im looking for insight on the functions of most of the cars sensors...some questions are even as rediculous as this" with a ported TB and upper lower inconjunction with the fact i have a stroker,might i be showing readings on the map above its normal operating parameters(i.e. slight boost) and would a voltage clamp help me if so? if maybe how could i check? by passing the knock sensor and or clamping it and or a filter ,might i get some advance from that? i understand its harmonic? why when i ice my upper intake at the track does the car run at minimum .1 faster ? its consistant and repeatable...i would think icing the upper causing the IAT to see colder air would have it add more fuel? but does it also add timing ? maybe the timing is better than the running rich power wise? you know if we could make the emanage ultimate work for us NA guys this would prolly answer all my questions?
