Guardian Angel compatability
Posted: February 23rd, 2017, 2:53 am
ok so I'm replacing my turbo and going bnr s4. but i'm on stock block and its my dd. so the thought of a secondary safety device to prevent the turbo from blowing my pistons to the moon in the event of over boosting. And with stock block this seemed like a no brainer... but i'm thinking the versatuner tunes off load logic. and not by boost psi like ap. so with the ap. if you were running 19 psi and it spiked to anything above 20psi the guardian angel would save you a$$. but with versatuner doesn't that mean that to get to a certain load value. versa might have the turbo spool to 22 or 25 psi but go back down as needed for to hit load value. but with that said doesn't that mean that the guardian angel would have to be set to such a high psi that the car could still over boost? if say it went to 25 psi when it should only be at 17 or 19 in that part of the load tune.(meaning normally it should be a 19psi at that rpm on that tune. but say if a bov or bcs hose disconnected and its overboosting in too low of a rpm. where it could hit that number no problem later in the rpm on that tune). so there for its over boosting but if I set the guardian angle to 19 so it wouldn't let it do that then it also wouldn't allow it too go past that in the later rpm's when its perfectly safe?
I know there is a secondary switch to have a secondary trigger. is there a way to hook up the secondary trigger to versatuner in a way where when versa or the ecu rather detects over boosting and initiates fuel cut that it can also do the secondary trigger for the guardian angel. im gathering everything for my build now and want to know what need to do. so when I get to that point I know what I need to do... thank I appreciate the advice!!
