So 1 pump is triggered from the intake pump and the second triggered by the ecu or a hobbs switch? With both pumps constantly running I could see fuel heating isues?

I need to find out from HPT if the IMRC can be activated in a Turbo strategy. If it can I will be able to set up a single pump P100 tune and Dual Pump 85 tune and use the IMRC solenoid control to switch the relay for the second pump on when the E85 tune is installed Link to comment Share on other sites More sharing options...
