The same method is used for boost. Set the "thres" and "gain".

1. You need to cut the IDC link on the underside of the circuit and solder link the MPS. The system is now solely based on MPS.
a. Move the IDC jumper link over to MPS.
b. If you don't have MAP sensor on board, you need to purchase one.

Rest of your questions:

2. Smaller filter less than 50um will clog quickly. The filter supplied is for the jets, not intended for the engine.

3. Not normally, depending on who you purchase the system from. Some suppliers only sell kits. If you purchase from aquamist directly, we can credit the standard jet against the filtered jet. But the filtered jet only apply to the smaller 0.3mm nozzle.

4. The smaller jets comes with three flow rates A, B or C (commonly supplied). C+ jst spray a bit more. For aquamist, you can specify the preferred flow rate, we can make it for you at the same price.

5. The casing is zinc plated steel, in time, it will rust as the Zinc plating depletes. The cable gland must be sealed or water will trickle into the pump and corrodes the bearing.

6. If the lube is hydrocarbon based and gets into the aquamist system, it will destroy the pump and valve within mijutes. All rubber seals are EPDM based, it will swell up like a balloon when in contact with any hydrocarbon.
