WI error on dyno but not on road!

[Wolf_Tm250]

Hi,
my system is HFS-5 dds3 v8, 2 x 0.5mm.
Any idea why I get WI error (with the wanted boost limiting effect) during dyno pulls, but not on road pulls??
I have plenty of water so it's not a water level issue...
Thank you.

How do you have the gauge spanned (SC setting)? Does it come on at about 2 bars and finish at 6-7 bars at redline?

When does the system failsafe happen, at the start of the pull or the end and what is the gauge reading when it does?

The failsafe happened many times at midrange, around 5000 rpm, when WI is injecting huge quantity...
Yes, bars are still from 2 to 6...
Is there a way to know if failsafe happens for a WL or a WH problem?
Thanks

The WL covers the left 4 bars and the WH the right 4. You would have to see what the unit is displaying when the failsafe trips.

Ok thanks.
Moreover during dyno pulls the WI failsafe comes on and off continuously and intermittently whenthe WI flow is at his max... so maybe is just a too narrow window problem...

Could be the WH needs to be adjusted a little.

Sounds like you don't drive your car hard enough on the road.
