First time logging so apologies if I did not capture the correct attributes. Running MHD Stage 1+ on 91 octane on my 2007 335i (mods in signature below):

http://www.datazap.me/u/dustinsterk/...a=2-3-14-23-27

Car feels very strong and pulls hard, but wanted to understand what things I should be looking out for. Something I noticed was that the throttle position was only at 80 while the accelerator was pegged at 99%.

Also some pointed out lots of timing corrections in third.
Stage 1+ does recommend a upgraded FMIC and I see the IAT going up and the timing adjustments correlating. Do you think that could be the cause or do I have something else going on here?

Any other red flags or concerns?

Thanks in advance.

thats normal.
Started pulling timing pretty early. I think thats just a little too much boost for the octane. Dump some e85 in and see what happens. And you really need to do a 3rd-4th gear pull to ensure you got a good load. Looks a little rich. Most everything else looks ok. When were plugs last done? Set the Water pump option to sport to help reduce the oil and coolant temps. That will get you a little more headroom on retards.

Kind of hard to tell if it's IAT or octane. Either add some octane AKA race gas or E85 or get an FMIC upgrade

Eitherway, you should consider the FMIC upgrade regardless.

I agree topg but it quickly goes to more than one cyl when inlet temps have only gone up 2 degrees. I would also suggest a pull on just stage1 with pretty much all else the same. And maybe even a different brand of 91. That will let you more know whats happening.

No doubt on that recommendation. Basically just need to change something and note differences if any.

[dustinsterk]

Great thanks to you all for the suggestions. FMIC and CP are ordered. Before I install any of the upgrades I will try a 3rd to 4th pull with different gas (this 91 octane is from WAWA, so probably not the best in terms of quality), then another on the downgraded stage 1 map. The plugs were just done (according to the previous owner) probably less than 10k ago. I appreciate the help.

Make sure you turn off traction control. By holding the button until the light pops up on dash. This can also cause some timing cuts. Also have you touched your LPFP or the sensor. From your HPFP it looks fine but you LPFP pressure does not appear to be reading.

[dustinsterk]

Hmmm interesting...I will give that a try and also look into why my LPFP is not outputting data. I just purchased this car so it is possible something is unplugged.....thanks for the heads up.

[335e92tx]

Yep, good eye. It did log a torque limit event at the top of second gear it looks like.

[dustinsterk]

Can you tell me what a torque limit event means? Could this be due to sensor?

No,, prob not the lp sensor. It means for some reason it detected a traction issue. Since its right before you shift i can't conclude its significant, The ones that just flat cut power are 2054. Prob the max value. The log you have shows two event at a value of 1. Prob not really breaking traction..

[dustinsterk]

Great thank you!

[dustinsterk]

So I finally got around to replacing the LP fuel sensor/line and installed new plugs & coils, BOV/CP and upgraded FMIC. Here is a new log running 93 octane....I still notice some corrections on cylinder 4 and 5...is that normal? This time DTC was off (held for 3 seconds)

https://datazap.me/u/dustinsterk/log...10-12-13-21-22

I sometimes get a cylinder 2 misfire on a cold start (seems to happen after a refuel), but then after warming up it runs 100% smooth. I am wondering if my injectors need to be replaced.

Everything else look ok?

[335e92tx]

Pretty good. I would not really worry about the timing pulls on 4 and 5. You could try moving those plugs/coil to either 1-3 or 6 and see if the problems stay on that hole. IF so it just might be getting a little more oil or run a little hotter than the others (common for #5 I Think).

The one for 5 is right after a shift and it quickly drops down from a 3 degree retard. I see you dont have some boost options getting logged - that would help to see if you are about to trip the boost target (and you actually did exceed a load target - prob boost bc it was at 14 - at about 152secs in and in 2nd gear at 5600 rpm. )

I would turn off timing for cyl 6 (you only really need one active in general for advance bc the DME does the same advance for all I think) and also the WGDC#2 - I Think the DME also controls both WGs the same vs trying to manage them (and boost) independantly. And turn on Boost Mean and Boost target.

Most everything else looks ok but until you get a few more boost metrics its hard to say for sure.

So, this cyl2 misfire, its actually logged?? Thats kind of strange.. No others. Usually cold start misfires can be injectors or HP pump. But its rare just one injector goes... What are total miles again?

[dustinsterk]

Thanks for all of the feedback. I will change up the logging parameters as you suggested and repost another log.

The cylinder 2 misfire is not logged, it has only happened twice after a cold start both times since I installed the new parts (seems to correlate to after i fill up). I get the service engine soon light on the dash. Total mileage is 156k.

Id start saving your $$ for a set of injs.

[dustinsterk]

Yep....looking at buying them very soon from FCP.

[dustinsterk]

So I changed the logging parameters and have posted a new log....more timing corrections are additional cylinders and I see at times boost surpasses the limit in the upper RPM ranges.

Yeah, your getting a little retard in 3rd. But really thats a decent amount of boost for just an S1 map. You could maybe dump in a little ethanol (eh NJ, yall got grain you dont use for drinking Alcohol in NJ? ;-) ) and see if it suppresses the retard. Not a lot can be done with the off the shelf map. If you go to S1+ it will tend to try to back off timing a little more. Your not logging cyl6 timing corrections- you still have the advance option set for that. But it is interesting they are controlled independently. What Cyl 1 has is not what cyl 6 does.. they do seem to be with about 2.5 degrees. So what other mods you got again? I would think it runs good with what I see.. and what else is planned?

ID say right at the top of third there is not a lot left on the table. You are just about at peak boost and load. Next step is either more mods and/or custom tune.

[dustinsterk]

I assume the "S1" map is the same as MHD Stage 1+FMIC (which is what I flashed). Lol, we do have some gas stations up here that sell race fuel, but yeah...its NJ. haha.

I turned off cyl 6 timing so I could log the other items (boost mean and boost limit). Should I turn that back on?

Mods are reallly just bolt on: CP, Tial BOV, 5" stepped FMIC, dual exhaust tips (not full catback) and of course the MHD flash S1+FMIC. I really am pretty happy with the power its making.....for now. I worry a little going any higher of a flash with too much boost with 156k miles on the engine without rebuilding it. Maybe I am being over cautious.

[335e92tx]

considering the miles and what you got Id (personally ) just live with it a while until you got injectors.

So no DPs planned? I would say after you get the injectors done jump another 350$ for a custom tune. It will be worth it. You can get just about the same HP as with DPs. It would probably be able to live a while like that IMO...

[dustinsterk]

Was not sure, was thinking the same ....custom tune from Ken @wedgeperformance or DP's. You think injector and tune over DP's? Thanks again for your input and help!
