With the car at normal operating temperature and the engine off. Unplug the Idle Air Control Valve (IAC). Start the car and datalog the Mass Air Flow (MAF) flow rate (kg/hr) at idle. After compiling a datalog, turn the car off. Plug the IAC back in. Calculate your average MAF flow rate (kg/hr) at id...

Idle Speed

Should the “Drive Base Idle Speed” and the “Neutral Idle Speed”
have the same RPM if the vehicle has a manual transmission?

Re: Lean on light throttle

EGR isn’t your problem, it’s the tune. You have several options you can try, your choice. You can adjust your Low Injector Slope more and then start adjusting your MAF Transfer Function for the rich idle you mentioned you were getting, or you can change your Special Forces Fuel Injector Setting to 4...

If you’re max on Soecial Forces, you need to use the Commando software.

Re: Upgraded injectors

I would start building the tune using the Special Forces software and
then download it into your Explorer.
If that fixes the bogging issue then you know it’s the number you put
into the Commando software.

Re: Interface update for V23?

So if I have a STFT of 44 that would be a STFT -6, and if I have 59 that would be a STFT 9 ?

Data Log question

I just did my first data log with Recon (was using dash command before) and noticed the MAF Volts and KG/Hr numbers doesn’t match what was loaded into the transfer function. Is this normal? This was just one point. Data Log: 1294 RPM 18.00 Load % 1.12 TPS Volts 42.76 Kg/Hr 1.411 MAF Volts 80mm LMAF ...

Transfer Curve Points

Looking at where my car idle is on the transfer curve (around 1 volt)
do I need to have all the points that are below my idle point?
Can I zero them and will it an affect anything?

Re: High LTFT at idle

The fuel trim numbers are fluctuating.
They just seem high,
would like to get them lower if possible.

High LTFT at idle

My Long Term Fuel Trim (LTFT) is high + at idle.
Where can I go to adjust the AFR to richen up the
mixture without affecting the part throttle upper
RPM range AFR mixture? (Commando software)

MAF transfer function

I have an 80mm MAF sensor from a MKVIII, but I manual loaded the 80mm lightning MAF Transfer Function.
When I input some of the Air Flow KG/HR they sometimes change to something else.
For example, lets say I put in 2.00v - 127.49, it changes it to 2.00v - 126.50.
Is this Normal :?

Is there a way to add this to the OBD II Mil/Test Switches notes on the Commando software?
