lookforjoe Posted September 16, 2011 Report Share Posted September 16, 2011 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?

Che'_Moderator Posted September 16, 2011 Report Share Posted September 16, 2011 What tune are you using? You want to use as little water as possiable. Tune plays a big role in that Link to comment Share on other sites More sharing options...
Volvo5.0 Posted September 16, 2011 Report Share Posted September 16, 2011 CoolingMist has this sensor/flow detector: Thanks Hussein! Seems like what I need. What tune are you using? You want to use as little water as possiable. Tune plays a big role in that I've been playing with turbo-tuner. Right now I'm running 50/50 water/meth. Are you saying to run a higher percentage of meth? Why as little water as possible? Link to comment Share on other sites More sharing options...

If you are not getting any at your current timing/boost/load back off until you get a hair then add back say 10% for for safety. Link to comment Share on other sites More sharing options...

I could try backing off the meth/water a little, but it seems to be doing its job.... Post 172 shows the logs with and without WMI Link to comment Share on other sites More sharing options...

the commissar! Posted September 16, 2011 Report Share Posted September 16, 2011 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. Link to comment Share on other sites More sharing options...
rbodor3 Posted September 19, 2011 Author Report Share Posted September 19, 2011 As it turns out, devilsown has a calculator they released for this. http://www.alcohol-injection.com/forum/nozzle-size-calculator/alcohol-nozzle-size-calculator-351.html 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 : ) Link to comment Share on other sites More sharing options...
C30T5*36 Posted September 19, 2011 Report Share Posted September 19, 2011 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. Link to comment Share on other sites More sharing options...
Volvo5.0 Posted September 19, 2011 Report Share Posted September 19, 2011 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. Link to comment Share on other sites More sharing options...
T5Hammy Posted September 20, 2011 Report Share Posted September 20, 2011 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'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?

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.

JWL Posted November 22, 2011 Report Share Posted November 22, 2011 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.

550 Posted November 22, 2011 Report Share Posted November 22, 2011 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. 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 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. Link to comment Share on other sites More sharing options...
