Accessport V3 parameter monitoring

So some people, including myself, were curious on what some good things to monitor on an AP would be.

I currently monitor boost, HPFP pressure, knock, IDCs, LTFTs, and WGDC/whatever I feel like looking at. More so I switch the last one around depending on what I'm doing.

What do you guys think? What are good things to monitor and some limits/numbers I should be worried about if I see them during a pull? What should I monitor if I'm logging?

Just curious to see some differing ideas!
 
Right now I have Boost, AFR, Coolant temp, LTFT, KR and Boost Air Temp.

Boost = It's nice to see that my pad thai pounder is making 35 PSI. I def like to swing that big dick PSI energy around. But on one occasion, I saw it spiked to 36psi when I know my tune was commanding 17psi. Checked the line to EWG and sure enough, the line came off.

I have coolant temp on screen to make sure I don't reach too high of a temp. I see 220°F on average. I feel that once it gets to 225 and above is when I need to see if I have a leak somewhere or maybe the system is not bled properly.

LTFT is to check if I have some vacuum or boost leak. I've heard people say ~10/-10 is still okay. someone can definitely chime in.

KR just so I know that my pistons aren't knock-knocking on heaven's door.

BAT I've never really paid attention to honestly.
 
I use Versatune and keep torque on my phone for just casual pid viewing. These are the values I use. GPS speed because my summer tires make the speedo wrong. I use "Kitbest Bluetooth OBD2 Scanner" for my obd2 scanner and it works well. I don't log with this I just use it to see while I am putting around as peace of mind. You will also need the mazdaspeed torque pid addon from the play store.

Is this thing worth a damn? Pretty accurate readings? In a timely manner?

This is what I monitor, haven’t changed it up at all yet unless diagnosing or something.

I feel like that’s all you really need. I’ve recently installed an oil temp/pressure gauge and an afr wideband failsafe(thanks to @_Mazdarati for that one) but that’s more for the track usage my car sees. Regular street usage, oil temp/pressure probably aren’t necessary. Since AP shows max/min values you’d have to either log, or watch the AP while logging to find any real issues, and typically you’ll feel a real issue(during a pull) before you think of looking at the AP.

Totally worth it. It's not crazy fast but you can see if shit's getting bad or if LTFT starts to creep. It can also pull check engine codes and clear them. Mine auto connects when I get in the car and I have this "Amoner Dashboard Car" to hold it like an AP.

Was just wondering, I have a AP coming in, but V2.
And if you know a v2, only shows one gauge. So this would be nice to have if accurate enough reading are available.

Looks like back in my Mazda days I watched the following -
* AFR - handy to know how your tune/engine health is/are there any leaks
* Boost - obviously if you aren't hitting crazy numbers, you need to drive harder
* Coolant temp - didn't move the car until it was up to like 180*
* KR - never really looked at this since KR only matters at WOT
* RPM - dash gauge gets real inaccurate above 7,200 or so
* LTFT - check for leaky leaks

BAT- Dont like beating on the car when bats are high
Rpm- tach is inaccurate at high rpm
Boost- no explanation needed
KR- impossible to watch during a pull, but oh well lol.
Afr- to make sure port injection is spraying when it's supposed to
Coolant temp- no driving til 138* , no boost below 180*. And watch for any possible over heating issues.

I also logged almost every WOT run or spirited drive I ever did thru the back roads, to have data to review in case anything ever catastrophic happened and I wanted to find out why
 
I'm using a poverty 2 so usually
AFR - Check PI functioning
Knock- Watch my cars life flash before my eyes
 
No, there are no PIDs available for those parameters. You have to install dedicated gauges for oil temp/pressure, usually utilizing a sandwich plate on the oil filter housing.
