check F4310, I think it's a flow conversion rpm*mg=mm3/s

I dont think that can be possible.
mm3 > mg = app. 100 > 83.33.....depending on fuel temp.
So rpm and IQ would be flat ramp rather than a curved one as rpm is irrelevant.

That 9000 max axis value does appear to be used for an SOI limiter.
RPM vs Torque NM = SOI.
imo

9000 is also used as the default value for the torque limiters gears 1-6 & R.
RPM = Torque NM

F4310 does appear in the rail pressure area.
So I would think it is rail pressure related.
RPM VS Torque NM = ???

Whatever it is is directly proportional to rpm.
so 6000rpm = 3x 2000rpm value.

Torque remains in propertion to value until 400nm.
When you go above 400nm the values begin to drop off.
The Max torque of the OEM car is also 400nm.

Hi Mr. Relic
What kind of data there are maps in the area that goes from BFF70 to C0000 (8 bit data)?
In what cases are touched?
Thx

That area just before c0000 is the checksum area.
There is another checksum area just before the end of the file.
;)

This area is changed by "checksum on write" cables ect.

Some tuners will add their tags at the begining of a file.
So the checksum before c0000 will change.

Nothing before c0000 will change..ever...other than adding user/software tags in white space.

Hi guys, i'm looking at edc16c39 fiat maps and I have found very similar maps, not only one map but sequence of map and scales. Look this "volumetric efficiency"

Look at the end the 4 single are displacement of engine, normalized battery voltage and SRC min and max battery voltage.

I will have a butchers tonight ;)

Theres is multiple tables with values less than 100.
But if you have found a matching sequence of tables that is excellent (3x 10x10 in sequence).

Many tables use factor 0.012207 = %
But there are signs 1:1 is used as well.

Would I would say though.....the Honda like the bmw edc16c31 only uses mm3 for the duration tables.
All other values are mg and torque.
So I still think this is most likely NM vs RPM.
