so no you dont know how? or no it wont work period.
i just got the idea from a guy on mitsubishi-forums that turboed his 420a and thats the way he dealt with fuel cut. if that doesnt work then ill buy a fcd from ya

Because the timing curve is based off a calculated load value, and the MAP sensor value is used to caluclate that value. a 1 bar sensor reads ~5v at 1 atmosphere. a 2-bar reads ~5v at 2 atmospheres (roughtly 14.7 psig) so running a 2-bar sensor, when you're transitioning to boost (1 atmosphere absolute, 0 psig, 1bar absolute) the ECU will think you're around 15in.HG of vacuum, the calculated load value will be all out of whack, the timing curve will be way off in right field, and bad things will happen.
