HONDATA S300 V3 (USDM ECU) - HONDA / ACURA

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 or Radio technology capability.

Datalogging

The s300 has datalogging to the SManager software built in via the USB or Radio technology. Using a laptop or mobile device the various ECU sensors can be data-logged, viewed, graphed and saved for later analysis. 

Additionally the s300 has on board flash memory which allows a datalog to be made without a laptop, for later access and download.  Multiple recordings can be made and stored in the s300 for a total of around 120 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.

S300V3 UNIT WILL COME BY ITSELF AND NEED TO BE INSTALLED IN AN ECU YOU PROVIDE, UNLESS YOU SELECT THE OPTION TO PURCHASE THE ECU LISTED WITH THE S300V3 INSTALLED; HERE YOU WILL GET A COMPLETE READY TO PLUG IN ECU WITH THE PROGRAMMER.  PLEASE ALLOW UP TO 48 HOURS MINIMUM FOR A TECHNICIAN TO COMPLETE WORK AND YOUR ITEM TO BE PREPARED FOR SHIPPING.  ECU AVAILABILITY IS NOT GUARANTEED AND IS ALWAYS BASED ON CORE STOCK AT THE WAREHOUSE.  PLEASE INCLUDE IN NOTES WHICH TYPE OF ECU YOU WOULD LIKE AND IF YOU NEED AUTO OR MANUAL.

Came based on a work buddies recommendation. I was late by 30 minutes, confused my appointment time. But, 10/10 would come back. Came for a Downpipe and midpipe install. Not only was the gentleman accommodating, He ran into some issues, staff helped me out and pointed me into the right direction and got me going! They got my business and wouldn’t go anywhere else again!
