From what I've read on the forums so far, I kind of understand what I'm looking at but it wouldn't hurt to have input from you more experienced guys. Appreciate it

Intake, catless dp, cp, stage 1 93

N55 EWG Stage 1 93oct. What's everyone's WGDC looking like? Mine is between high 60's-high 80's. Seems high for a stage 1 flash.

Yeah mines around 70s, Its one of the reasons I uploaded my log and asked for some input.

Flashed v6.4 yesterday after a fresh oil change and changing plugs, NGK 97506 gapped at 0.028". Got to grab a log this morning on my way into work.

http://www.bootmod3.net/log?id=5d077e0dae729b541fbd391c

Some observations.

1. New boost target on Stage 2 93 octane looks to be 15.8PSI
2. I had a knock event at 3561 RPM
3. Ignition timing on cylinders 1 and 4 was not nearly as advanced at cylinders 2,3,5 & 6
4. There was a throttle closure at 5273 RPM

Regarding 2 & 3, I think this may be fuel related. I've been getting gas at a 76 gas station near me because it's convenient. I'm at half a tank now so contemplating filling up with some Sheetz 93 octane and adding some E85 to the mix (only Sheetz has e85 around here). Past experience with my car shows I can run an e25 mix and the Stage 2 e30 map pretty well without crashing the HPFP. The other part of me what's to just finish this tank and fill up with some straight Shell 93 octane and log before moving up to E mixes.

Regarding 4, I believe this was traction control kicking in. There was a slight hump in the road and at 80 mph under full throttle making it easy to lose some traction and it felt like it. I didn't see my DTC light come on but I wasn't looking at my dash.

Once I figure out my next step I'll log again and post.

One a weird side note, I went on a test drive after the spark plug change yesterday and was able to grab a couple logs. These look extremely clean BUT, when I got back home and went to tidy up the engine bay (reinstall the sound barrier foam, engine cover and strut brace), I noticed that I had forgotten to plug my O2 sensors back in…SMH! Anyway, interesting logs of this engine running open loop instead of closed loop. Timing looks stellar across the board.

The transmission flash for the zf 8hp45 is in open beta now. Just flashed it to my car.

Do you notice anything different? Do you like it?

Its a nice improvement over the stock flash. City driving was smooth. Going wot seemed improved, but I did need to do more testing.

I've noticed that comfort mode results in a more "boomy" and loud exhaust tone when compared to sport. I used to run MPPK, where switching to sport increased throttle response, so I do that whenever I enter the car now. Is there a difference between comfort and sport throttle response for BM3?

I'm interested in getting Dinan shockware so I don't have to switch to sport to get the less floaty suspension, but don't see the point if comfort and sport have different throttle response settings. My exhaust tone sounds better in sport and I can tell when I have forgotten to switch it. It's just louder.

Anyone know this?

It appears that in comfort mode it now locks up the converter much sooner which lowers your cruise RPM. This is good for fuel economy but without the converter slip it will load engine at a lower RPM. This is what is most likely causing the boomy exhaust note you speak of.

Was this after the transmission flash or the DME flash to v6.4? I've noticed burbles were much louder in v6.4 in comfort vs. sport. I'm 6MT so no tranny flash.

I'm 6MT too. I'm fairly certain it was the same as previous versions, but I'm on v6.4.

Have you ever experienced what I can best describe as burble confusion? I've had a couple instances where I'm slowing down with 0 throttle and push the clutch in and the car lurches forward as if I'm applying throttle. Usually with RPM's around 3000.

Never had this problem before 6.4. I have burbles set to max on the AGG map.

My Stage 2 FBO with Remus catback is louder in Comfort than Sport. There is definite drone at 2,500-3,000 in Comfort that doesn't exist in Sport. I don't get it, is the exhaust flap closed in Comfort causing it to resonate more? I have burbles off so it's purely exhaust sound.

Exactly what I tried to describe. It doesn't have anything to do with the flaps then, because I'm running a Dinan exhaust without flaps.

I'm auto and my burbles are at least 2 times louder in comfort then sport+ especially when I shift in manual mode in comfort

Ok well I'm baffled then.

[JaredG_F30]

I feel that v6.4 has much more aggressive burbles then v6.3

As to why burbles are more prominent in comfort vs sport, I'm not exactly sure but I speculate it may have something to do with a change in the intake system between comfort and sport modes. If you have an open CAI, I have CTS Turbo, the sound of the air being sucked into the turbo is much more prominent in sport. Something is going on there and I don't know what it is but maybe that has an impact or burbles. Again, just speculation.

Another observation from v6.4 is I've noticed the hesitation and jerkiness under light load has returned. This was fixed in v6.2. I've switched back to v6.3 as it's much more pleasant to drive and according to my logs v6.3 targets the same peak boost as v6.4. I thought revisions included in v6.4 were to boost targets but I don't see that in my log.

log from this morning on v6.3 with ngk 97506 plugs gapped at 0.028" below. I'd like to see more advanced timing. Next tank fill up I'm going to run an e25 mix on the e30 map as my HPFP crashes when running true e30 and see if I get get the timing advance into the teens.

the slight jerkiness at low load was never resolved in any version for me m235i 6mt. have you provided this feedback to ptf officially?

[ChristosD]

what wheel horse power should a m135/235 make on the v6.4 stage 2 91 map

[JaredG_F30]

No I haven't. I did create a post about it on the FB page. I wanted to reach out and see if other people were having the same experience before contacting customer service.

[Eschmacher]

For the record, I've had some low speed jerkiness, but only withing the first minute after startup - started when I installed my catted downpipe and disabled cold start. I'm pretty certain the cold start delete is the root cause. It seems like the jerkiness goes away as soon as it warms up to a certain point.

I've given up on trying to solve it. I just let the engine idle for about 30-45 seconds before I pull away, and the jerkiness is gone by the time I pull out of my street.
