Simon Posted August 26, 2010 Report Share Posted August 26, 2010 Moving the master will be a good start. You will still have to check the mixtures through the full operating range. Making adjustments as needed to the zone or row fuel. Quote Link to comment Share on other sites More sharing options...
Brett Whinnen Posted August 31, 2010 Report Share Posted August 31, 2010 You can roughly calculate the value to change the master to given the ratio difference of you old to new injectors. This will get you _pretty_ close. But you will have to always then modify zones to suit. I did this moving from a set of 440cc to 700cc injectors with minimal re-tuning required.
