Yes, with a Titan 3.2 kg flywheel, the lightweight 950 kg car, and your planned ignition timing strategies on the EMU Black ECU, you have a very strong chance of achieving both a smooth idle at 970 rpm and a well-behaved street car.
Analysis of Your Strategy
Your approach directly addresses the primary challenges associated with a very lightweight flywheel: idle stability and off-throttle jerkiness.
*1. Advancing Idle Ignition Timing (10° to 16°)*
Benefit: The advanced timing (closer to the point of peak cylinder pressure development) will make the combustion process more efficient and powerful at idle speed. This provides a more consistent "push" for the engine's power strokes.
*Result:* This added stability helps overcome the lack of rotational inertia that the lightweight flywheel would otherwise cause. The engine will "fire" more strongly, helping it maintain a steady rpm, which is crucial for a smooth 970 rpm idle.
*2. Retarding Tip-In Ignition Timing (16° to 7°)*
*Benefit:* Retarding the timing on initial throttle application reduces the initial, sharp torque output (torque "spike"). This effectively "softens" the engine's response when you first press the accelerator pedal.
*Result:* This directly counteracts the "overly sensitive throttle behavior" you anticipate. It smooths the transition from idle to acceleration, making pulling away from a standstill much less jerky and easier to manage in traffic.
*3. Car/Flywheel Weight Combination*
*Benefit:* The car's extremely low weight (950 kg) means the engine doesn't have to overcome much resistance to get the vehicle moving. A heavier car would struggle more with a 3.2 kg flywheel.
*Result:* This low mass works in your favor, reducing the demands on the engine at low speeds and making it less likely to stall compared to a heavier vehicle with the same flywheel.
