hey guys,

i have a Greddy E-01 boost controller in my car

its weird but i can't get it to boost past a spike of 8.3 psi

could this be because the solenoid is bad...the fact that it went past 7 psi makes me assume that i'm not just running off the wastegates, is a this a correct assumption to make?

is there a way to test the solenoid to make sure its working?

help would be much appreciated

thanks,
VJ

 

are you using stock intercooler piping?

first check behind the intercooler, the S shaped rubber pipe and the crossover tube for cracks

 

This is on that custom twin setup?

Two wastegates correct?

If you look at it from the middle, there are 3 ports. the middle one is your normally open (NO) port. The right one normally closed (NC). The left one is the common port (COM). air should flow from the middle NO port to the COM port. When you apply +12V and Ground (you could use a 14V drill battery) to the terminals of the solenoid connector you will hear the solenoid click. Air will now flow from the NC port to the COM port.

It is unlikely that the solenoid is bad. It is highly likely that you are confused with how to use the controller or how to route the lines.

Read this thread, which talks about how this type of controller works. https://www.rx7club.com/3rd-generation-specific-1993-2002-16/electronic-boost-controller-comparison-chart-952767/ . See the Greddy E-01 on the chart in post #2

 

no not yet...the car is going in next week when my fabricator gets back from vacation to get the turbos put in

i was testing all my electronics to make sure it all worked, and i saw this issue

 

ok great, i'll be check this asap to see if thats what the issue was

thanks
