resistors with IAT

[saltnvinegar6287]

Hello everybody. I ran a search and found some info about putting a resistor in series with the IAT, but now have some questions about it. I know it advances your timing since it thinks the air temperature is colder, but does it lean or richen the mixture?

A second question is just a subsidary one. I read a test and found that adding around 10K Ohms of resistance advances timing about 5*. Is this enough to have to use premium gas? Stock computers are programmed for regular, so i wouldnt want to trick the computer with too many things before I program it right.

if you searched like you said, then you should realise that 3.8's tend to not see any gains with it, where as the 3.4's do. FYI

as for your question, I don't know the answer lol

They go for about $0.15 over at radio shack. This guy should be smacked for selling these for so much!>http://cgi.ebay.com/ebaymotors/ws/eB...954988899&rd=1

I know. did mine myself, but I think im taking it out for these two reasons.

1. It advances timing and since the intake air is warmer than the car thinks, you are risking detonation.

2. It richens the mixture, and will have negative effects with the warm air that is coming in.
