very easy on a t6,,,, as you can see here,,,, i havent though

It's all about the design of the pistons, bowl shape in the head, etc.
I can't see the merits of 7.x:1 compression and 2+bar of boost myself.

Definately will give it a go at some point.
I suggest you and Stu have your phones turned off that week though

Hope you can individually trim ignition on each cylinder then mate, LOL

Pretty sure my autronic cant either.
but TBH it doesnt really matter to me as i couldnt be arsed to trim them if it did, i bet you have 1.00 in ALL those options
In fact I bet you arent doing anything with your T6 that i couldnt do with a dizzy and a good selection of springs and weights

Individual cyl trim is WELL handy on Skyline GTRs as the std plenumn is wank with regard to equal airflow and fueling is way different from 1-6
What seems like the right mixutre if going by a single probe is almost deffo well rich one end, and dangerously lean the other.

as this topis seams to have the engine people intrestind in
who's used wha for det sensing
pressure sensor installed flush with the combustion chamber
pressure sensor connected to the spark plug
temperature measurement at the cylinder wall
acceleration sensor, frequency tuned
acceleration sensor, not frequency tuned
force measurement at the cylinder head bolt by the use a special washer
deformation measurement at the head of the cylinder head bolt
spark plug with a ring made of piezo ceramics
ionic current measuring method
ive used none of the above

Ive detected det in the following ways:
listening with home made det cans
listening with electronic det cans
scraping bits of piston off the cylinder head chamber
I try to avoid the last one though, its an expensive method of tuning that thankfully i havent done for about 6 years or so now!

big puff of smoke out the back of my car going into quarry.
Limped round the rest of the lap, pulled off.
Decided it was probably the head gasket, and that i could be back out in the afternoon, so i got back to pits and ripped the head off only to look at the gasket and it was fine (literally pulled it straight off the block to look wihtout really seeing anything else)
Im stood there looking at it, holding it up to the light to see where its gone etc, and then i glance over at the block, and ive only got about 3.8 pistons left, and then i look at the underside of the head and find my iron cylinder head is now ally coated
Needless to say, i didnt make it back out that afternoon in the end
