** As of 2/8/12 all of our S300 units are now the S300 version 2. **"The s300 is a plug in module to the factory Honda Engine Computer (ECU) which vastly expands the capabilities of the factory ECU. Forced induction, datalogging, real time updating of parameters, engine protection are but a few of the s300 features."
We are proud to offer Hondata's top of the line tuning products like the Hondata S300 to our valued customers. The S300 is by far one of the most advanced Honda / Acura tuning systems on the market. It offers superior tunability with forced induction support, datalogging, boost control capabilities, and so much more. Below is a brief summary from Hondata. If you have more questions on whether or not this system is right for you, please don't hesitate to contact us
Each Hondata S300 system sold by us at HA Motorsports has it's own unique serial number from Hondata. This not only verifies it's authenticity, but is extremely useful for recovering your Hondata unit in the event of theft.
* Sold as a complete system including USB cable, S300 software, installation kit, and Hondata decals.

NOTE: The s300 uses different connecting pins in the ECU from the s100/s200, and also has a slot cut in the side for the USB connector, so the ECU must be modified for use with the s300. The s300 is made to fit in a full frame ECU case (US and most markets), so will not fit in a JDM ECU case.USB Connection:
The s300 uses a high speed USB connection for both programming calibrations and datalogging. No more USB/serial connectors!Real-time Update:
The s300 can be updated in real-time with the engine running without affecting the operation of the vehicle. This means that calibrations and changes can be uploaded to the ECU very quickly (2 seconds for a new calibration, a fraction of a second for anything else), without interrupting the operation of the engine. Changes made in the SManager software are uploaded to the ECU instantly and you can see the effect immediately. The s300 does not use an EEPROM or equivalent, so you never need to open the ECU to change chips nor 'burn' ROMs. No EPROM programmer is necessary - you just need a laptop with USB port.
Note that this the only true real-time update available for Honda ECUs. Any portion of the ECU (including the whole ROM) may be quickly updated with the engine running, without the engine stalling or going into limp mode.Datalogging:
The s300 has datalogging to the SManager software built in via the USB port. Using a laptop the various ECU sensors can be datalogged, viewed, graphed and saved for later analysis.
Additionally the s300 has on board flash memory which allows a datalog recordings to be made without a laptop, for later access and download to a laptop. Multiple recordings can be made and stored in the s300 for a total of around 40 minutes of total datalogging time. An external switch can be used to start and stop recordings, or engine conditions can trigger recording. For instance in a drag race, the s300 can be set to start recording once the rpm is bought up to near launch rpm and automatically stop once past the traps and the rpm drops below a certain level.MAP Sensor Compatibility:
Any linear MAP sensor can be used, using a scalar and offset to translate the MAP sensor characteristics into pressure. Popular MAP sensor settings are built in for ease of setup. To do this you will need the map sensor calibration numbers from the manufacturer of the sensor. For a trouble free installation, please take a look at the Hondata 4 bar map sensor.ECU Preparation:
It is strongly recommended that you have this professionally installed as this is more difficult to install than an s200 and if the ECU has been previously socketed you run an even higher risk of damaging the ECU (lifting tracks and or burning them).Note: We offer Hondata S300 unit installation into customer provided ECU's.
