VS M4.4 tuning dead? Start again here?

[A1304]

I don't use VAST's WBO2 modulation.
The "14POINT7 SLC Free 2" manual doesn't have any calibration information, but there is a screen with AFR readings. I compared the readings in TUNER Pro.
My catalytic converter is removed, and the O2 sensor is in place of the rear O2 sensor.
It's further away and colder. The readings were around 15-15.3 AFR. I changed the formula, and the readings became 14.7 (((X* 0.0196078) - 0.2)*2) + 10.4-0.7).
The readings may not be accurate, but they will be across the entire speed range.

English is not my native language, I apologize for the inaccurate translation.

My old SLC Free has the same thing. My Spartan 2's output a couple of calibration voltages on start-up, seeing as there is no native visualization to the unit.

I'm guessing you have your own programming for the modulation, so I don't know how you're handling things and how you're using the AFR values.

Why is your O2 sensor so far back? You could be getting some oddities from that, regardless of what the readings are.

Yes, the oxygen sensor needs to be moved closer to the main O2 sensor. That's in the summer plans.
The "14POINT7 SLC Free 2" has two outputs: 0-5 volts and 0-1 volts. I wanted to connect the 0-1 volt output to the main O2 input and screw in the LSU-4.9 oxygen sensor instead. It didn't work with the O2 controller ground; most likely, one of them will work.

Hello. It is possible to read bin from M4.4 by a K Line ?

Nope.

Thanks for reply

The last 64k can be read like M4.3.
32k-64k in first half is possible with higher voltage.
First 0-32k require short circuiting an address line and reading 32k-64k.
So not very practical or safe, but not totally impossible.

What parameters and maps affect the speed of STFT regulation
how to increase the injection time the VE card is not very effective.
