Who here is running the NM Power Module? Are you running it on high or low setting?

I installed the module this week. There is definitely a night and day difference. In high the turbo is much more audible. That said I ran it on high for a few days and noticed some major lag from a dead stop while in the high setting (using 93 octane from a top tier station). There is a ton of torque down low however around 50mph it dies off quite a bit.

I switched it to low yesterday and the lag from a stop is noticeably reduced. The down low torque seems a little less however the car feels to pull harder all the way to 70mph where it feels like before it may have died off a bit.

Anyone else have similar/opposite experiences? Thanks in advance everyone.

 

I usually run mine on HIGH and have never had a problem and I've been using 92 or 93 octane gas. I've switched it to LOW now for the rainy season here in Seattle because I can very easily spin the tires on HIGH in wet conditions.

 

Thanks for the response. I have some low end knock under light acceleration when in normal mode on the HIGH setting. Switched to LOW and it appears to be gone. I'm going to run through this tank of gas and try high setting on next fillup.

 

I've been running mine on the high setting as advised by a NM tech. Running 93-94 octane and have never had a problem...... other than excessive tire spinning.

 

I think it was the gasoline. I filled up again today at a new station with the same 93 octane as last time and not a single issue. I enjoy how loud the BOV is now when in sport mode.

 

Well, smooth sailing only lasted a short while. High setting seems to be acting weird on my car. Max boost pressure is around 14psi. However when switching to the low setting on the module max boost pressure peaks at around 18psi. I am going to uninstall the unit tonight and measure stock A/F ratio's, boost PSI and timing to get a baseline idea of how it is supposed to be running without modification. Then the same with the low and then high settings on the module.

Does anyone know, is our waste gate spring operated or a module? Wonder if it is leaking due to too much pressure on the high setting. Just a guess since I don't know these cars that well yet. Worse case scenario I call and talk to the guys at NM and see if they might want to exchange it on the off chance that it is not working correctly. I did message the guys over at ECS a few days ago (where I bought it from), no answer yet though.

 

18psi? I thought stock F56S runs at around 6.5- 8psi? You should be at 13psi at the most.

 

The mode of measurement is not the most reliable, a wifi obdII adapter. That said I just got back from an hour or driving about half the time in each mode. Peak PSI was 14 for both modes however the Low setting was peaking at 14 more often.

I am going to try and talk to Jerry from NM in the morning.

 

Well the NM instructions say that the High setting is only for 100 octane, soooooo, it can't be a huge surprise that the ECU is going into a reduced-power mode when you're only running 93 octane.

 

Fair enough, however I think it has been stated a few times in other threads that NM has confirmed that 93 octane is OK with the high setting if not being used in long WOT situations (like a track day). The dyno chart NM posts on their site shows they ran 91 octane in high and low settings.

Either way we are talking 2PSI difference between the settings. Low=3PSI additional and High=5PSI additional boost. I have not had any engine lights or the limp mode I believe you are describing.

There are also a few other members here who are running on high with apparently no issues. What setting are you running it on?

 

Did you send me a PM ? I dont see one sent.

 

I actually sent it through the ECS website. I am using a new phone though so chances are I messed something up. No worries, I called NM yesterday and Jerry is going to give me a call today to help get it sorted out.

 

ok, just wanted to make sure, I will contact our sales team to see if one came through at that gmail.

 

Well I had the pleasure of speaking with Jerry from NM this morning. SUPER COOL guy by the way. After discussing in detail about the different setting and boost readings we confirmed either my car has something mechanically wrong or the box is not performing as it is supposed to.

He is going to take a unit off the shelf and test it on his car first and confirm it is working properly. We are going to exchange the boxes, once I have the new one installed I will test it and follow back up.

For future reference if you are in the low setting you should be seeing peak PSI around 18,high setting can peak at 20-21PSI. It appears the low setting on my unit is working as it should and either my car is having an issue with the high setting, or the NM box is not working as it should on the high setting. Should know more in a week or so and will report back.

Can't say enough nice things about the NM team, super friendly and willing to help. I am a loyal customer from here on out.

 

Rob, thanks for confirming the peak boost numbers with NM. I hope you'll get your problem all sorted out ASAP.

 

I thought with these "piggyback" style modules, the idea is that the manifold pressure sensor signal is intercepted and effectively scaled down such that the stock ECU is never aware that actual pressures are higher than the stock software calls for?
In other words, I would expect an OBDII monitor to never show higher than stock pressure? I could be totally wrong..

 

From NM website:

OBDII displays actual boost and not compensated, which makes the module compatible with all OBD reader/scanner, such as: Scan Gauge, P3, PLX, Torque Pro, etc

 

Informative, thanks for posting! I'm running on high and have yet to use it in the low setting. I have to take my car in for service soon, so I might just switch it up to see.

 

Does the installation of the power module affect the vehicle warranty?

 

Depends, to be safe, remove it prior to having engine work done. If they really wanted to be difficult, the dealership can say root cause of X problem is due to aftermarket item X, not being approved aftermarket items from MINI/JCW.

 

I'm sorry I'm a little late here but I thought this was standard too? How are you reading 14-18psi?
