I'm having doubts it's the solenoid itself. as it regulates boost the way it should. just overboosting in low gears is my issue :s

I've ran the text function on the Eboost2 and it operates as it should.

Thom

Theoretically it makes sense. May be worth a try.

Paulyy

I wouldn't mind upgrading my wastegate anyway as i want to change it to Vband because the adapter plates have slight little leaks as it's been removed a few times, and it'll eliminate gaskets (which caused a boost creep as the bolt came out and gasket moved down and blocked the wastegates flow path)

It's something i can think about doing

Thom

Have you tried to reduce Gate Pressure until getting rid of the spike in 2nd gear?
Said differently, have you tried values for GP lower than 11 psi, and does it make a difference?

i will have to lower it to at least 10 psi, i'll do this friday as i now drive the car on weekends mostly.

I understand his post. it makes sense, that's how i did mine, but it was in 3rd gear.

I'll do it and report back. Thanks for your help

Pualyy are you sure your lines are not getting pinched or they are collapsing? that will cause exactly what your describing now that i think about it. It happened to me

Paulyy

I've looked into that too, they're actually fuel lines and they don't kink.

Paulyy

I've gotten down to 9psi got the gate pressure. and it still overboosts.
I am going back to dualport as i never went this low before and test it on that.

Paulyy

So i changed back to dual port. put the start boost (gate pressure) at 0 and it boosts like it would boost with a MBC.. im guessing because it's already regulating boost when it sees 0.1 psi and no overboost so far and it was raining which means moist cold air (where it over boosts the most).

So far so good.

NICE

Paulyy

Carlos what settings do you use on your Link for the solenoid?

reno808

on the link it self or the how i plumb on the boost solenoid?

Paulyy

On the link itself.

Thanks

boost Mode: Open Loop
rpm activationL 2000 rpm
map activation: 100kpa
Deactivation Timeout: 0.0secs

Let me know if you want to the boost table and trim tables.

Paulyy

Thanks for that.

100 kpa as in 0 psi or 14.5 psi?
