how accurate is this thing? the reviews dont sound very good.

 

[EMS/T]

looking for the charge air temp. Went through the thread must have missed it. Can some post it up for me??

PID: 220461

Formula: ((((signed(A)*256)+B)/64)*1.8)+32

@xxx I updated the formula as per Stratified.

Thank you!!!

PID: 220461

Forumula: ((((256*a)+b)*.011404134)+9.26087)*1.8+32

How accurate is this equation. Mine seems a little high. I'm running around at 19* above ambient which for a steeda fmic seems pretty off

Seems pretty close to me. I got the formula from following the link in this post.

My intake temp gauge seems a few degrees hotter than what the "ambient" on my dash reports. My charge air is usually pretty close to the intake air temps.

This is a screenshot of Torque from the following morning after I installed Depo Jr in to my car. Ambient was probably high 70's to low 80's with low humidity.

EMS/T do you need a PID for that boost. I have not found boost, at least one that seems to work.

TIA

I mentioned it in a few pages back but I used the one built in to torque that's called "Turbo boost and vacuum". I tried others and formulas until I stumbled upon the built in one.

You will have to zero out the dial in your "vehicle profile setting". Turn the car on but do not start it, to see what the value reads in the gauge. Then go to your vehicle profile settings and you will need to plug in the value that would zero out your gauge. Start the car and you should be in negative numbers until boost hits.

that frustrates me a tad... either something is off with my car or my FMIC is hovering at 20* over rather than the 10* over everyone else seems to see.

Thank you, it works great!

I didn't get a chance to finish testing everything last night, but I believe the equation for it according to the ECU would be:
((signed(A)*256)+B)/64

Usually when you see one of those complicated equations, its because someone was trying to fit it by hand, and it isn't directly from the ECU.
It'll probably be off like what you're seeing. Try that equation and let me know. It should be reported in degrees Fahrenheit. (Though I haven't checked yet, it could very well be Celsius)

just added the new equation to a second charge air temp gauge for comparison. I gotta finish building this laptop here at work then i'll run out and try it.

This is my layout that I have been messing around with.

How did you make your displays look like this? Those look great! I went through this whole thread, did not see anything and been playing with the app, not seeing it.

TIA

Found it..............THEMES!!!!!!!!!!!!!

Thank you for posting that! I got mine from somewhere else but I'll try that out shortly.

It would be nice to put together a nice list of all the correct values and sticky it. Seems to be a lot of misinformation floating around during my searching.

As soon as I get a chance to verify them all I can get my csv posted up.
They're basically a direct steal of the DID listing from the ECU source.

Also any you see that start "22F4" are just the direct access to OBDII PIDs, but they are usually updated at a much faster rate than the normal OBDII PID one.
The equations for those are mandated by the OBDII standard. And you can get them directly from the standard (there is a list at Wikipedia: https://en.wikipedia.org/wiki/OBD-II_PIDs)

I.e.
22F43C "Catalyst Temperature Bank 1, Sensor 1"
Equation would be:
((A*256)+B)/10 - 40

In Celsius. You can then convert it to whatever units you desire from there

The only one at this point that I cannot seem to get to work or find, is Oil Temperature. Do we have the ability to monitor this one?

It is not a supported OBDII PID, and it's not a Ford DID either from what I've done yet. On the one strategy I've been working over, I have found the internal Engine Oil Temperature memory address, but I have not yet traced it to any of the available DIDs. It's possible it could still be one, as a lot of times the DIDs are sampled at an occasional rate, and I just haven't found the sampling for Oil Temperature yet. This happens for a few I've noticed (like low pressure fuel pressure for example).

At this point, it may only be available as a DMR (Direct Memory Read), which will make it engine strategy specific. In the long run, DMR is pretty much the fastest route to pull data if it isn't broadcast over the CAN Bus and can be listened for (of which Torque is unavailable to do anyways). I don't even know if Torque is capable of performing a DMR at this point. That may be something that is simply not in its capabilities.

Thank you for the info! I'll start reading in to that Wiki.

I took your formula for charge air and added it to Torque as Charge Air 2 or CA2 as the short name. It came up in Celsius so I multiplied it by 1.8 and added 32 (New Formula = ((((signed(A)*256)+B)/64)*1.8)+32 ). It's within 1-3 degrees of the formula I had originally posted.

@VenomousSVT Here is a screenshot with @Bugasu@Stratified 's formula. It came in as Celsius so I revised it to convert to Fahrenheit.

 

[Bugasu]

Well my formula is straight from the ECU, so I know it's right Thanks for figuring out the units
The old charge air temperature formula is not signed, and as such it also won't work well if your outside temp dips below 0*C (32*F). Not that many people will see that happen, but I know I do on a regular enough basis.

Good to know!

Where I'm at, I'll never see snow unless I ship the car to the Big Island and drive to the top of Mauna Kea. lol, that ain't happening anytime in the near future! I'm barely at or above sea level, depending where I'm at during the day.
