ok - here are some more tables which are in usual driving conditions make up the X-axis for the Throttle Map tables:

Code:
    <scaling name="ThrottleInput1" units="units" toexpr="x*3" frexpr="x/3" format="%.0f" min="0" max="510" inc="1" storagetype="uint8" endian="big"/>
    <table name="2) Potential X-Axis Throttle Table 0x5936e (interpolated/cold)" category="Misc" type="3D" swapxy="true" scaling="ThrottleInput1" address="0x59375">
        <table name="Unknown" type="X Axis" elements="17" scaling="Hex16" address="0x613e4"/>
        <table name="RPM" type="Y Axis" elements="16" scaling="RPM" address="0x6135e"/>
    </table>
    <table name="2) Potential X-Axis Throttle Table 0x59486 (interpolated/hot)" category="Misc" type="3D" swapxy="true" scaling="ThrottleInput1" address="0x5948d">
        <table name="Unknown" type="X Axis" elements="17" scaling="Hex16" address="0x613e4"/>
        <table name="RPM" type="Y Axis" elements="16" scaling="RPM" address="0x6135e"/>
    </table>
As you can see the max in the table is 429, so under normal driving conditions the X-Axis of the Throttle Maps wont go above 429 - hence I *think* if you smooth the throttle maps across you are limitting your max-throttle.

I am working out the X-Axis for these new tables as we speak.

^ thats for 53040010 here is a pic of the table:


so to be verbose - the output of THIS table is used as the X-Axis for the Throttle Maps table

apparently there is a blitz throttle controller for the X and it adjusts the speed at which the throttle valve opens. Is that what the other map could be for? Extreme mode on the blitz opens the valve 4x faster than economy mode.

Yeah i saw that where they were basically amping up the throttle sensitivity where as we are actually trying to make it more even.

I noticed this the other day when I specifically tested acceleration with the throttle pushed down at 30% and watched as boost fell off and throttle decreased as RPM's rose even though I didn't change the position of my foot. I'm not sure I'll extend the max values as high as you guys did but evening out the cruising range and widening the low RPM range somewhere between where it is and what cruising RPM's ends up being.

yeah its because at higher RPM's the X-Axis to the throttle maps actually drops (as you can see by my table I posted above, look at the 333 column, 429 -> 336)

I am not sure why Mitsu have done this...

        <table name="RPM" type="Y Axis" elements="16" scaling="RPM" address="0x61322"/>
    </table>
The OUTPUT of these tables are used as the INPUT to the TPS3/4/5 tables...

Any news?

I make small log. Delay between APP and TPS is around 0.8 second when i press the pedal and 0.4 second when I release the pedal.

This was for EDM evo. Could someone log APP and TPS delay on USDM or JDM evo? This will help to reduce this stupid delay.
