on ebay there are some racing car chips that will increase your hp which are the real thing?

Answer 1

There are computer chips for sale that have some pretty impressive claims. My own experience has been good and not so good. I installed my first one on a 1998 Jeep Wrangler Sport 4.0 and the performance gain was pretty impressive. However when I added a sport exhaust and a air intake system the performance was even better. I removed the chip and discovered that 90% of the performance gain was still there with the Air intake and exhaust mods. The thing I did not like about the chip was the 91 octane requirement. Considering the chip was the most expensive item I had purchased, I really did not think I was getting the full "bang" for my buck.

a guy answered this for me and here is his quote...

and don't go with the chips
they can screw up your ecu and cause a lot of probs
and the JUN and rc spec are programmed for a certin set up it won give you ne hp or tq unless you have the EXACT same setup

what i mean is that the companies specifically calibrate and setup their cars (sponsored, ect) to make asmuch power as possible and save it to a chip in the ecu.
the setup is vastly more different than any near stock configuration, they have componets that are made and bred from racing exp. The motors they run have componets that are made to make power ( such as oversized valves, custom made pistons, valvesprings and camshafts), that the stock motors don't, the setup is specifically tuned for thease componets. an example is the amt of fuel turbo motors consume vs stock motors. turbo motors need more fuel to prevent the a/f mixture from leaning out and detonating the motor. this demand of fuel cannot be delivered by stock injectors and a stock fuel pump. the parts are upgraded so that they can flow that amt. In other words the "tune" of a car depends on what kind of parts and "work" a motor has had. demanding a stock or partially stock setup to thease lvls can result in you losing fuel econ, reliability and even the motor it's self. Thease chips are programmed for the companies cars and have been proven to make power in the exact same setup as the companies, BUT they have also been proven to reduce power and even detonate stock motors when added to stock/near stock setups.

when you buy something on eBay check to see if there is a user guide that you can read about that item. they will be on the left hand side of the screen. they are free to read they explain pro's and con's. some of the chips are just really a resistor. resistors are not chips. they have a lot of them on eBay. but they do sell real chips and re-programmers. resistors aren't worth it. you can buy one a radio shack. you can ask the seller if its a chip,computer or resistor. if he doesnt respond with a pic then dont trust.
