im changing my efi erst from ofac to ofab but some diagrams ive found show that i need a suppressor between 1 of the map sensor wires and the ecu,ive found another diagram which doesnt show anything about a suppressor,im using an efi xr3i loom

 

anybody know if i need the suppressor

 

Theres a suppressor that sits on top of the coil pack if thats the one you mean?

 

no that only has 1 wire going to it,the item im trying to find out about has 3 wires and is to do with the map sensor
