I would like to see one on custom formulas. I asked for one for new ve on one of your videos. You kindly gave me one with quick reply, but damn formula wont go through. It all looks right. Everything exactly spelled correctly like it is in data drop down. Very,very aggregating. Using PV for logging. Made a formula for desired afr by lambda × 14.7 and that formula worked. Then (VE Front)×(AFR)/(Desired AFR). But with brackets. Whats wrong with that formula?
