How to apply the MAF cal:
If you have an MS6, or Gen1 MS3 you need to copy the above data for the intake you have installed in the following 2 tables (MAF Table A and MAF Table B) in your ATR software. These tables must be identical. After you have copied this, save your map and flash it on the car.
If you have a Gen2 MS3 the process is the same except that you only have ONE MAF table instead of 2 (MAF Table A).
To verify that the MAF calibration is correct, drive 40 miles normally. Then take a MAF calibration log and observe the LTFTs. Ideally they should be no more than +/-10%. If this is the case then go ahead and do a WOT log. Here look that your AFR targets are met and there isn't more than a 0.2-0.3 AFR deviation from the targets under steady WOT operation.
There is no need to chase the "ideal" 0% LTFT. The LTFTs change with weather, fuel used, and even if you use the A/C a lot. The ECU is constantly adjusting and learning and as long as the LTFTs are within +/-10% you are running a suitable MAF Calibration. Your car will not run any *better* with 0% LTFTs versus 5% LTFTs. However if the LTFTs start to drift above 10% while no hardware changes have been made to the car, this indicates there is an issue and most often it is an intake or an exhaust leak.

@BAT-man this is the information you've been after

 

[BAT-man]

You guuuuise!

Just ran across this thread. @JohnnyTightlips you do realize that depending on the tuning software and year of car the voltages are different right? I ran into this comparing genwon and genpu mafcals.

I just took some info that was already out there and brought it here. It's a place to start for most people. If anyone has more to add that would be great.

I just found the CS 3.5" ID mafcal. It's different from the JBR 3.5" ID mafcal....
Not sure how to paste tables in here but it's on their site:

@JohnnyTightlips do you have the bosch map scalars also?

 

[JohnnyTightlips]

I can try and find them. Would be a good addition.

 

[Enki]

IIRC they are on the VT forums. Should be easy to find and bring back over here.

Trying to get a bit of a discussion going in here to help dial in scalars:

[Tyler Young]

Only problem I'm seeing is that it only shows 1 set of values. I tried adding these to my table in VT and topped out at 105.8 psi X 3.198 V so I'm thinking my voltage values are different than the correct values for these tables

 

[Tyler Young]

Here are starting mafcals for self tuning or just to get your car on the road. You will want to tweak your mafcal to be more accurate but this is a good place to start.

How to apply the MAF cal:
If you have an MS6, or Gen1 MS3 you need to copy the above data for the intake you have installed in the following 2 tables (MAF Table A and MAF Table B) in your ATR software. These tables must be identical. After you have copied this, save your map and flash it on the car.
If you have a Gen2 MS3 the process is the same except that you only have ONE MAF table instead of 2 (MAF Table A).
To verify that the MAF calibration is correct, drive 40 miles normally. Then take a MAF calibration log and observe the LTFTs. Ideally they should be no more than +/-10%. If this is the case then go ahead and do a WOT log. Here look that your AFR targets are met and there isn't more than a 0.2-0.3 AFR deviation from the targets under steady WOT operation.
There is no need to chase the "ideal" 0% LTFT. The LTFTs change with weather, fuel used, and even if you use the A/C a lot. The ECU is constantly adjusting and learning and as long as the LTFTs are within +/-10% you are running a suitable MAF Calibration. Your car will not run any *better* with 0% LTFTs versus 5% LTFTs. However if the LTFTs start to drift above 10% while no hardware changes have been made to the car, this indicates there is an issue and most often it is an intake or an exhaust leak.

Hey bud, could you tell me where you got the HTP info? I've got a 3" inlet and i need some other values for my mafcal tables

Only problem I'm seeing is that it only shows 1 set of values. I tried adding these to my table in VT and topped out at 105.8 psi X 3.198 V so I'm thinking my voltage values are different than the correct values for these tables

Hey bud, could you tell me where you got the HTP info? I've got a 3" inlet and i need some other values for my mafcal tables

these values are generally intended for access port and not VT right? And are a starting point as per enkis post (quoted below)

Just ran across this thread. @JohnnyTightlips you do realize that depending on the tuning software and year of car the voltages are different right? I ran into this comparing genwon and genpu mafcals.

I have used them in versatune as well without issue. Yes they are a basic starting point to get a car on the road.

I've been putting this off forever but am finally about to start this process for the first time with versatuner and i noticed that the values in my stock tune were waaaaaaaaaaaaay smaller than the values listed here. The range of values in my stock tune went from 0 - 43.59, but the recommended base mafcal went from 0 - 677.06!! I knew the bigger intake would slow the airflow across the sensor but those values seemed a little crazy.

I noticed JohnnyTightlips mentioned ATR (COBB Accesstuner), and judging by some tuning videos and screenshots in ATR, COBB defaults to g/s and Versatuner was in lbs/min! (probably some setting we can change somewhere) After a quick conversion, the recommended base mafcal ranges from 0 - 89.5 which looks more reasonable.

Moral of the story, sanity checks are good and units are important!

 

[Enki]

...probably some setting we can change somewhere...

Correct.

Also, don't plop in some random MAFCAL you find without making sure the voltages line up first. They DO differ between years and maybe even tuning solutions.

Hello from Germany. Does anyone have a basic calibration for the 4" ID Corksport Intake?
