Boost limits(fuel cut) is out of whack on these defs.

Hey Guys, I'm new here, and I hope I'm not resurrecting this thread, but I wanted to follow up.

From what I understand, there are three tiers of these definitions that indicate whether these definitions have been vetted or confirmed by the community. The last user, Alexmartynyuk, indicated that there were tables out of whack. I have a 2019 STI, and I am interested in moving from the AccessPort to OpenSource, so this topic is very relevant to me.

How can I help/contribute to verify these definitions?

Has anyone verified Alexmartynyuk's comment? I thought I read someplace else that the table he is referencing is actually located somewhere else on the newer cars/ecus.

I am also interested in this for the same reason. Would be happy to put into a bounty to get this definition properly sorted.

Anyone willing to sort out this definition?

The Boost Limit (Fuel Cut) table as defined displays the correct values.

The raw data from the ROM looks like this, the same as viewing the table in Raw values.

The axis values are not defined correctly, it should be Engine Speed (RPM).

Thanks for looking into this. I will poke around in my ROM/Def and see if I can make sense of this.

I have successfully tuned this ECU using the td-d definition. It is missing the A/F #3 corrections, though, not a show-stopper.

Thanks for the update. Just out of curiosity, what level of tune did you do? FBO, Rotated, OEM+?

I realized that my table axis are wrong with the current GitHub definition...

For some reason there were 3 tables with almost the same name in the definition, I figured out that mine uses the "Boost Limit (Fuel Cut) " noticed the 2 spaces at the end...

The table had "Atmospheric Pressure (PSI)" as the Y Axis, which should have been "Engine Speed (RPM)", as you pointed out. The other Axis was correctly labeled and already converted to "PSI Absolute", which is much easier to work with than "Raw Value".

I was able to fix it, with this code :

Code:

    <table type="2D" name="Boost Limit (Fuel Cut)  " category="Boost Control - Limits" storagetype="uint16" endian="big" sizey="15" userlevel="1" logparam="E52">
      <scaling units="psi absolute" expression="x*.01933677" to_byte="x/.01933677" format="0.00" fineincrement=".01" coarseincrement=".1" />
      <table type="Y Axis" name="Engine Speed" storagetype="float" endian="little" logparam="P24">
        <scaling units="RPM" expression="x" to_byte="x" format="#" fineincrement="50" coarseincrement="100" />
      </table>
      <description>Fuel cut will be activated when actual boost exceeds the corresponding threshold in this table multiplied by an atmospheric pressure multiplier.</description>
    </table>

After more poking around trying to transfer a cobb stage2 map to RR, I don't see "Primary Open Loop Fueling Compensation (Closed Loop Delay Max. Load Not Exceeded)" tables; however, it is defined in the "Closed Loop Delay Max Load (RPM)" table description, which is a table that is defined in the RR:

This is the maximum calculated load to allow for a delay (if one is called for by the "Closed to Open Loop Delays" table) when the decision to switch from closed loop to open loop fueling is made. If calculated load is greater than or equal to this value, the current delay will be set to zero and the "Primary Open Loop Fueling Compensation (Closed Loop Delay Max. Load Not Exceeded)..." tables will not come into play. When calculated load drops below this value (with hysteresis), this table will have no effect on the delay and the "Primary Open Loop Fueling Compensation (Closed Loop Delay Max. Load Not Exceeded)..." tables will be active.

Not sure how important this is, however cobb has zeroed out the table from stock -100 values and noted: Negative values in this table will cause primary open loop fueling to be leaner than expected or the open loop transition not occurring when expected.

Has anyone using these defs had any issues with the ecuflash def? When I open the rom the tables show up in the menu on the left, but they are nearly all grayed out and give the message “This definition is invalid or incomplete.” Not sure if I’m missing a step or something… I got the RomRaider defs to work, however the tuner helping me wants to have the ecuflash working also

sounds like you have the definition for the rom but not the matching 32bitbase def to go with it.
