can a miss fire / back fire trigger safety boost or will only detonation do this

Well an internal misfire can mean dett. These cars suffer from issues on the dett sensor and harness that cause false alarms anyways.

I herd a pop/bang then went to safety boost just wondering if miss fired and that triggerd the safety boost

safety boost will be cleared by turning ignition off/on ...

yes its done that just want to no if a back fire could trip safety boost say from over fueling

no, an exhaust pop won't trigger the knock sensor

I just spoke with a tuner he has been going a long time he just said a back fire or misfire can trip the safety boost not just detonation

i dont know much but as i ubderstand it but i could be wrong. detonation is when you have unburnt fuel left in the combustion chamber for what ever reason then when the next cycle of stoke/combustion takes place the unburn fuel egnights before the norm clyle takes place millisecound before. so if you amagine you have two explotions in a container/area when your only ment to have one bang. but now you have two one after the other, out of the timming cycle and the bang or explosion if you like collides with the norm explosion and clash in the same space ,the top of the piston the combution chamber. this collisin of explostion if you like is called dett or detonation. and can be caused buy many issuses. and if you have it will cause if working correctly the knock sensor should pick it up and if left to carry on could if to lean melt a piston or do some serious damage anyway to your engine. weather you get a secounary bang in the exhaust system is as first thought ,well if something making loud bang then something surely burning out of sinck i would have thought.

sorry for my crap spelling. hope this helps.

well what ever the pop/bang was it sent the car in to safety mode

The knock sensor on the zed is just a microphone on the block, no where near the exhaust.

and to add, it only really works up to about 3500rpm, at which point there's too much mechanical noise and the ecu ignores it

Never knew that, it's a damn chocolate teapot then! Your high end is the most dangerous part of the curve.

yes it was under 4k when it pop and the safety kicked in

what have you changed lately? or have you done something else, chaned you plugs ect

Download yourself a spell checker mate. Google toolbar app comes with one. :)

had a new cam belt fitted by z world and that's it I wounder if the timings is wrong
