The M9 (don't think the M8 is the same) has a kidney bean shape combustion chamber. The ones prior have a hemi shape. If you have a M9 head, that would explain the pinging since the compression would be higher than normal. You'd have to change to an earlier head with a hemi shape, or use higher octane petrol.
BTW I too am using the TR manual ecu.. The TS man ecu is a different part no.
They should both be pretty similar.
I thought the ecu retarded the timing when it hears detonation
If the knock sensor is connected.

Mine has run lean if I have <15L in the tank, turn a corner and the fuel pressure drops. For me, this doesn't cause pinging, but the engine just struggles, and you can feel it lose power.

It would more than likely make the car run really rich, and blow smoke.

Going up hill could be making the fuel slosh away from the pickup, but would cause lack of power, not actual pinging.

Yeah, it should be 5 degrees BTDC (Before Top Dead Centre). Then when the ECU controls it, you should see it hovering around 13 degrees BTDC.
