Series 2 On Boost

make a jaycar boost contoller

i've still got to install mine cos im slack

I did the solonoid mod on my series1 stagea. Before I did that I just bypassed the solonoid by joining the two pipes together using a 5mm connector. Loads of boost but spiky and the car didn't really like it so I reckon that the solonoid itself must have a restriction in it even when it is open. I reckon that if I had tried a 3mm connector the boost might have been a bit less spiky and more controllable but in the end I just plumbed it back into the solonoid and earthed it so it is open all the time. I suppose the next best thing would be to get a boost controller but which one? A manual boost controller seems to work by limiting the pressure on the waste gate actuator with a ball spring valve whereas electonic ones work by bleeding air away from the wastegate thus increasing boost and they open and close very quickly to keep the boost at the right level. Not sure which is the best method.

jaycar one uses a solenoid but its set up that it blocks any pressure to the wastegate when closed so you get the fastest possible spool and once you reach your target boost level you open the solenoid up to let some air to the wastegate

the jaycar also runs 2 independent maps which means you can have one that boost comes in slowly and one that gets boost on as quick as possible both with the same psi but with different ramp on rates
