Anyone know what the resistance for the IAT sensor values are at certain temps?

I searched and only found one person who posted some. Just want to make sure they sound right or if anyone knows if they're wrong since theres not much info I found.

I found some resistances for a civc, but they're very different from the numbers below.

This is not a common question. If you really want to know if they are correct, you may need to find an s2k in good working order in your area and test them.

go to the FI forum. Camuman, or someone like that did a test of the stock IAT sensor and got back temp and voltage numbers.

What are you doing that you need this information? It is voltage that you will see, not resistance.

This one? Its cool info, but not what I'm looking for. Thanks though.

I'm probably gonna get shit for posting this, but you asked so here it goes.

I'm trying to do the opposite on what the stupid ebay "chips"/resistors do. I want my ecu to retard a little timing by thinking it is getting hot air. LSx guys do this mod for nitrous and it'll retard a few degrees of timing. Depending on the engine, LS1s can retard up to 3 degrees and I think LS6s can retard up to 8 degrees just by the IAT sensor. I doubt the s2000 fuel tables are altered by the IAT, but I will have this on a wideband to be positive. My timing mark on my spark plugs is a little aggressive, but still fine. I want to see if, with the same shot, I can get another mph or two in the 1/8th mile(no 1/4 near me), just by getting my timing right.

Saving up to buy a Greddy Ultimate, but for the moment, I wanted to try this out and I can take it out when I'm not at the track. Not the correct way to do things, but I want to see if it'll work. I will be testing this the correct way by correctly pulling and reading my spark plugs right after a run just like I do when I normally read my plugs for nitrous.

The worst that could go wrong is I could run a worse time since I have already ran a higher shot (80 compared to the 70) so I have at least a little room to play with for error. With the 80 though, I ran the same time with a worse MPH since the stock timing was too aggressive, but still not enough for detonation. Since I will only try to retard my timing, I will 100% not get any detonation from doing this.

Harris Speed Works makes a tuning system for LSx engines on nitrous and they use that too to control timing.
