Been told to always get the hpx maf over any other maf espeically the lightning but y? Some questions have been raise y the hpx maf is better, I've been told they r both just as accurate recently and the lightning maf with a Mafia is even more accurate .just wanna know for future informational purposes, thanks

hpx maf is better in a blow threw, it has a much cleaner resolution. there is nothing wrong with a lightning maf, but when it comes to blow threw the hpx is light years ahead of it. one of the advantages of a hpx maf is its range in tight spaces. a lightning maf does not do well in any other housing other than the 4" housing it comes in, where the hpx maf can be installed directly to a 3 inch pipe with little change. if you plan on staying draw threw a lightning maf can be a cheap alternative, but a hpx maf saves money over buying a lightning maf and a mafia when going blow threw

[joswo1980]

But in a blow thru configuration is 1 more accurate than the other?

[joswo1980]

Would I see a better tune with one or the other? And y?

[stal94gt]

yes the hpx is more accurate in a blow threw setup. also a lightning maf will peg extreamly early in a blow threw app if the maf is put in a smaller diameter pipe to fit the rest of the ic pipe. i pegged my lighting maf in a 3" housing with a mafia at 500 rwhp. a hpx maf will support around 600 rwhp in a blow threw setup in a 3" housing without a mafia with a mafia that maf will support over 1000 rwhp.

What does a bap have to do with the maf? lol

there is always more to a maf than what power it can support. imo a maf is one of the most imortant choices to make when building a fi car. the better the maf the better the low speed driving. having a smooth clean resolution will make the car drive like stock. if there is a lot of distortion it will be felt at part throttle.

The LMAF with a mafia when mounted correctly will provide a very clean signal. The HPX is almost idiot proof though as far as mounting configurations. It is very resistant to backwash and signal noise of any type. Neither maf will produce more HP though. The HPX has more range because it can be mounted in larger side tubing but all in all for a vehicle under 500-550rwhp both when setup correctly will provide similar results

sorry i ment mafia, i was typing fast

[joswo1980]

So if both have similar results then i basically wasted 300 between sensor, flange and pigtails for something I coulda done with 90 bucks???

[Nitmare67]

No you will need a mafia to use the LMAF with a higher HP. The HPX gives you alot more to grow with and will work better in a less than opimum location than an LMAF would have

[Nitmare67]

For a draw though configuration I almost always recommend the LMAF for starters. Its cheap to get most guys started and when the raise the boost they can just add a mafia. For blow though I go for the HPX because its super easy and clean to mount. The fact that you dont need a maf housing is a huge plus. I personally like using the 75mm maf housings in blow though apps and even a 75mm housing in draw though with the HPX for most builds. The maf still has enough range in a 75mm housing to support over 600hp which is plenty for most people. Running it in a smaller housing is what gives you all that resolution for great tuning and part throttle driving. Toss it in a 90mm or 100mm housing and the signal gets choppy VERY quick.

trust me you did not waste your money. i have tried 3 diff lightning maf setups and non of them could compair to running a slot maf. in a blow threw setup a hpx maf gets rid of the need for reducers and additonal couplers. from a dd stand point the hpx maf will allow the car to drive as it did when it was stock. with a lightning maf i constantly had bucking and serging which sucked.

[blownstang]

I have a lightning maf in a draw thru setup. When I add the intecooler I will be converting to blow thru with an hpx maf.

[Eagle2000GT]

I'm running the stock MAF and MAFia. I didn't need reducers, etc. Actually with the ProCharger kit it was just another plug in device. (Note: Of course I needed a dyno tune. The MAFia changed all the parameters.)

[Nitmare67]

I think it comes down to this. They can both be a good maf. The LMAF takes a better setup to work as well but they can work very well with a mafia.... Now they are so cheap to boot. If its your 1st blower setup and your on a budget and shooting for under 450hp the LMAF may be your ticket. If your building something and you know you want to grow in the future you cant beat the HPX because its range can be increased just by changing the housing ID. I've ran both and they both worked well. I had zero driveability problems with either but the LMAF did take a little more tweaking but when done I couldnt tell any difference with either.... at least 50% of maf performance isnt related to the maf at all. Its related to the tuner, and the setup. By this I mean having enough pressure relief (BPV,BOV) and configured to work correctly with the maf application.

[joswo1980]

Ok I think I understand now why I was told id get a more better and more accurate tune with a hpx cause I'm using a 4 core intercooler but the info dosent apply to all setups in which some setups the lmaf could b equally as good

[Nitmare67]

The intercooler doesnt really have anything to do with it.... The HPX would be better in that app because you dont need the extender (less parts), easier mounting and enough maf to grow rather large with before changing anything.... They both work but the HPX tends to work better in a variety of apps because its not very sensitve to install.... put a LMAF right before or after a bend and you'll have major issues... not the case with the HPX. I think most tuners recommend them because no matter where the car owner mounts them they tend to work pretty well. So even when installed incorrectly the tuner has a good chance of being able to tune it still. If you install the LMAF wrong the tuner either has to fix your problems because he cant tune or turn you away and set another date after you fix the maf placement.

[joswo1980]

Ya that's probably y I was told to get it cause the cx is a diy kit and he probably figured no matter how I run the pipes or where I put the hpx I still got less of a chance of fuckin up lol

[mystang0673]

I had a lmaf on my car with a zone 5 extender and it caused all kinds of aggravation. It caused my car to go lean so the tune had to be scaled for it, meaning it could have made more power with the right maf. I was on the edge of switching to a slot style maf when i sold my car. Be glad that you went ahead and got the good stuff.
