Evo X Logging

Do you have the complete code in lb/min to include this in Evoscan mode 23? This is for the USDM models.
Thanks
PS: I want to thank you both for mode23 logging. It works like a charm. I have stopped using my beloved PCMScan to tune Evo Xs

Evo4mad PLEASE fix the LM-1 wideband glitch in Evoscan ver 2.5/2.6. Everytime I lift off the gas for an extended period of time the LM-1 logging via Evoscan stops and never comes back. I have to re-start the log to get it to work again. I have told you about this a long time ago. I am currently logging with ZT2 and I prefer to log with the LM-1.

The conversion from g/s to lb/min is 0.1323, so just multiply by that in the formula. Or to simplify, just use x * 0.002646 to get airflow in lb/min. I'd be very curious to see how much airflow you are logging just to double check it's the right formula.

For example the formula for timing is this
<DataListItem DataLog="N" Color="" Display="Mode23 TimingAdv" LogReference="Mode23TimingAdv" RequestID="23808a07" Eval="x-20" Unit="deg" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-15" GaugeMax="50" ChartMin="-15" ChartMax="50" ScalingFactor="1" Notes="" Priority="1" Visible="False" />
What would the formula for airflow in lb/min be?
Thanks

MUT initialization in CT9A returns 4 bytes:
0x00 0x55 0xEF 0x85
MUT init reply bytes' locations in 53040010:
0000E300 ECHO_REPLY 0x00 - presumably
00040F84 Sync word 0x55
00040FC4 KeyWord #1 0xEF
00041034 KeyWord #2 0x85
so whole trick to get MUT communication is hidden in this code
Now who will be the first to sort/try it out?
I bet on tephra, but hamish is my second candidate

Do you have the FULL code that needs to be entered in the xml file? I do not know what to put in the xml file.
For example the formula for timing is this
<DataListItem DataLog="N" Color="" Display="Mode23 TimingAdv" LogReference="Mode23TimingAdv" RequestID="23808a07" Eval="x-20" Unit="deg" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-15" GaugeMax="50" ChartMin="-15" ChartMax="50" ScalingFactor="1" Notes="" Priority="1" Visible="False" />
What would the formula for airflow in lb/min be?
Thanks

Here ya go...let me know how this works:

I do not know what edge detection is used raising/falling or both?
Presuming that changing counter is what the name is saying and only one side edge detection,
one has to send 0xAA 0xAA 0xAA 0xAA 0xAA, in order to get to the last line of above code.
So init reply shall look like 0xAA 0x55 0xEF 0x85.
What line is pin83 actually OBD PIN 7 or OBD PIN 8?
Unfortunately I do not have the ECU to play with, it is based only on disassy.

If I would have the ECU, I would write application that is sending init codes 0xYY running from 00-FF, and observe the reply,
once I would get 0xYY 0x55 0xEF 0x85 reply that would be the init code.
Btw. I know we have the solution already, but I am trying to find the clean solution, working without Mode23 patch.

Tephra, you know we are so close, it is only one step to get it working,
I have been looking at the MUT code, it is exactly same just built for different processor.
Have you found variable that holds the L-line, reflash,
does it appear in that init routine?

I don't think its "L-Line"
If you trace back the mode23 stuff you will see it requires OBD-Debug (Mode0x10) to be set first.
AND then ontop it requires something else to be set, this can be traced back to a I/O pin - I think its in my disasm I sent you...
Trouble is I can't set a voltage on OBD PIN8 (the only other pin hooked to the ECU) because OBD Pin8 isn't a valid choice in J2345... weird!
