I cannot seem to figure out how to activate these pid's?.

Thanks in advance

The 07 hemi and up logs have them or you can make your own custom logs. You select what PIDs you want to view with dataviewer.
Always a good idea to view them in graphical form and always have your engine speed (RPM), throttle Pos sensor selected so you can see what RPM things are happening at and make sure your not getting any throttle closing at shift and I always view the actual spark Cyl # 1 to see if any ST KNK is pulling actual timing..

Here is a shot of how to select the PIDs. When at the track, I have engine RPM, ST & LT KNK and actual spark and A/F (from a wideband) all on the same page so I can view it with the trinity and not have use the laptop. Moving the up and down arrows on the trinity will let you view other parameters in playback mode.

KJ, is it recommended that you do one long log at different speeds or divide it up?

So you do this via laptop or in the car?, I am assuming with the tuner connected to the laptop using data viewer?
do I need to log a run first? or can I activate those selected pid's first

Thanks

I'm not data logging to get a custom tune, I'm data logging my race tune to ensure I'm safe at he track (not too rich with the meth or ST KNKs).
All my logs are WOT but you are correct if your data logging to mail to a tuner, you need open and closed loop data.

Do the run and then select the PIDs you are interested in. Again the 07 hemi and up has just about them all so you just check the ones you want to view after you have uploaded your log.
At the track, I playback my run logs via the trinity and ensure my A/Fs are good and I'm not getting any KNK. Don't want the laptop weight or it bouncing around at the track When I get home, I download them into my PC and use dataviewer to further analyze my intake temp, launch RPM and other stuff.
For me, I set up a log page with ST KNK, LT KNK, RPM, and A/F from my wb all on one page so when in playback mode I can see when stuff is happening (low, mid or high). Dataviewer will let you view them in gauge or graph form. I prefer graph where I can overlap the various PIDs over my RPM plus it has a real time clock on the bottom so I can see how long a ST KNK may last etc.
I think there are sample logs in dataviewer that you can play with and pick various PIDs to get a feel for them. Go into dataviewer and hit file, open log and mine defaults to the sample logs so yours should too.

Sample Logs

Here is a screenshot of the sample Logs that come with dataviewer.

I run the main pid also at the track, ahh hell anytime really. But I have one I use on track day being I have a/f on the dash in gauge form also logging to trinity. I also select the BIG screen with on main pid that is
ST kr I have on one full page. So I scroll to that one and leave it up to monitor or be able to glance at and you can see the timing kr and abort the pass if you pull say 5 or 8 deg of kr;
I like that big single gauge to have as saftey to look at on a pass.

I think there may be a little confusion as to what you mean by active, maybe it's just me. Are you asking how to show the PCM data of those PID's? If so, if they are on the screen, like your pictures show, they are activated and you should see the data when plugged in to the OBD port.
If you want to log, you can just go to create log in the tuner, select the gauge layout you want and record. You can then download it from the tuner and watch it on the data viewer, slowing it, fast forwarding, pausing and making notes.

What I am saying is while driving I see no changes on the screen of those parameters. those specific parameters I have listed stay @ zero.

Okay, that helps.
Use a preset gauge layout on the Trinity, or make your own. I made one with 4 pages of specific PID'S I wanted. Mount the Trinity in the car (wow, that could be interpreted another way), plug in the DS provided OBD II cable to the Trinity and OBD port. Go to the bottom, center icon to open and monitor gauges, not create and record a data log. The gauges do not have to be activated. If they are on an open layout, you can monitor it.
If the Trinity pics you posted are of your tool, it looks like it is working, you had 1* st knock at some point. On that top page, throttle position is really all you need. The two you really need to watch is the st and LT knock. If you think it's not working because it stays at 0, that's excellent, that's where you want it.
Most of those PID'S had activity, look at the bottom of each gauge.

I have also noticed that the injector pulse width is not reading

I think I am getting somewhere. it appears that to get some of these to work you have to set minimum and maximum values? does this sound right?

That I don't know. All the PID'S I use don't require it. Just curious, and I'm a firm believer in monitoring, but do you have a specific goal/purpose for monitoring? Wondering why you are wanting to watch injector pulse width and throttle v.

On a Trinity with the factory PIDs (ie. 07 hemi and up) you don't have set set anything. Only time you have to set parameters are to calibrate an external device like a wide band in one of the two analog inputs.
Easy to make a custom layout. Have RPM, ST KNK, LT KNK and one other of your choice on one page with large readouts so you can see what is going on while you drive (monitor instead of log). I include the throttle Pos Sensor Percent so I know when I'm at WOT. Logs are to analyze on a laptop or playback to make tune changes. Monitor to see what is going on while your driving around. You can log your driving around stuff but it is a lot of data and it gets confusing as weird stuff hapeens when you decelerate and then accelerate. Only analyze WOT if you plan on making changes as that is the only time the changes take effect. If you see partial throttle KNK, your only recourse is to got to a lesser octane tune or increase your octane,
Use the 07 hemi and up layout when you log. It will give you everything you could ever need to review with the exception of A/F in which case you need a wide band.
If you don't think your ST & LT KNK are reading, put her in a high gear and bog the piss out of it. They will register. Don't tune to it in those conditions but just do it to set your mind to ease that they are working.

I just wanna see if I get any KR with the gas I've been putting in exclusively from my local chevron for the last two plus years.

Okay, I'm assuming the pics you posted are recent. Your short term knock gauge is working. It registered 1.00* of retard when you were driving, probably a short spike and you just didn't see it.

Personally, I like ST and LT knock, RPM and open loop FA gauges on one page. I have intake air and coolant gauges, throttle %, and speed on others.

So it appears that you had a ST KNK. IMO now would be the time to do a log (07 hemi and up). Run for 30 seconds or so with some WOT bursts (not bogging in too high of a gear). Then you can save the log (you'll have to name it so I use A, B, C etc).


Plug the tuner into your laptop and play back the log using dataviewer. Select the PIDs you want to see (ST KNK, LT KNK, throttle Pos Sensor% and RPM). I view them in graph form so everything overlays in real time.


Here is an 1/8th mile WOT run. Purple is Throttle Position Sensor %, Green is RPM and yellow is ST KNK.


As you can see, I get a .5 ST KNK @ 5200 RPM and then it goes to a 1.0 ST KNK at 5375 RPM in 3rd gear only.


The logical fix would be to pull one degree of timing up top (5K - 7K) and that should remedy the ST KNK. I hate to do this because it penalizes me in 1st and 2nd gear. It would be great if we could adjust fuel and timing in each gear in which case I would leave it alone in 1st & 2nd and pull a degree in 3rd.


This is a 91 octane canned tune and as you can see, there is still tq mgmnt in play as my throttle burped at shift. You generally want no dip in the throttle and only 7 degrees of timing pulled at shift. This was with Shell 93. I have better luck with Chevron in the Austin area.
