I have gotten my Spitfire 1300 tuned pretty well. It is tuned a little rich but it is best to be a little rich vs lean. Attached are my ignition advance and VE tables. I used Lambda vs. AFR for the air/fuel ratio and have included that table as well. Lambda is fuel independent so using 10% ethanol with a stoichiometric ratio of 14.1 vs. pure gasoline, 14.7, will not impact this table. I've also included my current tune file. The car runs well in all conditions, doesn't bog down at lower RPM and high load nor run out of power up to full RPM.


I've got some more tuning to do to lean it out a bit and will be engaging both the AutoTune and Adaptive Idle features to fine tune the performance and fuel economy.


Thank you for all your help. Without your guidance I'm not sure I would have gotten this completed so quickly.
