Hey guys,
Haven't had any drama's up until recently, but all of a sudden all sorts of issues.
Car was mapped on 23psi peak with 21psi taper no drama's about 12m ago.
The past month, now as soon as boost hits ~22.3psi, the car slams violently forwards, like a boost/fuel cut.
When this happens, the Defi boost gauge will spin back from 1.5bar to 0 then backwards again etc.
Now the curious thing is there is plenty of fuel, walbro pump and the injectors are only ~85-87% IDC, there is NO KNOCK at all when this occurs (15counts or less)
I wasn't aware the PFC had a boost/fuel cut of sorts??? Or am I wrong?
I've pulled a degree and added 3 counts of fuel across the whole map, still the same problem...
Am running a Blitz id3 EBC, which i've had to fiddle around with lately as its spiking stupidly in the cold, even with teh gain on like 7 instead of 12 it still spikes 1-2psi at 20.
Have swapped ignition leads with another working set, and have new plugs gapped correctly....
Any more ideas? doing my head in! Can i check the coilpacks with a multimeter?
BTW, its an Evo 7 which runs wastespark setup on 2 coil packs, i'm posting here cause theres alot more knowledge on PFC here.
Cheers guys
Ben
