Converting a Throttle Position (TPS) to MAP readings can be confusing.

It not an exact conversion simply because you can give a bike a relatively small amount of throttle and create a high kPa reading by forcing a high load situation. But for normal riding situations, the following "rule of thumb" can be applied:

TPS vs MAP

Throttle Position MAP- (Manifold Absolute Pressure)

• 0-6% 10-50 kPa
• 12% 40-55 kPa
• 25% 55-90 kPa
• 50% 90-100 kPa
• 50-100% 90 and higher kPa
