MAF adjustment

[f1yen]

Hey Guys, since winter cold air has come, I am hitting fuel cut (not just the stumble) but the WHAM cut.
From what I gather this comes from the MAF sensor reading 5 volts.

I have also been reading into Short term and long term fuel trim (STFT LTFT)

I do not like the thought of the joeP, because as I recall, It hooks up to the 12 volts? I am not a fan of having 2 voltage sources in a circuit. *WHOA EDIT I looked back at my old notes seems like the JoeP hooks up to ground not 12 volts!*

I also am not a big fan of a voltage clamp, because I still would like the car to hav its safety net if (lets say a hose blows off) I overboost.

So my question was, if I do some voltage division ( MAF signal in >(Resistor)> T junction >(Resistor)> ground) the t-junction is where the signal wire goes to the ECU. And you can arrange the resistors to change how much voltage drop your signal is towards the ecu.

This setup would modify the voltage down slightly, which should be compensated by the LTFT. And then this still has the ability to send the 5 volts to the ECU which would save the engine from overboost.

My thoughts:
The STFT will immediatly see that the MAF is off (kind of like the way a sensor gets bad, or drifts off of spec) and will eventually adjust the LTFT. This will assign new values for LTFT (open loop control comes from LTFT). So when all is said and done, I will have a MAF that will not hit 5 volts(keeping me away from fuel cut), I still have the safety net of not having a voltage clamp, and the LTFT should adjust for the difference.


Does this logic sound good?

Thanks,
Kyle.

So since I found that the joe P does this setup- pretty much, then would It be more reliable for the system to adjust the LTFT with the drifted MAF sensor (adjusted by me), Instead of surprising the ecu with a redux of signal when the JoeP kicks on?
