When preparing an ECU for S300 installation it is very easy to make mistakes. Lifted tracks and dry joints can be very difficult to spot. This tester takes out all the guesswork. Simply plug it in and all LEDs will light up when the pins have a good connection. If a LED is not on, then you have a soldering or wiring problem.

RomEditor4 is Windows based editing software for the s100 and s200 which allows you to change the ignition and fuel tables in the ECU, as well as many other important parameters. It is supplied with a Hondata USB-Serial cable for datalogging and replaces RomEditor 3. For more information click here.

As of Monday Nov 6th 2006 all S100s ship with boost. The new price for the S100 is $195. The socketing kit includes a flash EPROM for repeated programming, two high quality machine pin sockets - one for protection of the fragile EPROM legs, a latch and the necessary resistors.

Until the end of the year (Dec 31 2006) Hondata is offering a trade up program for all existing S100, S200 or staged system owners for just $445. For more details click here.

The Hondata reflash is now available for the K20Z3 06 Honda Civic Si. This reflash covers a number of add-on parts with gains of up to 29 hp in the mid range. Click here for more information.

The SEMA booth number is 24694

Hondata now offers the s300j, which will work in JDM ECUs such as the P08, P30 and P72.  This fits with the knock board and only requires minimal modification of the frame of the ECU.  Please do not call asking for further details, as this is exactly like the regular s300, it is just designed especially for the JDM cases and circuit boards.

Hondata announces two reflashes for the 06 S2000.

The first for a S2000 in stock configuration, and the second for an S2000 with Toda Header (displayed below)

The 06 TSX reflash is the perfect complement to the mechanical improvements Acura has for the 06 model year TSX. Reflash performance gains are better than for the 04/05 TSX.

Now available, Hondata announces the s300, a plug in module for OBDI ECUs which allows real time programming and datalogging.

Now available!  Price for the K-Pro and adapter harness will be $1145 (user supplied ECU). 

This uses a 2002-2004 RSX ECU and an adapter harness.  You will also need the Primary oxygen sensor from the 2002-2004 RSX.  We will be offering an 05 K-Pro bundle that the user provides an ECU and we then modify the Ecu and add the K-Pro and include an adapter harness.  This solution allows the speedo to work properly as well as all sensors.  This kit will also work on the manual transmission 03-04 Accord, but will not run the instrument cluster.

Hondata is proud to announce the release of the much anticipated TSX reflash with gains up to 29 hp and 26 ft/lbs of torque. Now available for the Auto transmission.

Not yet available for the 05 TSX and ECU numbers RBB-A03 and RBB-A55.

As of 3/1/05, all s200's will ship with the 3-Step option included at no additional charge.  For those who have systems purchased prior to this date, you can purchase this upgrade for $50.  more information

On a K-Series engine, if the stock spark plugs have been replaced, it is very important to ensure that the replacement spark plugs have an integral resistor. Non-resistor spark plugs cause a large amount of electrical interference which may effect vehicle electronics, including the ECU.  more information

Owners of the K-Series programmable ECU prior to serial #261 may wish to further insulate the programmable board.  more information...

The k100 is a circuit board that is installed in your ECU in a similar fashion to the K-Series programmable ECU (K-Pro), but at a much lower cost. It allows your Hondata dealer to install a custom flash program based off any of the programs supplied with the K-Pro or any program of their own design. A dealer can also custom tune, using their K-Pro, a map specifically tailored for the customers car. More info
