Hello!

I've been doing some logs with OP2.0 and RRLogger.
So far so good, but some standard parameters don't work.
I've been able to log Intake Cam Timing using these addresses:
Code:
<parameter id="P48" name="Int Tim B1" desc="P48-An incumbent VTC operation angle vVTCNOW_R#1" ecubyteindex="46" ecubit="3" target="1">
<address>0x221135</address>
<conversions>
<conversion units="°CA" expr="x*0.5-64" format="0.0" gauge_min="50" gauge_max="-5" gauge_step="5"/>
</conversions>
</parameter>
<parameter id="P49" name="Int Tim B2" desc="P49-An incumbent VTC operation angle vVTCNOW_R#2" ecubyteindex="52" ecubit="5" target="1">
<address>0x221163</address>
<conversions>
<conversion units="°CA" expr="x*0.5-64" format="0.0" gauge_min="50" gauge_max="-5" gauge_step="5"/>


But no luck with Exhaust Cam Timing. These don't work:
Code:
<parameter id="P83" name="Exh Tim B1" desc="P83-VTC operation angle (exhaust) vVTCNOWE_R#1" ecubyteindex="52" ecubit="4" target="1">
<address>0x221164</address>
<conversions>
<conversion units="°CA" expr="x*0.5-64" format="0.0" gauge_min="50" gauge_max="-5" gauge_step="5"/>
</conversions>
</parameter>
<parameter id="P84" name="Exh Tim B2" desc="P84-VTC operation angle (exhaust) vVTCNOWE_R#2" ecubyteindex="52" ecubit="3" target="1">
<address>0x221165</address>
<conversions>
<conversion units="°CA" expr="x*0.5-64" format="0.0" gauge_min="50" gauge_max="-5" gauge_step="5"/>


I've also had no luck with oil temperature at 0x22111F, though I believe the sensor is present on Rev-Up engine.

Any suggestions what addresses to try?
Of course Exhaust VTC is more of priority.

First swap these values ​​around
gauge_min="50" gauge_max="-5"

I've tried, didn't work.
I've seen that, but almost all the parameters under NCS protocol in all the logger definition files I've found seem to use that kind of "reverse" gauge, don't know why. Should be some reason behind that. Nevertheless most of them work fine.

But the problem is Exh Tim B1 and Exh Tim B2 are not even shown in parameters list when connected to ECU. So, I presume, ECU returns 0 values at ecubyteindex=52 bits 3 and 4, if my understanding is correct.

What happens if I swap ecubyteindex/ecubit from parameter that works?
Is there a possibility that this table is not 100% correct? https://www.romraider.com/index.php/RomRaider/Nissan#CapabilityBits

From my notes here CID1120 supmask, you'll need to activate 21 22 if temp is available and reflash

Thanks for your suggestion! It's not defined for my rom yet, but at least now I have a direction to look into

Update:
Was able to log a bunch of needed parameters without reflashing.
Swapped ecubyteindex/ecubit values from the parameter that worked (in my case used P4650 Vehicle Speed Ultra High Precision, but I believe any parameter that is available in RR logger after connecting to ECU could be used).
So basically I've edited the logger definitions file and specified
Code:
ecubyteindex="77" ecubit="6"
for all the parameters I needed.
Was able to log:
1) P122 Engine Oil Temperature
2) VTC target angle (exhaust)
3) VTC operation angle (exhaust)
4) Absolute throttle position
Data seems to be credible.

What do you guys think? Are there errors in the ecu capability bits table which was used for creating logger definitions or is it just the specific ECU?
