Default Runs pretty good, room for more? - 10-24-2020, 09:38 AM

So after double checking the 2 step wiring and realizing it wasn't correct, I fixed it and the 2 step is still not working. Frustrating.

Attached are runs in map 2, map 5 and map 5 with E30

The first thing I see is that it is reading E22 when it should be E10 and with E30 it read E40. The vitrual offset is 140 right now. I am thinking it should be changed to 130 Yes?

Both the high and low fuel pumps look like they are not even close to maxed out. I am wondering if I can build a Map 6 from this data and increase the boost?

Is there a way to see in the log if you have a leaky injector?

If I try to cruise around 3000rpm the car bucks??? Any ideas

Anything out of the ordinary you see?

Looks like a small boost leak maybe ?

Because boost is below target by more than 2psi?

Because FF is at 150 and wgdc in the 60s to make 13/14 psi
Maybe vaccum ? Or solenoids ?

So the duty bias setting were set at the default for hybrid turbos. You dont think they might need adjustment?

Ok well i had replaced 1 of the 2 boost solenoids that i knew was dead. It was just a matter of time til i replaced the other. It is ordered. I will check the connection at the front turbo again (wish i had clocked that turbos slightly) will update when i have new logs.
