Default 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?

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.

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.

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.

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?

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.

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?

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?

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
