It's common in the UK to convert WHP to estimated BHP using a guestimated correction factor. However it's still useful to see what potential gains something has as long as you have a baseline with the same conditions.

Thats still quite a bit. Im really curious to see how much i have but i dont feel its worth it since its so slow

Just to clarify, I found the thread where he claimed the SAE numbers were about 217whp.

Graph:

The dyno graph says that power is on the flywheel (or basically at the clutch - "kupplung" is coupling/clutch)

So it has 258ps at the flywheel.

@theaxiom may you add that I have no tune.

Route 16 · 10-17-2014, 11:11 PM

WTF happened?
From Jan'14 to Oct'14, 10 HP decrease difference? It's the same set up kind of. Jan'14, magnaflow muffler with 2ndary cats still in, dual exhaust conversion, cold weather 60's outside temp, 19" wheels, about 23 lbs, dirty K&N filter cone intake.
Oct'14, no muffler, 2ndary cat delete, quad exhaust conversion but it's still the same exhaust direction as the dual, mid 70's outside temp, 18" wheels, about 18-19 lbs, brand new Green Filter USA cone intake.
Same mustang dyno. I'll be optimistic, at least I know what the low numbers are.
If any tuner (ESS/Active) were to look at my sheets. Can they play with it and make adjustments to my stock tune?

Yeah the afr looks wacky. It looks like its not hitting the full load map until 4500 rpm, then it goes pig rich.

I assume thats a 328i?

Yes
Since i know nothing about modifying a tune. What will happen once its corrected?

hassmaschine · 10-30-2014, 01:05 PM

it looks to me like he's not triggering the full load threshold. I've seen that before - it starts out wicked lean and then it goes wicked rich because the DME tries to compensate.

yeah, I got enough data points that next time I'll be armed with a bunch of different files to try, rather than making changes on the go (tuning an OEM computer is slowwww compared to standalones). Also, I think I figured out what cuts off the engine at ~6800rpm but I can't really verify until I go back to the dyno, which will probably be next spring.

I don't know if I want to do headers in this car. I think I want to do an N52 in another car, I've got some ideas..

hassmaschine · 11-24-2014, 03:54 PM

heh, yeah, into my E30.

I know hoveringuy in person. actually, last time I was at that dyno we were working on my car and his M54 swap. He did say exhaust vanos didn't do much, I agree it probably needs headers. I was playing with cam timing with a mechanical adjuster and wrenches, he was doing it with a laptop.. that sort of lead me to where I'm at now.

you can modify the load/rpm transitions, yes. but seeing how those are mostly harmonics, I'm not sure there's much to improve, although I haven't tried.

His name is "Steve" right? Dude has done some baller work, more than I can accomplish. He did tune his M54 to not have a DISA transition dip at all, which was pretty impressive, though it has a lot to do with Megasquirt.

The DISA is completely harmonic driven, but I imagine they change when there is a significant change in airflow. I hear that function is not available with the MSV80.

When you say 'cuts off the engine at 6800' are you talking about the so called soft rev limiter that seems to pull a bit of timing before the hard rev limiter at 7200 (or was the 330i 7000 originally, I've had a tune for a while).

hassmaschine · 11-28-2014, 11:52 AM

I'm talking about the soft limiter. the stock limiter is ~6900, but the soft limiter seems to start kicking in a bit sooner. the soft limiter is weaksauce.
