Mk4 Supra Fuel Pump Ecu Bypass at Curtis Edgar blog

Mk4 Supra Fuel Pump Ecu Bypass. You can test the oem fuel pump ecu by turning the ignition on and jumping fp and b+ on the diagnostic. It is not needed with 1jz supra ecus. What are the 2 pins in the boot wiring that need to be bypassed to start the fuel pump? The tt fuel pump ecu's basically take a 12v feed from efi#2 relay, then output either a 9v or 12v feed to the fuel pump ecu depending on if the stock ecu commands a low. I think it works on the walbro pumps though. The n/a fuel pump ecu isn't able to handle the extra current of the tt pump. This will force the fuel pump. This would run your fuel pump at 12v continuously. I was considering the 12v mod, to bypass the stock ecu, but that would mean the pump would run every time the ignition was. Paul, correct, bridging +b and fp bypasses the fuel pump ecu (fuel pump ecu controls voltage to pump, and also has the. I know it can be done in the diagnostic port but.
