This feature allows the tuner to trim each injector individually for the ultimate performance. This is done by individual Lambda or EGT sensor on the exhaust runner to measure individual air fuel ratios. It is only selected Mercury2 firmware that has this feature.
Trim Count
This is the number of drivers selected by the tuner. The Mercury2 has 8 injector drivers and can work full sequential for 8 cylinders. At can also run duel injectors full sequential for 4 cylinder engines. A setting of zero will disable this feature.
These tuning blocks allow the tuner to adjust the register from 90.0 to 110.0 % for each cylinder. Adjustments can be made in 0.5 % resolutions.
This block is to clear all the registers to 100.0 % to start with. First tune the engine is as good as possible, then do minor changes here to calibrate the injectors. A tip is to use the middle average of the injectors ant tune to that. Example if the injectors differ by 10 % between high and low. Then use the middle vale and some will be 5% high and some 5% low.
