Car starts and die
 

I just finished my setup with a chipped ecu but my car starts then die, i gap my sparkplugs at .28 to .30 but i dont know what its happening.

I get a bin for my setup at 12psi, but right now i only run 8psi. The sparkplugs are stock and smoked.

What can i do?

My setup:
Stock Z6
T3 A/R .60
8psi
DSM 450s
DSM intercooler
Stock fuel pump
Chipped ecu with uberdata
Open downpipe
Attachment 31985
Attachment 31986

make your own bin for ur setup.

A friend says its a boost leak.

Any other opinion?

Re: Car starts and die
 

.. More info
How long does it run,
whilst its running, if you hold the gas down.. does it stay alive.

You checked all the dizzy TPS , manifold wiring ?

Re: Car starts and die
 

i dont think so...cuz boost leak has nothing do to with that..

are your car recieving spark correctly? check all plugs of your intake ..

Hey Walter it was a boost leak, i already solve that problem and the car runs.

Now i have 2 problems, the first are i have boost spikes, the boost gauge jumps to almost 20psi and my wastegate are set at 8psi, i connect the wastegate to the intake manifold. The second are my car bogs, im thinking about spark plugs but i gapped it at .028, maybe i need one step colder or i still have some boost leak.

Any help?

well if your getting boost spikes check your vacuum line to the wastegate actuator. for the usaul mistakes a bunch of stuff t'd off of the same line, or just a leak.
It could be a bad manifold design to if you have an external wastegate. like the rvhard manifold were the wastegate is on just one of the runners.

Re: Car starts and die
 

Yes i have the boost gauge, wastegate and blow off connected into the same line in the intake manifold

Re: Car starts and die
 

really? mmm then i dont understand why boost has to do with start the car if when you start yuor car there isnt boost.. just when you start your car is almost if your car is NA cuz there 's vaccum still... correct to me if im wrong

about your problem sound like your WG is not receiving proper boost for to open its springs..

Re: Car starts and die
 

Ok, wasnt the wastegate, was the boost gauge. I put a boost gauge from a friend and it read solid 8psi :y.

Now the only problem left are that in first gear the car bogs untill boost, when boost hits the problem gone, that occur only in 1st gear, and i cant rev to more than 3k in any other gear the car pulls ok.
