hfs4 and megasquirt

[ewillard]

i have final made the jump and will be adding water meth to my setup.
1990 vw corrado with a 2l16vt motor
1000cc rc injectors
gt3582r
ms2 3.57 board
car made 490whp at 20psi
i want to be able to turn it up to 30+ depending if inj have enough

i will be doing 2 .9mm jets one directly after the turbo outlet and one directly after IC. i have air to water intercooler and only have about 24" of boost pipe. the outlet of IC is connected to the TB with silicon connector.

basic wiring is no issue the issue im having is making the correct modifications to the HFS-4 controller. if i need any.

1) is the map seneor input the ECU has a 4bar map 0v=3.5kpa-5v=416kpa
(http://www.diyautotune.com/catalog/m...ion-p-117.html)
2) not sure where to get the map signal from sense the sensor is internal in ECU.
3)waste gate fail safe for electronic boost control. to go to gate pressure on meth turning off or begin interrupted. i have a gizmo ms-ibc uses mac valve. im reading using the brown and white wires on gray harness to just splice one of the wires going to the mac valve?
