I have a hypertech chip for my 93 (not installed at the moment) and I can tell for you that you won't notice a difference if you run anything less than 93 octane. With gas prices the way they are, mine may never go back in. Out here California the highest octane gas they have is 91, so I used some ocatane booster, and it worked, but that stuff ain't cheap either and I worry about what kind of additives it has in it.
The way I understand chips is that the stock computer program will ignore higher octane fuel, and retard the timing so that it still generates the same power as the 87 octane it was designed to run off, of so the only benifit you get is cleaner buning fuel and maybe less engine deposits. The chip intercepts signals before they get to the computer and tells it "HEY DUMMY YOU HAVE BETTER FUEL USE IT!" So basically all it really does is tune the spark and timing for higher ocatane fuel, which will make more power, but if you try not using higher octane fuel you'll get engine knock "detenation".

I have a Jet chip in my 92 apparently. It was supposed to be fitted when I imported it from CA. We have 95 octane fuel here so I guess it may use it but I am told that the JET only modifies the ECU map on WOT not cruise or idle so unless you go everywhere with your foot on the floor it won't make any difference. Chips like Superchips modify the map over the whole throttle range and thus will make a difference during normal use.

i suggest spending that money on a good flowing exhaust and other mods. the efi systems on the new rigs out there touch more aspects of the engine vs what we are all driving so there is no real benefit.

Put a JET chip in my 96 Bronco some difference but need to run high octane fuel.
I also have my chip removed now. cost of fuel vs. minimal performmance change not worth it.
If I were to do over. I would not install the JET chip.

I did a lot of research on this one, unfortunately AFTER I had wasted the money on a JET chip. I discovered that both JET Chips and HYPERTECH programmers function only at WOT. This was confirmed through both email and phone calls to their tech support folks. Unless you plan on running around with your foot on the floor all the time, the programmer you are looking for is the Superchips 1715, or have a custom chip burned for you.

A 96 will have the OBD II electronics, so you can't use a chip. Instead you use a power programer that has the original ECU programing permantly stored on it. Every time you use the programer you are re-writing the programing on the ECU. If you want to return to stock settings the power programer uploads it back to the ECU from it's permanent memory. The advatage of OBD II electronics and power programers is that you can do things like change the rpm of a shift point, remove the rev limiter, and remove the speed limiter, in addition to all the things a regular chip does, plus you can check and clear codes with it. It plugs into the diagnostic port under the steering wheel.

Interesting, I was under the impresson that an OBD II system didn't have provisions for a chip. I do know that Hypertech makes a power programer just for the 96 Bronco. This maybe the difference between the early OBD II(A) setups and the newer OBD II(B) systems. I just reciently heard of this so I don't know any of the specifics.

You can chip any OBD II computer, but you have to live with the program or remove the chip, nothing in between. With the programmers you have control over what options you choose to use and you can remove the program any time you like. The Hypertech programmer has the same problem as the JET module, it only modifies your fuel/air/timing curve at WOT. Unless your foot is on the floor, it does nothing.

I was just told yesterday by the good folks at 4WheelParts that Superchips 1715 will not work for the 96 w/ 5.8l. The only programmer available is the Hypertech Power Programer III. Is anyone running the Hypertech on a 5.8l and if so, what are your results?
