Speed density conversion, stock boost control.

cool

 

does any have the values for the 9653x706 roms? i'm assuming they must exist for the SD stuff?

thanks

I thought the same thing, but I found that the ROM is zero'ed out in the map sensor section.

 

Oops! Double post.

 

what were the addresses you used?

 

It wasn't about the definitions, but about the scaling for each map sensor. Give me a little bit; its been a while since Ive done it, but I'll find it for you.

UPDATE*
Here read this one:

I have the scalings already but would like to know these if possible for the 9653x706 rom

<table name="MAP Scaling" category="MAPSensor" address="670c" type="2D" level="1" scaling="uint8">
<table name="MAP Output" address="800e" type="Y Axis" elements="9" scaling="Volts16"/>
</table>

<table name="MAP Fault Trig: Mid VE Max #1" category="MAPSensor" address="29d6" type="1D" level="1" scaling="Volts16"/>

<table name="MAP Fault Trig: Mid VE Min #1" category="MAPSensor" address="29b6" type="1D" level="1" scaling="Volts16"/>

<table name="MAP Fault Trig High VE #1" category="MAPSensor" address="29bc" type="1D" level="1" scaling="Volts16"/>

<table name="MAP vs Baro" category="MAPSensor" address="283c" type="1D" level="1" scaling="uint16"/>

<table name="MAP Comparison" category="MAPSensor" address="2838" type="1D" level="1" scaling="Volts16"/>

so I can see what the settings are.

Thanks

 

Ah ok. In that case they are not necessary.

 

how come they are not necessary? still would be nice to know if they exist though.

 

the 9653 rom comes from an evo that has no map sensor and no map sensor diagnostics code.

 

I thought the map sensor information might have been added for the SD stuff? if not how does the SD know the ranges of the map sensor or is it just assumed that it is 0 - 255 and then the scaling give it to the omni 4bar

thanks

 

the tables you posted are only obd-ii diagnostics related. the sd patch has a map sensor range table.

 

Thanks mrfred!!! I've studied a lot of your post. This, once again, worked perfectly!

 

I'm a little confused.... Are the new scalings reflected in the V7 xml correctly?

<scaling name="PSIa8 OMNI4barMAP" units="PSIa" toexpr="x/(4.23*2)" frexpr="x*(2*4.23)" format="%.1f" min="0" max="30.1" inc="0.1" storagetype="uint8" endian="big"/>

is what I have and they seem very different from what I'm seeing here for the omni 4 bar?
