You need to datalog and see what the actual error code is.

What error code are you getting?

It is the same idea as what is in the help file: https://www.hondata.com/help/flashpro/t ... m_flow.htm

negative trim means it is removing fuel because it is too rich and you need to lean it out.

positive trim means it is adding fuel because it is to lean and you need to richen it up.

IF you want to run in closed loop you should connect the analog output from the wideband controller to one of the analog inputs on the K-Pro board and then set it up for that wideband in the analog inputs section of parameters.

It is not a CARB version.

What is the serial number that is on the FlashPro?

I have let the software engineer know about this.

We have notified the software engineer and he will have an update for the app in the next week.

The 2017+ SI does not use voltage for the AFM, instead it uses frequency.

Use the standard calibration, not the 'race' calibration. Also are you aware the ECU cannot properly control that throttle body? hey i just bought a J37 Trottle body for my FG2 and it works fine is there any unknow danger i should be aware of? http://www.hondata.com/forum/viewtopic.php?f=29&t=18527

Is this the paid app?

Do you have a secondary O2 sensor and if so, has anything been modified?

The first step would be to try this ECU in a known working vehicle and see if there are any issues. If not then you need to start looking at wiring issues that could cause this.

It all depends on the tuner and how they are tuning and what works best for your setup.
