[QUOTE="Charles, post: 1566115, member: 103"] I think a pump body to hold the unit pumps together exactly like P&B's on an inline P7100. Hell, the Mack EUP's even have staggered two bolt flanges, just like a barrel. A big ass barrel but that's the meat needed for the pressure. You configure them 4 and 4 in a V with their own cam. Should be similar to 4 HEUI's deep toward the turbo. They should fit ok. Electronics are very likely compatible right from the word go. Turn the key and it fires with the timing and pw you write into the chip you already have on the PCM you already have, with the sensors and instrumentation you already have not knowing this 7.3 from any other. Your program would just neutralize ICP in the strategy. Better yet, you could use a variable voltage to the ICP sensor circuit to purposefully have say a valet mode on a switch, or to blip the throttle on shifts, or to have different amounts of fuel on a twist knob with 2 or 3 settings that coincide with different voltages that the PCM sees as 500, 1000, 1500 psi and puts you into different parts of the pw map. Pw map would have corresponding little terraces in it matching each jump. Imagine the PCS sends a voltage on an analog output to this ICP circuit that tells the PCM you are always at 1000 ICP, except right on the shift it sends a "blip" command on upshifts that tells it 500 ICP for a few milliseconds that corresponds to a 30% drop in pw/engine power for an amount of time determined by you for each shift.... On a downshift the PCS could "blip" the ICP circuit to read 1500 psi and ADD say 30% pw for a few milliseconds to smooth the downshifts... Basically..... the stock electronics are very down to party with MEUI..... it's just EUI as far as the truck is concerned. [/QUOTE]
