.....huh?

the way it works is. say you hooked up the wastegate directly to a vac. hose from the intake manifold. or hell the compressor side of the turbo. the what ever the stock spring is set at the waste gate will open at that setting.

so i have two turbos one is a t-25 with a 12 psi spring and the other is a t-04r with a 15 psi spring

say i just swapted to the t04r and i still wanna run no more then the 16 lbs of boost that i ran on my t-25. my boost controller will think it has to limit the same amout to get 16psi from a 15psi spring as it does with the 12psi spring becuase it has no way of knowing that i changed the turbo.

see what i'm saying. now if it had its own boost sensor then that would be diffrent

 

Hmmm...I think I know what you're saying...but I don't get one thing.The WG has two ports, if I was only to use the bottom port, then when the pressure built up underneath, the spring would be pushed open, therefore lett exhaust through the wG, correct?

however, when I hook up the EBC, I connected a line from the solenoid to the top of the WG, therefore the solenoid was applying the boost to the top of the spring as well as the manifold pressure to the bottom...keeping the pressure difference nuetral. What I thought happend was when the BC decided it was time to open the WG, it simply stopped allowing equal boost into the top port of the WG.

Is this what is happening? And if so, why can't the computer of teh EBC just KNOW that at 15 PSI, close the solenoid, open the WG...wam-bam-thank you maam....15 PSI is 15 PSI (in this case)...

 

....hrm i've never seen a set up with two lines

 

Ummm....well then...maybe because I'm external WG and you have only seen internal?

 

i dunno my roommate has a tial wastegate. i want to say its only one line

 

I have an Innovative Progate, but I thought they were ALL two line...now I'm even more confsed...thanks dick...lol...j/p.

 

external gate w/ electronic boost controller uses two lines

external gate set up with manual boost controller uses 1 line.

 

yeah what he said. haha thanks for clearing that up. yeah were all using manual controllers now. the e-01 will be installed on the tial gate once everything is together.

 

I just bought my E-manage. I should have it in and tuned in a couple weeks. I'll let ya'll know what I think of it then.

 

i think it ran pretty well, spite the fact it was'nt masking the ecu from seeing boost. what im trying to get at is there is a recall for all 96-00 sohc greddy e-manages boxes. its been 3 weeks and im still waiting for mine back.
