The computer is connected via three connectors that pull out when a plastic clip is pressed. Remove the computer, and with a philips screwdriver remove the metal lid from the top of the computer.
There may be small daughter circuit board covering some of the main circuitry. Unscrew this and lift it out of the way. Honda ECUs run in generations, which use different connectors. Below is a stack of ECUs running from the newest generation at the top to the oldest generation at the bottom. The middle three characters are the most useful to identify what the ECU is. Different generation ECUs may use the same characters.
Here is a list of common ECUs:. The last 3 characters are broken down into 3 parts. There are other versions of this, but you get the idea. The second digit "0" typically means manual transmission, where a "5" means automatic transmission, and the last digit "1" is the version number. This is usually a two or three digit number stamped on the 28 pin ROM, or main processor.
Accord and Prelude ECUs can use a letter and number code.All of our systems come with our easy-to-use MTune software for advanced or simple tuning.

Technical Information ECU Identification
It is possible to damage the vehicle's electronic control modules during the reprogramming process. Once the reprogramming process has started, the process must NOT be interrupted until the process is complete. If you experience any problems, contact your toolmaker or supplier. It connects to any Windows or later PC with an Internet connection.
Units are tested to ensure performance standards are met. Units and cables may have minor scratches and nicks, but operation is not affected. The currently offered HIM tool covers all reprogrammable vehicles thru Note: The current HIM tool will not work on some models, and a new generation interface module tool will be required.
This tool will be available late Software updates Both new and refurbished units include the first year of PC software and control Module calibration updates and technical support. To continue to receive automatic updates and technical support after the first year, you must enroll in the software subscription program. Once enrolled, instructions for downloading the software updates will be sent via e-mail.
You will be notified of subsequent software updates throughout the remainder of your enrollment. This unit connects to any Windows or later PC with an Internet connection. NOTE: You must be a current Service Express subscriber to order the tool, to subscribe to the software updates, and to get access to the latest documentation on the use of the tool. Hardware and software requirements: Windows or later PC with Internet connection RS port required to connect PC to HIM Active subscription to Service Express At minimum, a 3-day subscription is required to rent the Smart Cable tool, subscribe to software updates, and to get access to the latest documentation.
We recommend that you periodically update your subscription to check for the latest related bulletins, newsletters, and service manual procedures. You may purchase or rent the HIM tool, but in either case, you will need an authorization code specific to the Control Module you are replacing. Upon receipt of your rental request, Helm will put a reserve on your credit card for the full value of the rental tool HIM and software.
Honda/Acura Diagnostic Software (HDS) with Modular Vehicle Communications Interface (MVCI)
If your shop already has a HIM tool, you will not be charged a rental fee. There is no charge for the PCM initialization software and code. Requests received by AM ET will be shipped the same day.Among the many things we love about Honda is its emphasis on advancing technology, whether that encompasses variable cam timing, producing zero-emissions engines or building robots to help old folks live better lives we get the shivers when we hear rumors of Honda contemplating entry into NASCAR.
This exploratory spirit has filtered down to Honda heads populating the Internet and given rise to one of the most exciting grassroots tuning movements around: DIY engine control. This ain't just dialing in cam gears. This is real car geek shit: laptops, chips, burners, code. Be warned: the following report from our own in-house car geek is not for newbies. It assumes a certain familiarity with engine management principles.
That doesn't mean beginners should shy away. There's a wealth of information out there, happily shared by the enthusiasts who've already taken a machete to the cluttered path. As one pioneer of the movement advises, get some strong coffee and a blank notepad with a lot of pages.
Once you dig in, you'll find it hard to stop. Every Internet community starts with a visionary and some server space. The forum's humble beginnings were at a "borrowed" domain name pgmfi.
Currently, the forum boasts more than 3, registered members, all working toward the same goal:. The majority of the site's members probably don't know Blundar's girlfriend.
Blundar isn't even referring to his girlfriend, more the idea that programmable engine management software and techniques should be easy enough for all to understand.
Blundar says, "My girlfriend is very smart, but she is not all that mechanically or scientifically inclined. The first goal the group set for itself was to document the Honda ECU by disassembling it byte by byte. Developing a replacement for the stock program, commonly called "chipping," came next. The ECU requires no major modifications, just a few additional components soldered into pre-marked locations on the board. Although enthusiasts succeeded in unlocking and modifying an ECU, its lack of a visual interface made tuning less than user-friendly.
Over the past two years, TurboEDIT has progressed into an unrivaled OBD-0 tuning platform with a host of advanced features including 3-D fuel and ignition maps, datalogging, real time programming and map scalar editing.
Eventually, I decided to set out and write something myself.What software can we use with this hardware to tune these vehicles with?
First, what vehicles are we able to tune with factory ECUs? The shear amount of options here is what leads us to these tuning solutions. As you can see, this entire list is most of the Honda and Acura automobiles that are on the road today being tuned in a variety of ways.
Because you can basically cover the entire gamut of makes and models with one ECU…this makes your ability as an engine management tuner much easier.
Shown in the image below are the ecu connector recepticals for identifying Honda ecus. You only need three to four main pieces of hardware to tune these vehicles and ECUs.
Of course you need a properly operating vehicle and a chipped ECU for your specific application to start. Hondata came out first with the S unit which fits inside of the ECU case and is connected via one single USB cable to a laptop computer. See our other write-ups for more specific applications. I hope this article helps shed some light on why Honda vehicles are so easily tuned and the variety and that the possibilities of different parts combinations and tuning variety are endless.
