Re: Type 44 Single Pass Intercoolers in US? Mac-07 ECU
The knock in turbo engines, IME, is much louder than the n/a engines. May
also be slightly higher in pitch.
FP cutoff, I use a seatheater switch in the center dash pod receptacles
for 'em. This switch is wired to the respective fp relay terminals from
the ecu.
