Hi Saif

Could you please tell me how these compare? the first log you looked at was Shell V-power fuel. This is that log again -

https://datazap.me/u/335icoe/335i-st...og=0&data=3-22

Second link is Momentum 99

I've been using this fuel for around 8 weeks now, was tested by a reputable UK tuner that it was better.Thanks

Second log is much better, very few minor corrections, 👍

Having an issue with high intake temps!? Even after the upgraded intercooler. Is there a reason for this? Also my car is still running pig rich

My car drives fine for the first 20 minutes then my turbos start to lag massively

https://datazap.me/u/boosty/high-int...og=0&data=3-22

This is just a quick log. I'll do a proper log when I get the chance.

You can see my high intake temps and high wgdc?

Any help would be appreciated

Yeah IAT is up there. What was the ambient?
btw you can log in °C by going to Datalogging options>Configure options

mishimoto cooler have never really been very good imo.

If you have an updated log post it up.

Hi mate! I managed to pull a log. This is the best I can do without losing my licence.

https://datazap.me/u/boosty/logs-e90...og=0&data=3-22

Intake temps reached 130 at one stage!

My main issue is running mega rich, late spool and change in exhaust note.

I have changed almost everything in this car and still running rough.

Recently I've noticed an intermittent weird idle. I finally got it with my MHD gauges and I showed a spike to 2700 psi for the HPFP. It's only a second or two, but you can def tell something is up because it seems to stumble. So I did a 3rd gear log to see if the HPFP was an issue and I'm not seeing any issue with it in the log. Would someone else mind taking a look? Also is the timing adjustments for cylinders 1,4 and 5 an issue? Any tips/advice is greatly appreciated. I'm trying to make sure my car is running great before I install my single.

Currently I'm only MHD Stage 1 w/DCI.

Log looks clean, can't see anything wrong with LPFP, HPFP. Timing corrections are minor, nothing to worry about. Don't forget to log timing cylinder 1 in future.

thanks for the heads up. I must have turned it off inadvertently. Thanks for the input, I really appreciate it!

Hi again Saif, thanks for the previous reply!

I've installed my old aluminum charge pipe / bov that I took off a few months ago, would you be able to tell how these compare, I feel like it's not holding boost as well as the standard charge pipe did ? Any help appreciated

First log is standard chargepipe

Second 2 are just after installing uprated pipe and bov.

Looks about the same to me, slight variations in boost on logs are normal. Not sure why you took off your aluminium charge pipe but it's quite common for stock plastic ones to crack, especially when tuned.

Stage 1+ map will taper off to ~ 14-14.5psi up top.

Hello everyone. 2012 335 n55 on mhd stage 2, downpipe chargepipe and that’s really it. I have been having some weird issues strictly at idle and to be honest really only happens in park. Almost always when the car is warm but my car started up weird today so I figured I’d grab a log of what’s happening. Basically the car has been shuddering a bit and then shortly after it figures itself out again and is smooth as butter. I can feel the motor shaking and can hear a tapping noise almost when it does happen.

Here’s what my log is, I cannot really comprehend what exactly is happening here hopefully someone can bring some insight. Notice “timing crk” on cylinder 6 is higher than the other 5 cylinders and at the same time rail pressure is dropping significantly.

Thank you in advance.

LPFP looks fine,

Run a stage 2 map since you have downpipes.

I will this spring, I will update you then. Thanksss

Hi guys, I've been trying to understand why my boost is dropping around 5300rpm or so. The log makes it appear I'm targeting a lower boost but that is not the case. Well, I'm trying to target a lower boost at that rpm. This is my attempt at self tuning.

I can run an OTS map and the car will not behave like this. So I believe it is the tune but just don't know where to look. Any help would be appreciated. The car is a n54 with 17t's and all the other things. I know the tune is not there yet but just trying to understand why the strange boost drop. Thank you in advance.

Enabling the Custom 3D Boost Ceiling Table helps alot. I had nothing but trouble with the oem boost target tables.

Table is "Boost Ceiling (Relative) (Gear x RPM) (Map 1) Target is set in psi, and can be done for multiable maps if you going that way for map switching.

Example of my setup below.

Thank you for the feedback. I have often looked at those tables but didn't know if it would cause other issues. I'm guessing this will override the load table.

All good. Up the load out of the way if required.

Hi guys, i recently traded my 350cdi for a 335i and was a bit surprised how it was slower than my merc from 100-200kmh, first pull with dragy showed 16.7 100-200, after some research i couldnt find the exact number of how fast an zf6 335i stock is supposed to be, some places say 13.7sec others 15ish seconds, but i do not believe that a nearly 310hp petrol car is 1sec slower than 295bhp (dyno) stg1 350cdi, so i opted for mhd stg1 and xhp stg3 which dropped my 100-200kmh from 16.8sec to 13.5. Car is completely stock other than previous owner took out the middle cats, i am not very good at reading logs so if someone could share some insight at how it looks it would be great, also just to note i am from eu and this run was done on 95ron fuel while my best dragy times were on 100ron and ambient temp was around 10celsius i notice my iat went to 50c, is that super high?

https://datazap.me/u/nidjo95/log-167...og=0&data=3-21

Quick edit, the chart above is mhd rattle fix on max less rattle, and this one https://datazap.me/u/nidjo95/log-167...&mark=91-73-93 is on less lag, car feels more powerful and i dont know why but IAT temperatures with less rattle go up to 50c, while on less lag are way lower

50C is getting high, one pull and it went from 22C to 50C, FMIC upgrade is highly recommended.

Stock 100-200k times for a 335i should be around 14.5 secs, the fuel your using and your IAT's are likely causing the numerous timing corrections, if you have access to 93oct/98ron or better fuel use that

If the car is decatted, you need to run Stage 2 map.

Guys. I know this is not a pull to 6k rpm but it's best I can do without losing my licence

My torque value is abysmal. My intake temps are through the roof despite having an upgraded intercooler and my WGDC is through the roof.

Can someone please explain what Is going on with my car

You will have more lag on 17t at lower end of rpm, that's normal. You went WOT from about 2.5k and it reached boost by about 3.2k. WGDC is meant to go to around 100% until it reaches boost target then settles down. Yours goes down to about 50% after reaching target so I don't think it's through the roof lol.

I'm not sure if the torque value means much, is the car pulling hard, Transmission remapped?

Which FMIC have you got and have you checked all the connection points over?

Assuming your on a custom map, send the log back to your tuner.

Yeah im looking to get a fmic asap, just not sure which to get a friend recommended wagner but im not sure if i wanna drop 1k euros on an intercooler.

Car doesnt have middle cats, but the downpipe is still stock with cats so im not sure if i should run stage 2 as i thought u need catless downpipes for stg2

Yeah ive got 95 or 100ron on the local gas station, i usually fill with 95 as i thought there was no need for 100, but i will fill a few tanks of 100 and do a few dragy funs + logs.

Thanks for your answer
