Re: 5kt Boost Problems (too much at the moment)
Sorry to interupt this fascinating discussion on spiders named Boris,
and whether or not Dave Eaton will have enough time to get married.
But any pointers on finding out why my wastegate frequency valve won't
work would be most welcome.
I ran through both the input and output tests for the MAC-11, all
tests check out fine and the wastegate frequency valve clicks and the
LED (I hooked up) flickers off and on. I then tried the multi-function
switch test which involves runnning the engine at idle, unplugging the
WOT switch connector and shorting a couple of the pins together. At
this point the freq valve LED should flicker, it didn't, so I replaced
the multi-function switch and repeated.... still nothing, hmmmm Orin
mentioned these switches can be DOA - any way to verify?
I guess I'm looking for some pointers why this test wouldn't work?
There could be a break in the wiring from the multi-function switch
connector but I'm not exactly sure where I measure continuity between
(yeah obviously one point is on the connector:)?
I would also like to probe out the connector at the ECU. As I
understand the multi-function switch sends a cold and too hot signal
to the ECU, where and how do I measure these signals. I was planning
on running the car and measuring the signals at the back of the
connector at the ECU?
The car is running fine with the wasteg gate open loop, except when
you hit the over boost shut down... this has happened a couple of
times at the most in opportune moments. I'm developing bruising on my
left shoulder from the seat belt.
Thanks and regards, Mike
