I also have a comparison in Sport + mode which shows the same thing, I'll post it in a bit.

Ohhh okay, so there is a difference in mapping between comfort and sport+ ?


I still haven’t installed my MILVs yet, I haven’t even actually tuned my car yet. I’ve been kinda waiting to see your results haha.

Who and what are you tuning with?

Here is another comparison, both run in SPORT:

Pre MILVS, FBO, MPPK intake, MST Inlet, Downpipe, craptastic intercooler, M Performance "exhaust" Stage FP OTS Tune
https://datazap.me/u/amuroray/3rd-4th?log=0&data=2-3-19

vs

POST MILVS, FBO including CTS intake, MST inlet, Downpipe, VRSF Race intercooler, M Performance "exhaust" Stage FP OTS Tune
https://datazap.me/u/amuroray/milvs-...30-31-32-33-35

Biggest delta recorded 19.5psi @ 5800 vs 17.8psi - 1.7psi

Don't worry too much about the differences in WGDC - those are reflective of the intercooler change more than anything (more internal restriction vs the crappy core I took off) but you're notice the car is more efficient. If you're on the fence, there really isn't a downside. You'll need and want a tune to remap the Valvetronic curve (I'll do a comparison of that next) and adjust the boost accordingly, which as you can see, is reduced a bit.

I think I want to try BM3, I pervously had MHD on my 435i and it was good, but after reading the majority of F87source’s in depth post on BM3 I think I want to give that a shot. I’ll most likely have Bob do a custom tune once the MILVs are in because he’s the OG with tuning for them.

I think I asked before, but is there more room in your tune to maximize those MILVs?
I’m personally torn on deciding if it’s worth it to squeeze every little bit of juice out of the stock turbo or move to something like the Shuenk N55+ turbo and have a healthy 400 whp car on 93 octane.

100% more room, currently working on that…

Choke - understatement rer oem midpipe.

Hence adding supersprint front pipe between Fspeed DP and OEM MP exhaust.

Full bore incl larger ID flex jt, albeit not 3.5". Upsizing DP outlet to suit 3.5" midpipe - good option

[AmuroRay]

I was doing a full dyno tune today and I had an injector fail. Do I need 1 or all 6?

Just an fyi…talk to local fabricator. They can likely make something better for a lil more $$$. Im doing a custom dp—midpipe that ties into mperformance muffler. 3.5” dp opening and midpipe

Depends on budget really…Im replacing all mine soon and will have spares i can ship. Similar to coils..replace the faulty one or be preventative and do all 6..

Have a good place to get them? I was going to check FCP and RockAuto, or maybe even EuroKlasse (where I got actual S55 Coilpacks)

Im replacing mine with s63 injectors. Got them from Dorche. Seem to be same price as n55's...make sure you get new couplers. Since I'm swapping mine out, I can sell you my n55 ones. Just depends how quick you need them. Goes in the shop next week.

I might take you up on it, I'm going to check the plug really quick and also the PNs on the injectors to see what kind they are. I have a few in my cart already.

What a waste of a day, I I'm on my 3rd revision and I can't even test it.

[AmuroRay]

I've basically taken this thread over, I should probably make my own at this point.

I replaced the injector and the spark plugs with the same version (NGKs) with the stock gap out of the box. The plugs I had before were the same, with likely less than 20K on them, but since I was there and FCP has a free lifetime replacement....you know.


Here is a quick test of the revision last I was running before my injector gave out on the dyno, some quick observations:

53F outside, the intercooler was basically 4-8F ambient for the first 3 runs (very first run was 2-4F over ambient)

Not sure if I should have gapped the plugs, but I notice that my timing isn't as clean. The last time I didn't install the plugs myself, so I'm unsure of if the shop gapped them.

Fuel is Costco 93

MAF Reading is actually quite a bit higher than before at the same boost level, but I'm not sure how. This was consistent between the runs and versus my previous runs.

Power is "down" because I'm running less timing right now

[AmuroRay]

It's been 4-5 months? Bob sent me a few revisions - I ended up losing an injector, fixing it and losing another - and replacing them all. I replaced the plugs with new NGKs, but the the timing is "meh at best" and was actually cleaner on the old NGK plugs (.030-.031 gap) and a 3.5MAP.

Unfortunately, I have a boost leak at the inlet, which has caused an air intake fault (just had a friend over today to smoke test it) so that issue, combined with the previous issue with the injectors and the MAP maxing out issue and now unemployment (whop whop whop) mean that progress has been slow. No worries, I'm glad to know what the issue is and I hope to have it sorted by this weekend.

Of the tunes sent, my favorite tune is Revision 2.5 which I will attach here as not the final tune - Bob at StageFP really did a fantastic job here. I know that ericlr1225 says that "Load won't lie" so the tune has increased the load substantially - I'm sure it's over 400whp now (and one calculation put it over 420whp...but let's relax on hypotheticals until I have a dyno)

I was doing some reading on how load was calculated, and saw some posts from wheela years ago on the E90 side, so maybe he can give some thoughts on what I'm seeing.

Revision 2.5:
https://datazap.me/u/amuroray/tune-r...og=1&data=4-23

Standard Tune:
https://datazap.me/u/amuroray/evenin...30-31-32-33-56

RPM | Standard Tune Load ( Ram) | Rev 2.5 Load (RAM) |
5500| 181.6 |
5600| 182.7 | 194.8
5700| 183.1 | 194.3
5800| 183.4 | 192.9
5900| 179.4 | 191.1
6000| 177.2 | 188.1
6100| 174.0 | 183.7
6200| 171.0 | 180.0
6300| 170.8 | 177.2

Peak MAF flow:
346.1g/s at 6180RPM Vs 367.3g/s at 6082RPM

Sorry, is the standard tune with the MILVs installed or not?

Are you planning on doing a comparison where there the only difference is the milvs? same tune?

I ask because I can manufacture these but have taken them off the site after a video came out saying they did not make a difference. If they do, I'd love to provide them for the community again.

Nothing personal, but I know Marty, and know the work he put in. I was one of the first costumers who bought the original units with .5mm of lift, and sent them straight to Bob (StageFP) to test in his shop 330i N52zI bought the second set 1mm for my car after the tune was developed. I respect him and his work, so I can’t endorse anyone copying it, especially because I’ve seen that the counterfeits being sold don’t work at all.

Do they work? Yes. But the N55 head doesn’t flow as well as N52. They do allow
More power to be carried in the higher RPM region, and are about 30 mins to install with the VC off.

This tune isn’t even the final version - I have ze that are even hotter than this, but still waiting to test them once the car is fixed .

I respect how you feel, but they aren’t counterfeits, and the only reason I made them was because people were asking me to due to the demand and their inability to get them. A counterfeit would be if he had a brand and someone were claiming they were his brand. Either way, here is what I was referring to regarding the claim that they don’t work. Maybe you could give your 2 cents on it. Sorry if this has already been addressed in this thread. I want them to work, I work on all sorts of N5x motors and it would be sweet. Where is this guy’s logic wrong?

He bought counterfeits from some guy selling them in Europe. Marty was out of stock and some guy managed to capitalize on the shortage by selling counterfeits. We had a thread on iron the E90 side.

On my car, the caus r the car to lose boost as a result of the increased airflow, as much as 1 - 2psi? I believe. The car will need to have the valvetronic map recalibrated based on the new lift curve (this was something Marty tested on the bench and mapped out) so your tuner will need to update the maps to increase total lift AND lift at specific points, because of course the DME is looking specific values at specific throttle/RpM, Load - etc. So just piping them in likely won’t yeilf anything without a tune that can capitalize them.

Ahhh! So this guy bout fake MILVs or stock passed off as modified? Did he ever look at or try the real thing? Regardless, he point is the geometry would be wrong.

I’m watching it now - his original post in his Facebook page was about how they didn’t work, and I think was forced to pull it down because so many people pointed out how they did and he bought counterfeits.

You can see the conversation here along with refuting what he’s saying about it not increasing valve lift. When Marty had the head on a bench and was testing it, he did note that because there was no oil pressure (and sorry, this was around 2018, so I’m not 100% on specifics) that the cam lift did not read the correctly.

6you can check this thread out and I’ll see if I can find the original testing of it in 2018

I dont see anything wrong with Bruno’s testing. It’s thorough and explained, he had been in contact with Marty throughout he had said. Is Bruno a neutral party? I’m not sure about that, but I can’t pick any holes with the process he shows in the video.

I have bought (Marty’s) MILVs and the top end did feel slightly stronger on the butt dyno, but I have no actual quantitative data to share. The only other noteworthy thing changed when the MILVs were installed on my N55 was a clutch and flywheel, so a fairly good back to back. I have since removed the MILVs though.
