As I am reading the instruction manual, I have come across some questions.
1. Installation.
If upgrading the MAF sensor, remove the vehicle's original MAF and install
the upgraded MAF. If a plug-and-play harness is available, follow the
instructions included with it. Otherwise wire the new MAF such that the
signals use the original vehicle wiring. Install the MAF Translator Gen-II
wiring, splicing in to the MAF signal wire so the MAF Translator Gen-II can
alter its signal. If the original MAF had extra signals, wire the analog
outputs to those ECU wires so the MAF Translator Gen-II can generate
those signals. Tap the TPS and RPM signals.
QUESTION: Now since I have the plug-and-play harness, do I need to tap into the TPS and RPM signals? If so, how is that done?
2. AF Low: Low load AF tune vs. RPM
QUESTION: What is the full purpose of this function? The AF LOW is for idle? Do you need to have a wideband connected to the GEN II to make this work? Do I splice my 5v analog and ground from the wideband into the GEN II, VIA Orange and Purple wire? Now if I do this does it kill the O2 going to the ECM? Now the RPM is set to what the chip was burned to idle at? What if your idle is 900rpms and you can only choose 800 or 1200 rpms on the GEN II? Which one do you choose? Now what about the AF piece. What is the function here? Is this where the wideband will help control the amount of fuel? Getting your BL back to 128? What should the AF be via wideband? (E85)
a. AF Mid: Mid load AF tune vs. RPM
QUESTION: What is the full purpose of this function? The AF Mid is for cruising speed? Now do I need to set the RPMs equal to what the RPMs are running at 60mph? What should the AF be via wideband? (E85)
b. AF Hi: High load AF tune vs. RPM.
QUESTION: What is the full purpose of this function? The AF HIGH is for WOT? How do you know what RPM to set the GEN II? Your peak RPM? At this point and you have wideband connected, is the AF on the wideband need to be 10.5? (E85)
3. MAF Sensor Tune: User AF tune vs. MAF flow.
QUESTION: Please explain this one to me..
4. MAF Translator Gen-II Setup
The vehicle can be equipped with a larger high performance MAF than was
originally installed. The new MAF is installed and wired to the MAF input
wire (yellow). Configure the MAF Translator Gen-II MAF Input to match
the sensor installed on the vehicle. The MAF Output mode is set to match
the vehicle and ECU/ECM. Frequency MAF signals are sent on the
Frequency Out wire (yellow), voltage MAF signals will be sent on either of
volt out wires (brown or gray). Be sure to configure the volt out mode for Volt MAF . Some vehicles have MAF sensors with other functions or
signals. These other signals are typically Barometric pressure and Air
Temperature. These MAF sensors are actually "Air Volume" sensors, and
the ECU requires the temperature and pressure in order to calculate the
airflow mass. When using a true MAF sensor, the air temp and baro signals
must be kept constant to prevent double-compensation. These other sensors can be simulated by the MAF Translator Gen-II, using the V Out 1 and V Out 2 signals. Set the V out 1 and 2 mode to Use Setpoint in the Config page, and set the output voltages to normal levels in the Setup page.
QUESTION: This setup says that I need to have the volt out set to "VOLT MAF" , But the setup instructions on the board read as this "V Out 1 and V Out 2 signals. Set the V out 1 and 2 mode to Use Setpoint" Now how do I know what the output volts are suppose to be? What is normal levels?
5. Parameter setting details for all pages:
Config:
MAF-In: Select function and scaling of MAF output
Select from list of available sensor types.
MAF-Out: Select function and scaling of MAF output
Select from list of available scalings.
RPM/Engine: Set to the number of cylinders of the engine
(exception: 96+ LT1, 4 cylinder)
Displacement: Displacement in Liters. Used to calculate Engine Load
Load Source: Determines the method used to determine engine load.
Engine load is used to determine which of the High Mid or Low load tune
settings are used. Selections are (scaled in KPA), TPS (320 = 5
volts), or a MAP sensor connected to the Aux input.
Wideband O2: Select scaling of wideband input from the following list
Innovate LC1
Innovate LM1
AEM Gauge, AFM-1, other (0 volts@10:1, 5 volt @ 20:1)
Tech Edge (2B02) Wideband
Zeitronix ZT2 Wideband
Dynojet Wideband Commander (0-5 volts = 10:1 - 18:1)
AEM interface (non gauge unit)
DIY-WB
Aux Log Mode: Determines logging function of Aux input wire.
No Aux Log (Reads only voltage)
Log EGT (requires adapter)
Log 2 Bar (calculates and logs MAP pressure from the aux signal)
Log 3 Bar (calculates and logs MAP pressure from the aux signal)
Log 3.5 Bar (calculates and logs MAP pressure from the aux signal)
Log 5 Bar (calculates and logs MAP pressure from the aux signal)
Question: Why do we use "MAF/RPM" for the load source? If we have a wideband connected, then do we choose "MAP Sensor"? On the wideband, I thought that we were suppose to have a 10.5:1 AF. I am confused about the AEM settings (0 volts@10:1, 5 volt @ 20:1). What is the difference? Why would you have an AUX map when the ECM/GEN II already reads the MAP?

F Out Max: set for the maximum frequency that will be sent out the MAF output. Can be used to prevent fuel-cut, or intentionally lean out the top end. Set to 0 to disable frequency limiting.
MAFLim TPS: TPS value below which MAF Flow is limited to the below
settings.
MAF Limit: When TPS is below the MAFLimTPS, MAF flow is limited
to this. This helps reduce decel richness.
MAF /Krpm: Second limiting factor. This setting, multiplied by
(RPM/1000), is added to the MAF Limit and the sum becomes the max allowable MAF Flow when TPS is less than MAFLimTPS .
Idle Flow: When the MAF reading is below this, the MAF reading is
filtered or smoothed to help improve idle in cars wit turbulent idle airflow. Idle Filt: When the MAF reading is below Idle Flow , the MAF reading is filtered using this factor. Adjusts 0-2.50, lower numbers are filtered more Setup:
