EMU says that the factory MAP sensor only reads to just under 7psi.
If you want to monitor pressure with your 180mm pulley, you should probably get the Greddy pressure sensor. Failing that, you could use the TPS as the load refferance. I did that for ages on AFM 4AGZE. It's a slightly dodgey method, but it's pretty reasonable on an SC engine, but it should never be done on a turbo'd engine.
EMU has it as group fire (2 inputs-2outputs)
Distributor type.
The EMU only has 2 inputs. Water temp input is required if you want to use the autotune function (wide band AFR meter required), as the EMU has an adjustable minimum coolant temp setting before it performs any autotuning. This allows for any coolant temp enrichment to be completed so the EMU isn't trying to correct for rich running, cold engine.
Word around the forum is that the knock sensor isn't particularly accurate on the 4AGZEs. I don't use it myself.
I'd be much more inclined to use the IAT sensor. Especially as you have the MAP sensed ECU. If you fit a more effective intercooler or water injection, it will allow you to use the IAT maps to change ignition timing and fuel.
Hope that helps.
