It was giving me issues with misfires under load, ignition module, cam sensor and crank sensor fault codes. Replaced them all and still the same until I did the new earth's hahaha. Costly fix for $10 worth of wire haha
Maybe check your earth's on the coil pack. I was having trouble with mine when I moved them off the engine to the side with shit bracket. Had to put some earth's from coils back to the engine. All sorted. Might not be your issue but worth a shot.
Where is the Haltech getting the voltage reading from? Looking at your data your voltage drops from 14 to low 12's and then continues to drop, to me this looks like the alternator has stopped charging and you are only running off battery voltage at that point. So either there is a issue with the alternator exciter circuit or how that circuit is controlled. Could a safety setting in the Haltech cause this? The engine block is the main ground reference point, your battery to chassis ground needs to be the same size as the power feed wire and matching ground cable from the block to the chassis.
Hey mate id dump that rear muffler if it's the redback style 2 in 2 out as they are extremely restrictive and the more pressure you try and push through them the worse they are. It's an easy job to see if it's that
When you started your car, it sounds like there’s a lot of lag and it doesn’t have that powerful start sound. I’d be upgrading your battery cables while you’re there.

Good luck man

Dedicated grounds now. Seems to be from another issue

reads off a 8amp pd16 channel. have just moved to fuesbox side and same reading so its time to point towards the charging system..

New zorst plan in the works

Yeah we added a 2nd earth it fixed the starter issue. Just not the haltech one
Good luck mate, haha always wanted to say that
Cheers mate.
Do you need to fix your hood lining in the Commodore?
One day, got Gremlins to kill first....
how thick is your battery pos wire? i use to have issues on dragcar had to run a big one used earth strap wire off a welder cheaper and thick
2 B&S its defiantly got the gauge.. so now to look deeper..
spark plug leads?
Na not ignition related
Besides the saggy roof lining causing the voltage issue, is it possible that you’re spinning the alternator too fast?
Not getting anywhere near Max rpm. It's the same crank and alternator pulley dimensions so it's not like its overspinning
