1KD-FTV - Electronic BOV Controller Connections

Hey Guys,

Looking at doing Oz Bush's EGR Full blank but am concerned for the Turbo backpressure aspect that the EGR doubles as. With a Full block this will no longer reduce the pressure on the turbo.

found a few Diesel electronic BOV Controllers that basically add a electronic solenoid that is then wired to the controller and the controller gets a signal from the TPS when you back off to open the solenoid and allow vacuum to open the BOV as it would in a petrol engine then close it again when you accelerate again.

Wondering where i would get the TPS Signal from weather it be off the pedal or the TB before the EGR? Keen to hear from anyone who has run this kind of setup have heard a few hilux's with BOV's I will be installing a plumb back BOV purely for its job not for a whoosh hahah

After reading the above link, The ECU has a Pressure relief valve output, which powers a solenoid to send vacuum to the 2nd side of the EGR to open it to release pressure from the manifold as required (exactly like a BOV) so in theory using that vac line to a newly mounted BOV after doing a full blank of the EGR will activate the BOV as required and release the pressure that the EGR used to before it was blocked.

am i on the right path?

After some more reading its not as mentioned above, Got a bit excited Pressure relief valve is on the commonrail for fuel.

Not sure on how the EGR is told to dump pressure and which part of the egr controller does it.
