ECMlink EBC Issues

[TalonSpeed]

My setup:
HX40 in small bep housing. Tial MVS (22lb spring inside )Recirculated O2. I have the Ingersolls 3 port solenoid. I have it hooked up just like the wiki page but I have boost controlled turned off in link. I have it off cause I am dialing the tune in and going easy on the motor. Just did a lot of changes.

My questions is, with the EBC turned off but hooked up, shouldnt it stay in an open state (inactive state)? I was under the impression if something fails, the solenoid stays open allowing the wastegate to function by itself.

What is the default state? active or inactive?

If its not receiving a signl it will function off the wastgate spring.


Only the bottom port is seeing. Pressure.

but just to correct your statement if the solenoid was stuck open the top would continue to see pressure and boost would continue to rise beyond spring pressure.

When i hooked mine up that way and forgot to check the box for boost control it built crazy lots of boost. If you want low boost check the box and leave zero's in the tables and that will run wastegate pressure.

This should not be the case. As described below, the bottom port of the wastegate should receive boost pressure while the top port recieves nothing. This would leave the wastegate to operate off spring pressure since there is no boost pressure acting on the top side.

When inactive or de-energized (unpluged), the bottom port is connected to the common port. So if you unplug the solenoid, the boost should operate off of the spring pressure. The quote and picture below explain in more detail.

The typical installation will involve routing the hoses so that pressure is applied to your wastegate actuator (which opens the wastegate and reduces boost) when the solenoid is deactivated. This provides some safe guard against a solenoid failing in a deactivated state (typical failure state) or becoming electrically disconnected. In either of those failures, you would simply end up with wastegate pressure (typically around 10-15psi) as your resulting boost pressure.

This entire process can be found on ECMTuning here. http://dsmlink.com/wiki/bcsinstall

My suggestion would be to hook the solenoid up and check the box but apply all 0 values to the base duty cycle table. Once you confirm you have control over your boost (a short pull to verify boost) you simply raise the percentage to raise your boost.

YAMAHAULIN is correct. Unchecking the box does cause crazy high boost. I think unplugging the harness would make the valve open and run wastegate pressure. Unchecking the box must keep the ground active therefore closing the valve. checking the box fixed my issue
