Does anyone have a copy of the chart that shows the Resistance vs. Temperature for the GM IAT sensors? I remember seeing it recently in a post somewhere but I can't seem to find it again....

Thanks,
Rob

Start with a 4.7k resistor. The more ohms the more timing advance, tricks the computer to think it is colder outside. Just experiment with different ones. I used them for awhile and had some good results, more power and better milage for about 90 cents. Now I use EFILive.

7500 ohms at 40 deg f.
3400 ohms at 70 deg f.
1800 ohms at 100 deg f.
450 ohms at 160 deg f.

I have yet to see a table where this happens. Only thing I see is a table that pulls timing when IAT temps get high. Where is the table that adds timing? Now I see where you could edit the IAT correction table to do this, but in almost all factory calibrations I've looked at, the cells below IAT 98 degrees are always set to 0.

It's strange. I thought I saw a table at one time where this was evident. But, when I went back to look...all I found was a 2* advance over base spark relating to ECT.

I don't know about that. But I do know it worked. I tried a 8k ohm and I could hardly drive it. Bad knock and ping going up hill.

I've got it here.

For reference... this is the table from a 2002 F-Body .. as you can see, on a stock car the resistor mod will prevent the PCM from pulling timing but won't add additional timing... cylinder airmass is a PCM calculated value (more load = higher gram/cylinder)
