Message Couple of things:

1) It is worth noting that their safe injection system will catch both a stuck nozzle as well as running out of water. Certainly a big plus.

2) If you're using a dual MAF, then you're using a device to read both and re-map to a single MAF voltage for the ECU as you can't really modify the VQ table without sacrificing either resolution or max airflow. I'd say MAF is far more important than MAP if you *had* to choose. For example, I make full boost at 3200 RPMs yet my MAF translated to airflow more than doubles. by the time redline is reached. Obviously this is not a good application for a MAP only system.

BTW, you can use the MAF system they have and use an inline flow restrictor with a vacuum line that decreases restriction based on MAP. You can set it to whatever your maximum boost will be so that at 0 psi, your water flow will be restricted by x psi. Once you reach x psi(your maximum boost), the flow restriction will reduce to 0. I talked to Dan about this at Snow and he had no problem with someone doing this with their system but also mentioned that their new controller in the spring will have a MAP transduecer built in in addition to the MAF 0-5 volt signal input.
