Guest suprageek Posted October 20, 2013 Share Posted October 20, 2013 so I have a blitz sbc I'd 3 boost controller and power meter, when I'm on boost at about 1.09 bar the car cuts for a second or so and the engine management light comes on then goes off again, however if I switch off the boost controller the car pulls fine and reads about .89 bar and no cutting out, hasthe boost controller had it or is it something else boost related?

Scott Posted October 20, 2013 Share Posted October 20, 2013 Sounds like fuel cut. Quote Link to comment Share on other sites More sharing options...
Guest suprageek Posted October 20, 2013 Share Posted October 20, 2013 Feels like it too tbh what would cause it? the controller has been in the car ages and I've never had an issue until now. Quote Link to comment Share on other sites More sharing options...

Not having a fuel cut defender would be the issue. Colder temps would increase boost spikes leading to it boosting over 1.0bar which is where fuel cut is triggered. Easy way to solve is to re-adjust the boost back to 1.0 or to fit an FCD. Quote Link to comment Share on other sites More sharing options...
Guest suprageek Posted October 20, 2013 Share Posted October 20, 2013 Ok just had a look there is a greddy boost limiter cut controller in the car, is this a fuel cut defender? Quote Link to comment Share on other sites More sharing options...
Scott Posted October 20, 2013 Share Posted October 20, 2013 Ok just had a look there is a greddy boost limiter cut controller in the car, is this a fuel cut defender? Yeah that's the chap. Maybe it needs adjusted or something? If that's in and it was working, something has changed. I'd recommend you take it somewhere for a look.

Guest suprageek Posted October 20, 2013 Share Posted October 20, 2013 I've just had the car back as the star wheel came of the crank timing pulley so the car has been sat for a week with the battery disconnected, would this of had an effect on it? I see there is a little screw for adjusting it inside the controller Quote Link to comment Share on other sites More sharing options...
Guest suprageek Posted October 20, 2013 Share Posted October 20, 2013 Bit strange, the green and the white wire are not connected to anything! How did this ever work? As the car had run fine set to 1.2 bar until now, The green wire was taped off at the end and the white is just hanging there, Quote Link to comment Share on other sites More sharing options...
