Why aftermarket MAF's don't work
I have to replace mine. That is why I'm getting the bucking I was telling everybody about.
Also, it's not a good idea to remove the screen :eek: GM parts direct has MAF's for $132 for the Alero 3.4 http://forums.corvetteforum.com/showthread.php?t=854920 http://www.silveradoss.com/forums/in...showtopic=3333 http://www.gm-trucks.com/forums/inde...howtopic=70752 |
And this is a detailed reasons why from the Corvette forum

But descreening never was an issue actually two out of the three sites said it was fine.

these guys have truly lost their minds....I hope he doesn't speak for their whole group. I'd be so embarassed.
"MAF measures Air Volume...blah blah...fuel...blah...retard...etc...." I'm sorry, but most people that know something about tuning also know that with a larger MAF, comes different MAF tables in the PCM. You don't just slap on a bigger MAF and go. KR comes because they aren't changing the TUNE to go with the different MAF. I'm running a damned LS6 MAF on a little 3400 V6 without a problem. |
i've been running a screenless maf for 3 yrs with no problems, i removed mine because i damaged the honeycomb while doing other modifications, but it has caused no problems at all.

wow..what retard would change out the maf without tuning >_>

and you're right, there SHOULDN'T be a problem in running without a screen. Although it does serve two functions, one being that it keeps larger pieces of debris from entering the intake, the other being that the "fins" are supposed to "straighten" the air flow before entering the metering wires in the MAF...the truth is, the air flow should be reasonably stable within a couple of inches of the MAF as it is. Might be beneficial if your MAF is located right after (inch or two) an elbow. Otherwise, it won't make that much difference. As far as people believing that removing it reduces flow restriction, that is a myth as well, unless it is damaged or fins are bent, as in your case, then removing it would be beneficial to flow. |
So basically just keep the stock maf on our aleros. I have a CAI and I wanted to add a high flow maf like off summit racing to complement the intake. But, from what you guys are saying it will be pointless. Also, what about a high flow cat?
I am about to install the DHP PCM 1.0 and I wanted to add a high flow cat as well? I guess I will just stick with the CAI, 180 t-stat, and cat back exhaust with the stock cat then? |
basically, unless you're installing a MAF for a much higher air flow rate than factory, yes. It would be pointless.
My LS6 MAF is because it will accomodate a much higher resolution at the flow rate that pumps through that massive turbo. "High-flow" maf's would only benefit you if you were pushing a serious N/A build or a boosted setup. CAT's - My recommendation would be a CATCO with stainless core, not ceramic. Make sure you order one at the same diameter as your cat-back, not stock size. Cats already restrict flow as it is, and if you go 2.5" catback system with a 2.5 high flow, then you'll be ready for it when you upgrade to headers. |
I thnk You can do an downstream O2 delete with a the DHP PCM 1.0. I know I couldn't do it when I bought mine, but that was a while ago.
The aftermarket MAF's help you if you have serious mods like a cam, turbo, s/c, and so on. Even with everything I have done to my motor, it still doesn't benfit me to go with the aftermarket one |
you have to have a programmer, either DHP or HPT to remove the downstream o2.

You did stuff to your motor? :ninja: |
^^ Yes I did, but a stcok MAF still is best for my set-up.
After I get my stage 2 set-up, I'll need the aftermarket |
Think it's time to replace my MAF. I'd rather have a brand new one and this is the only one I can find. Anyone have a link to anywhere cheaper?
