Thanks! Email sent with title "Calibration and Log regarding Occasional AF not correct on WOT" to henry@hondata.com.

Henry is Hondata's tuner and has the most knowledge with tuning these vehicles.


@Spunkster Thank you for clarifying!

@PincheHenry Do you have a way that I can privately share my datalog and calibration for you?(fpdl file contains complete VIN number of my vehicle, posting it here I have some ...

if you want to dive into this further, your ecu is in fuel status 4 (open loop) it will use the AFM calibration to determine how much fuel to use during this operating condition. You may try and increase the AFM calibration in the specific range that its in. In your case its approximately between ...

Hello? Haven't seen reply from you.
Have you received email at support@hondata.com or is there anything I can do to continue investigate on this?

I've added AFCMD to the graph, we can see the abnormal log part, AFCMD seems correct, which drops to around 11 shortly after gear change, while AF stays at 29.4 for 2 seconds.
Compare to normal one:

Whenever you lift off the throttle (TPS=0) and under deceleration, the AF sensor is going to read a really high value (lean). This is due to the injectors not spraying/are closed, which is normal. Even during shifts, there is a short period of time that the injectors are turned off ...

Sure, I've sent an email with title "Calibration and Log regarding Occasional AF not correct on WOT" with calibration and datalog to support@hondata.com, as the fpdl file contains complete VIN number of my vehicle, posting it here I have some privacy concerns.

Vehicle is FK7 MT from China（中文名：两厢思域手动挡 FK7）

Vehicle from Hondata:
Vehicle: Civic 1.5T (2016-2021)
VIN: LVHFK7xxxxxxx
Binary: Civic Turbo MT Canada 2020
Calibration: Civic Turbo MT 2018, +6 psi high octane with some tweaks on boost pressure

Occasionally, when pull WOT from gear 1 to 3, I feel ...

I have two questions regarding the Turbo Pressure Curve(TC maximum pressure ratio)

As Civic 1.5T, the [Factory settings] map's TC maximum pressure ratio is as below, we can see the curve from 1500~2550 RPM is smooth

but in the [+6psi] or [+9psi] settings we can ...

Got it, thanks very much!

Really appreciate!! I think this is the issue, FK7 MT in China is equipped with Honda sensing(ACC, AEB).

BTW, is there any other way we can access these data?

Problem:
Hondata is not reading ABS, Clutch.Pos as in screenshots(always zero) while on friend's FC1 it's reading normally, seems weird.

BTW, what's the difference between these two
