Hi, how are you?
This is the first time I've seen this. I can't figure it out because I'm still getting corrections in WOT.
The car is a K20/K24 build with 12.5 RC cams.
I made several maps for different friends' cars, with different configurations, but this is happening with mine.
I've attached the map and log.
There's a part of the datalog where the IAT disconnects, which is why I'm getting a DTC.
I would appreciate it if someone could see where I'm going wrong.

Re: STFT Active - in Open Loop
Does anyone have any idea what might be happening?
Re: STFT Active - in Open Loop
Most likely there is an intermittent wiring issue that is causing this.
Re: STFT Active - in Open Loop
It's the original wiring, it would be strange but I'll check.
Another strange thing that sometimes happens is that when I connect it, the Hondata's lights keep blinking until I disconnect it from the car and the computer. When I reconnect it, it works correctly.
Is it just the O2 sensor wiring or could it be anywhere?

Re: STFT Active - in Open Loop
Another thing that sometimes happens is that while the car is idling and I connect the Hondata, it revs slightly and then returns to normal.
Could this be an internal problem with the device?

What is the FlashPro serial number?
Re: STFT Active - in Open Loop
I'm not home right now, but I'll be back on Thursday and I'll share the information.
I don't know if this is relevant as additional information, but this car had a K20 engine, then a complete K24Z1, and now a K20/K24. I didn't have these problems before.
The only thing I remember modifying (without cutting wires) is replacing the MAF sensor with an IAT sensor.

Re: STFT Active - in Open Loop
I tried checking for updates, and it seems I have the latest version. However, I don't fully understand the versions mentioned in the message.
It seems I'm using the beta versions, but I don't remember selecting that.
I can try reinstalling everything from scratch, should that work?

Re: STFT Active - in Open Loop
Just download and install form the link I gave.
Re: STFT Active - in Open Loop
I tried it with everything updated and got the same result, so it seems to happen after engaging VTEC.

Re: STFT Active - in Open Loop
I don't see any errors and short term fuel trim appears to be acting normally.
Re: STFT Active - in Open Loop
It shouldn't activate in wot, I don't understand why it doesn't stay in Open Loop, after engaging VTEC it switches to closed, I can't understand why it does that.
