Message: [QUOTE="907DAVE, post: 355374, member: 672"] The next map is MFD. [ATTACH=full]88333[/ATTACH] This map is what the PCM uses to determine how much fuel needs to be injected, along with a few other things. We will focus on the fueling side of things. Vertical is a number rated in Mg per Stroke, lower left is APP rated in A/D counts (computers way of seeing voltage), and lower right is RPM's. The next step in determining what to do starts with the ICP map. [ATTACH=full]88334[/ATTACH] This map takes the previously determined MFD (bottom right) and RPM (bottom left) to calculate what ICP (vertical) should be. From there we go over to the PW map. [ATTACH=full]88335[/ATTACH] Bottom left is ICP (in Mpa), bottom right is MFD, vertical is PW. Now lets put this all together with an example. Cruising down the highway with the converter locked in at 2000 RPM's. We'll say the MFD map is asking for 15mg/stroke. Jump over to the ICP map with those numbers and it says ICP should be 1160 psi. Now we can take those two numbers to figure what PW should be. 15mg/stroke at 1160 psi (9.65mpa) will net us about 1.1ms PW. Now lets roll into the throttle a bit to pass a Honda. RPM's stay the same, but MFD jumps to 53 mg/st. Bring that to the ICP and it wants 2400 psi (16.5mpa). Plug that into your PW map and we get 1.7ms PW. Neat stuff, eh? [/QUOTE]
