PRODUCT DETAILS
Hondata S300, Tuning Solution for B D H F Series Engines
The Hondata S300 Version 3 is a plug in module that turns your stock OBD1 Honda ECU into something you can actually tune. You supply the manual transmission OBD1 ECU, the S300 drops in and you get real control over fuel, ignition, boost setups, safety limits, and more without ditching the factory computer. We run these exact units on our own cars because they just work when you need repeatable results. Hondata designed, manufactured, and assembled the S300 in the USA.
If you want to buy Hondata S300 because you are done guessing with chipped ECUs, this is the clean way to do it. The Hondata S300 software is SManager, and it covers Hondata S300 tuning plus Hondata S300 datalogging in one place. Note for the USA, Hondata S300 for racing only. This is legal only for racing vehicles that may never be used on a public highway.
Key Features:
- Ethanol content sensor support, so your Hondata S300 engine calibration can follow real ethanol percentage instead of your best guess
- Hondata S300 Bluetooth support for laptop programming and datalogging, plus mobile datalogging
- 2 to 4 times faster datalogging
- CAN output
- Serial output for dashboards like AiM MXL and Racepak IQ3
Hondata S300 real-time Update
The Hondata S300 real-time feature lets you upload changes with the engine running, without upsetting how the car runs. A full calibration takes about 2 seconds, and small changes happen in a fraction of a second. You change something in SManager, it goes straight to the Hondata S300 ECU, and you see it immediately. The S300 does not use an EEPROM style chip, so you do not open the ECU, swap chips, or burn ROMs. You just need a laptop with USB, or Bluetooth radio capability.
Hondata S300 datalogging
Hondata S300 datalogging is built into SManager over USB or Bluetooth. You log sensors, graph them, save runs, and actually figure out why the car did what it did. The S300 also has on board flash memory, so you can record without a laptop and download later. You can store multiple logs for around 120 minutes total. Start and stop recording with an external switch, or let the ECU trigger it by conditions. Example, set it to start logging when you bring rpm up near launch, then stop after the traps when rpm drops below your threshold. It is the kind of detail that makes the Hondata S300 for racing so useful.
*Please note all S300 sold by Hybrid Racing are for USDM ECUs, which are rectangular, not square.
**All Hondata S300 sales are final once the product has been received. Because tuning devices and licensing get messy fast, Hybrid Racing does not accept returns on used or potentially used units. Confirm fitment and intended use before you place your Hondata S300 purchase, and contact us if you are not sure. SKU: HON-S300
