It may be a dumb question but I am lost a little bit right now.
I am running 52680022 with the 4 bar map sensor.

I am using the rom from goldens website with the def from there.
this includes all codes as posted before.

what do i have todo to run with the 4 bar sensor?

It already contains
MAP based Load Calc #1 -> stock scaling
MAP based Load Calc #2 -> stock scaling
MAP based Load Calc #3 -> 4bar scaling

Do I only have to activate the three switches and it should work?

Omni4bar #1 0x03B6 -> 0x02FF
Omni4bar #2 0x0ED8 -> 0x0BFC
Omni4bar #3 0x0ED8 -> 0x0BFC

EDIT: ok I modified the def: load calc table 1 to be "stock x in kpa" and #2 as "4bar in kpa"
opened rom and copied scale of "stock x" to "4 bar".
saved and closed rom
modified def: load calc 1 2 3 are all "4 bar"
no further copying

fuel compensation:
modify def: 1 is "stock x" 2 is "4 bar"
copy scaling of 1 to 2
saved and closed rom
modify def: 1 and 2 are "4 bar"
no further copying

have I done it right or do I have to copy every time to the scaling?

Michael

The fuel compensation table is in reality the same table with two views.
compare the addresses of the data (not of the axes).
You'll see that they are the same.
So you dont need to modify both of them - as you would only need one of them.

If anyone needs it, here is the Omni 4 bar in psig scaling that I made

Code:

<scaling name="Omni4barMAP in psig" units="Omni4barMAP in psig" toexpr="((((x/4)*1.6151)+3.4779)*.145)-14.696" frexpr="((((x+14.696)/.145)-3.4779)/1.6151)*4" format="%.2f" min="-15" max="60" inc="0.05" storagetype="uint16" endian="big"/>

<table name="Omni4bar #1 0x03B6 -> 0x02FF" address="17f92" category="Omni 4 Bar Boost" type="1D" scaling="Hex16"/>
<table name="Omni4bar #2 0x0ED8 -> 0x0BFC" address="17fc2" category="Omni 4 Bar Boost" type="1D" scaling="Hex16"/>
<table name="Omni4bar #3 0x0ED8 -> 0x0BFC" address="17fd6" category="Omni 4 Bar Boost" type="1D" scaling="Hex16"/>

Thank you
