Timing retard box for boost, Nitrous or NA. (HOW TO) OK guys here is the deal.
Things you'll need:
LS1 Edit
Variable Potentiometer 0-10k OHMS
several feet of 18 gage wire
Autotap or equivaltent
1. disconnect the IAT
2. Connect wire to IAT connector
3. connect wires to Potentiometer
4. Mount Potentiometer wherever you want
5. With the motor not running, and the key on use auto tap to determine the temperatures indicated (in celcius) at various potentiometer positions. I dentify ten spots that correlate to multiples of 10 degrees C. (i.e. 40c, 50c, etc.) Mark these spots on the dial.
6. Useing LS1 Edit version 1.05 under the ignition tab. Go to the IAT vs. MAP table and set the timing, at the degrees you have marked on the potentiometer, to add or subtract timeing as you want.
7. Try it out! You should be able to manually make changes for Nitrous or boost based on your seting of the false IAT sensor.
For the POT I used a 10K ohm volume control from radio shack $3.

BTW I didn't come up with this totaly, its a shared logic from a post that 383LQ4SS and I worked out.
