[font size="1" color="#FF0000"]LAST EDITED ON 06-Jan-01 AT 01:43 AM (EST)[/font][p]I've heard that that Ford's EEC-IV computer will eventually "learn" it's way around performance chips making them basicly useless until you reset the computer again. Do the Superchips have this same problem?

The Ford EEC-IV computer does not have a closed loop spark advance system. That is, it cannot detect what the final timing actually is, and so cannot compensate. The fuel-air ratio IS closed loop, but only on partial throttle operation, not WOT (Wide Open Throttle). So the acceleration mods would not be compensated away. But the crusing air-fuel ratio that (in part) determines the gas mileage improvement is in the closed loop control, and the computer does try to compensate here. I have no idea if this interferes with the chips effectiveness.
Just my two cents.

Danny. I have a 92. 5.8l efi. Your saying a chip will give me about 20hp and 45ftlbs of tq and it will increase millage 1-2mpg at the expense of buying premium gas? And this chip is the one Ken sells? Is there any difference in the various chips on the market? The engine is rated 200hp and 310ftlbs.

Daywalker: The chip will imoprove your mileage 1 mpg, at best. These are not sold to improve mileage. Even at 1 mpg gain, it would never pay for itself because of the price difference between regular and premium fuel. Yes, these are the chips that Ken sells here in the online store.
Thanks

Danny, I tried a Hypertech module. No gains! What does superchip do that Hypertech cannot? Will it ping? I believe stock torque specs are 390. what kind of increase can I expect? I understand that with the computer my application has, there may not be much that can be done. I already had the tranny rebuilt, and a H.D. shift kit installed, and that works really well.

Jiml: Yes Superchips will remove the speed limiter on your Ranger.
To answer a question posted earlier. Your computer will adjust certain operating parameters to a certain degree. It can not , however, adjust the settings enough to accomodate premium fuel. This is where chipping gains the horsepower. And no, your computer will not adjust itself around the chip. Ford uses the same basic ecu in all their vehicles since 1984. Ask any powerstroke driver if he thinks that his power is decreased after a couple of years. You may become accustomed to the added power, but, it is still there. The dynos do not lie.
Now for your 460: That engine is listed at 240hp. The chip will raise that 24hp and 45 ft/lb torque. It is not advisable to use a stock chip in conjunction with a shift kit. The fluid pressures would be raised too high, possible damage. We could write a program eliminating the transmission pressure phase.
Thanks

Danny,
thanks for the response. Soon I'll be purchasing one for my truck through this site. That is great that you are offering people here a discount.
I'm still confused about the gas part in conjunction with the chip. Isn't it necessary to run premium fuel with the chip, or did I read your response wrong? Should that have read "it can not adjust the settings enough to accomodate LESS THAN PREMIUM fuel?" Hopefully you (or someone else) can clear this up for me. Thanks.

Jim; I'm sorry, I was answering 3 questions in one post. Someone asked if the ecu would compensate for premium without a chip. My answer was that the ecu can compensate a small amount, but, not enough for premium fuel. The chip changes the settings in the ecu to run premium fuel. Feel free to call for further info.

Redeye: It depends on what mods you are going to do. The mods that require a custom program are: Supercharger, larger throttle body, mass air, speedo correction.
Mods that do not require custom programming are:
Headers Exhaust system, Intake systems, dual exhaust.
It really makes no difference when you chip your vehicle unless you are planning major mods.

Hey danny, thanks for all of your imput. I don't mean to make you sound reoetitive, but here is a question for you. The chips typically add about 10% to your horsepower right? Is that 10% of the bast engine horepower or is it 10% on top of what you currently have? I've got a K&N and dual exaust which ads about 20-22 horses, so will I get those few extra horses? I'm running a 99 f150 v6 4.2 L. Also, I'm looking into lowering my truck for performance, can you give me any info on that? No one seems to talk much about that in the message boards. I DONT want a low rider, just a truck that sits more aggressive. If any of you want to help me out as well that'd be great. Thanks in advance for the help...

Brad: The chip will add 10% to you present horsepower. I am not sure exactly how much the exhaust and filter add. The chip actually works a bit better with those mods. An engine is nothing more than an air pump. The more air that you can pump, the more horsepower you can make. The chip will read the increase in intake air flow from your mass air sensor and adjust the fuel accordingly. The exhaust allows the truck to get rid of the additional air and burned fuels a bit more efficiently. Remember, you will need to use premium fuel with the addition of a chip. Most vehicles see a slight gain in mileage, most likely not enough to pay the difference between regular and premium. To most drivers, the added performance is well worth the added fuel costs.

Danny,
Thanks for the information...with dual exaust and the chip will I be able to tell right away the difference in power? The exaust system adds about 15-18 horses, and the chip would add about 20 I assume, so will adding 35-37 horses be enough for me to notice considerably? What do you think?

Most drivers can feel a 10hp difference in a truck. I am not sure what your expectations are. It will not turn your truck into a tire scorcher, but, the added power will be noticable. The chip will also raise the rev limiter between gears.
Thanks
Danny
