Default TTS Master tune


I have read a few threads on the TTS Master tune and it looks like one of the big selling points toi it is the ability top suggest settings for you VE tables as well as the FBW status. I am curious as to how usserf friendly the software is for the average person to do a little work at home if they have a basic map for their bike. The other question is if you make a few changes like increasing compression or adding heads woiuld the TTS be useful instead of having to get it redynoed?

Just finished TTS training here at Latus and we are now a dealer for that product. It is the pre-Pro Tuner version of SERT and is by the same people who made SERT. But it has several new features that SERT/SEST does not. How "user friendly" the software is depends on your experiance with SERT. New users to SERT have traditionaly found the learning curve fairly steep.

The TTS does NOT eleminate the need for dyno tuning. In fact a dyno is required for non-closed loop cells, WOT and "learned" cell tuning. An owner can, however with diligence, record "learned" cell VE values and generate new VE tables based on these, in the closed loop active areas. They will not be as accurate as those done on a dyno as they are transitional vs steady state. But this wil not address WOT fuel, timing and open loop functions. Timing could be tuned via data record by looking at knock control but this will not give a complete picture, especially on high compression motors.

Head or compression changes are massive to air flow and the closed loop system may not have the ability to account for these. Other tables may also require adjustments, that are done manually, with these changes.
