    solid state relays

    Im going to set up fuel pump running off a solid state relay and pwm controlled by the ecu. I cant seem to find the haltech ones any more and iv been looking at the jaycar 100amp. Is there any problems running a 25amp fuel pump on the 100amp solid state relay with a big heat sink?

    25amp? Are you sure it is not 25watt?

    25amp is fine on a 100amp relay. Those relays are not intended for automotive use. Dont know if that will be an issue. Also that one is very expensive. Put something like dc ssr into ebay. Should be around $10 with heat sink

    I used this exact relay to drive an 044 and a Walbro, just mounted to an interior metal panel with a bit of heatsink paste in between, works great

    I've used these in jet boats before. If they can deal with that shit they can deal with anything.

    Nice. What frequency Hz are you running it at? How have you wired it up? Still got a normal relay switched off ign for the power feed to the pump and ssr? Cheers mate.

    There is a fair bit of info including wiring setup in this thread. http://performanceforums.com/forums/...r+pump+control

    Next time I do one I will use a Subaru fuel pump controller for water pump or fuel pump. They are cheap and easily controlled and come with proper automotive connector.

    Cheers Al just what I was after. How much current can those subi ones take? I remember changing a couple of dead ones from GD8's that had o44's. Could of just been a coincident.

    I forget how I wired it up but i think it is powered by the Adaptronic fuel pump output (so the usual safety cutouts) and a adustable PWM output is the signal to modulate the pump speed. At idle you can have the pump running at like 20-30% duty cycle, *much* quieter and youre not needlessly cycling loads of fuel around. I also have another SS relay to run the water/meth injection pump

    Never had a problem with a subaru pump controller. The wiring in them is huge though, probable 5mm2. 044's only draw 14A too(advertised in Bosch catalogue).
    You can use the DI function on the controller to return to a Link/Vipec too so the pump duty is displayed in the software. Jaycar SSr's don't have this.

    Hella also do a solid state relay that fits a normal relay base and has a MUCH better switching time than the jaycar ones

    Just checked the datasheet for the SY-4086 from another supplier as the jaycar datasheet link is buggered.

    Switching time for turn on 1ms, off 0.5ms, that is SFA for driving pumps, even secondary/ auxiliary injectors isn't too much of a drama.

    Think I'll be buying one of these and the matching heat sink for my water pump at least, maybe fuel pump as well.

    they are rated to 80a on startup, I use one to run a pair of AU falcon thermo fans without any soft start, no issues at all 12 months on and the relay is cold to touch with the fans running.

    in practice they are shit for any kind of fine pump control!

    I have used them a few times on ewp's and they work fine.

    yeh because you need fine control for water pump or fuel pump..

    ahh yes for water injection or if your doing fuel pressure control with a motec.

    Ok..

    Funny how 1400hp rotarys can run perfectly fine off a m800 or ps2000 and a jaycar solid state controlling 12 of its injectors.. If there were that slow there would be apex seals everywhere...

    and how many of these 12 injectors running off the solid state relays operate at idle? where I'm sure a 1400hp rotary required fine injector control...

    test it for yourself... log the relay output with an ecu and compare it with the ecu output....

    Fine control my knob. I have used the SY-4086 on lots of cars and a meth injection.

    The system had 3 nozzles, pressure sensor [b]AND PID PRESSURE CONTROL[b]. The pressure was converted to flow rates for each nozzle and then to perfectly calculate the fuel to water ratio.

    They control just fine!

    I ended up using the 100amp jaycar ssr, rookie question but what is the correct way to choose what frequency to run it at? Iv got it set at 100HZ at the moment and it runs great off a 2d table of rpm vs boost on the vipec.

    100hz seems fine, given the figures thrown around for its poor switching.

    Yep 100hz is fine, remember that they are shit and switch too slow to be useful tho

    So what relay would be the go to run 2 aeromotive stealth 340s or should I run 2 separate relays.
    Looking at running a pwm signal from my haltech
