Description
The s300 is a plug in module to the OBD1 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.
Features
New features for Version 2:
8 analog inputs.(datalogging only)
1 digital input. (datalogging only)
Additional security to help identify and prevent theft
Datalogging memory doubled in size for up to 2 hours recording.
Non battery memory backup for greater reliability and longer life.
On board calibration storage.
Main features:
Fits inside the ECU
USB connection for speed and compatibility
SManager Windows based software for parameter & table editing, calibration uploading and datalogging.
Real-time updating of ECU parameters & tables.
Built in calibrations for common engine combinations
Built in datalogging to a laptop
On board datalogging memory (8 MB memory, 20-240 minutes datalogging) with trigger conditions.
Adjustment for different sized injectors, with overall fuel trim.
Configurable for any MAP sensor (to at 5 Bar and above)
TPS based table lookup for ITBs
Engine protection from over boost.
Expanded fuel and ignition tables, both in rpm and load, to 60 lbs boost and 11,000 rpm (these are not the upper limits)
Launch control with anti-lag
Full throttle shift
Three multi purpose outputs for nitrous control or similar
Supports lambda tracing from a wideband o2 (PLX wideband recommended)
PWM output for boost control with fixed or gear based boost.
Dual tables for high/low octane calibrations etc.
Two analog inputs for wideband, EGTs etc.
High and low speed 24 x 20 ignition and fuel tables for correct VTEC tuning
Injector size fuel trim
Fuel trim for starting, throttle tip in and individual cylinder trim
Rev limiter with fuel cut or fuel and ignition cut
Launch control with anti-lag
Full throttle shift
Adjustable VTEC window with load and throttle control
Secondary intake runner control
Adjustable idle speed
Adjustable boost cut with hot and cold settings
Shift light
Closed loop control
Air temperature compensation
Water temperature compensation
Fuel and ignition correction based on gear
A/C shutoff conditions
Closed loop
Three general purpose outputs for nitrous control, quad boost control or similar
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.
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.
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.
ECU Preparation
Details
on preparing the ECU can be found here. 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).
Why buy the s300 over the competition?
Hondata has been the market leader in Honda ECU re-programming for over
a dozen years, and is the innovator in the market. We are the only
company to offer comprehensive support (email, phone and forum) for
products we sell, and have a full time, professional development team.
This means quicker response to support questions and higher quality
software. We also are the only true company operating in the market - we
are no going to suddenly stop development and support of out products,
leaving our customers with a worthless investment.
Hardware. The
s300 is the only hardware specifically designed for a Honda ECU. This
means the s300 fits straight into the ECU without any jumper wires or
adapters and the USB cable plug is accessible without needing to remove
the ECU lid. The s300 is also more securely fastened with multiple
support posts.
More hardware. The s300 has analog inputs which
are useable without surface mount soldering skills. It also is the only
product using the latest battery-less non-volatile emulation
technology, and anti-theft features built right into the hardware.
Software. Our software is the easiest to use and has the greatest
number of features to help you tune your vehicle. Many tuners charge
less to customers who use our software because it is quicker and easier
to use than any other software.
