failsafe problems ::cause found::
Just installed a hfs-3 system and having failsafe issues
After starting the car the system starts up as it should and dispays everything on the gauge, the green idc led on the controller flikers with engine rpm. purged the system and linked "sys" and it sprays just fine, test drive done and it also sprays and shows bars on gauge. but the failsafe light flashes all the time even though the tank is full?? any help would be appreciated |

Re: failsafe problems
Can you put the jumper link to FDC (use the PRK) and tell me how many bars are displaced on the gauge as you go WOT.
One question, do you use low impedance injectors?

Re: failsafe problems
Ummmm id have to look back at receipts ive got aftermarket 890cc injectors, 90% sure there still low impedance
cant go and do wot right now cos its raining cats and dogs! But with fdc linked at idle its shows no bars on the gauge, if i rev the engine to around 4k all i get is the s flashing?? |

Re: failsafe problems
If the system is not seeing fuel flow, you probably have low impedance inject or you have a resistor-pack in series with your low impedance.
Before you do the following, check out which is which and post here. If you have low impedance injectors without resistor-pack, you need to use the green harness. Green harness: Rewire the red and green directly to you injectors. Grey harness: rewire the red wire to a 12V source at "pre-crank" and "run" key position. Richard

Re: failsafe problems
Ok thanks for that, ive definitely got a injector resitor pack because I had to buy a new one lol, ive wired red directly into injector + and green directly into injector - using the grey ecu harness

Re: failsafe problems
In that case. It is a simple fix.
Relocate the red wire (grey harness) to the other side of the resistor pack where all the resistors are tired together.

Re: failsafe problems
Ah ok, so just wire into any injector + signal from ecu to resistor pack not resistor pack to injector like ive done?
thanks for your support big help! |

Re: failsafe problems
Yes, it should fix your problem and the S led will not be flashing at high load.
The red wire has to have a stable 12V. If you wire it on the injector+ side, the 12V is partially pulsed. More so at high load.

Re: failsafe problems
Ok brilliant, I'll re wire during the week and try again :-)

Re: failsafe problems
This is not a failsafe problem.
The failsafe has identified a problem.
