[strictly]

Ok so i need help with the second picture.

it says if you cannot achieve the pressure at idle or full, then replace the throttle control regulator. Okay in my case, i could not achieve it at full throttle, so i presume its tits and i need a new one

BUT

my WUR is also tits (the heater dosent work). I havent tried testing it without the TCR also connected to it, i'll try that just to see what the current warm control pressure is (ive taken heater out - hence warm, no action on the plunger inside the WUR).

My understanding is the flow from the the FD is flowing thorough the TCR and the WUR at the same time, hence the 3 bar, when you turn TCR to partial throttle, it closes the plunger on the TCR (its open at idle and full throttle), and there is no flow at partial. Therefore only the WUR is regulating flow at this stage, which in my case is 3.8 (the TCR must allow the 0.8 bar to flow through when its open).

Remeber im trying to figure out what to set the warm control pressure of the WUR to. In the second picture, it clearly states if you cannot achieve the 3.8 bar pressure (i'll post the pressures too in a minute) then its the WUR at fault. As i can achieve this my WUR is fine (okay its not), but i think i can deduce that if i were to have the WUR only then i should set it to 3.8 bar (which it is, so i can actually just focus on the cold control adjustment) for warm, and when connected in series with the throttle control regulator, it would then get to the 3 bar warm we all know and love. I think that makes sense!

In my example above i'm at 3.8 which is the limit of spec, so of course i'll adjust it closer, im just trying to be certain that is the correct deduction.
