[Miata] 2001+ Miata - IAT sensor mod - Timing

[Bryan Wyatt]

You would probably be better served actually finding a way to get colder air into the engine than trying to fool it into thinking that it's the case.  I'm not sure what mods you have, but that's just my opinion.  NA's generally ran pretty rich from the factory, but I'm not sure at all about NB's...

  What are the opinions here of the little "add a resistor into one of the wires going to the IAT sensor?"  not replacing the sensor w/ a resistor, but adding one to the line, to make the computer think its colder than it really is. I was under the impression this would make the car run rich, but its said that it alters the timing more than the a/f ratio.  Which I guess makes sense, you still have the O2 sensors, which should, in theory realize its a tad rich (as compared to stock) and lean it out a bit (back to stock presets)...thoughts?  

Some of the 2001+ guys on miata.net are saying good things, so I'm curious.  Not to mention I'm bored...
Thanks
