Setting up failsafe issues

[rbamon]

Hi all, I might be totally missing something here but ill explain.
Basically we tuned my r33 and went from 330 to 360rwkw with the aquamist and 98 octane caltex.
We set the SC to display 5 bars on the dyno, but how do you set the upper and lower failsafe settings? Should the lights come up as I adjust it?
Or do I align the potentiometers with the SC one and then 2 clicks either way respectively??
Iv had a look around for this but not alot has helped. Im sure iv completely missed something

Thanks!

Before making WL and WH failsafe window adjustment:

Make a mental note of the gauge readings. the max should be ~5-6 bars. Adjust SC if necessary.

Set the WL to 8am and WH to 1pm. Drive the car and to test the WH, if there is failsafe activation, adjust WH few clciks clockwise. Repeat until no failsafe activation is noted. Add two extra clicks clockwise. WH is now adjusted

Now set the WL to 11am. adjust trimmer counter clockwise until no more activation occurs. Add two clicks counter clockwise.

Watch the road.

Hmm, thats not real easy. full power lights wheels at anything under 150km/h.
Ill have a go. I thought this may have been the case but wasnt 100% sure. I had already set the SC to 6 bars on the dyno.
Thanks Richard

Also, if I set it back just one click, will it accidentally trigger alot? Its tuned on such a fine line I cant afford any loss of water meth, or is 2 hardly anything anyway?

I tried to set it, I set the scale to 6 bars, the WH was relatively easy to set, but the WL would not trigger the failsafe activation. I can go full scale either way and it wont trigger failsafe??

Not to muddy the waters, but this is how we set the failsafe : http://howertonengineering.com/tech-...dds3-failsafe/

Thats Helpful. I didnt think to use the full spray trigger with jet out and engine off.
Doesnt explain why I couldnt get lower trigger to activate by having WL at either end of scale?

The WL is setting the failsafe for when the kit starts to spray under light load. It can't really be set with the car stationary, you have to drive the car as per the web page.

I was driving the car when I was trying to set it though. I did understand however that it triggers if the 'max' flow falls outside the window, not when it begins spraying?
Whats to let you know if your jets a little clogged and its not quite spraying fully when your revving right out?

yup this is the info I used. Much easier to set the sc and wh.
