Coil pack problems on my r33

[Zahos]

not at 10 - 11psi (0.7 - 0.8 bar)

can you check your timing?

When does it happen? the entire rev range, or only at a certain point?

Have you guys got a boost cut defender or aftermarket ecu? as the stock ecu will cut ignition at about 12psi.

Just a thought, it might be boost cut.

I am running NGK BCPR6ES (pre gapped at 0.8mm) with 200 odd rwkw and I can just keep winding the boost up (most I have used is 1 bar - its a stock turbo) but haven't had a problem.

Heres how i would go about it.

1 set boost to 11psi or lower if the problem exists at that boost

2 Have my new plugs gapped to .6 or so

3 Take kick panel off to expose the computer and check wiring for loose connections

4 Unclip Ignighter pack for a known good one and take the car for a run

5 Take 1 known good coil pack and give it a run each time swapping good coil pack to a different cylinder

6 Replace computer with known good one

Ive done this from easiest to hardest labour wise..

Ecept the computer as it is rare for it to happen plus availability of a spare is sometimes difficult.

Good luck mate

When I set the boost more than 0.7bar. I will have the poping sound/misfire. And this only start happen at around 4500rpm to 5000 rpm. After 5000rpm or before ~4500rpm, it runs well, even with 0.85bar boost.

Any chance that your boost guage is reading lower than it should be ?? I've heard of this happening before....

Nop, its running 10psi and it feels like 10psi doesnt really give you that kick back that 13-14 would start to

OK....Gave the car I run today....running at .8 BAR the car started misfiring at aroung 5000RPM...

I had a look at the S-AFC and noticed that all the settings were set to zero. I re-entered the correct settings but unfortunitly the misfiring still occured but now it starts to misfire at lower revs...

i had this problem with my 33........turned out to be standard fuel regulator. i got a malpassi and everythings sweet........to test coils pull em out and take to auto electrician...they should have an ohms reader to test the resistance......
