At full load, the pump will draw about 16A.
Really? A 200 watt pump for FUEL? That is over 1/4 HP!
The standard in tank pump is PWM controlled by the ECU. Replacing it is expensive with most solutions costing about £700-1000. As the engine comes on boost, the low pressure fuel system is caught off guard and causes a momentary drop in pressure on the rail. As the engine heads towards the red line, the fuel system then starts to struggle again.
Am I correct in thinking you have a faulty pump and are trying to find a cheaper work around ?Edit.Is your vehicle a Bently or a Honda by any chance
Hi,I've also read that H bridges don't like running 100% and are better suited at 95%?
That sparkfun shield is quite expensive.My unasked question though is whats the fuel consumption and performance of this beast.
