Volumetric Efficiency (VE) fuel models are becoming more popular in aftermarket engine management systems. For those tuners coming from a traditional ‘injection time’ tuning background it can be easy to overlook some important aspects when tuning a VE based ECU. In this webinar we will look at the differences between an injection time and VE based fuel model, and how to approach tuning.

For this webinar we will be using a Haltech Elite 2500 ECU fitted to our Nissan 350Z.
