Car won't take timing with out knock

Other thing I can think off is problem with CAS. Happened to a customer on this form few years ago.

i dont know exactly how a CAS works so from a bit of searching around, most cas issues mean the car wont start at all.

if i were to buy a second hand cas and swap that in, the only way to rule it out would be to chuck it back on the dyno am i correct?

i am keeping the CAS high on the list as many have mentioned it, although when i asked my tuner about it being a possibility he said it COULD be the issue although unlikely as he said "there was no trigger miscounted"  and "the consistency of the issue across the entire map under load"

To rule out a cas issue.. load up the car say at 4k rpm on the dyno and make sure all the cells around that are the same and using a timing gun to see if the timing is synced.

Easiest way to rule out if the cas is playing silly buggers

Yep thought so. Thanks
Another thing that just pictured to me.
I installed split fires before going back to the dyno and I just installed them and started driving it. Was I meant to change any settings in the ecu?
I've seen stuff about split fire "charge times"? Is it like injectors and how they need to be set up correctly first

Nuh.  Plugs and plays.
