yeah just wire the signal wire into the emanage ultimate via the analog input channels (page 19) in manual clamp the voltage same as you would a boost cut in the afm etc..
i charge $550 to tune the emanage ultimate, PFC, Haltec, NISTUNE etc... i prefer to use a field harness on the stagea as it allows me ti wire it on the bench and gives the customer the option to remove it neatly if selling the car.
as for price the aus dollar is pretty bad so its getting dearer i used to do $1250 drive in drive out.
