I just updated to Stage 1 Aggressive v401 on my 08 335i and got the following codes:
P29CD
P29CF
P29CC
P30FF

I run only 93 octane no ethanol. Only mod is BMS intake. I was running v301 stage 1 aggressive previously with no problems no misfires at all. My plugs are less than 10k old.

Any ideas?

The P29 codes are misfires, since you are having multiple misfires its more than likely the spark plugs. This is really common on all the tunes.

The P30 code is what's normally referred to as a "boost leak" code. However, it is actually triggered whenever actual load is far below requested load and that easily can be attributed to the misfires.

My advice is change the plugs and go from there.

I was taking into consideration that most I've seen run about 315-330 at the wheels on stage 1 which is about 375-385 at the crank.

On what dyno? And what's the stock baseline?? I could hook my car up to a dyno & get 1,200 WHP/1,500 WTQ & it's not worth anything w/o getting a stock baseline 1st

Tune only, I dyno'd at around 320hp. What's wrong with his claim?

The stuff is bold is my issue, I have no issues with 320 WHP, 390 crank HP sounds so damn high for Stage 1 Aggressive

[Mr. Nice]

I hit 334whp on stage 1, 276 baseline which would be 392 and 324 crank respectively, assuming 15% drivetrain loss, seems reasonable

I think he was estimating based on drivetrain loss. He's probably within 10hp realistically based on 15% drivetrain loss. Not to mention, it has been proven that the N54 HP/TQ numbers are underrated from BMW.

[benzy89]

Well if it adds up, good deal. Just not used to hearing Stage 1 numbers that high or even contemplating crank #s in general

Probably because nobody quotes crank numbers. It does seem high but when you crunch ESTIMATED drivetrain loss numbers, he isn't too far off.

That's a nice increase. Mine put down 279 stock and 329 with Stage 1 on a Mustang Dyno.

I baselined at 280whp/300wtq and on stage 1 aggressive I made 330whp/380wtq. Some ATR FBO+meth map numbers coming next week.

I'm getting these numbers from the Cobb website indicating a 30% hp and 38% tq increase. The reason I ask is that I'm not a heavy tuner and I have no plans on ever taking my car to the dyno. Thanks in advance.

As I talk to more and more locals who've dyno'd, I'm beginning to think those numbers are inflated.

My dyno was on a dynojet, NOT a Mustang which typically reads lower. Granted it was hot out, but I put down 344WHP/387. First that's SAE, which is really how you should rate it. A lot of people seem to be quoting STD, which is not as commonly used. Mine was 351/395 on STD. However, I have Stage 2+ with VRSF downpipes and ETS 5" FMIC. Yes, no full turbo-back exhaust, but I have a really hard time believing that it'd actually gain more than MAYBE 12WHP...and probably closer to 8 or 9WHP. I understand different downpipes and different FMIC's may product more horsepower, but I doubt it's 15WHP more just by a particular combination.

So yes it was hot, but we had a good fan running and I doubt it would have increased the horsepower by more than maybe 10WHP. So with an exhaust and maybe cooler air, perhaps 22WHP more? That's 373 if I was rating STD. And that's still not on a Mustang which would rate lower.

I'm confused how Stage 2+FMIC without E85 or meth are getting the numbers people are posting. The only locals I know who are posting big gains over mine have both meth and E85 and that can make a huge difference(low 400's easy, even mid 400's with a more aggressive tune).

Every dyno is different which is why a baseline is so important. People put way too much importance on dyno number (myself included sometimes).

+1
Different dynos read different and without a baseline the numbers themselves are pointless. Dynos should be used as a tuning aid and to verify power gains. It seems a lot of people don't understand that.

[benzy89]

It's all about the Deltas

[VNeBLOB42]

^^^ not to be off topic but my baseline was 230whp on a dyno dynamics, aka heartbreaker. I guess my point is there are a lot of variables. I know I am a noob, but all I am concerned with is the delta. I'm happy with what I got and as long as my logs are good I am good.

Edit: S1+ aggressive delta in a couple weeks.

[VNeBLOB42]

Noob question.. my baseline was in Feb. Should the baseline be within the same day of the upgrade? My delta test will be the same dyno same shop.

As long as the dyno is conducted in similar conditions its OK. If it is done in different conditions then that's what the SAE correction comes in. Using the correction factor roughly keeps things equal. Assuming your Feb dyno was SAE corrected and your new dyno are SAE corrected then it should be pretty fair.

10-4 thanks.

[toms335i]

hey guys so my AP came in today and Im curious which map to download. Currently the only engine mod on my car are Riss Racing dp's. Love them so far, need to know which map is best with just dp's.

Thanks in advance,

Tom
