickly grow tired of having to always recreate the profile. Tools like Titanium Backup are good -- but only when you remember to use them and don't save you under all situations

if $$$ drove all my decisions I certainly wouldn't own a rotary. By looking over Juan's list (I'm series 1) I'm not sure if fuel pressure is present. I have the Windows Parmer software w/ Mazda expansion and don't believe its listed -- could be wrong though.

The only one I recognize not listed above is the Open/Closed loop indicator ... although you may be able to derive it from the Open Loop AFR pid.

The skin editor is pretty neat too. You can re-arrange, or completely rebuild the skin as you wish. I've pulled things out that we can't track such as boost and fuel pressure and have consolidated a couple of the panels -- and flat out removed others such as all the silly fuel consumption stuff.

I still do fire up torque... don't get me wrong, but the dash command stuff is a bit more fancy. It manages CELs a bit more intuitively than torque too and its built in CEL database is bit more comprehensive than the torque one -- even when you use torque's "web" search.

Remember, I typed "IMHO" :)

Understood, Torque also has open loop/closed loop built in and reads it without having to enter in a PID. His list was the one's you have to manually type in and the FP doesn't work.

yup ... i guess for me the $35 dollars (amounts to nothing compared to what I paid for the Windows software) for DC is reasonable for not having to deal with recreating profiles and having a bit more flexibility in skin design -- although torque's WYSIWYG interface is far from bad itself.

Torque will now also mask the CEL - Go to Settings / Speech and alarms / Select Periodically check for faults / & enable Automatically clear faults (Only been released in the last month)

Doesn't clearing a CEL also reset things like STFT and LTFT?

Don't know - I would be surprised if it did - I'm using to clear the CAT and the fact that I'm using D585 coils - Will have to test it to see as I dont currently monitor these ...

Teh only way from what I've read to clear the STFT & LTFT is to do the following (Unless you have a Cobb I guess) - I found this in another post

NVRAM (Non Volatile Random Access Memory)
NVRAM is a rather unique feature. The system memorizes the profile of the eccentric shaft plate on the e-shaft pulley. It basically knows how the e-shaft spins, on an individual basis, 2 cars NVRAM will generally never be absolutely identical, they’re pretty close to unique.

As you’d imagine with such a specialized system you wouldn’t want this information relearned and forgotten very easily, relearning the profile isn’t a short process (drive cycle, dont worry you dont do anything special to relearn it). So this info is kept in a special area of the PCM it CANNOT be cleared in any way EXCEPT the proper procedure, you could disconnect the battery and do a jig for a year and it won’t erase.

When/Why should you erase the NVRAM?
Realistically there are only a few times, generally the only times it’s really needed is when replacing a motor since you’ll be installing a new e-shaft position plate. Sometimes you’ll also repair a misfire, yet the misfire code will return even with you not noticing anything, in those cases clearing the NVRAM will sometimes help. Also during PCM replacement it’s good to clear it.

How do you reset NVRAM?
Here it is straight from mazda:

NOTE:2004-2008 and 2009 and later model year procedures are different.

2004-2008 Method

1. Turn ignition switch to “ON” position, but do not start engine.
2. Pump the brake pedal at least 20 times within 8 seconds after the ignition switch is turned ON.

NOTE:
Manual transmission equipped vehicles produced after VIN 40132647 and automatic transmission equipped vehicles produced after VIN 40132607 or vehicles with PCM updated to “L” calibration or later can confirm the clearing procedure was performed. If procedure was successful, the oil pressure gauge needle will move to right of center slightly (nearer H).
Vehicles produced prior to these VIN’s or vehicles without “L” calibration do not have an indicator to confirm the clearing procedure was performed.

3. Drive vehicle and confirm misfire related DTCs are not stored.

NOTE:
If the malfunction cannot be corrected even though the procedure was successful, the eccentric shaft position plate may be damaged. Inspect the eccentric shaft position plate. Refer to MS3 online instructions or Workshop Manual section 01-40 ECCENTRIC SHAFT POSITION PLATE INSPECTION and repair as necessary.

2009-2010 Method

1. Record customer radio station presets (FM1/2, AM, SAT).
2. Disconnect negative battery cable for a minimum of 1 minute.
With negative battery cable disconnected, depress and release brake pedal one time.
3. Reconnect negative battery cable.
4. If equipped with DSC, perform the STEERING ANGLE SENSOR INITIALIZATION PROCEDURE located in MS3 online instructions or Workshop Manual section 04-15.
5. Input customer radio station presets.
6. Initialize power windows. Refer to MS3 online instructions or Workshop Manual section 09-12 POWER WINDOW INITIALIZATION PROCEDURE.

KAM (Keep Alive Memory)
Keep alive memory is not named because it keeps the car alive, rather it’s named after the way it works. When you remove the battery terminals from the battery you’d assume all power in the car is lost right, hell your clock resets so the PCM must too, right? WRONG. KAM is saved by “Keep Alive” power, reserve battery power if you will.

KAM generally doesn’t store very important stuff, other then the airbag operating on KA power they dont store anything in the KAM tho they just use the same reserve power. The main thing KAM stores are things like fuel trims etc. It’s useful to reset KAM when you have lean/rich codes where the fuel trims have been able to reach 25%. It takes a while even after repair for the fuel trims to go back to proper levels, if you clear the KAM it will reset them to 0%.

How do you reset KAM?
Two easy ways, disconnect the battery and leave it like that for at least 10 minutes, sometimes longer. To expedite the process disconnect the battery and hold down the brake pedal, itll drain the KA power quicker. This will allow all codes to clear and KAM to clear.

After some research, at this time, it seems pulling the Room Fuse on the interior fusebox will also clear only the KAM. Not 100% sure yet, but pretty close

It's easy to check,
Wait till your car builds some LTFT at idle, as it surely will if its stock or even slightly modified.

Reset the cel ... lets pretend for the catalytic (because you have a race pipe).

Check to see if the LTFT is back to 0

Guys is there a way to display the oil temp with any of these apps?

Not unless the oil temp is read by the PCM which I don't believe it is.

For all you Torque users...Do you guys know what the difference is between "Fuel Trim Bank 1 Long Term" and "Fuel Trim Bank 1 sensor 2"?

Hi sweetfa,

I am running catless and have the 02 cell. I see you said the newest update will mask the cell. My question is do I have to leave the torque app plugged in to mask this? Or can I just upload Torque once, mask the cel, and walk away. Will the O2 cell stay masked?

Torque needs to be running to clear this each time ..I'm running a gutted cat and don't get a cel for it all ? - I did have to replace the rear o2 sensor though. I run D585 coils so I get a CEL for those

i am very freakin curious how does torque read vacuum and boost as the rx8 does not have a map sensor.....

It doesn't ... there is no MAP PID on our car.

The list of PIDs a few posts up is what Torque looks for. It can only display what the ECU transmits still.

im mine,torque does see boost and vacuum:)))))i will put up a video for all who dont belive it:)

How does it see boost?

I'm thinking of trying this all out with my Galaxy Nexus to see what all the hoopla is about.

(just another app that will ruin more of the battery life)

check this out!i dont now how is this possible:)))

torque app rx8 - YouTube

The vacuum data is clearly reported by the ECU, which means there is a sensor somewhere that picks it up. I can point to my 99 Miata's vacuum sensor. Even though the engine is MAF based, it also has a vacuum sensor.

The 8 is probably the same.

It might not even be a strict vacuum sensor, but part of a different sensor that figures it out.

Torque can't report anything the ECU doesn't send (except for the other items based on the device's data like GPS, motion, etc...)

i was looking everywhere but still did not find a map sensor on the 8...but still the torque can see vacuum and boost readings on it,i have tested and compared the numbers with the boost controller readings and when the boost controler shows 0.53 bars,the torque shows 0.6.now witch one is correct only god nows.....i will stick with the boost controller as i do not trust torque for boost readings

Yeah, it's likely that the sensor is calibrated for vacuum, not for boost, and it gets inaccurate in positive numbers.

Then there is torque's read delay, etc... I wouldn't trust it for something you need instant info from.

Though I use Torque all the time for both of my cars. Have a tablet floor mount that I use to hold my tablet, and it's pretty much running if the car is. Still having ECU issues that I need to keep an eye on :)


Though Torque causes a DSC/TCS fault for some reason when it first connects to my 8. Have to shut off power and immediately restart to clear the fault and re-enable the DSC/TCS again. Not sure why that would happen.

It's an odd built-in vacuum PID, for sure. Does not line up in inHg with my boost gauge or Adaptronic MAP sensor (although they're plumbed to the same place).

At no load idle / neutral throttle up to 3000 RPM and it jumps to 8-9 positive PSI which is far from reality. The most my MAP sensor does is reach around -3 inHg still in vacuum -- no boost.

may be from your obd adapter,try another one.had this issue before with another adapter,now i am using a ELM 327 and everything is perfect

What is the difference between boost and vaccum? :P (which one is supposed to be the read out from MAP?)
