Question "Anniversary" Log Review? - 09-10-2019, 02:08 PM

Ran a log around a year ago, shortly after acquiring the car. Just ran it again (in the same spot), same specs, same JB4 map, etc, seems like not putting out as much boost. I have inherited the wastegate rattle since then for what it's worth.

2007 BMW 335i, N54, E90, Sedan, Manual Transmission, Sport Package with Oil Cooler. Running on 93 Octane. It already had most of the normal mods done to it when I purchased:

- ctless downpips
- BMS DCI
- Upgraded Chargepipe, BOV
- Upgraded Intercooler (5" I believe)

Using JB4 with Bluetooth kit and MHD backend flash. I usually run Map 2.

Test was 3rd gear, WOT, traction control off, 2k to redline, tire pressures at proper rating, oil topped off, clear skies, dry pavement, moderate downhill incline for first half and slight uphill include for last half of run. I included the graphs from last year's run and today's run (files named with the dates) for reference.


- How does my current log look?
- Any thoughts when comparing my previous log vs the current one?
- If I run 3-4 gallons of E85 (so E30 I think?), would I notice any power increase on Map 2? Or would I have to be in Map 5?
- Would I notice any increase on straight 93 octane being in Map 5 over Map 2?


Thanks in advance!

Your lpfp is in the 40ís.. probably should replace or upgrade ASAP.

Question 09-10-2019, 02:19 PM

Thanks for the quick reply!

My low last year was 47, today was 41 - what do you think would contribute to the drop? Just age/wear, or is there another factor? The set up between the two runs should be nearly identical.

And, do you think that is what is directly impacting my lower boost numbers?

Any other points to note?

If itís the original lpfp itís probably just wore out. Yes itís impacting your boost and I would stay on map 1 until you upgrade. You definitely shouldnít run any E85 with that pump imo. You can run e30-e40 on a stock lpfp if itís healthy but yours is weak. I would upgrade to a stage 2 lpfp and then you donít have to worry. My point is youíre in the 40ís on pump gas.. not good.

Question 09-10-2019, 05:41 PM

Totally makes sense, thanks for the advice!

Do you think the wastegate rattle is a symptom of turbos performing subpar? Can you tell that from the logs? Sorry, somewhat of a newb here

Anything else in the logs look telling/bad/of note? What about hpfp?

Thanks!

Question 09-10-2019, 05:43 PM

Oh, and I'm at ~145,500 miles on the clock - originals fuel pumps, turbos, engine as far as I'm aware. Other than wastegate rattle and what you mentioned about lpfp, she seems to run strong with no leaks to note (I add a quart of oil every 1000-1500 miles or so, when the +1 indicator shows), and try to do oil changes every 3000-4000 miles

How many miles are on your car?

It looks like it takes awhile to build up boost.. your turbos just might be weak and worn?

Question 09-10-2019, 05:54 PM

No worries; I realized I hadn't included that helpful piece of info before you asked

When I got it right at a year ago (1 year this Friday!), the bolt ons had already been done, and all the places where oil normally leaks had the gaskets replaced, and it didn't have any wastegate rattle. But, it had an unknown tune/flash on it and was putting out ~18-19 psi boost. So I had the JB4 with bluetooth kit installed by a local performance shop that specializes in the N54/N55 engines (it's almost all they do), and did the MHD flash to go with it. I didn't feel comfortable running that boost without even knowing what tune was on it.


Just replacing the lpfp, do you think I'll see a noticeable power difference on the ol' butt dyno? And anything telling about the hpfp from the logs?


I'm also curious if the turbos were new (not upgraded, but just replaced with stock new ones), what the performance difference would feel like. Just curious how much the wear has eroded the turbo performance.

If it's helpful, I have gotten the 30FC "Exhaust Fume Turbocharger, Density" code popped up a couple times this year; usually under heavy acceleration, and maybe once every couple of months

This is just my opinion. Yes you can get more power by upgrading to a stage 2 lpfp and adding some E85 however your turbos might be a little tired. I wouldnít run anything but map 1 or stock map 4 until you figure out if they need to be replaced. If they are original with 145,000 miles they probably at the end.

LPFP appears to be extreeeemely tired...

I'd replace / or upgrade asap : FUEL PUMPS - FUEL PUMPS - FUEL-IT!

Turbos do appear to be a little laggy, not shocking given the mileage
