Finished the wiring part finally and tomorrow I will install the underpanels back on and drop the car off the rhino ramps. Hopefully I can test it out but like always it has to rain! Keep you guys posted on my progress.
The only bad thing I can say so far before even testing the Aquamist unit is the damn tiny wires that it uses..Its something 26 guage wires and used Last edited by cn555ic; 12-19-2011 at 10:37 PM.. |

looking forward to your results, I have been looking at that unit for a while now. Mind sharing how you got such a good deal?

Tested the older unit out and it doesnt seem to work It shows flow of 78-79 but the Procede unit keeps throwing a overflow code and goes into a valet mode which makes the meth system not work...I guess I need the newer version one! SUcks bigtime

http://en.wikipedia.org/wiki/Voltage_divider In order to choose the resistors, you first need to measure the current between the sensor and the Procede using a multimeter. Then using the Ohm law ( I = U / R ==> R = U / I = 5v / measured current) you can find out the total resistance needed (R1 + R2) in order for the current to remain somewhat the same. And then using the voltage divider equation (3.3v = (R2 / (R1 + R2)) * 5v) you can find out R1 and R2. And that's it. You can also use a single potentiometer instead of 2 fixed resistors, so you can better adjust the sensor to the Procede. Last edited by tscdennab; 12-20-2011 at 03:24 PM.. |

I checked out Enrita thread and he had to calibrate the green wire, on mine there is no calibration at all and it's just one mapping of voltage compared to the newer one with 3 voltage mappings. Sucks that I have to buy the newer one which I just ordered. If the new one doesn't work, I Am going to flip the fu.Ck out

At this point Jeff to be honest. I do like the notification with the hazards lighting up to indicate max meth flow, but after I get the new one and it's still having issues, I might as well goto Cobb or JB4 at this point. Procede support is getting to be like a distance island that you see while stranded on a life boat waiting to be rescued |

I will put it out there. But Shiv can you help re-scale the aquamist flow sensor for us PPS meth kit users. Is there some user tunable adjustment that can be made on the Procede software? Please help if you can

even with the newer version i was getting overflow on procede since with 2 nozzles i was seeing around 72 max flow. with 1 nozzle 50. 1 nozzle worked fine but with 2 overflow was triggered. so seems after 70 you cannot use the sensor with procede till Shiv allows to change the reading in the procede.

I will be using a M10 and M7. If you are using two M10 then I might have a chance at this working hopefully lower than 70 reading would be perfect. I only use M7 for nitrous spray.

After ordering the new unit and speaking with Shiv about what to do with the wiring, it finally works! He suggested to use a voltage divider to the flow wire of the Procede to reduce the voltage...Essentially it drops the voltage in half by using a 2.2k resistor and 1k resistor. My flow is showing a steady 21 right now using a M10 nozzle. I have yet to use the other meth power nozzle that triggers with Nitrous, but Shiv said it should work and show flow somewhere around
30-35 and still not induce a overflow fault in the Procede...I was beating the crap out of the car and inducing the car to go off and on meth, and each time the sensor kept reading perfectly on que! Unlike the Snow unit when the car hit around 250 oil temps it would not function at all till car cooled down, but then again sometimes the engine wasnt that hot and it still crapped out, so I am not sure why its not working all the time...Again this could be where my location was before, I am not sure...Either way I was checking out the engine bay to see if I can relocate the SP unit and there is hardly anywhere I could think of to install this big flow sensor..I found one location all the way at the back of the engine bay near the firewall, but a custom bracket would have to be fabricated. Since I alreaAdy bought the Aquamist unit, I was determined to get it working...Now its fully functional and the size of it made it so easy to install almost anywhere in the engine bay. Compression fittings FTW! Last edited by cn555ic; 12-23-2011 at 10:14 PM.. |

awesome, glad you got it working. You will have to do a full description of how you wired it all up with the voltage drop so others can be sparred the headache.
