Engine Detonation :-(

[WRXONP]

3 kms difference? i dont understand the way u word things lol

if its detting in high revs - it sounds like its leaning out

clean afm - check plugs (heat range) - spark blow out (large gap) wont cause detonation - it will cause a miss fire

leads / coils wont cause detonation - they will cause misfire

detonation can be from lean mixtures - or timing too far advanced - or hot intake charge - theres alot of things

evowrx: Is yours nz new model with the upgrades (no speed limiter, 260k speedo, orange airflow, yellow injectors and 4 pot front calipers).

They run 1 bar factory. A standard JDM v5 non STI runs 11-12 as they don't have the supporting mods.

[Guest]

mines import too. yellow injectors 180kmh speedo with cut, 2 pot brakes. think td04 internal pressure was 12psi. my forester was exactly the same with yellows speed cut 180kmh. both phase 2. the forester was 12psi standard.

think you confuzzled - ver 5-6 run insert maf - no orange maf

[Guest]

as above all v5/6 sti and non sti run the same afm. theres a difference in sti vs non sti ecu/boost levels afaik.

[Kiwi_Fozze]

v5/6 wrx runs about 10psi with a 14.7psi cut (1 bar)

v5/6 sti runs at about 14-16psi iirc

Its been covered multiple times on here.

Nz new are different and do use an orange maf.

Use the search function.

The upgrades stated are factory options that were available on nz models.

[WRXONP]

Wrx_lou maybe u should use search function ??? Lol

Phase 2 don't have a coloured maf at all - they run a insert type

exactly same afm by my research even by genuine part number.

i think he just needs a link/engine management so he can tune it sooner or later you will need to. will get more out of the car and better gas bill too. my set up is far from standard now and seems to run fine no det that i can hear. hell rich though but all about to change.

Actually its quite relevant as in this case it can be many different factors buddy

[joshhorn16]

Yuss, new coils and leads. she goes like the wind now noooooo problems at all ;D

[Guest]

did you try replacing them leads then coil or vice versa to work out which it was?

[Pappu1]

good to see it running

[madmike]

So new coils and leads and it's running good...

So what you had was not det.. You had a missfire.

didnt gary capper tell him was det....?

he would know the difference between misfire vs det.... well most decent ppl wud lol

but seriously tho, big difference between the 2 (maintanance issue vs OMG engine will die at any moment of boost)

[madmike]

You would think so a.....

Aparantly in the thread gary told him he was using headphones.. So i'm assuming he had a knock sendsor on it and heard what he thought was det..

Not sure how he heard that when it was a missfire but hey...

I stand by my original statement...

[joshhorn16]

Yeah gary said it was det which confused me cause i thought it was misfire to begin with guess he was wrong but oh well i will go have a chat with him this arvo and see wats up

[WRXONP]

i highly doubt the coil was at fault

more than likely a lead - but anywho

a miss is far from detonation - det is like a hammer hitting the piston - a miss fire will just lack power and produce black smoke

[joshhorn16]

funny you say that cause heaps of people have been telling me that there has been black smoke out my exhaust as i scream past them i will get someone to confirm this has gone tomorrow

[WRXONP]

it will only produce black smoke when it miss fires -

a turbo car should black smoke on WOT (IMO) as black smoke will come from the exhaust at around 12.5:1 and under AFR

IMO a turbo car that doesnt black smoke is too lean - but alot of black smoke is too rich (robbing power)

scare tactics perhaps hahahah

i have heard that cheap wof places do that to scare ppl into getting things replaced at their workshops as a possible wof fail.. similar sorta trend maybe..altho i dont really think it should be the case...
