With a E6K is there a way to test the pwm
 

Well I have 2 of the pwm hooked up to two relays to control the sequential but now I cant get my rear turbo come on. I know I can do it like by changing the setting but I want to do this with the car off?

Dunno if you're using it as a pulsing PWM or just an ON / OFF switch, but you need to use an o-scope for the former and a plain DMM can handle the later.

Im using the Dual intake Valve setting toggling on at 4200 and off at 3800.

well I took my DMM and checked the relay I have 12 volts on termal 85, but not sure how to test PWM wire (86). So at 4200 rpm the wire is suppose to become a ground

Yep, PWM's are pull-to-ground.
Easiest way with a DMM is to switch DMM to conductivity with alarm, place one probe to known ground and the other to the PWM wire.
If the PWM "triggers", the DMM should also beep at you.

so i would have to have the car running and lower on point to test it.

Unless the E6K can test trigger the PWM?
I think there's a constant on test setting?
I know the E8 / E11 can do this, but I dunno if the E6K with late version proggie can?
E6X with HalWinX can?

Im not sure when I get back home I will check, Im in vegas at sema. Thanks.

Enjoy the rest of the show...
I was supposed to be there, but a family emergency led me to cancel last minute. :(
Good luck!

Sorry to hear about that. Well I'm hoping to run in to Claudio tomarrow I heard that he is here.

well I finally got a chance to get a look at the wiring come to find out I had the power and ground mixed up 85 and 86, so i fixed that but I still have the same problem I then tested the relay for ground at the 87 and 87A termanls and both pulled grounded so Im not sure what next. I kinda think the Carge Control Solenoid is stuck. but not sure need to geta minivac to test it.

Thanks to Claudio we figured out that this diagram was wrong. To make this work you will need to flip 87 and 87a. So 87a will be the Charge Control Solenoid. and you will have to apply power to the 30 which is common sense, but not for me.

Here is that diagram we came up for the revision to this mod.
