Check out my update in the thread referenced above. I don't believe for a moment that my issues have anything to do with the MILV's.

lol I think y'all misunderstood me. I'm not saying the MILVS are faulty. I'm saying that they result in extra TQ, and that extra TQ could be what is causing your issues. Therefore the MILVS could be indirectly causing the problem. But that's exactly what they're designed to do! We just need the tuners to figure out how to adjust these TQ overflow values so that we can stop being put into limp mode due to all of our newfound TQ (partially in part to the MILVS). Get it? I know that not everyone with MILVS is having issues. Just like not everyone with an AA tune is having issues. But either way, there are issues being reported by people who have mods/tunes that result in "significant" TQ increases. Therefore I personally feel that it is appropriate to have information regarding these issues in the MILVS thread, because MILVS seem to be one of the greatest power adders we've found, thus some-what likely to cause issues with the cars until the tuners work out how to properly harness the added TQ/power.

But either way, it's not JUST a MILVS problem, obviously. Some have reported tune issues without MILVS. Plus, you and the other guy dealing with headaches currently both have other fishy things going on re: 3 stage intake manis, etc.. that could also be causing your particular issues.

All that said, it's now starting to seem like these limp mode issues, at least with BPC tunes, are caused by completely unrelated mods.. which is good to hear!

That's what it's looking like...

I read somewhere where if one of the rear wheel sensors is faulty, this will cause a 'bigger' difference between left and right wheel speed, like doing a 1 wheel burnout/tire spin, and this is interpreted as too much torque and goes into limp mode. The faulty sensor would cause it to think it is doing a 'burnout' for a long distance which could be 'over TQ'.

IDK, just throwing this out there. That is how the ABS works.

[hassmaschine]

yeah, but that error would show up in the DSC system - not the DME.

We dyno tuned E90Cruisin's N52 yesterday with the MILVs. I'll let him post the chart, but the car made 208whp with the 3im, euro intake, catless headers and MILVs on the stock tune and 238whp when we were done at the end of the day. Using the latest version of our "non-MILV" tune it made 229whp.

[CobraMarty]

SWEET!! ActiveAutowerke tunes for MILVs!!

208whp No AA Tune (stock tune) with catless headers, 3IM, EURO and MILVs
Obviously not taking advantage of the 3IM especially which needs to be 'turned on'.

229whp (+21whp) with Latest Version AA 'non-MILV tune'. I'm sure that the MILVs added a few of those ponies even without the specific MILV tune.

238whp (+9whp) with AA specific MILVs tune + catless headers, 3IM and EURO.
That is right in line with what to expect with the MILVs and a specific MILV tune, +9-12whp.

This just shows the importance of your tune/tuner knowing exactly what you have added/modified on your car and how they can maximize the power output of all the added parts.

Dyno or it didn't happen.

According to my napkin math, your dyno (Mustang) reads approximately 8-10% lower than a Dynojet (I say 10 - but it varies)

Baseline: 225-229whp
Dynotune: 247-252whp
Dynotune + MILV: 257-262whp

I don't know why tuners just don't keep the dynotune on file and use that as a basis for all tunes.

[tom.gnade]

I would love to see the dyno, please post!

He has the chart, if he doesn't decide to post it I'll edit out his personal info from the chart and post it.

The 229whp was with the MILVs, but using the same file that was created from dyno tuning our 328i shop car that had all of the same mods except for the MILVs. It was not a custom tune by any means, it was used as our base tune for the 238whp file. It's the same file that we send out to customers who purchase an N52 tune.

The 238whp file was after dyno tuning the car with the MILVs.

Three questions for everyone here:

1. will this new dyno tune file be what they are getting
2. did you find a way around the torque limiter
3. Not really a question, just a compliment - good work

1. If you order a tune and have MILVs, this is what you'll be getting.
2. I'll have to confirm with Nic exactly what was done and get back to you (he's not in today).
3. Thanks

Is the car a 328i/xi? His sig says 330i.

E90cruisin Can you confirm? And post dyno results?

[F31cruisin]

Hi everyone,

So the car is a 330i, so it was already tuned for the 3IM technically. The car has a silicone elbow, euro intake box with K&N cone filter, intake scoops, ceramic coated super sprint headers, and MILV's.

208whp No AA Tune (stock tune) with catless headers, 3IM, EURO, elbow, scoops and MILVs

229whp (+21whp) with Latest Version AA 'non-MILV tune'.

238whp (+9whp) with AA specific MILVs tune + catless headers, 3IM, EURO elbow and scoops.

After the day of tuning, the tuner left a believer in MILV's. Car is still adapting, and feels super strong at the moment, with slight idle stutter sometimes, though it is getting better each time I drive it. Chart below.

Will AA be able to update current tunes to MILV tune for a certain price?

ugh. Ok why did the dyno operator shut her down so early on the baseline run?? Who knows what the peak HP is with the stock 330 tune because the operator let off throttle at 6000 RPM! And clearly the car/tune/3IM can make power past there based upon the other plots. Via mentally extending the line from the stock tune run, I'm estimating at least ~215 whp with stock tune and those mods, NOT 208 whp. Perhaps the whole project was around MILVS and the operator/owner didn't care about the power without tune, but for those of us wondering exactly what kind of peak gains an AA tune will getcha, I'm seeing about ~13 whp (not 21) based upon this particular example.

Either way, yup, ~10 whp from MILVS. Lookin good.

So, in summary:

330i (or ~ 328i + 3IM + BimmerLabs Tune) + Catless Headers, MILVS, and Intake = ~ 215 whp [?? whp gain from Stock 330i Configuration]

330i (or ~ 328i + 3IM + BimmerLabs Tune) + Catless Headers, MILVS, and Intake + AA Non-MILVS Tune = ~ 229 whp [14 whp gain resulting from AA 'Non-MILVS' Tune]

330i (or ~ 328i + 3IM + BimmerLabs Tune) + Catless Headers, MILVS, and Intake + AA MILVS Tune = ~ 238 whp [9 whp gain resulting from Dyno-Tuning for MILVS specifically, Total 23 whp gain resulting from Tuning]

I also find it interesting that both AA tunes result in a loss of HP and TQ in the lower RPMs, especially w/ the initial off the shelf tune.

Regardless, great numbers and N52 looking strong.

Yes, stock exhaust and stock secondary cats. Car is quiet when cruising, and opens up over 3000 rpm’s. It is perfect

We didn't lift off of the throttle early. The car actually started losing power above 6000. We use a loaded Mustang dyno so the results are a bit different than dynos that rely only on roller weight. We've also noticed that the initial torque reading varies based on how you initially apply the throttle. On the street the car feels like it has more power and torque everywhere.

[Taskmaster]

There is a possible 10whp+ hiding in that exhaust system.
