I have LS1-edit and I use an 150 shot of nitrous. I wanted to setup a timing tricker system that retards the timing with the nitrous activated. The highest IAT setting is 90*C. Has anyone tried this?

Yes, absolutely.

Just make sure that you size your resistor correctly.

Connect the resistor to a relay circuit so that when your nitrous engages the relay has the car use your resistor for IAT rather than the IAT sensor. It should pull about 3 degrees. If you have edit, you can edit the MAP/IAT table and get it to pull as much timing as you want.

Good Luck,
Kevin

OK, does anyone have a resistor value that I can start with?

Anyone?

here are some resistance to temp values;
9420 ohms = 32 *F - 0 *C
7280 ohms = 41 *F - 5 *C
5670 ohms = 50 *F - 10 *C
4450 ohms = 59 *F - 15 *C
3520 ohms = 68 *F - 20 *C
2796 ohms = 77 *F - 25 *C
2238 ohms = 86 *F - 30 *C
1802 ohms = 95 *F - 35 *C
1459 ohms = 104 *F - 40 *C
1188 ohms = 113 *F - 45 *C
973 ohms = 122 *F - 50 *C
667 ohms = 140 *F - 60 *C
467 ohms = 158 *F - 70 *C
332 ohms = 176 *F - 80 *C
241 ohms = 194 *F - 90 *C
177 ohms = 212 *F - 100 *C
132 ohms = 230 *F - 110 *C
100 ohms = 248 *F - 120 *C
77 ohms = 266 *F - 130 *C
60 ohms = 284 *F - 140 *C
47 ohms = 302 *F - 150 *C

i am not sure how many degrees of timing
these resistance values change but,
i know the more the resistance,cooler temp
the more addvanced the timing
you are wanting to retard your timing so you
will ues a lower resistance and a higher temp
to do that.

"5670 ohms = 50*F - 10*C" = about 1.5 degrees of timing addvanced over stock timing.

sorry i did not know exactly what resistance
to use but i hope this helps.
good luck!

if you have A-TAP, or EFLIVE you could use
that to see which resistance value
dose what timing degree, by tring
differant resistors.

Thanks, I needed a resistor value to start from.

cueball

you mite try a 667 ohms resistor to start with
unhook your IAT sensor and put it in the conector
and see what that does.
check you timing to see what it is with that resister.
good luck!
