Trigger angle is the angle before/after the trigger at which the coil/injection fires. If the figures are wrong or the setup in the ECU was changed, this means your timing will be way off.

Try checking the timing while it's on power on the dyno.

Hmm ok interesting. Will look into that, cheers. The more ideas the better. I really do hope it is something simple and not the CR as I really don't want to take that head off again.

If we can't sort it out here in Townsville and The Mafia in Mackay can't work it out it's road trip time to a bunch of Brisbane workshops, so you may get a phone call one day :thumbsup:

Forget about CR. It has nothing to do with that

Unless the machinist took off like 0.5mm.....but even then, the head would be pretty f**ked anyway. You can't take off that much material. The only reason that much material would need to be removed is if it had a MASSIVE warp in it, which it wouldn't have had. I cooked my old cylinder head years ago so bad that it MELTED THE COIL PACKS and even that would only have required a 15thou cut to level it

Your problem is located elsewhere

Oh ok awesome. That is very good to hear. Like I said, the CR idea never popped into my head until my tuner said it may be a cause. It started making a bit of sense but I had no idea how much machinist's take off on the head, hence why I started this thread.

    • Mixing things up - installed some leather recaros to match the leather seat covered rear seats. Interior looks pretty schmick now except for some slight wear on the steering wheel which I will monitor and address if it becomes worse or actually noticeable!  
    • Didnt realise RB's had more then 1 head.
    • 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!
