Regarding the Primary and Secondary Oxygen sensor settings:
As I understand it, the Primary O2 sensor controls AFM-based closed-loop feedback and fuel trims (S.Trim / L.Trim).

However, in my testing:
- When I disable the Secondary O2 sensor, [AFM and : S.Trim and L.Trim stop updating / remain ...

I am not sure if my understanding is correct: if WOT determination is based on AFM.c, why does the ECU still not enter WOT in the datalog even though AFM.c has already met the set threshold?

From the datalog, I noticed that during initial tip-in / acceleration, the Boost Pressure (BP) doesn't match the BPCMD . Could you please advise on how to address this discrepancy?

is any new update for this ?



Record a datalog from a cold start and make sure it records driving and getting up to full temp then post here.

Please reference the attached logs regarding the CVT temperature issue.

Hi Hondata,
Regarding WOT determination, I would like to know under what conditions/at what stage we should tune this, and how we can verify in the datalog that the setting (Mass/mg) vaule is configured correctly?

Torque it never had and will never have as that is a Type R channel. For the temps please post the calibration used and a datalog showing the issue.

lease check the attached calibration (.cal) and datalog (.fpd) files.
The CVT temperature reading appears to be incorrect. After driving for over ...

Is this expected behavior? I can actually see the Torque info on the Hondata mobile app, but it is still not showing up in FlashPro Manager.

From Help, About, what is the version of software you are using?

Software version: 4.7.7
However, this issue has already been occurring in earlier versions.

I tried recording datalogs multiple times, and whenever a log exceeds 2 to 3 minutes, the issue occurs—making it impossible to download ...

maybe 10min ~ 20min

Just to update this thread.

For us CVT users running on 92octane(100RON.) In reality, you would like to add +9psi(24psi) from 4000rpm upto 5500rpm only and quickly drop it to +6(21psi) upto redline or around 6000rpm.

The reason is, I found that running higher than 21psi after 5500rpm is ...

Hi Hondata,
I found an issue where downloading or saving a datalog fails whenever the recording duration is too long (file size exceeds ~2MB / 2,000,000 bytes).

Is there any workaround or solution to improve or resolve this?
