My car has all of a sudden started running on safety boost! Was fine for about 100 miles up M6, then last 50 miles, started playing up! Any idea's what it could be? I've checked oil, water etc, they're all fine!

have you done an ecu check

Det sensor?

What does the det sensor look like? Its fine for about 10 minutes after i start it up, then seems to go wrong again!

You can't see the det sensor, its right down back of the block.

 

Do the ECU test while the car in in safety mode without switching ignition off (it resets it)

My car has also started misfiring very slightly!

Missfire is probably a dodgy coil pack / plug or loose connection, although it could be other things check the connectors on top first.

 

Missfire could lead to rich mixture in whichever cylinder it occurs in, could lead to detonation I guess and then safety boost.

My car is running rich, is this a serious problem? It only seems to lose its boost when its warmed up!

High combustion temperatures and running rich will cause detonation. Although I'm not sure how good the det sensor is on the Z at being accurate. Best ask one of the pros. Have you noticed any pinking on WOT under load?

 

What boost / chip are you running?

1mm boost jets and a mines ecu! Fitted at ztech last week! it was fine for a few days, then started 'clicking' at full boost! Now this!

If it is making a noise like pinking under full throttle / load, sounds like detonation to me, best get it back there and looked at, last thing you want is (worst case) to blow your piston rings apart. Could be a false alarm, i've not been in it, heard it or looked at it, but it sounds like the problem to me.

 

What Ron petrol are you running with it?

97RON with octane booster!

K fella not much more I can say on it really.

Ok, problem just got a whole lot more serious, its now misfiring like buggery and is even cutting out on me! Boost seems to be ok now, but it does det at high boost! What wrong with my car? If its serious, i'm gonna torch it!

Give ryan a call fella and get him to take a look at it.

 

Cheers.

Can't get it down there, there's masses of oil in the pipes where the boost jets go on the left! Turbo gone? Hoping its just a pipe!
