I read somewhere that the MAFS max out on a stock tune due to restrictive airflow.. The HKS Premium Suction kit shows a wider intake inlet (Is this where the MAF is located??) Mines makes a wider intake inlet as well.. Are these two basically the same or is mines intake tube a\part of a different section?... Also, would this help with the overloading MAF issue of a maxed out stock tune..

Thanks!

i dont think the maf is on there.

What makes you think something getting overloaded? cause i dont think many have any issues yet if at all. but then again most people just get full intake kits like

Which piping is the MAF located on? I forgot where, but I read the MAF is easily overloaded and widing the intake tube would help with this.. Is the HKS premium tube the same part as Mines or are they two seperate sections of the intake?

i think this is what your looking for on the pipes, no?


I think you have no idea what your doing tho. you heard? where did you hear? There are ways around this by using differnt methods. haltech has one method, ASR has a modification that can bypass the MAF voltage. you can use a diode mod and rig it up yourself. and cobb was suppose to have a 23psi limit bypass but im not sure exactly if thats finished or not.

but i dont think anyone has made a larger diam tube for the MAF to change the voltage yet. you may have heard thistles posts with talk about it. and im sure someone will make one and test it out soon, but nothing on the market right now that i know of.

Mindless, 23psi boost limit has been fixed with Cobb. We tested it to 27psi without a cut. As far as MAF housing are concerned, all of the inlet kits on the market are running stock sized housing, or else it would completely throw the tune off.

Rambino, you are correct in that running a larger diamter housing will increase throughput on the sensor.

Not true. Some companies ARE running larger diameter tubes for their big turbo kits. I myself am going with AAM large MAF intakes. Bear in mind you do have to custom tune ECU when you go big MAF and is not necessary for stock turbos anyway.

Our intake kits are running 3" tubes. As long as you get them tuned correctly, you should make a good amount of power over those over stock.

Stock turbos with actuators can peg 5.01V on the MAF sensors. Some report CEL from this which may well be defeatable, but MAF sensors have been known to fail from being pegged (Evo X) perhaps because the current is too high to heat the wire/film. Also you lose control of the fuelling and timing and rapidly have too much timing and too little fuelling when you clip.

Larger diameters work well in combination with injectors and scaling, but there are issues related to TCM manners which are being worked on.

Initially with the EVO X people where upgrading their intakes, including the actual MAFS housing. This caused cars to run much leaner because the MAFS was recording less air than what actually was be pushed into the engine.

Eventually people learned that you had to rescale the MAFS (using software0 to account for the change in housing diameter and to safely run the car. The same should be true of the GTR.

The same issue arises on every MAF sensor car for people that aren't aware of the issue from other platforms. It is easy to tune around if you know what you're doing, but on the GTR there are complications with the TCM, so you can't just deal with the engine's perception of airflow in the usual way.

...Bingo... ;)

....I am working on a solution for this as we speak....more details to come....

You nailed it!!

JB, im working on a set of MAF's and the scaling for them to accommodate this, ill forward all relevant info to you
im also going to do a few with injectors like i did before and see how it goes. the current car is fast as hell and has NO tranny issues

I wouldn't use the original injector scalers, I have suggested replacing them with a proper injector scaler that has been found that actually changes the injector pulse widths in the logs as you would expect, but I think we're waiting to do big changes to the software until we have all the TCM stuff all tied up to put it all together.

OK ill leave it as is for now. ill bug joe about the new software the 12022 seems to work well
