Running stage 1+ FMIC aggres LT on my 335is. Pulls like a champ but sounds like a stuffed-up pig grunting and groaning loudly. More rattles coming from the engine than an daycare center. 9,000 miles on the car, Dinan FMIC & Oil Cooler installed. Attempted a log...think I did it right but don't see any timing corrections? Is that possible? Any input would be appreciated.

Sorry if this is too short a pull

what MAP are you running? and Fuel?

Sport? Agg.?

got some timing corrections that appear to be to aggressive for your car.

It's sport aggressive only ever used 93, drop in BMS filter.

How would one fix these? Protune? Map reduction?

Have you already done a log for sport? If not go back down to S1+ sport and do another log.

Let's be sure we are good with sport. Then we will try aggressive again. When was the last time you changed your plugs?

9k ago (not sure last time on coil packs though).

I dropped it back down to S1 Aggressive and that seemed totally back to normal (major downgrade in performance though lol) I threw in 3 separate pulls. I'm done driving for the night but I'll switch it back to S1 Sport+ (I had set it back to S1+ Aggressive figured I'd give it a night to be alone with the EcU )

Drove and pulled some wots on stage 1+FMIC SPORT ST seemed fine so I loaded Aggressive again and will get some better logs up later tonight.

[dallas_jeff]

Can someone take a look at my log, please?

I've been suspecting a boost leak these last few days because I've felt some power reduction/slower spool. Also, my charge temps have been higher than I've seen (turbos having to work harder?). I don't know if it's because the weather has been hotter lately, or if the log shows something.

for best results, please perform a log at 3rd Gear pull. 2500 RPMs to 6500 RPMs. WOT all the way.

Thats a lot going on holding AP, DS, making sure I have enough room/ ability to bring it down to 2500/ 3rd and then enough room to get back up

You're defintely on the right line of thinking with the higher ambient temps(and in result CATs) robbing power. As the temps start getting warmer performace will naturally suffer. It's just a natural side effect of summer and one that sucks . However, if you were to look into meth injection it would definitely help out with the heat soaking and provide some room to offset the loss of cool air with ignition timing. Although running the E30 map(or what i'm assuming is the E30 map based on the log) doesn't leave a lot of room for increasing ignition advance with meth but there is some gains to be had.

I don't see anything to suggest a boost leak. In fact, you had a VERY minor throttle trimming when the boost ramps up had a small overshoot so it looks like everything is good in that respect. Boost actual drops off up top but it's pretty normal for there to be a small difference in req vs act boost as the revs climb especially CATs start going north of 100F. If you want you can bump up the WGDC adder airflow values to keep the boost closer to target.

Piece of cake bro.

stay in 3rd, lower RPMs to 2500, click log on the AP, hit WOT, Shift to 4th at 6500, click AP to stop logging.

do you have an AT?

Cool thanks for the help. Yeah, I've been street tuning it, but it's based off the E30 map. I already added some WGDC adder airflow (I think from what I read on another one of your posts hehe). I just didn't know if the WGDC being in the 50's past 6K RPM seems normal? I guess I have a little room to play, but WGDC can only go to 57%, right?

It was 40-50F even here in Dallas a few weeks ago, and now it's been 75F-85F while I was finishing up my street tuning, so I guess that's what threw me off.

I don't really want to deal with meth right now ... I already go somewhat out of my way to get E85, so I don't want to also have to source meth plus the added cost of the hardware and such.

you may want to invest in this easy solution to go WOT at 2500 RPM with AT. If not you will most likely hit the kick down everytime. The best log I got was WOT at 3800 RPMs. anyway give this a shot and your logging days will be soo much easier. Its about an 5/16" spacer. This will allow you to go WOT without hitting the KickDown switch. to check, plug in COBB go to monitor and view Pedal Pos. and make sure its 100%. Also check to feel your kick down switch, it'll give you an idea of the intent of the spacer.

lol no worries I was trying for an hour ride home and I was all like F* this stupid 3rd gear then I got a wide open light and got it

I stuck a few files in and seperated them out via folders so its not confusing for anyone looking

Stage 1+ FMIC SPort (which was fine but noticeably less than Aggressive ) these were either 4th or 5th gear pulls

Stage 1+ FMIC Sport 3rd gear pull

And a final Aggressive log from when I'd be early in gear shifts and it would almost make a sloppy shift not a jerk like where your like oh S* but just a sloppy gear change. Did feel better map reset but not as perfect as Stage 1 Aggressive and FMIC+Sport.

I just took a look both my FMIC+ SPort maps have zero time corrections again not so even with the new flash of Aggressive FMIC any ideas? I do love aggressive fmic map

There's not much to gain from that log, it doesn't look like you were WOT for the duration of the pull. Grab a clean 3rd gear pull with no throttle closures, then we'll see whatsup

You might be right I might have had the damn dtc on I usually remember turning it off

Two best I could get tonight.. Sorry #7 is so long started it then waited.

Your log looks good except cyl1 and cyl5 timing gets pulled once. I would either:

1)Mix in 1-2 gallons of E85 to clean up that correction
2)Switch to Sport map
3)In ATR reduce timing a little bit

Do I need to do anything else like an e85 map? Also would this be a lifetime weekly requirement or just every few months mix a little in?

Never switch to sport map I'll break the car before I do that :rofl: (unless it had been super bad lol)

I know about the ATR Ænema gave me everything I need to get started just gotta dedicate the time which doesn't look like I'll get until late may with finals and such

Thanks again for checking always appreciate the help!

I'll check your logs in the AM, but the E85 mixture would have to remain constant (ie every time you fill), it wouldn't be a once a month type deal. The other options given above are all sound as well. If you pulled a bit of timing in ATR you could make a map that still has the broad characteristics of the aggressive mapping.

[dallas_jeff]

It looks like you let off the gas after around 5800? ... Look at accelerator position % ... It's also from my understanding that 3 degrees are pulled here and there even on a stock map, so I don't if I'd worry about it too much. When I was street tuning, I'd sometimes see timing being pulled across 3 or more cylinders at the same time, then I knew I had gone too far with the timing. However, I assumed my map was fine when I would do multiple pulls and sometimes would see -3 on one cylinder or see no correction at all, so I just ignored those.

I have been using Cobb Stage 1 Drive for months now. Recently, I installed a Wagner intercooler and then switched to Stage 1+ Drive. Holy batman, it is defeinitely more power, smoother power curve and throttle response, and I have no traction in 1st gear.

2nd gear causes me to sway left and right.
