Disabling Fuel Trims in MED9
« on: August 24, 2021, 12:53:55 AM »
I am working on tuning FKKVS...
Per FR:
5.2.2 Partial function NOLRA:
- Formation of the shutdown bits B_noora, B_nofra, B_noorat and B_nofrat.
The code word NOLRA can be used to switch the areas on and off individually. ¨
Bit 0 in NOLRA = TRUE: B_noora is set => area ORA is neutral.
Bit 1 in NOLRA = TRUE: B_nofra is set => area FRA is neutral
Bit 2 in NOLRA = TRUE: B_nofrat is set => It is not possible to detect a mixture error via temperature dependent correction. ¨
Bit 5 in NOLRA = TRUE: B_noorat is set => It is not possible to detect a mixture error via temperature dependent correction. ¨
- Formation of the bit for reset readiness of the integrators in case of error memory clearing (B_lrareb) ¨
NOLRA bit 3= FALSE can be used to set the adaptation to neutral in case of error memory clearing. ¨
NOLRA bit 4= FALSE and BIT 3 = TRUE can be used to set the adaptation to neutral in case of a threshold overflow in the DKVS (B_edkvs = TRUE).
can be set.
For projects with 2 fill detection sensors (HFM and P sensor), depending on the main load sensor, the adaptation is switched between both additive adaption corrections. If ¨
B_dssakt = True, then the main load sensor is the intake manifold pressure sensor. Here the range is limited by parameters with index 3. With a HFM system the
range is limited by parameters with index 1.
Would setting NOLRA to: 11100100 be correct?

00100111 seems to be correct.

Well yes because when you write a single byte you always write MSBit first. And MED9 is MSB First anyway.

Yeah, I don't think this is right yet. It's still doing some type of adaption after driving for a while, you can just feel the car improve from when it was flashed and 30 minutes later everything is pretty smooth.
