Booster pump control unit

Booster Pump control unit 

When designing the booster pump, we analyzed the potential load on the main pump's power supply circuit. The OEM ECU easily powers the main pump and allows for temporary powering of the booster pump. There were no signs of pressure drop at the injector when the booster pump was engaged. Personally, I can ride the rear wheel in 5th or 6th gear, let alone off-road. The original KTM ECU has no problem powering the booster pump. 

However, we encountered a customer's KTM 350 motorcycle where the GET ECUs weren't efficient enough (a bug in the controller or software, regardless). This is one of the reasons why a second hole in the tank was necessary. This is precisely to make the booster pump power independent and avoid burdening the accessory ECUs, which, in our opinion, were not well-designed (I assume the accessory ECU should have the same parameters as the OEM and be better). What is the reason for this, and what did the designers miss? I have no idea, but two such cases have already happened (both GET ECUs).

If you also have one, you may need to use this Booster Pump Control Unit, which is the simplest system in the world, using only a normally open relay. The positive and negative connections that went directly to the booster pump are now connected to a circuit breaker (current consumption is only 150-200mA), and the positive and negative connections to the booster pump are taken directly from the battery and ground, and the positive goes through the relay in this case (a fuse is a good idea as a precaution). If you look closely at the photo, you'll see that there are actually four wires. The system is based on the simplest commonly available relay (12VDC, 20A). You can easily make one yourself or buy one from us. If you have any questions, we'll be happy to answer your questions by email.

Why is a booster pump the best? Because it's prepared for any situation. Nothing will surprise you! In the first version, we wanted to keep the design simple, but these problems forced us to redesign our solution. At the time, I didn't realize the problem was a lack of voltage at the pump's OEM power supply. I assumed it was the gasoline intrusion that was damaging the pump's electronic control system (that yellow box that's now outside). The accessory ECU was responsible for all the problems.
