Bad measurements after SXTH Element cold air intake

I don’t have a check engine light on but saw this when checking live data

live data on what tool and what version firmware ?

is your maf facing the correct way?

 

[4runnerfrank]

Yes I double checked. I’d also assume facing the wrong way would lower the flow

is your maf facing the correct way?

yes I double checked and wouldn’t that lower the flow

its a CAI so it makes sense it will increase airflow better than factory. I wouldn't worry about it if it doesn't cause a CEL.

Maybe a tuner can chime in? @CAMTuning

Might be vehicle has to be running or fully warmed up. Mine had ones like that too. Wasn’t worried because no codes are coming up

This is a common misconception: intake does not necessarily increase airflow but it can change the way that airflow is measured. If the diameter of the tube or the placement of the MAF is in any way different than stock, that is what causes check engine lights or variations in air/fuel ratio


My suggestion to the original poster is to look at long-term and short-term fuel trims at idle and not worry about the airflow ranges. The trims will let you know how hard the ECU is working to drive the air/fuel to target. I have tuned dozens of this same intake and have one on my personal truck. I do see slightly higher fuel trims than stock when no tune changes are made. I can continue to help you on this post or you can PM me.

if the MAF was backwards, which is actually impossible to install backwards because of the screw spacing on this platform, the vehicle would not run at all.

Banks has moved the MAF farther down on the inlet tube and closer to the throttle body. Do you think that’s why their power numbers are better?

Their power numbers are likely better because it makes it run a little bit leaner. Right after install you will see higher power numbers because open loop fueling is leaner than factory. After you drive it for a while the long term fuel trims will compensate for this and air fuel ratio will return to normal and I would expect the power gains to be reduced. MAF location only affects the calculated airflow, and can be influenced by how close the MAF is to a bend, etc.

Hey everyone, jumping in here from the SXTH team.
@4runnerfrank , Cam from CAMTuning is spot on regarding fuel trims. Since our intake utilizes a larger-diameter induction tube to reduce restriction, the velocity of the air passing the MAF sensor changes compared to the factory housing.
Without a CEL, the ECU is likely well within its "authority" to compensate. As suggested, keep an eye on your Long Term Fuel Trims (LTFT). If they are within 10%, the car is happy.
Regarding the MAF location and power:

• Sensor Placement: We place our MAF to ensure the cleanest possible laminar flow. Moving it closer to bends or the throttle body can "trick" the sensor into reading leaner, showing temporary "paper gains" that the ECU eventually trims out.
• Reliability: Our focus is on consistent, repeatable performance that doesn't rely on leaning out the factory safety margins.

If you see those trims creeping higher or want us to take a look at a data log, feel free to reach out to us directly or shoot over a PM!

Awesome thank you very much!

So, what you are telling me, your intake out performs the one that I bought?
