Default Re: failsafe problems

There are a few uncertainties for me:

1. After you changed the fuel injectors, it also alter the resistor pack circuit unless the previous injectors are also low impedance.

2. After the Hydra, it could also change how the hydra see the new injector + resistor pack.

To clarify all this for me, you need to do the FDC reading so I know what the HFS3 is seeing.

Default Re: failsafe problems

Did some driving this afternoon heres what I found with FDC jumper in-

Failsafe light constant
ticking from controller (relay I assume)
Closed throttle idle nothing illuminated
as throttle opens "s" flashes then turns solid and bars start to show
"B" seemed to flash as I was maneuvering
did WOT in second and third and was able to show 6/7 bars depending on how long I kept my foot down, looks like if I had enough space I could fill all 8

have had nozle tapped into a container and it did srpay slightly

It looks pretty good. You are using 60-70% of fuel. The system can make up the rest by the "GAIN" trimmer on the controller.

OK we can move on from here:
(after removing the FDC link)

Please tell tell me of the following:

On the controller:
1. The setting of the "THRES" and "GAIN" trimmer
2. Size of your nozzle.

On the gauge:
3. SC, WH and WH. positions

I have many nozzles, am using a 0.6 until I have it mapped when I may go up to 0.9

All of my trim settings both on the controller and gauge are at 12 oclock default setting

The 0.6mm jet will not be showing on the gauge until you have solder linked the flow table. The default flow table of for 2 jets.

I suggest trying the following settings first:

WL/WL.......fully CCW/CW
SC ........ fully clockwise
THRES ..........9am.
GAIN .......... 3pm

Clip the jets on the screen so you can see the spray.

You will get a failsafe problem since the jet is far from the correct flow table.

Ok I'll try those settings tomorrow, thanks

I chose 0.6 because I dont want to add to much water before its mapped for it?
Is this not an issue? Can change jet size if it would make things easier

im only running one jet, about 6 inches before throttle body

Yes, changing the jet size to something like 0.9mm will be better. I think flow table 2 (default) can read this quite happily. No need to solder link.

It is unlikely the temperature will drop below zero so 100% water will be fine. Clip it on the windscreen first.

Default Re: failsafe problems

Set up trims today and done testing
had to turn "sc" on the gauge counter clockwise a few clicks to get flow in middle

failsafe light still on
upon build up of boost/FDC the failsafe light turns of and bars fill up to 4/5 and the "b" lights up
the spray from jet is good and increases well with boost/FDC
As I return to normal driving the failsafe light turns back on

Default Re: failsafe problems

Is the failsafe led on all the time or just come on when spraying?

Just to be clear:

Are you saying the failsafe lled is on all the time and goes off under boost?

Failsafe trip = both yellow leds
Water level trip = one yellow led.

Let me know which the above.
