89970010 open loop throttle
89970010 open loop throttle
I want to change from stock closed-open loop transition to just use the closed loop for idling. my idling tps is around 13-14%.
but i'm lost since the current open load throttle is in voltage. so what multipliers i have to use/ what do i have to edit on the xml?
how the ecu decides on which table to use? (eg. between 'Open Loop Throttle Low Load' and 'Open Loop Throttle High Load')?
and btw; anyone has stock 89970010 rom?
thanks guys
--------------------
here's my xml
<table name="Open Loop Load # 1" category="Fuel" address="381e" type="2D" scaling="Load8">
<table name="RPM" address="5c3e" type="Y Axis" elements="15" scaling="RPM"/></table>
<table name="Open Loop Load # 2" category="Fuel" address="3834" type="2D" scaling="Load8">
<table name="RPM" address="5c3e" type="Y Axis" elements="15" scaling="RPM"/></table>
<table name="Open Loop Throttle Low Load" category="Fuel" address="3850" type="2D" scaling="ThrottleVoltage">
<table name="RPM" address="5c3e" type="Y Axis" elements="15" scaling="RPM"/></table>
<table name="Open Loop Throttle High Load" category="Fuel" address="3866" type="2D" scaling="ThrottleVoltage">
<table name="RPM" address="5c3e" type="Y Axis" elements="15" scaling="RPM"/></table>

to convert the TPS from volts to % you need the below scalings
<scaling storagetype="uint16" inc="1" max="100" min="0" format="%.0f" frexpr="x*255/100" toexpr="x/255*100" units="%" name="ThrottlePercentage"/>
<scaling storagetype="uint8" inc="1" max="100" min="0" format="%.0f" frexpr="x*255/100" toexpr="x/255*100" units="%" name="ThrottlePercentage8"/>
use the 'ThrottlePercentage8' for your needs
cheers
