EVERYONE knows about API

Look in the traders section

 

make sure you still have the little restrictor in the bottom pipe of the boost solenoid

 

i have never had that,, it came with silicone pipes nothing in them ,,,

 

Close your spark plug gaps up a bit say 0.8 mm. Mine had a misfire when i put in a chipped ecu and closing the plugs up sorted it. Dont run more than 1.25 bar.

 

hi thanks i have no miss it stop pops and go,s agin ,,,im going to put the td05 back on and try a better boost gage ,,,see what it boost to ,,cant tell with the cheap one ,,it might be dodge ,,

 

if someone has put silicone aftermarket boost pipes in and not put the restrictorbackin then that will defo cause overboost.
post a pic of your engine bay.

 

boost pipes are blue ,,no restrictor ,,but would it stll do this with my old ecu ,,it runs good on old ecu ,,thranks for trying to work this out for us
just been offerd a walbro from ascoobynet member so going to fit this and a better boost gage ,,then see what happen

 

depends on ecu and difference between boost target and fuel cut. so yes it would be different from ecu to ecu and yes if you aint got the restrictor then that is the cause of the overboost espically since you are using a chip. the boost target will be very close to the fuel cut.

 

thanks a lot i will have to try get a restricto to put in the pipe ,,the boost on the ecu is 1,0bar ,,,,thanks

 

right i hve the boost pipe coming with the pill ,,,all boost pipes are in right place
so if i fit the new bits and it still cuts out can i take the chip out reconnect the j1 resistor and will the standard z4 ecu run the front mount intercooler ,,

 

you don't need to take the chip out you can just reconnect the j1 link and it will run as if the chip isn't there.

 

thanks for you halp ,,,the chip just plugs in to a holder ,,,so will it be safe standerd z4 + f/m and tdo5 ,,,,i have put all the right boost pipes back just wating for the one with pill in it and fitting a walbro 255 pump thanks

 

cool. good luck. let us know.

 

where abouts in bradford are you?

i'd take it to richard henry motorsport in west bowling..

but saying that.. in this thread alone you've taken the turbo off and on so many times.. you handy with the spanner?

take a trip down to them and have a chat, they'll give good advice and you could probs have a go at rectifying it if you can do it yourself.

 

well thanks for all your help ,,,,BUT ,,its stll not right ,,ftted today walbro fuel pump ,,boost pipe with pill,,still boosting way past 1 bar and cutting out ,
so im going back to standerd
its better to use the car [safe] than blow it up ,,i took the chip out of the z4 and re solderd the j1 ,,still the same
so over the week end im going back to standerd and we will have a sale on scoobynet
thanks to you all for trying ,,,
