Trouble with MAF sensor

Lately I got code from my MAF sensor which P0101 showing has problem with performance circuit, I'm planning to replace with Jet performance MAF sensor as I use cold air intake my question is anybody in here use this MAF and showing better performance then OEM one, the price is more then Denso one and the review said better throttle response then Denso one

Thank you Guys

 

I’d stick to a Denso unit.
If you are looking for a MAF calibration to aid the CAI, and your are on a budget, look at the URD MAF PnP.

The best option would be a “real” tune such as OTT or the like.

But you pick the one that makes you happy.
We all have a budget.

 

I thought about URD MAF PnP too and compare with that but both more like need a tuning after installation and I already got tunning with OTT so probably doesn't do any good if I switch from Denso to either both of them right.

I'm agree with you about pick one that make me happy! Thank you bro

 

If you all ready have an OTT then I’d go with OE Denso MAF. The JEGs MAF is probably going to screw with the stock tune?

Let’s ask @JustDSM

I think you should just throw the Denso in it and call it done. If you got a tune it is likely already compensating for the map data.

 

I'm 100% agree with, I don't want mess with OTT tuning. I will get Denso tomorrow then. Thanks man.

 

Have you ever cleaned the oem unit with mad sensor spray?

 

What kind of CAI are we talking? The stock one is a CAI so any aftermarket one could have potentially caused your first MAF to fail due to poor filtration. They're known to not only let in more dirt and debris, but if your CAI has an oiled filter that's a great way to gum up your MAF sensor and throttle body.

 

I did many times already

 

I use K&N CAI one and a lot ppl say it's ruined your MAF sensor because the filter has oil on it, so I clean my MAF but not my throttle body and take it away K&N filter and change it with dry air filter one.

 

You’re throwing the P0101 code due to the intake. It changes the ID of the tube where the MAF resides. This change means the lookup table is no longer properly calibrated so the mass of air entering the engine is no longer accurately accounted for, thus skewing the internal airflow/fueling calculations. This leads to the ECU having to make large corrections in the way of fuel trim corrections. Once the trims reach a certain threshold, they’ll trigger the code you’re experiencing.

You need to have your MAF rescaled/recalibrated in the ECU via a custom tune. You do not need a new MAF sensor. The old one may be coated in oil due to your K&N filter, but some MAF cleaner will do the trick.

Your tune is configured for the OE intake.

You’ll have to get the software or visit one of our retailers to have your calibration adjusted.

 

Hi Justin,,

So all bc the shape of tube CAI causing this code, how about the position MAF sensor ? the most CAI put MAF sensor on top of tube and only K&N they put underneath the tube.

I will search your retailer to adjusted.

Btw the software you mention is HP tuner Justin.

Thanks for your input Justin.

 

The location and orientation of the MAF can also have an effect. Generally, most of the error with intakes in the ID of the tube, but the location and orientation can affect how the airflow is sampled and/or how turbulent the airflow is at a particular location within the intake tract. This all can affect how the MAF/ECU measures the airmass flowing into the engine.

Happy to help!!

Roger that... Great information!

Thanks for the clarification Justin!
