Get 50% OFF your first online course: https://hpcdmy.co/offery115 While the best method to accurately adjust your VE table and/or MAF calibration is to use a wideband AFR meter, a technique many tuners rely on instead is the fuel trims. In this webinar we’ll discuss the pros and cons of both techniques and see how to set up a histogram to capture the data you’ll need. For the webinar lesson we’ll be using the HP Tuners software on a VE Holden fitted with a 6.0 litre LS2. As always though, the vehicle and ECU is just used for demonstration (we have to use something 😉 ) and the knowledge shared will apply to more than just this specific combination. Due to the current global situation we though over the next few weeks we'd help keep you guys out there entertained and release some of these Gold Membership webinars to you for FREE to help pass the time.
