Description

Features

• Simple plug and play figures
• No forumulas

• Covers all cars of all litres and cyclinders

How to use-

You first use the right hand side laballed as 1.

You enter the max torque output either via a scantool/dyno

you also enter the IQ (injected quantity) max that was used the achieve the maximum torque outout.

This will calculate how much mg/stroke per newton metre you car produces.

You then enter the desired torque you would like your tune to acheive, this will calculate a new IQ figure.

you then copy this figure over to the left hand side laballed as 1.

you also enter the AFR you would like the car to achieve, the cars engine displacement e.g 2.0 and the number of cylinders.

this will then generate the correct amount of boost to cleanly burn the higher amount of fuel and create the amount of air in mgs it will burn(this values needs to be replaced in your lambda calculation maps).
