You've probably seen them on Ebay for 28 bucks + shipping. They are resistors in a plastic box that you wire up to your IAT sensor. Supposedly they advance timing and air/fuel is adjusted. Sold as custom for each make - Jeep, Chevy whatever.
I read the feedback on some of the people selling these "boxes" and the reviews are mostly good at least in terms of shipping timliness :lol: Nah, but it's the usual 2mpg mileage drop and I guess some performance improvement. May or may not have to run high octane fuel. Some question about whether the performance improvement lasts or whether the ECU returns to stock after a period of time.
(I know you can do the IAT mod where you relocate the sensor away from the intake/exhaust manifold and technically lower the termperature received at the sensor) Think there was a post on this subject here before but I couldn't recall any search terms.
Think these IAT box things are called, White Lighting, Juice Box, etc. No chips for the YJ 2.5s so thinking about it.

I still have not gotten a chance to get one of these yet but i plan on it. Only real way to "Chip" a YJ that i know of.

Search for the thread on the IAT sensor. It is relocatable. As for the $0.5 resistor, I'd rather not pay $28 dollars for one. You can usually get 100 packs for a few bucks. I don't believe it will change timing though. When it's colder the IAT will tell the engine to enrich the fuel mixture.
