Do you mean without a converter? No its not possible because the EEC is looking for a frequency input not voltage and there is no way of changing that with a chip/edit.
I really do think you are wasting time on this, you may get it to work but I doubt you will without multiple tunes and at around $100 per tune it will add up quickly. If chiptorque have full support of the EECs which I doubt they do, there are far easier ways to do it with similar results. Also even if you get the MAP converter to work you will have to alter so many maps in order to keep the engine functioning properly because the MAP sensor is used for multiple calcualtions which will be thrown out with the addition of a boost reading. I am also not sure if you can alter everything needed using a chip alone.
Anyway if you want to continue continue, the MAP outputs frequencies in the range of 80hz to 159hz.
