Just trying to log them and can't figure out why they won't when they are flagged to log. Just getting 0's. I searched the forums and no answer...do any parameters have to be set differently than they come from an install?

 

I believe only speed and rpm are required.

 

i think you need 2byte airflow, and 2byte load to view those parameters..im not so sure because it doesnt work on my EvoScan as well..

 

nope, mine worked even before I ever did those mods.

 

did you, by any chance, re-ordered the sequence of the log items in the XML definition file?
It's using some other log items to do the calculation so those items need to be log first. It's logging those items but if any number multiply 0 is 0.

 

What rom do you have? Mine logs HP and Torque. I had to set it up for 2byte air and load. I have 88590015. I can get you what you need.

 

I have that same rom and mine doesn't work Drivin...

What do you have that makes it work?

 

2 byte Load

2 byte air

The thread above also has the info for hp and toque for EvoScan.

 

This is what I get when I log.

 

What do you need for 2 byte to work? Just add the tables you posted?

 

I updated my post above with all the info.

 

The evoscan estimated whp and torque are set as below. You see that 2-byte load is needed first in order for the rest of the evaluation to work. Just make sure 2-byte load works correctly and places before the items below. The settings file named Data.xml and reside in the EvoScan DataSettings directory. You can change it using Notepad.

<DataListItem DataLog="Y" Color="" Display="Estimated g/rev" LogReference="gRev" RequestID="00" Eval="[LoadMUT2Byte]/95" ... /><br/>
<DataListItem DataLog="Y" Color="" Display="Estimated Lbs/min" LogReference="LbsMin" RequestID="00" Eval="([gRev]*[rpm])/454" Unit="lbs" .../><br/>
<DataListItem DataLog="Y" Color="" Display="Estimated Horsepower" LogReference="WHP" RequestID="00" Eval="[LbsMin]*9.15" Unit="Whp" .../><br/>
<DataListItem DataLog="Y" Color="" Display="Estimated Torque" LogReference="Lbsft" RequestID="00" Eval="([WHP]*5252/[rpm])" Unit="lbsft" .../>

 

Ahhh, I did change all the ordering. Thanks for the info!! I will give that a go

 

Yes, first you need 2-byte load, then you also have to log g/rev and lb/min to get the HP/TQ calculations.

 

Has anyone validated the accuracy the HP equations?
