I have a 2002 156TS Lusso, and recently bought a device which basically is a POT that changes the resistance of the signal from the IAT sensor. Which would increase the fuel requirement, thus more power.
I believe that the 156's dont have air intake temp sensors but relys on the MAF sensor, which has 4 wires. Does any one know the wiring for the MAF as I want to wire into this to complete this mod.
I also put in a Hiclone, which is the european equivelant of the Turbonator, was a bit sceptical about it, but got one on the cheap, wow what a difference in the performance and throttle reaction throughout the revs, also fuel economy jumped up dramatically on open road running.
However if your frequently caught in traffic or running about town all the time forget it as it will starve the engine, and fuel eco goes up.
