ok have tried to do alot of research on this particular fmu. i never recieved the manual for this setup as i bought the car as is. its a paxta programmable fuel map curve box for my paxton sn2000 blower. first im not sure if this is a signal modifyer or if it is its own circuit. i always thought it was hooked inline into the ecm. i believe it senses boost from an extra map sensor mounted on my firewall for its own use only - then fires the 3 extra injectors at the throttlebody under boost. the leds on the box then give a visual as to how much boost/fuel is added. others have told me it gets its inputs off the msd 6BTM setup since this unit has a map input. im totally confused someone please help! thanks
