How does the K04 wastegate/boost controller work?
#2
I'll have to look at my turbo again but one is for the for the bypass (probably 3) and the other runs to the solenoid on the intake manifold, which goes to the cold side charge pipe. If you're installing an aftermarket turbo all you need is:
1. Wastegate at diaphragm
2. To cold side charge pipe
3. Open

Gotcha. So it connects some where on the IM?
So the connection on the K04 boost controller uses a EV1 connection? So then you just need to find out how the PCM communicates to the boost controller. My guess is that it would be based of some sort of linear voltage signal.
You don't have a build thread started for this turbo setup do you? Cause I couldn't find anything.

i do have one, just not on here(mavens place-"did some work today"). and yes i believe it is linear voltage much like the LSJ bypass valve solenoid. there's even some nifty controls like steady state, prop speed and gain available in HPT. hopefully i can make it work just like a normal electronic boost controller.

Makes sense.
But you wont be able to control the K04 boost controller through the LSJ PCM unless you can adapt it to the SC by-pass valve signal right?
Did you have to replace the coolant cross over pipe on the LSJ or where you able to clock it to allow enough clearance for the turbo?

yes you must get the LNF coolant cross over tube, no way around it, its not even the turbo that won't clear it, its the manifold itself that hits. the LNF manifold is significantly bigger than the saab one.
