This is why I run fuel system cleaner yearly in an effort to keep everything clean.

Wait are you sure Bob is talking about the recent BM3 table editor update? Because I just checked and they absolutely are there - 10 tables related to the eccentric shaft specifically and 3 tables for application mode. So 13 tables related to valve lift specifically. The related tables are there too and if you open that tab, then there are hundreds of other tables to modify. So I am pretty sure that statement that BM3 was missing tables was from a long time ago when they first started, because my m2 has 5,158 available tables to modify.


Here's an image (but alot of the tables are overlapped and covered up, but you can see in the pull down bar on the left the number of relevant tables there are, and note some of these 3D tables are massive and fall off screen):



If indeed some tables are missing then I'm sure your tuner could talk to Dzenan from BM3 and he would have it added, otherwise you can now use any table editor you want and define your own tables via the DAMOS and an XDF file just like you would with MHD. This means you would be able to access some 50k tables on the ecu (most of which are unrelated to tuning but more for sensor calibration), so this issue shouldn't be relevant anymore.

AmuroRay what's your plan for the injectors? just clean the tips?

Just cleaning them. No big turbos, or likely E85 here. I do have an upgraded HPFP though.

We are getting close - Part of me wishes I grabbed a TIC pipe and wrapped that as well as selectively wrapping parts of the intercooler itself. The reflective tape will hopefully keep IAT's down further.
He said he cut off an inch of it on each side of the charge pipe to make sure it sealed correctly.

Did your tuner have to adjuster the boost at all? Is the WGDC any different after install? Bob told me the same about BM3 and the lift tables, they aren't there.

On the N52 turbo car - the MIVLS were good for 23whp at peak and deltas over 35whp. Of course, the N52 is a bit different, including a better flowing head and turbo,

Believe it or not installing the milvs I “lost boost” due to the car being more efficient. Thus turner the boost back up slightly to maintain torque throughout. Was peaking 24-25 at the time, after the install car was happy at 22 at peak to red line as torque and load was calculated to be achieved. I needed to have fuel added (expected with more lift) to the tune overall.

I’ll be on the dyno within the next two weeks to officially have 93 + all the mods in my sig on a dynojet. Just trying to clean up sim random boost control/PID settings (causing a small throttle closure at the moment) before I spend time on the rollers.

Aiming for 340whp+ on 93, and I hope to cross 390whp on e85.

Not to derail your thread. But I did make 373 on 23psi with full e85, thus I believe my goal is achievable but we will see. Check my post history for the thread + post.

Not my thread, OUR thread - and interested in hearing about your experiences. I was checking your build a day ago, and it's awesome.

Do you have the before and after logs for me to look at? Have you tried plugging it into virtual dyno?

Yup you're supposed to lose boost. Because the intake valves are open longer allowing more air to get in thereby dropping boost. This is actually a good thing because boost is just a result of air backing up and "waiting" to get into the combustion chamber, and it's technically unwanted. You want as much air to get in as possible without backing up, aka lower the flow restriction and limitations.

I know it's a different turbo and flow rate, but the difference between 25PSI and 22PSI is about 12% - does that mean he's making 12% more torque?

What would that mean for us?

It's not going to be a percent for percent comparison due to drove troan losses etc. But he should be making more power with less boost. This means an improvement in the efficiency of the car, and lower iats as a result.

So it's not saying it'll be 12% more torque per say, but it's that he will be making more power and torque with less boost.

This was expected but not 3psi. I figured 1-2 but for my motor it was that drastic. I have yet to drive the car with the VVT settings adopting the milvs and full e85. Car does feel as if it has the torque the car did on e85 so that’s going to be a nice change.

Logs are too far apart for a before after comparison, didn’t actually log/dyno the car on 93ISH (e25 but with 93 trims) as our local 93 has been so inconsistent that e25 mix keeps things clean. Can do a comparison of full e85 to full e85 after milvs within the next 2 months or so

It's free, just plug data about your car in, upload your log and it can give you a comparison. It was pretty close for me.

I think he did - because whoever did it before (not me) cracked the spark plug well, which is why we had to add a few days on the project while the parts came in.

It will be a few more, because I ordered the AGA brake cable fix to be put on with the Midpipe for the exhaust. Super Sprint and AWE say the mid pipe is worth 10whp on its own - M and non M…

Interesting, because cracked plugs are typically a sign that there is a lot of stress during install which could very well be due to not using a swivel joint.

I kind of find it hard to believe that a mid pipe can bring 10 whp on its own but ok.


Keep us posted with the results though!

Not plugs, the wells.

Yup that too, but generally it doesn't completely break the well, it'll scar it and scratch it. I can't even believe it broke - because that's a lot of force.

I think the torque number (fairly off) and whp is off slightly (in estimating 10whp) but it’s close enough to the n20 for peak power generation anyway.

352 whp at 5676 rpm
386 wtq at 4000 rpm

Mind you this was a 3800-7000 rpm 4th gear log, e25 in the tank with 93 fuel/timing trims.
