![]() ![]() They also revised the motor assembly to allow for PWM fuel pump control or standard +12V. Walbro Engineers based the overall design on the same 39mm motor from the proven 255HP but changed from the old “gerotor pump” to a high performance “Turbine pump”. Designed to reliably meet the fuel-hungry demands of turbocharged gasoline high performance engines, this pump is remarkably quiet and heats fuel less, due to the turbine rotor design. Walbro’s 450 LPH “turbine style” in-tank High Pressure fuel pump is the single highest flowing Intank pump we offer. The conservative horsepower rating of this pump is that this pump can support 800 HP on 12 volts and up to 950 HP on 13.5 volts!!!!!!! All pumping components have been validated to OEM Specifications for approved use in E85/Flex fuel applications. OEM technology designed and developed for E85.Designed for engines with more than 500HP.Outperforms all current market in-tank fuel pumps.Included hardware is not application specific. Includes Fuel Pump, installation instructions, wiring harness, pre filter and o-rings. For example, the Tephramod v3 ROM ID 52680 322 will work the same as the standard ROM 52680 022.ģ20lph E85-Compatible High Flow In-Tank Fuel Pump (65mm Short Offset Inlet, Inline). replacing the third to last number from 0 to 1, 2 or 3). Note: These will work with the Tephramod v1-3 versions of these ROMs (i.e. Open "Secondary Fuel Pump - Load Hysteresis" to edit the hysteresis of the trigger.Open "Secondary Fuel Pump - Load vs RPM" - Set the load points for when you would like the secondary pump enabled at various RPMs.This will trigger the intercooler sprayer light on your dashboard to turn on when the secondary pump is being fired. (Optional) Open "Secondary Fuel Pump - Intercooler Sprayer Enabled" and use the "+" and "-" keys to toggle whether or not you want that feature enabled.Open " Secondary Fuel Pump - License Key" and enter the License Key that you generated.Open "Secondary Fuel Pump - Function Call", and press the "+" sign to make it say "Data Present".Open "Secondary Fuel Pump - Data", and press the "+" sign to make it say "Data Present".Scroll down until you see "Secondary Fuel Pump".Launch ECUFlash and open your ROM file.If the file won't save, be sure your have Administrator rights to that folder. Before the "" closing tag in the end of the file, paste the text from the downloaded file by pressing CTRL+V.In a text editor, open the XML file that matches your ROMID in following folder (note: this may require Administrator permissions on your PC): "C:\Program Files (x86)\OpenECU\ECUFlash\rommetadata\mitsubishi\evo".Select all of text in the file by pressing CTRL+A, and copy it by pressing CTRL+C.Open the downloaded file in a text editor such as notepad.Download the appropriate XML for your ROMID here.Note that this will require your VIN number. Go to this website and generate a license key with the coupon code that you were provided.Connect the blue wire to 86 on the relay and the red wire to 85.Run the wires through the car to the relay which controls the secondary fuel pump.Plug the provided cable into the black connector which was originally connected to the black 2-port boost control solenoid.The secondary pump should not automatically run when the car is started. A secondary fuel pump must be installed and wired up with a relay.The car must be an Evo X, this specific kit will not work on a Ralliart.The factory 2-port solenoid which uses the black connector must be unplugged.The car must run a 3 port boost control solenoid connected to the brown connector.The kit includes a plug and play connector and a software patch for your ECUFlash ROM. This kit allows tuners to trigger a secondary fuel pump based on load using ECUFlash. We teamed up with ripnet and came up with a great new solution. It will often require another bung welded into the intercooler piping, extra wires and hoses running through the engine bay, and it's just not as tidy as most people would like it to be. Do you have a dual pump setup in your Evo X and wish you had a good way of triggering the secondary pump? Traditionally, people have used a hobbs switch for this purpose, and while it works, they can be unreliable and a bit clunky. ![]()
