HFS-3 Question

[Richard L]

This is true and a good point. If your injectors do max out at 100% DC, you should not use the gain trimmer. If you want more flow just putting more jets.

This gain trimmer was intended for those who uses very large injector intended for E85 and when E85 is not available they use the H3 to suppliment of the pump fuel map (not maxed).
