Hey Guys

I want everything the speed density project brings but i need it on a 2007 6MT Legacy gt-B, A2UG002T
could these patches and code be implemented?

More ROMs will definitely be added over time. But I don't want to promise any timelines because that always gets me into trouble.

Sweet Bud, but when you start working on other ROM's Pls add mine first
HA HA HA

The SD Engine Displacement parameter in the definition should be updated to units litres instead of units cc.

Hi,
anyone has changed the EcuFlash XML for ecuEdit?
If I write down the XML's for ecuEdit, I can see all Maps but with an wrong content.

Interested in trying this out on A2TB001L (USDM 08 LGT-B). I'm mostly interested in SD if anyone is able to help get this ported to that rom.

here is a log of me rolling along in neutral revving it up with the clutch in, letting it build boost and then dumping the clutch in 3rd. Note that I do not get knock until after the clutch is engaged. I have FFS set at 4000 as i figure this will be easier on the engine/tranny for now.

Any thoughts?
I notice that my throttle does not show 100%, i am sure i had it pegged...
i will try to get a better log but here it is.
severe knock anyways..

I'd also like to get a hold of it for A2TB001L. Was there any porting efforts made?

Would it be possible to expand the number of cells for the VE table? I'd like a bit higher resolution if it's possible...

For comparison I've seen other SD systems with as many as 22 columns for the pressures.

Although I don't think it's really necessary, I've received several requests and will be using larger tables on my future releases.

If you need finer control on the existing SD, rescale the manifold pressure load compensation table to the range you need finer control of.

Increasing the columns to 18 like the SD ROM for 16bit would be awesome! Then we can use the same spreadsheets to tune fuel.

Also, changing the axis from MRP to MAP would help a lot. Because the ECU thinks in MAP, so should we.

My current build is set up with 24x24 tables, which is compatible with the 32bit SD spreadsheet.

The axis used by the logic is MAP, but the scaling used in the definition MRP-Sealevel is offset for ease of understanding. If you would like to read in MAP, feel free to edit the XML. Just change the scaling on that axis to "psiabsolute".

Hopefully in the future RomRaider will have selectable scalings, and perhaps an option for the user to input his/her current atmospheric pressure or read it from the ECU when connected.

24x24 would be great.

I see where the load axis can be changed in the xml. Thanks.

I'm a little confused.. what's the difference between these two and what is used to actually determining load when running SD? I'm still on MAF mode but logging to compare and get my VE table roughly dialed in.
SD Calculated MAF (g/s)
SD Sensor MAF (g/s)

I don't recall exactly how NSFW had it set up in his version, but I believe it's like so:

SD Calculated MAF (g/s) is the calculated airflow using the SD algorithm and VE table.
SD Sensor MAF (g/s) is the calculated airflow using the Maf sensor voltage and MAF scaling table.
