Meow :-)

Actually, I'd be happy with the addition of the wideband O2 aspect in my system. I've noticed as temps warm up and/or ambient pressures decrease, that the tuning I was doing in winter temps was too aggressive for warm weather, and causing AFR's to dip below optimum levels. Having dynamic O2 information to adjust flow rate would add better capability to adjust the amount of extra fuel. Or if one wanted to get crazy, you could have 2 fluid containers with different water/methanol/etc concentrations/combinations and 2 pumps and automatically mix the fluid in real time based on various mapping tradeoffs ...

Yes, the sky is falling

Also, note that DPF delete decreases back-pressure, which could cause a turbine overspeed and turbo failure (or worse.) Adjustments to the wastegate logic should be made for that reason. There has been discussion of that here (and over in bimmerfest's diesel forum IIRC). One of the earlier tuners (from the UK IIRC) wouldn't sell a DP without buying his tune for that reason.

Oh wow thanks for that insight... guess I will stick with getting a JBD until warranty runs dry @70k then think about exhaust mods w/ tune

i know this is a bimmer but are downpipes (DPF delete) really that expensive for 600+? dont DP's usually run you like 150-350? [inserts DP joke]

Couldn't find a thread, but what all M3 parts can I steal for the 335d e90?

I believe i stole this list from the BPC car. wish we could steal the brakes. but if there are more M components please let me know!

E90 M3 Rear Camber Arms, E90 M3 Front Swaybar, E93 M3 Rear Swaybar, M3 Front Control Arms & Struts, M3 Rear Upper & Lower Arms, M3 Subframe Bushings

FWIW, Floyd it was Ecotune that told us of the overspeed potential of turbo if only the DP was installed without coding the ECU with Stan's specific tune. We won't go into the debate that ensued between he and PR. Suffice it to say we were fine using Renntech tune (Axel) and JR tune (me, yozh, TDI, Heather, several others in the first 10). This was before BPC became another option to us. To be clear, TDI's was a prototype before the 1st ten were sold and he did have the EGR not off but unsure if he had urea still on or not.

We were sort of lied to about EGR and SCR being turned off by Stan. I say sort of as he tried but didn't succeed. So, I take Stan's warning with a grain of salt personally. The other matter about opening up waste gate diameter is what was ultimately disproven other than Iaknown's setup needed it. I also ported but unsure if I really needed it as I didn't run with open exhaust and no porting.

The more important point here is we have to get a tune when going to DP to not do regens. I'm sure you advanced mod guys will correct me or add other things in. I appreciate being educated so set me straight please.

Tischer has a complete kit for M3 suspension that seems to be best deal (getbmwparts.com). I'll find the link and edit it back into this post if someone else doesn't give it to you first.

Thanks for the succinct summary.

Brevity has never been a strong point for me.

Subframe bushings are different. Other than that, just about any M3 part that will fit on a standard 335i can be swapped over.

For brakes, a lot of people are going to the F30 sport or M-sport brakes. Fronts are plug and play, rears require some machining and they say its best to swap out the master cylinder while you're at it. Big thread on that in the Suspension/Brakes subforum. It's a great option because F30 guys are unloading their stock brake setups for as little $500.

I'm fixing to go ahead and add w/m injection. After looking at the various controllers, I'm leaning towards the Devils Own DVC-30. Is anyone running this controller?

Also, is there a preferred pump and nozzle, etc? Or should I just go with a DO kit?

I'll probably run a single 500 cc nozzle (running washer fluid) starting at 14 PSI and maxing at 28?

Honestly, you're going to my much happier with a system like Aquamist. Injection based on injecter duty cycle or engine rpm is a much better way to inject water meth. Boost reference works, just not as well. It's literally on/off as boost comes on so fast.

Agreed. And there's people here that can set you up with a system for a good price and offer support specific to the 335d platform 😉.

1+

After further research I believe you guys are right. The Aquamist HSF4 v3.1 seems like the best prepackaged option because I can use Injector duty cycle. So, I'm going to get tuned first, and the go with the Aquamist. I just wish they had a better instruction set.

Now I just have to decide between the Jarek & BPC tunes. Decisions decisions

Yeahhh, the instructions aren't the best. I've mentioned it to Richard at Aquamist that some updates are sorely needed haha. That's where support from a specialist dealer comes in handy.

Are you sure the subframe bushes are different? How?

[RollingCoal]

Okay guys, the DDE is out, and it's either going to NC or GA tomorrow. I thought there was a fairly significant difference in the 2.5 price, but seems it's not as much as I thought. So, not to start a Tuner vs Tuner thread, but for those who are familiar with both options.....is the small price difference relative?

[RollingCoal]

It's out.

do you disconnect the battery for this?

[kydiesel35]

Yeah.. disconnect battery before removing.

Absolutely disconnect the battery first .

I took a ton of pictures and will do a new thread on DIY Pulling the DDE, because I'm not sure there is one that's extremely complete. Is it best to attach all the pics or to link from a host?

[BB_cuda]

Pulling DDE isn't really different than pulling one on a gasser. Many DIYs over on main E90 thread for this. Just trying to save you some effort. Personally, I labeled all of the connectors 1-5 using duct tape and sharpy. Be careful to seat the connectors back properly when it comes back. Enjoy the coming tune!!
