I have the new "Tuneboy" program (I think) that has a red screen and compatible with the Roadster. I have already downloaded numerous tunes and it works great. I was wondering about the three tunes that can be stored in the ECU. I'm not sure what tabs are for the different tunes. Across the top of my Tune Edit screen is the following;
F1, F2, F3, Fuel % Trim, L1, L2, L3, I1, I2, I3, I4, I1_1, I1_2, I1_3, I1_4, Ignition Trim, Sec, AF, F_L Switch, Idle Speed.
I always thought F1,2,3 and L1,2,3 were for the different cylinders. Are these the tables for separate tunes, changeable with the clutch? Also, what are the "I1_1,_2,_3,_4" tables for? Any help would be greatly appreciated.
