Message: [QUOTE="Diabolic, post: 1429657, member: 18314"] It seems that the pcm sends a signal to the IPR based off the tps and map sensor. The ecm commands a certain pressure based off the map and tps. The ICP reports back if the requested pressure is being achieved and the end makes adjustments to the IPR if it isn't getting what was requested. Is this correct or do I have that backwards? If I am correct then at wot, how can you have an ICP pressure of 2500 and IPR% 35? To me this indicates the ICP is reporting back the commanded pressure has been reached. Does that mean the ECM is only asking for 2500psi? If it was asking for 2800 and only getting 2500, then the ICP would go higher than 35. I assume the commanded pressure of 2500 at wot is from the end and in the tune it can be bumped to 2800 or 3000? [/QUOTE]
