right reset the unit went out for a blast and it hits 0.93 bar. so set that as baseline boost.

 

wastegate set to swing type, set target boost to 1.2 bar. left the correction coefficient at 100%.

 

now can't hit the set boost of 1.2 bar. most it will do is 1.07.

 

tried playing with the offset but doesn't really seem to do much even at 150%.

 

wonder if i need to redo initial setup and raise coefficient at bit.

 

worked fine this morning could easily pass 1.3 bar if i turned it up. should have left it alone!!!

 

ffs.

Solved, it was the coefficient in the initial setup. Raised that slowly in 5% increments until I can constantly now the desired boost. It now spikes to 1.32 (as with Scott C above) and drops back to a steady 1.2bar. It was fast before, but now its insane and the lag has massively reduced. :D:D:D:D:D:D:D:D:D

 

downside is thats a quarter of a tank gone :D

Hey man, I have an evc 5, just about to install and my instructions show the only one of the 2 nipples on the vsv get capped(one clodest to motor) and that a hose from (B) on my solenoid runs to #1 in your pic and 13 and 2 get capped?
