It appears that this is a new product (well, at least, I've not heard of or seen it before) and wondering if anyone has any experience yet:

Turner Motorsport N52 Intake - E9x E8x (N52)

So, not a fan but no experience with it.

What are better options? I've done the charcoal delete. I recently did the 3IM and just looking at options for what should be the next project.

If you've done the charcoal delete, maybe get a silicone intake boot. Pretty much everything else is just BS. Intakes do nearly nothing for how much they cost.

Maybe do the Dinan airbox mod if you're just bored. But I still think there's basically no point.

honestly my favorite (and cheapest) mod was the MAF delete. Hopefully you didn't already pay for an expensive 3-stage tune though..

I did the Rev Motoring silicone boot when I did the 3IM. What about some of the BMW air boxes? Any benefits at all?

How does the MAF delete mod work? You get get rid of the MAF and code out the code? What does that do?

Not really. Some people like the euro airbox because it makes filter changes easier, but it doesn't seem worth it to me (it's still pretty easy on the US airbox) and it doesn't make any difference in power.

N52s were designed to run without a MAF. They later added it back for emissions reasons. So you would need a tune based on the original no-MAF calibration, which were still used all over europe. It is NOT alpha-N and it's NOT just making it run in limp mode by deleting the MAF error codes and clipping a wire (like ESS does).

I think it drives smoother (especially at low speeds), it's more responsive, and basically you will never have to worry about your MAF getting dirty because it doesn't have one.

Thanks hass for explaining the MAF delete mod. Does the mod affect gas mileage at all? How much does the mod usually cost (i.e., the cost of the tune)?

[hassmaschine]

no it doesn't.

the IAT is around $65 but you can try it with the MAF first (it just ignores the MAF sensor and reads the built in IAT instead). There's a free MAF delete tune (for 3 stage swaps) you can try, or a couple people can do proper tunes for it as well.

If you have headers, the free one won't work (it relies on the O2 sensor feedback loop which gets messed up with headers). A custom tune is required for that.

[cpie168]

Sorry for the dumb question but what is IAT?

[Bufalo]

Intake Air Temperature - it's integrated into the US MAF sensor, or it's standalone on the european cars.

[cpie168]

Thanks guys.

Intake Air Temperature.

the euro IAT is much smaller than the MAF of course - theoretically it should reduce intake restriction a bit:

I have a question that’s been on kind mind for a little while since the subject came up...

I asked Bob about doing a MAF delete tune for my car about 6 months ago. Back then he said he wouldn’t mess with it until the n54 intake leaks issues were solved. So after I redid the intake mounting sleeves and fixed that I asked again.

So this was like 2 months ago and he said if it was his car he wouldn’t do it. He said with the US based tunes the maf delete can run rough and in general it’s not smooth running for a car you want to daily. He said the couple extra HP wasn’t worth dealing with it and suggested I not do it. So we left it at that.

hassmaschine are you using a US based tune for your MAF delete? Is there a way to start with the euro tune which is Maf delete from go and then add mods like the n54 intake, headers, MILV’s, etc?

You seem to really like the Maf delete tune. My car is running great with the MAF and all my mods, the way it runs and idles is just like stock which still amazes me for the amount of mods on it. I kind of agree with Bob that I wouldn’t want to give that up but it seems like you really like how your car runs.

[hassmaschine]

I don't think Bob is doing it the same way as I am (I thought he was, but if he says it runs rough, then I don't think so). My car definitely does not run rough. Remembering that these cars came that way from the factory!

When I first did it, honestly, I couldn't even tell a difference in idle when I started it up cold. I was expecting *something* but it was exactly the same with or without the MAF. I didn't notice a difference until I drove it.

I think if you saw and drove my car and I didn't tell you there was no MAF, you would never know. Keeping in mind my wife also drives it.

I also solved the issues with the O2 feedback loop being messed up with headers and no MAF. Actually it's messed up if you have a MAF too, but the MAF masks the issue. Basically with the high speed wide band sensors, changing the position of them in the exhaust throws the loop out of wack - your LFTF's will end up over 20% and you get a CEL (plus it runs like crap).

This is also why ESS couldn't tune their superchargers to work with headers, because they just clipped the MAF wire, ran it in limp mode and obviously they weren't going to retune the feedback loop for headers.

There's at least one member of this forum running my MAF delete with headers - the only issue I'm working on is for MSV80, the calibration I based it on doesn't have cruise control enabled. But I expect that is solvable once I find the time.

I have the Euro and it's not much easier to get out. You still have a ton of Etorx screws to take off and still need to disassmble the front air dam router from the main box to remove the cover.

It LOOKS a lot nicer, but agreed that you're not pulling 5hp on this thing over a charcoal delete.

I've been running Bimmerlabs mafless 330i tune for months now without any issues. I also have AA headers ready to go on once the new tune is ready to go

As for intakes, I swapped between a NA box w/ charcoal delete and a Euro box, both with new Mann paper filters, and didn't notice enough of a difference to justify spending any money.

[porsche959]

i added this little rice booster to a stock n52: https://www.mishimoto.com/bmw-e90-n5...oot-06-13.html

made the car reasonably louder.

the bright red/blue is a little heinous, but they also come in black.

I had asked the OP about his turner intake, his comments are below

me

3 stage intake, euro IAT, silicon boot, euro airbox, MILVS, AA headers (and 3.73 diff, the tune takes it into account for calculating which gear you're in)

I honestly don't think the airbox and elbow did anything, but it sure sounds good when I take the airbox cover off. Also extra euro scene points bro

Runs like a top. The biggest difference I noticed with the MAF delete was Rev matching/heeltoe. seems to Rev with more agility. Not sure how to describe it but if you're familiar with your car, and you switch to a IAT+correct tune you'll notice a new particular smoothness. Low speed driving is a little less hurky jerky. The argument is that the MAF can't accurately read air speed when the air is flowing slowly (say under 2000rpm) and perhaps it's getting restricted at higher speeds - massive cross sectional area.

Look at the difference between the MAF and IAT. Should start to make the picture clearer why we prefer it.

once the cruise is sorted I'll probably go with the IAT tune.
based on desertmans happiness.


thanks for the hacking.
