On the cheap use bike throttle bodies and megasquirt and get a manifold from bogg bros.
As an aside, if you have thousands of pounds worth of engine why are scrimping on the most important part of the engine.
I've replied to this in the other thread. However, fuel and spark are two completely different things.
Timing and spark duration times can adjusted across the RPM range. Additionally, timing advance will be calculated for a variety of inputs including increasing RPM vs. decreasing RPM (braking, coasting, or accelerating), throttle position, temperature, altitude, etc. The ECU is still controlling sparks therefore the timing.
