Thought i would post some info on my WUR tuning.
My car has always run rich and is quite smelly so i have now invested in an adjustable WUR.
I have made up some pressure gauge test lines to check fuel pressure and a gauge and supply line so i can add boost to the WUR.
The first task was to check the pressures of the original WUR:-
ORIGINAL WUR ( Warm fuel pressures are on the richer side of the tolerance 3.75 +/- 0.2 bar and boost came on too early at 3psi/0.2 Bar)
SETTING
COLD 16 PSI / 1.1 Bar / 0 Bar Boost
WARM UP 48 PSI / 3.4 Bar / 0 Bar Boost
BOOST ENRICH 39 PSI / 2.7 Bar/ 0.8 BAR Boost
THRESHOLD 3 PSI / 0.2 Bar
Adjustable WUR (set up to leaner side of factory specs)
SETTING
COLD
WARM UP 56 PSI / 3.9 Bar / 0 Bar Boost
BOOST ENRICH 44 PSI / 3.0 Bar / 0.8 BAR Boost
THRESHOLD 6 PSI / 0.4 Bar
Now all i have to do is drive the car and check the AFR's. Will update once i have the figures.
