Fail safe wiring
After a search and a lott of reading and re reading the install manual I think Ihave figured this out but need to make sure . The turbosmart Eboost street 40 boost controller has 2 boost maps that can be switched by grounding the switch wire .The standalone ECU I am using has 2 fuel/timing tables that can be switched using a ground in the ecu harness . What my understanding from the research is.In order to use the change over relay in the HFS-3 i would need to ground the white wire , and then use the brown wire to tie into the boost controller /ecu . This would let it switch tables when the fail safe comes on .
normal mode grd on boost table/fuel/timing table 2
failsafe mode grd off boost table/fuel/timing table 1
Is this correct ?
