Idle is horrible. Full e85 port injection fbo n55, has been this way for a long time long before full e85. Any ideas on what it could be?

Crazy wastegate rattle, boost seems to lag and doesn't really come on till 3500rpm, turbo's are 6 months old, No 30FF, car is running MHD stage 1, DCI's

Austins · 06-01-2019, 07:12 AM

Had a few runs the other night, new stock turbos (2 months old) and getting 30ff....
Only think i can think is stock dvs

Any ideas haha (or anything else you see wrong in the log?

Hello,

I did logs yesterday to check if everything is ok with new turbos installed. (OEM Mitsubishis)

N54 135i with 64k miles

Log is a full 3rd to 4th pull
(wasn't the first pulls)

Map : MHD Stage 2+ V7 on 91 fuel (95 RON)

Mods list :

ER Chargepipe
Forge DV
Wagner DP
Forge FMIC (using OEM factory c-clips connectors)
BMC Drop-in

Ambient temp was 63°F (17°C)

I am bit concerned with the Forge FMIC, the IAT raise from 75°F to 104°F at the end of the 4th gear.
(It's not as flat as some people log i've seen with other FMIC like VRSF)
It is ok ?

I am really not an expert about log reading, maybe there are any other concern ??

Thanks

Logs look great! Your IAT's look good as well. They climb to 104 but that is not bad. I bet after the pull they sat in the 90's so it might have been low when you first started the pull.

Thank you for watching my log

Yes, after looking numerous logs to compare IAT, Forge FMIC IAT seems correct because it's a full pull 3rd and 4th log. (IAT rises a lot in 4th gear after 5800 rpm on our engines, even with an aftermarket FMIC)

More over lots of FMIC logs are based on 1 single gear pull.

Any idea what is wrong with my start up roar? Seems like it tries but doesn't quite get it. This is a custom map

johnscales · 06-06-2019, 06:38 PM

Taking one for the team.
Since we in the UK have little to no easy access to ethanol i've bought the E85 mix maps for my car to mix with methanol. I know I know Don't do it I hear everyone cry. The fueling is constantly made for ethanol so when not running boost you'll be harming the car. I hear the derision and (possibly as a result) can't find any logs of anyone trying it. I myself was told try it log it and if the car's happy then fine (source shall remain nameless).
So onwards. My car my risk.
Trialing the e25 very conservative map.
I've a couple of logs which with my limited knowledge I believe don't look as though the engine is about to blow. In fact the only issue I see is STFT pulling fuel massively. What gives? I thought that ethanol required more fuel and that Methanol wouldn't be able to spray enough (or is it increase the octane enough) to meet the requirements, yet the ecu is pulling fuel. to the tune of nearly 34%?
My afr's fall in line with targets stated by the MHD user manual.
Timing correction is minimal during the pull and both fuel pumps are happy.
Virtual Dyno shows 410whp vs 386 my best FBO numbers so power is up.
Anyone care to comment on my log and also explain to me the STFT conundrum? I just can't get my head around it yet.
Could I even push a higher e mix? or is there something in the log warning not to do it?
Your experience is welcomed.

looks like your fuel trims are maxed out, you are also pulling timing at around 5000 rpm on 2, 4 and 5. I would be careful experimenting but have the mindset of a pioneer in the sense that you are discovering a new land. I would be more analytical about this as well. See how much octane you need to get to the octane rating of e25 and try to match that as closely as possible in the mix

johnscales · 06-06-2019, 07:08 PM

Thanks Chris1337. Those pulls around the 5000 mark are consistent with a few of the maps which aren't certified as being meth intended. They don't always occur. Maybe one in three runs. They're consistent in that they happen at the end of the run after a gear change. I had the same when I ran the 95/102 map with meth. Definitely being cautious hence the need for more input like yours. Still wanting to know anyone can advise on the possibilities behind the very rich mixture.

Probably running rich because the ecu is trying to protect the engine. I'm not a very good chemist so I couldn't tell you how rich methanol is as a fuel but I think your next step is to see if anyone on another platform has tried this

johnscales · 06-07-2019, 06:45 AM

I might just rethink this test. Found some info on a thread where the question was asked 'Can I run gasoline with an e85 tune'

"would I recommend it? Nope. So much Nope.

Why? - it's possibly okay because you are adding so much more fuel than you need by using gasoline that the car would probably not knock...

But it may backfire as you would be running it SSUUUPER rich -> till it went into closed loop fueling while cruising.. then it may make it a tad less rich, but usually those correction tables only allow for ~5% fuel adjustment, not 20%...

with the fuel being that rich you will risk damaging your

*catalytic converter due to flooding with fuel *washing the cylinder walls decreasing lubrication *detonation in the exhaust due to excess fuel *poor acceleration / power due to an extremely slow burn rate due to the richness of the fuel *quick fouling of spark plugs

etc etc.

So unless it is an emergency situation to get it just down the road to get more E85. No."

So adding meth possibly makes things worse (i.e even richer)?
Would explain my high negative STFT numbers.

I'll have to look, i've never seen anything with that name.

Do you mean cold start delete? I have that on mine and its fine. Keeps the car from being so damn loud in the morning or after work.

Nothing I hate more than a car starting up and being loud for no reason before settling to an idle.

It's an option for N55 only I believe. Supposed to be the opposite of cold start delete I think, where your car starts and makes a big roar when it does, at least that's what I got when searching for startup roar and MHD.

https://datazap.me/u/shadowise/rough-idle

Trying to figure out why I'm getting such a rough idle, if anyone please has any ideas what to check? 2011 335is 50k miles: fmic and chargepipe upgraded. No tune.

I replaced spark plugs and ignition coils without any improvement. I pulled the plugs after letting the car rest for ~8 hours and couldn't see or smell any fuel on them. Not sure how else to check if it's leaky injectors.

I noticed a large amount of timing corrections on cyl 1 during idle and the pull. After letting off the throttle I see that afr for bank 1 doesn't stay pegged that's why I was thinking leaky injector/s. Probably going to take is in to a shop in the Milwaukee area since I haven't been able to diagnose the issue.

Weven335 · 06-08-2019, 11:07 PM

So, I'm here to see if I can get some help with my car. Recently at WOT, my car has a very slight hesitation, kind of feel like it lurks, BUT I dont have any shadow codes or ses codes.

Vehicle Info:

2007 BMW 335i E92 N54
Chassis has 144.4k Miles
New Motor has 66.3k miles

Here is a list of EVERYTHING maintenance wise that has been replaced, upgraded or taken care of.

Index 12 Injectors Coded <5k miles
HPFP <1k miles
Vader Solutions Stage 2 <200 miles
Fuel Sensors LPFP/HPFP <3k miles
MSD80 to MSD81 upgraded and coded by Levan in SoCal (Due to MSD80 DME Failure on Highway)
Plug and Coils <4k miles
Oil change every 2k miles
Walnut Blast done <4k miles
Compression Test PASSED
Boost Leak Test PASSED

Current performance mods are

Pure Stage 1 Turbos <5k miles
VRSF Inlets w/ stock outlets
ARM FMIC
ARM Chargepipe with Turbosmart BOV
VRSF Kittenless DPs
MHD with JB4 Backend

Attached is a 3rd to 4th gear pull and noticed the slight hesitation. I'm not a tuner and I have no idea how to read a Log /: so any help is very much appreciated.

With the log that you listed I don't see anything but you should set timing as one of the items to log.
I hope you have a custom tuner? If not, you should get one.

Hey I have been having problems hitting target boost for a while now. so far i have done several boost leak checks, replaced the DV for a GFB and checked the vacuum lines i could get to. Does anyone think a boost solenoid could cause boost to react this way? here is a log thanks.

Log has 2 WOT runs both in 3rd with DSC off, first one was uphill. https://datazap.me/u/erzenble/run-af...71&tmax=100.90

Also does my WGDC indicate any sort of leak? thanks again.

Does anyone think a boost solenoid could cause boost to react this way? here is a log thanks. Log has 2 WOT runs both in 3rd with DSC off, first one was uphill. https://datazap.me/u/erzenble/run-af...71&tmax=100.90 Also does my WGDC indicate any sort of leak? thanks again.
