Ever since Honda started using flashable ECUs in the most recent generation of cars, reprogramming Honda ECUs is a piece of cake. Just connect an OBDII cable to your programmer, press a button and your ECU is reflashed. One caveat is that Hondata spent a year or two decoding the fuel map codes.

My neighbor has been looking at chips for his VW 20th AE GTI, many of which can be reprogrammed with the light switch, turn indicator arm, etc. Around here most of the guys who install stuff like that on the weekends work at the VW dealership, so they'll know your car when you bring it in, but on the off chance you get a strict tech working on your car, he's not gonna like the fact you changed the engine timings and ran 104 octane racing gas through your pipes. Switching the settings back to normal and keeping everything somewhat secretive can keep the dealership from using that reason to avoid warranty work on your vehicle.

    According to the article, mod chip have two categories:

    Normally aspirated: Add a small bit of horsepower (normally less than you can feel in a double blind test) and lose significant mielage.

    Turbocharged: turn up the boost, wear out the engine in a hurry.

    What the article doesn't point out is that over-boosting your engine will cause it to wear out in a hurry. The engines in today's cars are built to handle a specific amount of power, and when the power is increased the wear on components is exponentially increased.

    For those curious, our head engineer tells me that there is a cubic relation between engine RPM's and stress. Stress causes wear, and that's not a linear only relationship either.

    When stress exceeds a certain value, BANG + expensive crunching noises happen.

    ----
    Back in the good old days, re-chipping your ride could actually help (though not always). However, as the engineers learned more and more, the cars got better and better. Also bear in mind, performance is very important nowadays. The factory is getting all the performance it can out of tuning cars, while keeping mielage and wear in check. Also remember that these engines were designed for performance from word one.

    The only reason to start reprogramming the engine controls is when significant hardware changes have been made.

    As to the "Premium Fuel" thing, I'm doubtful, since all engines i've ever worked with use knock sensors, and are always running at the ragged edge of detonation anyway. There's quite a bit more involved than just fuel octane. Different formulations of fuel from different gas companies burn differently (gas is actually about ~40 or so chemicals in a cocktail). Altitude, engine temperature, air temperature, humidity, air filter cleanliness, RPM, engine load, and spark plugs all play important roles in detonation.
    Consequently, the chips are continually adjusting for all that. Supposed octane levels are just one more factor. Granted, some cars, like the Acrua NSX :) demand 91 octane anyway, but that's due to engine compression issues. You don't need a chip to take advantage of premium fuel, just a good OEM computer.

    Like our head engineers always says: It takes a lot of work to outsmart factory engineers. And several million dollars.
    • That's not true at all. Many cars are built to handle way more HP than they come with from the factory. Why? Emissions.

      You can get an extra 30-35 HP out of the Evo 8 right off the lot with a reprogramming of the ECU. Many performance cars are the same way though this is an extreme example.

          False. The EVO has an extremely strong engine that can take insane boost pressures. It has a cast iron block and has been developed for many years now. 35HP is not unreasonable, and won't significantly reduce the car's life expectancy. You'd be far more likely to wrap it around a tree than blow the engine.

          Those two extra cats in our WRX-es are not needed, once the engine warms up. The first cat in the pipe up to the turbo charger is just there for cold start, as is the second cat. The sucky thing is that once it warms up and they aren't needed, they still present a parasitic loss in the exhaust that hinders performance in a big way.

        It's already tuned for maximum mileage and reliability. You just have to keep up your end of the bargain.
      • For most cars, 200k miles is no problem if the vehicle is properly taken care of.

      Um, have you actually looked at reflashing in this millenium?

      The tuners are getting very adept at reclaiming the extra power that the factory left out due to emissions and fuel quality problems. They spend days reverse engineering ECUs and trying things out on the dyno. It's very complex, but the rewards are numerous.

      I have a Subaru WRX with a remapped ECU. With no other mods, I get 30 extra WHP from this. I do have to run 93 octane, but I did anyway because 89 is pure, unadulterated turpentine. The WRX is turbocharged, but interestingly enough they only increased the boost pressure by about 1PSI (from 15.1PSI max). Everything else comes from the timing and environmental correction maps. I also get slightly better gas mileage, as long as I'm not running wide open all the time.

      When an engine detects knock, it will retard the ignition timing, which decreases your power output. By running better fuel and reflashing the ECU to take advantage of it, you can run hotter timing and get around in a hurry.

      The Audi A4 1.8T is in a similar situation, where a chipped car will be significantly faster than it was from the factory, with no real decrease in engine life or reliability. The factories are leaving a lot on the table because they have to deal with a wide range of horrible fuels, awful drivers, and insurance companies.

      Note that both of these cars are meant to be fast. Reflashing a Taurus or Civic doesn't really do crap, because they were designed to be efficient and unexciting, so there isn't much left to do but add a lot of external modifications. There are also some cars that are tuned to the ragged edge, like the Nissan 350Z. No one has managed to get significant gains without major modifications, such as forced induction.

          OK, 25.5. Let's call it a rounding error. 4.5HP difference could be attributed to different air temps or humidities or crappy gas or any number of things.

          This is also on an AWD car with relatively large (30%) drivetrain losses, so the increase at the crank is even higher.
    • My understanding is that premium fuel should improve things if the manual suggests using it, and even if the car can take the lowest grade at the pump. What an engine computer does with lower grades of fuel is detunes the engine timing and such so that it doesn't knock.

      With one car, my dad did find the most bang for the buck at midgrade, by I think 5% or so versus low and premium grades.

    I can understand this as a hobby, but why mod your day-to-day car so heavily? You probably break several laws in doing so, you definitely invalidate your car lease or warranty, and you probably invalidate your insurance as well. Besides, how confident are you that you'd never screw up?

      I tinker with my car all the time. Back when I had an ECU I even understood (had the firmware source, complete with symbols and comments, don't ask how...), I actually tinkered quite a bit more. Blow up the motor? Oops. Not like I haven't done that before, and there goes a Saturday down the drain changing it out. I usually have a spare engine or two sitting around, or if not I know where the junk yards are or I know how to rebuild or repair them (if possible, depends on the failure mode).

      Car Lease? Warranty? What are these? I buy cars for cash (usually used, or occasionally built from 2-3 salvages) and drive the suckers into the ground, then repeat. My Blazer died at 190,000 miles (original engine, third tranny), my del Sol is still good at 160k and should live to well over 200k, and my Yukon is at 110k and is only three years old (only vehicle I've ever bought new). Yes, I drive a lot. Greatest feeling in the world to me - open road, open windows (or open top), radio cranked up, going places just to see what's over the next hill.

      Also, how exactly do I invalidate my insurance? I don't carry coverage for repair on any of these, except the Yukon, and that's only because it's new enough to be worth fixing. The rest, after any wreck my insurance would have to pay to fix, I'd either cut up for scrap or fix them myself anyway. If it's the other guy's insurance, obviously I'm going to make them fix it (or just take the money and scrap the car). It's not like I'm stupid enough to ask the insurance people to fix something mechanically that's my fault through stupidity.

      Chips are just a new piece of everything that's been done for years - overboring cylinders, performance cams, high flow exhausts, aftermarket blowers, etc. That said, though, chips on normally aspirated cars are usually a waste of time these days. Don't bother - work on the other upgrades instead.

      Guess it all comes down to if you know what the hell you're doing, go for it. If you don't, don't be a wannabe wanker that complains when it doesn't go right.

    chipping a car is really not that crazy or extreme. Most cars come from the factory with "stupid-proof" setups, i.e., they run very very rich so you can't induce detonation and blow your engine easily, and they engineer in lots of understeer for safety reasons since 90% of the people on the road aren't what you'd exactly call performance oriented drivers.

    chipping a car mostly involves re-doing the fuel injector maps and spark timing control for certain rpm ranges to increase torque and horsepower. This has the added benefit of also increasing fuel mileage in many cases, since it's set to be very rich from the factory. When you lean it out a little, you use less fuel, get more power, and have fun in the process.

    Most factory turbo cars that I know of don't really use electronic boost control mechanisms, they actually use wastegates and compressor bypass valves to maintain boost in a mechanical/pneumatic fashion. Electronic boost controllers are pretty expensive, anyway.

    but just reprogramming the existing chip in a car is nowhere near as good as installing a complete standalone Engine Management System. With an EMS like a Haltech (produced in AU, btw), for example, you can actually adjust fuel, timing, boost, etc literally on the fly, unlike a reprogrammed ODBII type computer found in most cars. This allows you to fine-tune your car for maximum efficiency or power, or whatever you're looking for. (power, of course, duh!)

    You'd be really suprised how over-engineered a lot of cars are, and what they can take. Hmm.. sorta like overclocking a processor, really. If you take the proper precautions with each (better cooling, faster ram, good power supply, for the computer, or higher-octane fuel, good lubricants, and regular maintenance for the car)

    So before we get our panties in a bundle and start completely ranting on the car tuner demographic (but it wouldn't really be slashdot without it) just keep in mind that it's the same sort of compulsion for car tuners as it is for overclockers, or mod-chippers, or kernel-hackers...

    • chipping a car is really not that crazy or extreme.

      Nope. But it's like overclocking without attending to CPU cooling.

      I'm going to show my age, but "back in the day," one didn't do serious cam or intake mods to a 2-bolt main small block Chevy. One sought out the tougher 4-bolt main blocks.

      Same applies to a Civic or Eclipse. You can get them to pump out horsepower far beyond what their little crankshafts & main bearings were intended to support. Throw a nitrous bottle in the back & you're talkin

    It's increasing complex business - I know someone that works in it - simply "rechipping" doesn't work in modern and complex engines.

    The new devices effectively clamp around your Engine Control Unit (ECU) by intercepting it's inputs and outputs: the box modulates the signals coming to and from the real ECU: for example, the ECU will usually consider it an engine fault if (say) emission is too high, so the purpose of the device is to (a) alter the fuel mix ratio output on the one hand, but (b) fool the input back into the ECU that the emissions aren't as high as they really are. There are many variables, the ones I've seen take up to (say) 16 different variables that can be manipulated.

    I'm told that the devices need to be tuned for the specific model of car, and preferably, the specific car itself: as individual cars each have different variances and tolerances within the scope of the model itself; and the tuning software isn't released to the public (even though it may escape ...) on the principle that the makers of these devices don't want people to buy the device then try to home tune it and blow their engine up. The tuning is done inside a workshop with appropriate monitoring tools (e.g. analysers), so they can trim the tables in the software, and observe the outputs on the tools to ensure that the best results are obtained without going too far as to break the engine. Naturally, there are some people who do have their own tools and workshops and are competent do this themselves, but a lot of these modders don't.

    This definitely voids your warranty, not to mention probably breaking environmental and other regulations, if you do it to street machines. That doesn't stop some people though. (there's a good analogy here to the issue over releasing drivers for 802.11g chips: because the software in the driver is part of the overall FCC emissions approval, so altering the software potentially voids the approval of the device -- similar concept here in that manipulating your ECU voids the grounds upon which various approvals were made)

    However, it also has more legitimate applicability to track machines (based on stock cars) where it's not an infringement of the regulations because these are on private raceways and with specific exclusions and so on (and, these cars are usually modded beyond the limits of the warranty in the first place).

    The manufacturers are getting wiser and building in measures to defeat the devices, but it seems to make these guys money, and in the same way that you can often safely overclock your CPU, you can often do it to your engine: just need to be aware that (a) it depends on the specific car itself, (b) it doesn't always work, (c) when you do it, you're taking a lot of risk as by definition you may be working outside of the engineering tolerances/limits of the engine [unless the engineering is there, but commerical and marketing considerations limited its scope].
