Love my LS kit. Works great so far!
Will the system function properly if the knock sensors are deleted?
Yes the knock sensors can be deleted.
I was told I did Not need the 70002 trans as I’m using a Tremec 6 speed is this correct
yes
will the FiTech Ultimate LS EFI 500 HP Fuel Injection Systems 70001 work with a 700r4 trans? Do I need to run a TCM?
FiTech Ultimate LS EFI 500 HP Fuel Injection Systems 70001 - will this system work with a 700R4 trans? Do I need a TCM?
is there no oil pressure sensor? i just wired up my kit today and couldn’t figure out why there wouldnt be a wire for it
The computer does not require oil pressure to fuel the engine therefore it was left out.
what cable goes connected to the battery
Will not having engine grounded to frame have system running issues?
Yes, Grounds are vital to our EFI system.
My kit has been a total nightmare... everything is plugged in and done professionally and the damn thing just backfires and hisses while cranking....
Back fires during cranking will come back to a firing order issue. Chances are you have the coil harnesses backwards of flipped over. Make sure you have the subharnesses on the correct bank. Driver to Driver and Passenger to Passenger. Also make sure Cylinder 1 coil 4 pin plug has a purple wire in the C location and that Cylinder 2 coil 4 pin plug has a red wire in the C location. If not then then the harness is flipped over wrong.
@@FiTechEFImedia verified correct bank and used 2 different harnesses. Fitech also said my ECU and harness is good to go after inspection.. frustrating...
Does this system have paddle shift control ?
The ultimate LS does not support paddle shifters.
I really don't understand the brake switch wire. How do I hook it up and where?
I goes to a brake switch as long as it is the correct one. It is looking for 12 volts when you press the brake. Zero volts off the brake. AC Delco part number D850A would be an example of the swtich needed. You can also use a relay to flip the signal of an older type switch.
My god I messed up buying the Holley kit. Was told by the guy at performance plus to not buy this kit. The Holley kit is a joke. 3,000 and no harness for the alternator
For FJ40?
2f engine?
any 4,6, or 8 cylinder engine. As long as the ignition system is a 12 volt system. No balast resistors.
Where exactly does the key on wire need to go
The exact location would be the ignition switch in the ignition position.
