CoolingMist has this sensor/flow detector:

yep that is a pressure switch like I was talking about only with the fittings built in...a good simple solution.

As it turns out, devilsown has a calculator they released for this.

So are most people using the progressive (like devil's own controller), or single-set point setups like I'm considering? And when is your injection onset?

Without having done too much research, I'm looking to start injection at 10psi. I boost peak at about 17psi. But if I'm passing 10psi I'm driving agressively, so chances are I'm already on my way to 17 : )

[C30T5*36]

I run progressively starting at 4psi and peaking at 12psi and 25% to 50% IDC. My pump is set at 180psi on a 225ml/min nozzle. My setup is snow performance stage 3. it is weighted 75/25 boost/IDC.

I run the Devilsown progressive. It only uses boost pressure (no IDC) to control injection. They recommend setting the spray to start at 25% of targeted boost and the full spray at 75% of targeted boost. I run 20psi boost and have mine set to start spraying at 5psi and all in at 15psi. Use the nozzle calculator as a guide, you may need to adjust the nozzle size. I'm using the DO5 nozzle.

I've got the same system sitting around, need to get a bigger turbo. Once thats done plan to tune without the WMI then instsll and advance timing accordinly, this way I can switch the tune if I run out have a failure of some sort. Are you pleased with the system?

Yes. It is easy to install and makes the car run smoothly. The pump and components seem to be of very high quality. Also, the controller is very easy to tune.

I agree. The design of the controller really makes it hard to have a clean install. While I like the Devilsown system, the reviews were good and the price was right, if I did it over again I'd probably go a different route. I'm afraid to run a very aggressive tune, because the system has NO failsafes at all. If my tune was right on the edge and the system failed for some reason, I'd be in trouble. So I keep things conservative just in case. I'm wondering if I could possibly install some type of flow sensor in the line to the nozzle that would alert me in case of a failure?

AEM offers a flow monitor. I bought one, but haven't installed yet. You should look into it. It's a little on the high side, but if you are tuning around the flow, then you need it if it ever stops.

I ran a .7 for a while, but dropped back down to a .5 and raised the point at which the pressure comes on. Been running WMI for 4 years now or longer. Woo.

Aquamist race pump, separate reservoir and I have tried the .4 .5 .6 .7 jets.

I felt like the .7 was maybe drowning the engine a little bit even up top.

I have this flow meter. Back when I bought it, John Howerton (I think it was John) asked if I could do a flow test on it, as they had heard the type of sensor used by AEM was prone to being "off".

I never did get it to work in general as I never got around to converting 6mm to 1/4" for the connections. The sensor has an in/out of 1/4" and the aquamist is 6mm. So I needed to convert from 6mm to 1/4 and then back to 6mm on the other side of the sensor.

The gauge overall is nice, although it seems to be flakey. You can change the color of the back ground which is nice I guess.

You can get fittings from your local parker store. the threads should be 1/4 npt, the same as the filter. I just picked up a Coolingmist CMGS v1.07, with the flow sensor, so I will be using it, unless the owner Perrin PWI-1 I have been looking for turns up. It's only a IDC signal, but I am sure that I can find a 0-5v to pwm convertor for it.

[550]

From everything I read, the sensor push fit connectors are epoxied on there in some form or fashion and that taking those off will damage the threads. Otherwise, I had originally planned on doing that :-/

THey sell the sensor either way now. Might want to shoot AEM an email about it.
