Is it worth installing a performance chip in a 1992 Jeep Wrangler Renegade with a 4.0l HO engine with a 5 speed manual tranny? ---

What’s your goal? The chip may improve top end power, but will make fuel economy suffer. Sometimes the fuel economy suffers more than it is worth. ---

Maybe if it was to go in a Toyota. It’s not worth the effort or the money. ---

There are many worthless ‘chips’ out there, $60 and a couple of wires. If they’re making outrageous claims (50% more horsepower and 20% better milage!!!), it’s obviously worthless. ---

That old Rambler Motor is not going to perform much better than it already is. Save your money and don’t try to teach an old dog new tricks… ---

It gets bad enough fuel mileage as it is now. If it’s just for top end power it isn’t worth it. Thanks for your help. ---

With the sudden acceleration problem they have Toyotas don’t need one! They need a Brembo brake chip! ---

No, it is not worth it. That '92 has a relatively unsophisticated system, and the best a chip could hope for is to offer a bit more injector pulsewidth for a given oxygen sensor signal. It’ll have no control over spark timing. On that engine, with that vehicle, the only difference you might notice is a drop in mileage.
