Re: failsafe problems
I have now moved red wire to ecu harness and tested, still getting same issues but now it wont spray*whilst driving, with the jumper in f-idc the gauge showed 2 or 3 bars on half ish load still nothing on idle, didn't get a chance to do wot, but the f-idc led still flashes
do I need to relocate the green wire from grey ecu loom to a ground source or should it stay on the negative wire of the injector plug? |

Re: failsafe problems
I think the wiring is now correct. Can you clarify jumper on f-idc, do you mean FDC?
I think it is important to see what the bar reading is at WOT with the FDC linked.

Re: failsafe problems
Sorry yes mean jumper on FDC, I'll go out again and get a wot reading before I go any further, if it comes out low will I need to solder x1.5 possibly?
I have gone from 540cc standard injectors to over 800cc ones. |

Re: failsafe problems
If the FDC only shows 4 bars max at WOT, you then need to solder x1.5. If you are not confident in soldering, i can do it for you, just send the controller to me.
What is the estimated power of your car? I can guess the FDC% is you are concerned doing WOT on public roads. 3200cc/min is good for 550-600bhp.

Re: failsafe problems
Ok thanks, I'll have a look at the board and see what I think about doing it myself
only running around 400bhp but engine hasnt run all winter so just easing it in really! I'll get a passenger to read gauge properly as I do wot and see what results I get, ideally do I want all bars to light? |

Re: failsafe problems
Also running satand alone hydra nemesis ecu if that makes any difference?

Re: failsafe problems
Thanks for a much needed info, That makes a great deal of differences.
The Hydra has "peak and hold" driver (AFAIK), resistor pack is no longer needed. Please check and confirm. If you can not using a resistor pack, the F-IDC signal will be "peak and hold". All you need to do is use the green harness, connect the red and green wire across the injector.

Re: failsafe problems
Im not sure how i could check that, the ecu plugs directly into original loom so the wiring to injectors is standard
So ill be using the green "user" harness to read fdc? |

Re: failsafe problems
Not yet. Not until you have done the FDC/wot test.
One thing you can confirm for me: are you using the resistor pack for sure?

Re: failsafe problems
I cant see how im not unless im missing something, the hydra was almost a plug and play, no wiring was changed or altered
So the injectors are still receiving the signals from ecu through the resistor pack? I can ring my mappers and find out for sure, but I know 100% that the resistor pack is still there and wired in |
