tried everyhting in the thread..even put a new different ecu on to check that...

welcome to owning a nissan skyline lol get yaself a wasted spark set up or splitfires m8 ive got a 32 and 33 and both seem to miss fire like hell under high revs, or maybe even try chaging plugs as daft as it sounds, if they are breaking down or blowing the spark out when your coming on to boost.

cheers for all the help guys...
iv owned skylines for 3 years now and never encounterd this...
iv rule out the things on the list..just wating for delivery of my wasted spark kit..as i reckon it could be the Ign Amp....only thing left tbh...
also i should check the timingbut i doublt thats the problem tbh

If you suspect the ignition amp them surely the wasted spark kit is going to be of no use as it still needs it to run?

Cypher · 28-06-2008, 11:01

yeah but i have a new amp coming aswell and i recon the WSK will help stop the problem happening again

Cypher · 02-07-2008, 22:40

right..its still doing it..
iv done everything i can thank of...got the wasted spark kit, new sparks, all ignition system is fine.im sure its nothing like that....

now here is my new dilema...
if i run the boost standard, by running the actuator off the intercooler pipes it boosts to 0.4/0.5 bar then stops..but it wont go above about 4500rpm in any gear...no missfire thou

if i run the boost controller at any boost pressure (as low as .4 bar) the car boost spikes to about 1/1.2 bar then missfires (i assume this is fuel cut by the ecu)

so any more ideas..
im thinking of changing the fuel filter tomorro as i havent done that..hopeing this will help...

im runing out of ideas and ime..gotta get it working properly for tuesday as i leave for nurburgring

Cypher · 05-07-2008, 19:51

right..got it working..

all i did was fit a wasted spark kit, fmic, new oil and plugs...that was good..ran smoother....
but still wasnt boosting properly or revving all the way up...
so i changed the fuel filter..and it works fine, boosts all the way, holds at .8 bar..running sweet..
so there you go. change the filter..

wish I had done this 1st! then prob would but new clutch in it and skidided it every event possible!

You got a great motor & deal there!

after all the replacing of parts, uprating to FMIC, wasted spark kit, plugs, coil packs etc.......it turned out to be a simple thing that one of us should of thought to try first. It's so simple its just silly! The bloody fuel filter was blocked a bit! Cyper fitted a new one and all is fine and the car pulls like a train all the way to 160 MPH.

Wish haddn't sold it now, oh well!
