how acurate is the hsw interface? im wiring mine up rite now and i just wanted to see how accurate it is in the fuel enrichment. i have it set for a 125 shot but should i set it for a little but higher of a shot so it gets enough fuel or do you think its fine? thanks for the help
thats a good point. The interface assumes your NA A/F ratio is on target and adds fuel from there to get to approximatley 10.8:1. Every car out there is different so it may not be exactly dead on with the HP levels indicated. Thats why we call it an A/F adjustor, so if you are lean or rich you can either add some fuel or pull some out. Obviously you want to get the car on a dyno and adjust the interface to get the optimal A/F ratio you are looking for. They are made on the conservative side for when they are first dropped in. The best A/F ratio is around 11.5-11.8 so just adjust the interface to get there.
