This relates to the IAT sensor. It determines timing by sensing the incoming air temp. Colder air = denser air = advanced timing.Robuilt said:
what mod is this? I already did a forum search but could not find anything. can you please elaborate?
You can unplug this sensor and then stick a 100K ohm resistor into the connector instead of the sensor. This "fools" the computer into thinking the air is colder than it really is. This mod registerd 2hp when I dyno'd the first time.
Do a seach on "Puffin Box" for more details on a permanent hookup.
