WhiteEvo05, I've been running the High Speed PWM Valve with my Aquamist 2D water injection system https://www.evolutionm.net/forums/sh...light=Aquamist for over 3 years now and it has been working perfectly. I've been using it with my Xede with S.M.A.R.T. I have the water mixture spray activated at 13 PSI and it's triggered by a pressure switch not by the Xede. The Aquamist just works great in harmony with the Xede.

 

in the 2d/dds3 setup i had in my VIII, injection comes on @4psig.

Very interesting to watch the light on the FiA2 as it mirrors the IDC, during low inj duty, you can see the light blink in distinct pulses, when you reach high IDC, the light would pulse so quick, it looks like its staying on.

 

Using two injectors spaced 6" apart along the length of the inlet tract sounds like a good idea to me.

 

Is this an Evo specific kit or is it universal? What about ease of installation and tuning? Does it include Evo specific instructions? Can the average guy install one of these, or is it best to have it installed and tuned by a professional?

 

With the new conditional logic that is enabled in the newest versions of Xmap, and the lean run protection mostly debugged, the Xede will offer a good primary layer of failsafe protection with the DDS3/flow sensor as a very strong secondary hooked to a boost limiter such as you have installed.

I am still keen on trying to get the SMART Xede auxillary injector control enabled because with the conditional logic and nesting of maps, you can have a variable threshold for start of injection based on load, rpm, boost, etc...

The fact that you have good luck with your system for a period of years is reassuring.

How far from the throttle body do you have your nozzle installed?

 

Richard L: Here is a link to Canton-Mecca's canister filters...they are somewhat large-ish, but they do have a filtration of 1 micron and are a full flow filter. I know the pressure drop on this unit is low enough to run it on the suction side of many fuel pumps...I had good luck with this configuration on my E36 M3. The filter media will withstand petrol, alcohol and nitromethane...I would think it would withstand straight methanol too...need to check on that.

They have in-line filters with 8micron filtration. However, I don't know if the pressure drop on these is low enough to use on the suction side of a pump. Maybe with the use of a small primer pump, such as EvoTio has, this would not be an issue.

This and good housekeeping is the best way I can think of to prevent clogged jet problems.

My nozzle is located in the factory aluminum UICP right before the black flexible bend piece to the throttle body. I have it mounted under the pipe so it is not easily visible. I can still access it easily for nozzle changes. You have to size the nozzle properly to your application in order for the High Speed Valve to work it's best. In my current set up, a .7mm nozzle has worked out the best so far.

 

I know someone uses the Xede to form a closed-loop failsafe and it appeared to work well.

The Xede reads the flow sensor voltage (0-5V) and use it to trim map. Unfortunately not many people realise or undwerstood how well this configuration works so the thread died pretty quickly.

Here it is again:

Thanks very much for the link.

These filters looked great. We have in the past people using fuel filter for water but after a while, the fabriic/paper element deteriorated and produced some fury debris and clogged the nozzle.

I will investigate further with them and find out how well they work with 50:50 water/methanol before recmmending them to our users.

 

For straight water, you might check on a company called Racor (division of Parker). They make fuel/water separators for diesel applications...perhaps they have a low micron filter that is good for use with straight water. I believe they have applications for Marine water systems, too...might be worth a look in to.

I know that it is difficult to find filters that are compatible with water. Customers in my region are starting to look in to using BioDiesel due to lower operating costs...the water content in the fuel is murder on filters. It cuts their life in half.

 

So for port injection (to get this thread back on track-ish) with this system, would you recommend four injectors (one for each intake runner, positioned directly opposite the opening to the runner in the manifold) and a nozzle in the upper IC tube? How would you size the nozzles properly (new to this, remember)?

Or would it be better to somehow mirror the duty cycle of each injector with it's respective nozzle...would that be overkill?

 

This would be very cool if the SMART enabled Xede had any analog inputs left open. jjoo8 was not running SMART if he was inputting the 0-5v signal form the flow meter.

Lean run protection works by monitoring the wideband o2 sensor and if the conditon is lean for longer than 500ms then it does a full boost cut (wastegate actuator acting alone, ~11psi). If the lean condition persists for ~1 second more then it does a hard fuel cut. The second value could be shortened, I suppose without too many problems created.

I run boost compensation based on temperature through a module that Freedom figured out how to do. He actually had to take the 0-5v temp signal and convert it to a PWM signal as that was the only input left...well, there might be another PWM input left, I will have to check. Could use the same module to convert the flow sensor signal. Of course it looks like the same thing could be done (with the exception of pulling fuel...that would be through lean run protect) with the DDS3 as far as boost cust based on flow meter signal.

If that had been posted in the Vishnu forum, there might've been more discussion.

Might have to PM jj008 about his results.

 

I am sure if can be made into a evo specific system if someone is kind enough to make a full wriht up and measure the cable and hose length. I suppose a part sponsored deal will be on offer in exchange of a full write up.

Tuning should be pretty straight forward due to the fuel idc tracking, therewil nopt ne any unexpected gaps.

 

Thanks again for the link, these are valuable information. The filters offered are of very substantial construction. I think it will be up to the user to buy from them and replace our filter if they think necessary.

At present, we don supply a disc shape inline filter, available in 100 micron and 30 micron mesh.

 

You are probably correct, there are no spare input channels to read the flow sensor when smart is added.

It i s possible to convert the flow signal to a PWM signal but it just complicate things. We do have a small building block based on a 8-pin PIC, it converts a 0-5V to 0-100% PWM.

We are beta testing a progressive MAP clamp, the flow sensor trims the mAP sensor voltage. You can view it here.

The wideband failsafe will only work with near 100% methanol application. I doubt it will be reliable for 50:50 mix.
