How do you add the two in an expression properly?

I meant what would the formula be to use for evoscan or ecuedit to output the data already added together.

Its easy in Mitsulogger.. its basically identical to what he posted, where you only change the name of requestid00 and requestid01 to represent the labels you gave it earlier in the XML file.. ECUEdit may not be capable of doing it, but Evoscan should also be able to do it.
Mitsulogger can use that formula without alteration...

Code:

<Request LogReference="requestID00" RequestID="00" Eval="x" Unit="INT" Logged="y" Response="2"/>
<Request LogReference="requestID01" RequestID="01" Eval="x" Unit="INT" Logged="y" Response="2"/>
 
<Request LogReference="Load" RequestID="FF" Eval="((256*requestID00)+requestID01)*10/32" Unit="2byteLoad" Logged="y" Response="2"/>

as you can see, you can add the first two lines to the section with the regular requestIDs, the Load can replace the custom FF requests.. (I'd just leave the original and set it to Logged="n" by default)

Out of curiosity, since I don't have this info.. But what are the original purpose of requestID00 and requestID01

When I log the data without the mod it definitely shows information...

In my 94170008 ROM:

Code:

ROM Address   Request ID   Original UINT16
&H38062       01           34959
&H38066       02           34958

Are the values stored in a continuous block? Would Request ID 03 be &H3806A?

Thanks again. :-)

Nah, I looked up the table, Although every one points to an area of ram, there not really contiguous.. You kinda have to trace the memory location its using to a subroutine, then identify what the subroutine does to figure it out.. Not something I have the time for unfortunately.

The original requestID 00 and 01 seem not to be defined so far. They are related to others that appear to be a lots of flags.

yeah the original requestID 00 and 01 are just some silly flags for some relays, and other items.. not even worth logging

Thats what I thought.. I set it up to break them out to bits, Not sure what bits they are, I think injector, ignition, and a few others solenoid and relay stats..

I'd like to know for sure what every single requestID is and what it does before I "discard" any of them though.

ecuEdit do this simply - just set storage type to "uint16":

Code:

<parameter id="Engine Load (2bytes)" offset="#00" storagetype="uint16" reverse_bytes="True" decimals="2" expr="[value]*10/32" metric="%" desc=""/>

Each requestID still needs to be queried individually.. The one Bez is working on will return 2 bytes (a uint16 value) Not sure if what you posted for ecuEdit is doing that but if it does then at least everyone knows for sure its capable..

The way my app is doing it is requesting the raw data from each, and then assembling/calculating it afterwards..

I have been testing with this for a little while. The results look promising. At idle, the 2 byte load matches the ECULoad requestID 1C.

I have not had any time to go do some road dyno runs. I should be albe to do that tomorrow
