R32 Missfiring Problem

[ZILR-34]

hey guys

ive got a missfiring problem. its been happening since ive had a tune. and starts at 5000rpm as soon as it goes over 13psi.

i have changed my plugs 4times and different heat ranges now at different gaps 1.0, 0.8 and 0.75mm. and still missfiring. i also got sum Splitfire coilpacks and still missfiring. ive also got a new 040 fuel pump and new Z32 AFM. the only thing i can think of is the CAS. could this be the problem???

my mod's are

K&N pod fillter

3" exhaust turbo back

Plazmaman Plenum

cooler 600x300x73

R33 GCG high-flow turbo

Z32 AFM - in cooler piping

Bosch 040 fuel pump

new GTR injectors

Splitfire Coil Packs

also did a comp test and it was

1 150

2 150

3 138

4 148

5 150

6 150

cheers

bump anyone?

ignitors also cause this issue maybe swap it over with a mates one,. every one has a mate with a skyline these days

timing too advanced?

is it missing or pinging?

Try change your fuel filter, a fuel pump sorta fixed the problem in my old 32 but wasn't until i changed the filter as well that the car was totally smooth

Mine was misfiring above 4000rpm

Turned out to be crank angle sensor, give that a look over

well when it was on the dyno the first run it did 212rwkw's and still lots more to go after that it never hit that again. it was losing power each run. i check the piping like 10times.

ill check the crank angle sensor and the ignitor

cheers
