Means the air/fuel mixture inside the cylinder is exploding under its own free will from compression instead of burning when the engine ignites a spark from the spark plug.

Ie. your engine will eventually die if it continues like this.

thanks mate, so the fix is a tune. could it be because it was not tuned properly when i put in the Power FC a couple of months ago.

is the problem only happening when the light comes on during high boost or all the time?

Yep a tune will fix it. Did it get tuned when you installed it? Or are you just running it on the base map?

The light also flashes if the injectors are maxing out, or if the airflow metre is maxing out. So it could also be that.

Check your hand controller's max knock count, max airflow voltage and max injector duty cycle to see what one it is. But most likely it is knock.

Best bet just take it back to your tuner and get him to check it out. When you take it there, get the car's engine light to come on along the way but don't turn the car off when you get to him. That way he can have a look at all the max values on the hand controller and tell you straight away what's causing it. Whether its knock, the afm or injectors.

Good luck.

i started reading and when u didnt know wat knock was straight away i suspected u wouldnt have the correct fuel in it... i see it alot.... kinda makes me angry sumtimes lol..... if it was tuned on 98 and ur gonna go flog it sumwhere make sure it has that octane fuel in it. minimum u can run lower octane fuel if ur just lightly cruising but it still not recommended. my 2cents

yeh i no it was tuned on 98 and i'm ment to run 98, but the servo had run out. they only had 95 and i had 10 mintues to get to the crusie. what i didn't realise is the damage that could of been done while i was out with 300 other cars letting her have it for 4 hours.

well shouldnt it have clicked wen for sum reason sumthing different is happening now that ur not running the same petty(generally flashing lights mean get off the go peddle).... like seriously now. thats like puttin canola oil in ur sump and saying oh she'll love it..... sorry to rant on but sum ppl are just so ignorent.

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
