Can I get a better picture of that dyno graph?

Soccs · 10-13-2014, 11:51 AM

sure let me scan it

Soccs · 10-13-2014, 11:56 AM

here you go

Something's wrong in that setup. Got those figures with stock exhaust & headers running on 85 octane and a 30 degree ambient temps. None the less great setup, I like it

Agree on both.

TheSt|G · 10-13-2014, 01:12 PM

+1 to something being wrong. You are significantly down on both HP and torque compared to me, despite running a similar setup aside from being a 125i.

saw the curve on the graph..is it normal to see that dip on 4.5k rpm? cause it kind of was a bit ''out of place''

There are a few things that seem off about your graph-
Low end torque seems good, but with headers, the second DISA opening makes the most power - you can see on yours that's not the case.

The 2nd DISA opens at about 4500 (which is where you see that dip) BUT the power should immidiately rise after - yours doesn't, causing the last part of the power range to be lower than expected.

That's not my graph

I just noticed it and commented here.

Ahh, I wasn't paying attention. My bad.

andrey_gta · 10-13-2014, 05:18 PM

i too think the graph is less than stellar - either the Dyno is pessimistic and makes this look weak
or there is an issue with installation or tune

Soccs · 10-13-2014, 05:40 PM

I have sent all this info to Evolve. Lets see what they say.

Thank you so much for all the imput! I was definaly disapointed once I started driving the car.

Stage 2 is what Evolve calls the tune for n52 WITH the 3stage Disa Manifold added. Mostly for USA/Canada cars

MarkkyyMan · 10-13-2014, 10:58 PM

Probably primary 02 sensors starting to fail..

But some interesting facts about the 125i compared to the 128i... And I didn't know this... Is that, 125i only has 2 cats... Compared with the 128i having 4....

Where are the secondary cats? From top to bottom I see BMW PE (muffler), stock resonator (section 2), but nothing in section 1, where i thought the secondaries where. Can someone help me out? Thx.

What, in your own car?

Yes.

I know the pic is a 125i, but is it different in the 128i? I guess probably so, since emissions standards are likely very different...

Yeah seems like the 125i pic is different. The stock cats should be at the end just after the header section. If you look under your car, you can't miss it. It's in plain sight not covered by anything.

Thanks. I would've looked under my car by now, but I'm currently overseas.

Oh, you are looking at parts diagrams. I was trying to figure out how you managed to get a car in the US that doesn't have secondaries.
