Therefore you should reset your ECU periodically after filling up full tank in order to ensure that ECU adjustments for its octane memory are made afresh corresponding to the octane actually in use. You can learn more about that here. STEP 1: Download the stock ECU load from the vehicle. When you get a new chip, the programmer has changed the program's commands of the ignition map and fuel map in response to a change in air flow and rpm (ie. Look for a good combination of price, power rating, and features. The Manufacturer holds the key to the ECU and locks their Map into their firmware. If you run into problems or don’t feel up to the task consider getting an estimate speaking with a reputable car stereo shop. For best results, make a small loop on the end where you want to attach your wire and wrap it well with electrical tape to smooth over sharp edges that may snag. In that case you have a few options: The 2nd option shouldn’t be necessary except in really tough situations. 250, 500, 0,0, 9, 800, 1200, 1600, 2000, 2400, 2800, 3200, 3600, 4000, 4400, 4800, 5200, 5600, 6000 and 6400. They are selling them based on the attractiveness of convenience for unsuspecting people who don't have a local programmer and dyno, the hyped hp gains from the magazine articles or ads, and a lower cost compared to other significant hp gain modifications, like cams or an intake manifold (IM). If it was really this easy to get more power from a car then the manufacturers would have already done that themselves. The idea is not to reset the ECU when using anything in your car that you normally don’t use. If not, check the following items for problems. Some only contain a fuse holder, fuse, power wire, ground wire, and the remote lead wire (typically an 18 gauge wire). With them, you can get clean, low-distortion music power at high volume. As I mentioned in my guide, I generally recommend using a multi-channel amplifier. But don’t worry, there’s nearly always a gap, hole, plug you can remove, or a rubber wiring harness seal you make a hole in by pushing a screwdriver or similar tool through. Be sure to remove the fuse before doing so, and install the fuse holder on the wire before connecting it to the battery. In some cases, poor driveability and performance are the result. If you can find a factory ground wire location in close range it’s an excellent ground wire connection point. Fuel injectors require more current to open meaning they run hotter and are less reliable as a result. Copyright © 2017-2021 SoundCertified.com. ... try moving it. Consider picking up a car stereo installation kit like this Scosche KT12A budget kit from Amazon. Generally the turbo/clutch weaknesses will manifest themselves clearly at this point. The amount of ignition timing and fuel delivery is changed for a given air flow and rpm compared to the stock program. Note that they’re generally great choices if you want good but not extremely loud bass in your vehicles. So what can you do? In the hex dump window you see a series of highlighted bytes, 43 7A 00 00, and in the Inspector window you see "Float  250". D&D Motor Systems is the premier EV motor manufacturer in the U.S. for a small to medium light-weight EV conversion.In addition we offer a complete line of U.S. made EV controller to go with our high performance EV motors (electric car motors). This is a serious investment for serious people. This is all good advice when buying any aftermarket devices such as ignition wires, ignition products, oil or fuel additives etc. Black fabric is available in a variety of fabric types (I’ve used black felt or velvet-like materials often for custom installations). Check out the software here. There are two types of EPROM emulators: normal and real-time. You may find it easier to remove the back seat and find a gap that will allow you to easily run the wire to the back. You can find some great ones I use here. This is the only way to go, if you are serious about getting the most out of a computer program upgrade for a street/race setup. If you want to go at this alone, then an AEM EMS is worth looking into, since it has base programs and laptop emulation. Find stories, updates and expert opinion. Can you handle it or do you know someone who can? Different generation ECUs may use the same characters. Accord and Prelude ECUs can use a letter and number code. If you’re going through a factory wiring harness seal as pictured in the 1st pic, push it through until you can grab the wire and then from there pull it through the engine compartment. This typically allows 4 x the power of a single channel to be provided! At each pair of speaker wires or near the speaker wire connector, strip off about 1/2″ of insulation and tap off it. Investing in a wide band O2 sensor like the MOTEC they sell is also a good idea. This is because the ECU has not been reset for higher octane. I don’t want that to happen to you. If you don't have a fairly thorough understanding of the system, engines and tuning plus a dose of patience, DON'T buy one of these. 3 Typical Questions When Attempting Car Tuning: First, don't chip too early There is no point in getting a new ECU program early in your engine build up and then later upgrading to bigger lift and duration cams, or larger injectors, bigger fuel pump, or an aftermarket IM/bigger bore TB , etc. What hardware, skill and tools will you require to install the system? I’ve discovered that while they’re sold in some amp kits and are also sold in parts stores. Once you exceed a 20% increase from the maximum FP spec, you wear out the injectors faster and the ECU fuel map calibrations for the program are no longer applicable. The reason you see so many chips for resale on eBay? I’ve covered this topic and show some great examples here. ROMs are read only memory, which cannot be re-used once programmed(e.g. Now let's dive more into the technical detail of tuning - but still keeping it simple... Back in the good old days, the task of timing the ignition spark was performed by the mechanical distributor. Real-time EPROM emulators allow you to changetuning information while the engine is running. For the average person, an amplifier capable of producing 150W for use with a well-matched subwoofer and speaker is adequate. It comes with a chip burner, chips ($25/each), emulation laptop capability, instructions, and tech support. This can result in “bottoming out” early (the speaker has little resistance to movement and begins to reach its limits when moving) or simply can’t produce bass sounds at a normal volume. The ECU response will continue to correspond to lower octane even though you have started using higher-octane fuel. This is when a programmable system is a must. Modern day cars do not have manual controls. Generally speaking, you should still be able to add a subwoofer by tapping off of a pair of factory speaker leads in most cases. Some Basic ECU Info for OEM Honda ECUs. Place the fuse holder near the battery with approx. more speakers in the future and expand your stereo system, think about buying a 4-channel stereo. Bundle your power and cable wires together neatly like this. So you want to make major power gains (ie. The greater the RPM, the more the timing would advance. These systems are great for the knowledgeable person and a nightmare for the lay person. 2. If all of this discourages you, sell the present car and simply buy a faster one, you will probably be happier in the end. Details here are emailed when you submit a NEW support ticket. A good amplifier wiring kit like NVX XAPK4 True Spec 4 Gauge 100% Copper Single Amp Wiring Kit with Speaker Cable, No RCA includes a  fuse, fuse holder, subwoofer speaker wire, power cables, remote wire, zip ties, RCA cables, ring terminals, and cool accessories. ), Wire stripper (not a need but greatly simplifies work effort), Run the remote wire to a +12V wire switched on with the ignition or the accessory position of the ignition switch (this is the 1st choice), Use a specialized adapter which senses music and when connected to a power supply can provide a remote lead signal, Subwoofer output jacks (often marked SUB or SUBW), If only 2 are available, then that’s fine as well, Make an amp mounting board and attach it to the car securely, Poor car ground wire (measure continuity between the amp negative terminal and a metal part of the car), Remote wire voltage is too low or +12V isn’t being supplied at all. Use the ring terminal to fasten to a battery clamp bolt or stud. Be wary though, as some piggy back ECUs and aftermarket ECUs do not include knock protection. Don’t spend excessive money on speaker wire as it’s a waste – you just need good wire. Or Dinan ECU - which are "best guess" chips? An EV (Electric Vehicle) is a car that runs solely on electricity that’s stored in an on-board battery that you charge up using a cable. I definitely recommend purchasing a kit that is complete. Subwoofers are heavy and have a lot of vibration when in use. They should be labeled and/or color-coded to make it more clear. LISTEN. A low-pass crossover is a feature that will filter out upper-range sounds and will allow you to play only clean sounding bass. It is a box of electronics which plugs into the ROM socket on the ECU, and a laptop or PC. You should prepare the ECU to get adapted only to the conditions that it would normally encounter. Shut off the engine. Although many are extremely compact to fit in space-limited vehicles, some like this one offer bass nearly as good a more expensive amp & speaker box. You can find 25 ft lengths or smaller for a good price. Atmel AT29C256). You should hear sound and the amplifier power light should indicate that it’s on. It will pretty much guarantee you’ll get good sound. The next series of 4 bytes, 43 FA 00 00, is a value of 500. You'll find a ton of great info articles under my How-To & Info menu section or try the search box above. Well thankfully there is and they are called piggy back ECU's or aftermarket ECU's. If you want real “thump” and heavy-hitting, loud bass, plan to spend more and get a model with more power. ECU resetting is over. Allow your ECU to relearn and perform. Fitting a turbo timer will also help with this problem and keeps the engine ticking over. A crimp tool (shown with crimp caps) is a great tool for a professional-quality installation to avoid having issues with wire connections later. The numbers in red represent RPM values, the green numbers represent Mass Air Flow and the numbers in the yellow matrix represent fuel injector pulse width. including a wonderful amp I reviewed here as well! Whenever possible, if buying a powered subwoofer, get the largest model you can fit into the space you have available. If you do not have a turbo there's very little to be gained by a remap alone - perhaps only a few BHP so TorqueCars' recommendation for non turbo cars is to modify everything else first (cams, pistons, increase compression, engine balance, air intake, exhaust, head work, bigger valves etc...) after these things have been done you can then consider a remap which will help you get the full benefit from them. Sometimes it’s referred to as a BEV (Battery Electric Vehicle) but is most commonly known as an electric car. Make sure you have a good, tight connection without any stray wires sticking out in a way that may lead to a short-circuit. You are responsible, if you program the system too lean and melt your engine, don't blame the system maker. Here’s a great list I’ve put together of some of the best affordable and well-performing models. 3. 14. In order to help you understand the big picture I’ll explain the basic things we need for great sound and a successful installation: In most vehicles, a +12V connection at the battery is relatively easy to find and route power wire to the amplifier mounting location you’ve chosen. There are some excellent choices available today including a wonderful amp I reviewed here as well! This did a sufficiently good job, but for the most effective power you would need to vary the timing to a greater degree than a fixed ratio advance curve. Other disadvantages of extra high FP: So, you probably need to upgrade the injector and possibly the fuel pump (if you push FP or run high CR or boost) and if you exceed 310 cc/min then you will need an ECU re-program. Pick one and change to 8000 and see if you hit the RPM limit. A useful trick is to use a coat hanger to make a “wire snake” to pull wire through tight and difficult areas, especially when going from the interior into the engine compartment. It’s the best bet for the beginner and the average person in my opinion. Most independent tests that I have seen on performance chips for naturally aspirated engines have indeed shown minimal or no gains in acceleration. It is also a fact that manufacturers use the remap to produce different power versions of the same engine and get lower insurance cover ratings and better fuel consumption. I’m a big fan of the Black & Decker cordless drills and they’ve done very well for me for installation jobs. After 5 years, you may have lost about 60% of its value! This can entail entering hundreds of points in most cases and you will require either a dyno or a long deserted road plus some indication of mixture strength to properly tune such a system. You’ll have more flexibility in the future and won’t have to buy another amplifier. An "off the shelf" or mail order ECU is a programmer's best guess at trying to make a program that will fit as many different engine combination of mods as possible...that's why I call these "one-size-fits-all". It's supposed to be one of your last modifications and not one of your first, to prevent the need for multiple chip reprogrammings after each addition of a new modification. Agencies & Freelancers . Some unscrupulous programmers will promise to sell you a "Mugen" like chip but in reality, all they have done is moved the redline higher and removed the CEL warnings. A bass boost typically works boosting bass response around a fixed or adjustable frequency near 50Hz for example. If by chance you find a plastic hole plug like this pop it out using a screwdriver and use it as a ready-made power cable hole. Then use the “coat hanger trick” to act as a wire snake for help pulling the wire through. Kick the oil habit now. Product Updates. However, the board mounting idea looks much better and means you can mount your amp out of the way in many cases. Connect to this if available. However if you are going to change the operating conditions on medium or long-term basis then you should reset your ECU. The electronic ignition system was born giving much finer control over fuel delivery and spark timing. Car powered subwoofers tend to be more oriented to solving the problem of limited space in a vehicle and may be more limited in their speaker size, amplifier power rating, and the bass volume they can produce. NVX XAPK4 True Spec 4 Gauge 100% Copper Single Amp Wiring Kit with Speaker Cable, No RCA.

Use wire cutters to cut off the extra remaining zip tie length. EEPROMs can be electrically erased and re-programmed, usually much quicker than EPROMs (e.g. 5/16″ ring terminals like those on the left are excellent and easier to use as well as being included in many good amp wiring kits. If you’re adding a subwoofer to a factory system you should definitely prepare for extra work. The main thing to remember is to buy quality wire – preferably a name brand type – with good insulation and good conductors. If you’re using a bridgeable amplifier connect the wires to the amp in a similar fashion as shown here. These are 28pin chips 1.5 inches by 0.6 inches. This is the only way to ensure that you get the best in both driving as well as handling. Many small subwoofer combos are ported to get more sound from a small size. Alpine CDE-HD149BT Single-Din Bluetooth Car Stereo with HD Radio, Premium LCD Display and... A good, solid connection to the car’s metal body, +12V “remote on” lead to turn the amplifier on or off with the stereo or ignition, An audio signal source (radio/head unit) for the amplifier, A speaker made for producing heavy bass (subwoofer), An enclosure designed for bass to install the subwoofer in (or a preassembled subwoofer box), An amplifier with a low-pass crossover feature and enough power to drive your subwoofer (150W RMS or above is recommended), Amplifier wiring kit (see notes below) with fuse holder, remote wire, and connection accessories, Speaker wire for the subwoofer (and signal connections if using factory stereo), Mounting brackets for mounting down the subwoofer box if needed, Cordless variable speed drill – not required but highly recommended, Good quality electrical tape (should say “UL Rated” on the inner roll), Wire (zip) ties, small bag – 6″ or 8″ are great but others work well, A small package of 3/8″ length #8 self-tapping screws (if you have a drill), Wire metal coat hanger (great for bending into a straight piece for pulling wire), 150W RMS power for the subwoofer available (either a single amp channel or 2 bridged channels), Low-pass crossover for passing only clean bass and no upper-range music, A mid to high-quality brand with good reviews, Flexible and great for multiple speaker systems, Can be used in 2, 4, and other channel modes (bridged), Popular, so often many reviews are available, High higher power available for subwoofer use, Often can be as compact as or smaller than multi-channel amps, Not flexible – useful only for subwoofers in most cases, Model choice and options tend to be more limited, Many are low-pass only, no full range possible, Utility knife with a retractable razor blade, Miniature flat head screwdriver or another similar tool to pry apart plastic trim panels and adjust the amplifier gain at the end, Digital multimeter (test meter) for measuring voltages, Cordless variable speed drill with clutch (absolutely FANTASTIC for speeding up work, drilling holes, and driving screws! The longer the injector pulse the more fuel gets injected into the rotor. The list goes on. Now air temperature, engine speed, engine load and even control over turbo/wastegate control & fuel delivery rates means that precise management of the engine ignition timing is possible and you can achieve the maximum power output throughout the rev range. Here's an excellent low-priced model I recommend from Amazon. (Always check the specifications to be sure of power available and the required speaker Ohms rating). The ECU has to operate on the newly acquired data as this new data reflects the true conditions post modification. If no RCA jacks are available or you have a factory car stereo, you’ll need to tap off of speaker wiring to get an audio signal source. Be careful. You can now use your car whenever you feel like.
