need a good fuel pump controller working on a friends car, he has an aeromotive controller, what sucks about it is that it is a one step change and it is on a static rpm set point.
this sucks for a turbo car. i need a controller to run a 1500 pump that will be at a minimum user set speed, and progress linearly with boost to a full speed.
the closest thing ive found is a snow meth controller, but the minimum speed on that occurs at a minimum of 1psi boost, so it will not run under vacuum.
any help?
thanks.

aeromotive is pwm to cut the speed by a whopping 20% (woooow) at rpm's under your one set point (on the dial with no increments)
yes i could trip the aeromotive to full speed lots of ways, thats not the end of the spectrum im looking at.
i want to reduce pump speed by at least 50% under idle and vacuum situations and LINEARLY progress (like the snow meth kit) to full speed at the boost level i pick.
this is a < 400ci 1300 horse set up and i need it to be very dependable and 'nice' on the street
if i could have my way i would throw the aeromotive 1500 pump in the trash and dunk a few walbro's in the tank

The Aeromotive 16302 speed controller drops volume by 40% when its running on the low side. You have the option of rpm or ground to select the high side drive.
The Aeromotive 16303 speed controller adjusts pump speed based on MAP and is scalable for most applications. Why anybody would need to do that on a return system is anyone's guess.

the 16303 is a very expensive version of the snow meth controller, the same problem with it is that it only runs at all under boost. where i need a minimum speed to be present under vacuum situations.
the reason is i have a 1500 horse pump on the car and i do not want to be running 1400 horse of fuel up across the motor and back cycling a full tank of gas every 5 minutes... not to mention i may run into a problem not being able to drive the fuel pressure as low as i want (to get injectors stable at low rpm) because my regulator or return system is maxed out.

Why do you feel you need 1500 hp worth of fuel on your turbo car at low rpm or low boost, or more to the point why isn't 900 hp worth of fuel enough until say 3000 rpm?

no i havent measured anything, i assumed the manufacturer knew the specs on their product. were they wrong? or are you saying a 20% decrease in speed = 40% decrease in volume? i would like to see the graph on that.
maybe you are reading me wrong i DON'T want full pump speed at low rpm or low boost and 900 is still TOO MUCH to have cycling through the car.
again
i am looking for a pump controller that will run from some user selected minimum to full speed vs user selected boost maximum, and obviously i need it active (at the minimum speed) during vacuum condititons
if this doesn't exist it should, it would be the best solution for this cars fuel system needs

I'm not aware of any published specs from Aeromotive on the 16302, I am just trying to convey to you what the controller does measured on Aeromotive's own pump flow bench while the pump is operating under load. 900 hp worth of fuel is about 75 gph or what an average A1000 will put out, or even a bit less. The A1000 is considered a durable street pump and acceptable to run without a controller on an LS1 motor with a composite intake manifold and aluminum rails assuming your fuel lines aren't plumbed next to the exhaust.
Aeromotive has a fully digital programmable speed controller that is user mapable, but its not in production yet. I have used a pre-production model that's in daily service and it will be a nice piece when released.

Any idea on the price of that unit when its ready????
Like i stated above.... im not having any problems with the controller or the Proseries pump.... its been going strong for thousands of miles....
David where do you have the base FP at and do you have it boost referenced??? What FP Reg you using..... Aeromotive Proseries Reg here....

No I really don't know where pricing will be, I'd refer you to talk Jeff at Aeromotive regarding its status, I would think it has to be ready pretty soon. Maybe they applied for a patent or something, those can take some time.

i was talking to brad up there, i had heard about the new unit comming out but he cannot meet my project deadline.
background info:
i am working on a fox body with a gt-47 on a Duttweiler engine (street car)
it is an eliminator pump (not a-1000) -12 sump inlet, -10 pressure side split to -8 to each rail
-6 off each rail to an a-1000 regulator to a single -6 return
fp is referenced, and i would like to set it up to run as low as possible to give the injectors lots of room at idle and cruise, and give the fuel pump lots of room for when we turbo-up later.

David i really dont see why your having problems idling the car and cruising/low RPM...
WE were told my Aeromotive that the Elim. series was to small for even my old GT42 turbo power/fuel wise....went with the Pro
I have the same feed as him, but i have -8an off each rail to the Pro series Reg to an -8an return
My base FP is set at 38 psi and my 96# injectors have no problem down low... 900 rpm idle....
Ya got me wondering.....

not having a problem, trying to prevent a problem down the road. since i have no idea how long this car may idle, sit in traffic, or cruise for i am trying to play it conservative and treat everything like what I would do if it was my car.
*edit* if nothing is available then i will have to be putting the original 2 speed box back on and just see how it goes.

We had bad luck with the controllers and overheating pumps.
A common solution we do is run 2 pumps (420l) with 1 running all the time and the other boost reference with a bypass switch for the track.Been dead reliable and extremely quiet.Can handle 1000rwhp through an Auto no problem.(maybe more)

I've run that same set-up for two years without a problem. Pumps are in the tank so it's quiet also.
