What Would My Compression Ratio Be?

[PM-R33]

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

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.
