Ignition Timing Tips Hy Guys. I'm Tim from Germany. I swapped a Chevrolet LS1 in my BMW E30 Drift Car. Here's my Setup:
Engine LS1
MSD Atomic LS EFI Kit
LS2 Intake
92mm Fueltech Throttle Body
Injectors: 12569113
Coils: 12558948
MAP Sensor: 12614970
95 Octane Fuel
Cam (LS9 Specs): Intake Duration 211°, Exhaust Duration 230, Valve Lift 0.562" int/0.562" exh, Lobe Separation 122.5°
What would you say? It’s a Stock, Mild or Performance cam?
Which Ignition Timing do you can recommend with this cam? In the EFI Kit I can set ignition timing at idle, part throttle and wot.
I hope you can help me.

That cam is better suited for a 6.2L supercharged engine. It is a stock LS9 cam that makes less power than the stock LS1 cam until about 5000RPM. The wide LSA is what's killing power.
Also, the LS2 intake is not optimum for that engine. An LS6 would do better.
