Formula on load calculation???

i was looking at my logs and i see that my load calculation is not quite right for what i read here by 7000rpms it drops to 167 load i see that the formula in evoscan has injector scaling at 513 and my injectors are scaled at 543 cause its a jdm version.
know how can i change this formula in evoscan?
and does it affect my knock sums or timing? or it wont matter?

thanks

Do you mean "Load Calculated"?

You should be able to change this by changing the following line in Data.xml (found in EvoScan\Data Settings folder):

Code:
<DataListItem DataLog="Y" Color="" Display="Load Calculated" LogReference="LoadCalc" RequestID="00" Eval="5*513*([InjPulseWidth]-(-0.1026*[Battery]+1.8741))/[AFRMAP]" Unit="load" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="0" GaugeMax="500" ChartMin="0" ChartMax="500" Notes="5*InjScaling*([InjPulseWidth]-(-0.1026*[Battery]+1.8741))/[AFRMAP]"/>
Please backup the xml file before you try this.

Yeah, its something you have to update when you change injector size. It can have a pretty significant affect on your load calculations, as does the proper injector latency values (which are calculated for the stock values in that formula) Only the latency values don't have as much of an impact unless the latency curve is significantly different.

I was using diff values for latency and scaling, and I changed the scaling, however the calc load values were way off. Where in the file can you change the latency values to fix this?

thanks i allready changed the injector scaling to 542 and latency values i just changed one of them to 1.9226 the original was 1.8741
my jdm injector latency values are different then the usamodels
