What do you mean? Are you saying that Meth or water/WW Fluid injection will help clean carbon from the intake? I suppose Methanol would work fine cleaning the windshield, though not sure it would be good for the driver behind you.

methanol is used in many over the counter windshield washer fluids, its fine

But maybe the concentration is different from that injected into the engine?

Yes and no. You can inject anything from 0 to 100% methanol though most kits dont support over a 50/50 mix and running a high percentage could be bad for your engine if it cannot support that. The correct windshield washer fluid (over the counter, find it at O'Reillys) is around 30% methanol/70% water. That fluid is actually very normal to run in a methanol injection system. As far as I know you cant find this type of fluid most places in CA, all the stores ive been to only sell 32F washer fluid.

Here's a good explanation:

http://www.dieselpowermag.com/tech/1...nol_injection/

Looks like a pretty sweet setup, easy to install and remove.

I wonder though, for those of us who aren't already a'chipp'n, whether any coding is required to install or remove water/meth injection, or is it just plug and play?

So Hooper, exactly what is the problem with greater that 50/50 concentrations?

Some sort of "support" issue?

water/methanol on diesel is a beautiful thing in part because it doesnt require tuning to take advantage of it.

melted turbines, if you already have high EGTs, would be disappointing but I think you should try it and let us know if its safe

So you're saying W/M injection could cause higher EGT?

Is it the kits that don't support the higher concentrations, or the engine turbines? Possibly both?

Ding, ding, ding. Very nice. Then I think this would appeal most to people who haven't chipped and don't plan on chipping. Then maybe we can keep up with the chipped d's, or watch as drivers who chip and meth blow their trannies and fall behind.

I don't know about blown trannies (not my cup 'o tea ) but w/m is a great idea for the 335d, chipped or not. Those 2 items are quite compatible here and neither has much bearing upon the other contrary to popular myth being expounded by certain individuals here.

The 335D trans definitely doesn't "suck" (as opposed to being "blown,") and will hold up to the mods both tune and meth just fine. Shock load coding in the DDE takes care of that.

I would for one like to try meth injection, however I really want to mod this thing when i'm out of warranty/car paid off.

I went with the JBD for ease of swapping out and had it off once for a dealer visit so far. The only question for me WRT w/m is how long I can hold out before warranty is up at 100k. I may soon feel the benefits of cleaning the intake is more valuable than another x miles of warranty, currently at ~70k.

The maintenance agreement should not be affected, right? Just warranty repair liability? Because the oil changes and brake work are the only thing I view as really having much practical value from BMW at this point.

The only thing I'm really concerned with is the carbon build up as I had 38k on the clock as of today and will be at 50k at the end of the winter at the latest as I drive a lot of miles.
this kit any good? http://www.ecstuning.com/BMW-E90-335...S766/ES517900/

I wouldn't pay $400 for that. When I searched their site for 335D specific, no w/m/ kits came up. The problem is wiring the controller. That's going to be trial-and-error without some idea what a 335D-specific pump trigger is. You have to tap into either boost, MAP or some related variable voltage. That controller may not be made to work properly or even at all on a 335D.

WRT to my quotes Hoopie, just posted, yes, and yes. When you already have a carboned up intake, W/M probably won't fix the problem. But as a (mostly) always-on preventative measure it is unsurpassed.

Context, Hoopie, context, my boy!

Allow me to clarify for those like like Hoopie having trouble comprehending complex mechanical matters: W/M cleaning does it's best in the combustion chambers themselves and things downstream in the exhaust. Improved combustion efficiency, lower EGT and steam effect is what does the work there. Not going to do much on the intake side, regardless of injector placement, but will definitely prevent buildup.

I see. The context of cleaning the intake, I confused that with the context of cleaning the intake. Cant believe I didnt catch that.

How will you prevent buildup without affecting existing buildup? Honestly curious what the theory is.

Honesty doesn't seem like one of your more remarkable traits, Hoopie.

If you were paying attention instead of just trying to discredit me you'd be way ahead of the power curve here. Why don't you just keep on thinking about it - maybe it will come to you some day.
