Firstly, are there any ecu's on the market with an in-built fuel pump controller? Something that will regulate the voltage at differeing rpm, so the pump isnt running full noise 24/7 and heating up the fuel.

Main concern is big pumps in street driven cars.

I know aeromotive do a unit, but its only a 2-step i.e only regulates voltage based on 2 rpm inputs, well thats my understanding of how it works. Is there anything out there that gradually increases/decreases voltage in relation to rpm?

If you run a big pump/s, how do u combat this?

The ViPec/ LINK G4 just use two auxilary outputs. They are configured as fuel pump for one, to switch on, and the other is configured as Fuel Pump Speed. This is activated when a set revs is reached (and or %Inj Duty cycle ).

The switching obivously needs a relay with a resistor inline with the pump to be able to switch it in and out as needed. As in most factory efi setups for the last 20+ years.

You could use an aux output set to pwm to control the pump that way, but you would still need an external driver (ie ignitor module ) to drive the heavy current loads a pump would use.

Show me any ECU that can control pump speed out of the box directly.

And whats so hard about a relay and resistor ???

yeh thats the way i meant, use a pwm output to control the pump via a relay and resistor. in the haltech its got a 32x32 map for it aswell. need to discuss it with my tuner though

If you use PWM you won't be needing a relay and resistor, just an single channel "ignitor" would be necessary to controll the large currents possible.

The link can quite happily do this and has a 3d map based pwm outputs as well.... and you can specify what ever you want to be the axis's of said 3d map .... boost*rpm or %inj duty*rpm ect .....

Any ecu will need an external ignitor channel to control the pump.

So...... no need to ditch the Link/Vi-pec

Seriously, its really an impressive bit of gear.

      Anyone know what this front bar is for series 1 R33??

      Edit: It's now known as "R Performance" and is still in operation.

      This lady loved her FD for 25 years!  https://www.topspeed.com/80-year-old-woman-donates-fd-rx-7-mazda/ My brother in law. He's nice enough to let me drive it whenever. He'll likely not see this, but I'll try: @r-is-for-fun got any pics?

      Just something I found searching for more info on Emotion R, apparently the ECR33 Skyline GTS25t was either originally black, or there were two of them, the black one being the original demo car, then building a white one which was part of the 1997-onwards (to at least 2008!) Cockpit Tatebayashi Tokyo Auto Salon booth demo cars. It appears that Emotion R closed down in 2008 and was declared bankrupt in 2010: http://bank-db.com/hasan/208365. Scan of a magazine with the black R33 from 1996: Wayback machine archived page from May, 2000: https://web.archive.org/web/20000529061027/http://www.emotion-r.co.jp/skyline.html Option magazine with a few photos from the Cockpit Tatebayashi booth at the Auto Salon from various years: 2002: http://www.jdm-option.com/photo/index.php?action=item&category_id=154&image_id=3507 2003: http://www.jdm-option.com/photo/index.php?action=item&category_id=137&image_id=3033 2005: http://www.jdm-option.com/photo/index.php?action=item&category_id=116&image_id=1831 In 2008 Cusco website mentions that the Cockpit Tatebayashi ECR33 was displayed at that year's Tokyo Auto Salon: https://www.cusco.co.jp/event/2008/12/post_735.html As of 2021 it appears that the ECR33 demo car ended up being exported to Florida, USA: https://rmcmiami.com/inventory/1996-nissan-skyline-r33-cockpit-tatebayashi-demo-car-big-te06-turbo-endless-brakes-lsd-450hp/ And finally here's Google streetview of the Emorion R garage in 2023 which is amazingly not only still there, but the showroom is still full of various parts in stock and funishings, etc.: https://maps.app.goo.gl/ttyEAZdZLyzermyT9 Apologies for nerding out a bit. I used to love doing this 20 years ago on SAU and got a bit nostalgic for a moment... 😅

      Try fabricating something like this and install it under the pedals? Not sure if it's legal or not....
