Discussion and questions related to the course Boost Control
Hi everyone i have a ford ranger 2018 3.2 Diesle engine with facotry ecu....I'm using hp tuner software to tune ecu....just wanted to see if there is a way to change the vnt turbo to a waste gatedd turbo and control boost at certain rpms ?
Vnt controlz boost by exhaust fins done via ELECTRICAL motor solenoid = ( No boost solenoid to bleed air off waste gate because vnt do not have a waste gate )
Waste turbos not going to explain how they control boost its pritty straight forward.
How are people adding waste gate turbos to oem ecus that dont have a boost solined to bleed off boost and control boost via waste gate? Are people just using waste gate pressure and letting the oem ecu add and remove fuel seen thru the map sensors table ?
I was thinking maybe there might be a way to convert vnt 5 wire electric solined to control a 3 wire boost solenoid to bleed off boost....i would imagine boost table would be very difficult to control because its not scaled in with the correct volts but is it possible?
Bump....I'm starting to think people don't care for controlling boost on oem diesel ecu's they just run waste gate spring pressure?
Most instances people retain a VNT turbo, unless it's a heavily modified application.
I would greatly doubt that there would be many people around that would have the required access and ability to repurpose the H bridge that controls the motor, and also clear out the need for the position feedback.
If you are lucky, someone may be able to assist to code out the VNT system (or you may need to leave the actuator assembly in place not attached to anything so it thinks it is still functional) and use an external boost controller (such a GFB D Force boost controller, or Turbosmart E-Boost)
Thanks N8B for the reply.... yeah i get ya....but i know a lot of diesel shops who use Gated turbos and Ditch the VNT or VGT turbos and still use the factory ECU.... thanks for telling me about GFB force boost controller and Turbosmart E boost options. this is probably what other Diesel shops are using to control boost.
