How about a buld off
All of you sound like you know what your doing and have stalled in your brilliant ideas over witch hardware to build on. Simple answer. Both/ all and let us have some fun with our hobby ,that saves some cash,advanced ourselves and our community together
Lets push back the boundarys of what current technology can do, and make it what it will do.

Ive Been talking with the family computer guru about him helping me work with the Raspberry-pi. He has built a mesh network with this device, this is why I chose to have my pi and eat it to. To be able to prove my mpg/CDa improvements I need a data loger as sophisticated as a new car. Installed in a car that thinks a computer is a brand of tire. You can see I've been thinking about this for a few weeks and found this posting. About people trying to open sorce build a platform that can expand to meet the needs of the Community be it 1or 2 data streems,like your simple gas non- turbocharged dual fan progressive fan controller or like me and could exceed 100 points of data to control the fans and different pumps,shutters propane water heaters, aero Modds ,multi level hybrid. Ground effects Russian dall boat tail all but the water heater are ideal ideas on this website that have stalled have stalled waiting on this project . This first step and giving our creations a BRAIN



1 thing I know for certain , is WITH THIS COMMUNITY I can see 50mpg From a 5600lbs full size truck only 25avg on 5 trips 200mi round trip over the Rockies . for now

How about both of you throw down your best controller. Or at least able to run my 4 parameters on a progressive rate
(-)5000cfm@45mph through 15000cfm sitting still.

Now what I need to control my 4 parameters of cooling with 3of the largest cfm fans available (3k-5k cfm ea.).
I am not biased Im just wasting 25hp of fan to keep the thermostat closed a @165°f, the stock cluch fan kicks on @ 180f Off @ 175f the same as the opening of the thermostat
Previous Owner advised me not To go back to the stock 98°C because"it will kill your mpg"
By making the 25hp Fan run all the time.

Option1
Update to 3rd generation electronic fan cluch.
Could a person use a variable speed fan controller to achieve the same variable % of lockup? Eg the hotter the radiator the higher the voltage the fan sees/the higher %of lockup? Or is the signal a 0-5vdc standerd automotive computer language ? If so this can be worked around.
Option 2
Stock replacement? And adjust the bi metal spring to come on at say190f Instead of (my original equipment )180f on 175off coolant temps.
Option 3
full custom progressive 9,000-15000 cfm electric fan, would be comparable stock 10,000cfm macanicel fan?


1 coolant

step1 180f 1000cfm step 2 3000cfm 185f step 3 190f 2nd fan @1000Cfm 1st @full step4 195f 2 fans @full 3000cfm ea step 5 200f fan #3 @ full 3000cfm for a total of 9000cfm

2 iat(Intake Air Temperature )

Step 1 130f 1 fan full step2 200f 2 fans step 250f All 3 @full
As per cummins any iat Above 90f will reduce power at a rate of 1%per 10°f above 90f https://drive.google.com/file/d/0B0l...p=docslist_api

3 ac/defrost compressor

Add a head pressure switch from a class8 for 1 fan only.
The stock Dodge AC safty SWITCH WILL hit MAX turn the FAN ON for a moment 1-5 sec, simultaneously turning off the compressor,
Pressure drops turning the FAN OFF (as a safe level has been achieved )turning the compressor back ON for a few seconds 1-5

3b Ac / defrost compressor
Wire the compressor to a fan . Compressor ON fan full ON compressor OFF fan full OFF . No good with options 1,4and5 (opinions wanted )

4 trans temp
150f a separate fan on the air to atf cooler with a reverseing contactor relay to reverse the fan pulling hot air from under the hood @80f to keep it warm. @-10 and lower so that as per Dodge tsb#07-01-89 TSB 07-01-89 I dont have to drop to 3rd to keep the atf from freezing and burning up my trany killing FE yes this is a problem Butte, MT is listed as the 18th coldest city in the continental United States

Now for my contribution :
Clean X vdc any from supply down to 4.8vdc @10A CC BEC or 20A CC BEC PRO a simple resister for final adjustment below 4.8vdc. BEC ( Battery Eliminating Circuit )link

Servos to open / close thinges like active grill use pulses width modulation on signal for position or can be hacked at the position pot. As well as liner actuators for heavier applications eg Active extended boat tail diy-active-rear-aero- link


BLDC / BDC Motors and controller RC Esc (motor controllers) includ a BEC
Forward only from avation (something that self-deploys and pi brings in @xxmph)
Forward /brake/reverse ,(force open hold force closed) Forward / reverse car, boat
Motors to replace or upgrade BDC With BLDC or vica verca eg fans ,ac Blower motors ,wipers ,power windows, ect,ect
avation motor link
land motors up to5kw 85%+efficiency
Even water cooled this is only 1 manufacturer, their are too many to shake a stick at
lets Have some fun with our hobby that if dune right, will fattens our wallets.
Gumby stay flexible.
