I've left my 335i completely stock for about a year but since I have a ms3 I have some extra parts that I could make use of namely a standback, ewg and dashhawk. If I chose to mod the car I'd convert over to e85, raise boost, and increase timing. Do you guys have any issues with load induced fuel cuts, or boost cuts? I'd also add the ewg to the stock DP so i could relieve back pressure without throwing CEL's all the time.

good luck...

Your not from here are you... Lol

I have no idea what you are taking about

I will say MOD IT

[BreakPoint]

Megasquirt on a 335? Good luck!

hey cagey,

i know you got a beast of an ms3. but from what i read here on the forums everything is plug an play or have the cars professionally tuned.

I dont think i've seen any personal owner try to tune their own bmw as you would with the Ms3.

also, from what i read bmw is able to tell if you have tuned the computer but it only applies to some models

Never heard of 335 I on e85. I figure since nobody figure out direct injection, it is current not possible.

There are people using e85 blends with the jb4

Are you pipe-dreaming? Running an N54 on a megasquirt? It's been a while since I looked up the capabilities of an MS3, but can it even do direct injection? Can it run the wastegates (PWM vacuum solenoids), dual fully variable VANOS, EGAS DBW throttle with non-contact throttle position sensor, etc? And can MS do a better job of listening to 2 knock sensors? And then what do you do about the CAS starting the engine? The DSC integration with the ECU to run traction control?

I'm always dumbfounded when people think a $500-1000 ECU can run an engine even remotely as good as the incredibly powerful modern OEM ECUs can. Some garage electronics guys are smarter then Siemens? Bosch? Magnetti Marelli? Denso? You get the idea...

You want to tune an N54? Get a piggyback or a Cobb AP and go to town. Replacing the factory Siemens MSD80/81 is a losing proposition.

Edit: let me be clear, I'm not trying to shit on your ideas. I'm just saying that yes, a megasquirt can run an engine, but nothing even close to what the factory ECU is capable of.

i believe cageyvet made 480+ hp to the wheels during his big turbo build. MS3 are very limited to power due to fueling.

[Mike@N54Tuning.com]

Just get a tune (JB4, Proceed or COBB) and a DCI and a set of cat less downpipes and you are guaranteed to have a huge grin on your face every time you hit the gas pedal

I don't even understand the first post.. what is ms3, dashhawk, ewg.. etc.

There are a good number of people running E85 on the N54 to fantastic results. I'm actually considering running a 93/E85 blend for VBOX testing.

OP - Your MS3 CP-E standback won't work on the N54. I'd say sell your MS3 mods on your forum of choice, get an N54-specific tune (I prefer Cobb), and the appropriate bolt-on modifications. You can't convert the N54 to E85, but you can run E85 at a 2:1 pump/ethanol ratio and get away with it. Not recommended long-term though.

Methanol injection seems to be the tried and true power adder over E85 on this platform though. After extensive logging with proper parameters, I can't say i'm a full fan of methanol any longer.

of course mod it ............... why .... cuz stock sucks !!!!

Why is this??

Log timing on all six cylinders and knock volt on the cobb AP on meth when the race map comes out and you'll see.

Mostly caused by improper distribution is my guess.

Honestly, I don't even believe PWM-based meth kits like the HFS-3 would resolve this. The bottleneck is the fact even properly atomized air/methanol mix won't be evenly distributed across all six cylinders, which is more of an issue than unevenly distributed charge air.

The problem is if you inject two nozzles at the same injection point (the most common point is the elbow connecting the FMIC outlet to the charge pipe) you lose the benefit of proper atomization by cross spraying two nozzles at the same point.

I don't plan on giving up methanol anytime soon actually Just some discussion and observations. But I am in search of an alternative, and E85 seems to be the next step... at least for testing purposes.

Ms3= Mazdaspeed 3. a 4 cylinder wagon turbocharged

dashhawk is what they use to make power, as well as upgrading EWG=external wastegate.

they also use the Cobb AP to tune timing using e85, AFR, fueling, boost and much more.

I see, thanks. Im not familiar with that car at all, but good to know.

try it but i got fuel mixtures codes running cobb and 1/3 tank E85. I am never gonna put that again in the car.

I know on other platforms people have been having issues such as cracked ring lands due to having lean cylinders from meth injection. I read a good post somewhere about proper atomization, but I can't seem to find it right now. I guess nobody paid attention to this issue except for you because until something goes wrong people don't really look at the details... glad to see you taking initiative on such things we need more people to do things like this.

With all the bannings lately the pool of knowledge on this forum is suffering and the number of quality posts are dramatically declining.

Keep it up man

It's time for a direct port meth setup
Somebody fabbbb it up.
