Hondata has been considered the benchmark for Honda engine management for years. Their newly released Version 3 S300 of the famed S series plug-in modules is the latest and greatest in tuning solutions for the Honda B, D, F and H Series engine. Naturally, we decided to test it out on our B18C1-powered project time attack Civic. The S300 module was installed in a P28 ECU (you can use any OBD-I Honda ECU), the ECU plugged back into the car, and we were ready to go—no wiring necessary as the car was already setup to operate with an OBD-I ECU (had it not have been, a simple jumper harness is all that is necessary to convert from OBD-II to OBD-I). We strapped the car to the dyno during a late-night tune, prior to our scheduled track event with Kristina Wong of SP Engineering fine-tuning the system.

The new Hondata V3 now allows for the use of a Bluetooth connection to monitor, data log and even tune the system without physically plugging into the ECU, we chose to initialize the S Manager tuning software by physically connecting the computer to the ECU via the included USB cable, within minutes a base map was loaded and tuning was underway. The straightforward yet comprehensive software allows for full adjustment of virtually every aspect of the computer, one of the great features that we immediately noticed was the ability to make changes on the fly while the engine is running—applying the new values in fractions of a second, saving precious time (most tuners charge by the hour) by omitting the need to make modifications and reload the map. Once the tuning was completed we managed to not only increase peak power output but also showed significant gains throughout the entire powerband as well as a flat, more usable midrange. As exciting as it can be to see numbers, we wanted to see how the car performed at the track where the S300 would really be put to the test. Willow Springs International Raceway's Streets of Willow was the chosen venue for this test, due to its large variety of corners and abrupt elevation changes. On the way to the track we had a chance to check out the Hondata Mobile smartphone application by utilizing the Bluetooth capability of the module. Hondata developed an application that can be used to display every reading that the ECU processes on your iPhone or android screen and can even calculate mpg—a very neat and useful feature. Hondata S300 Base Maps Download 2017Testing took place over two days, as we had the opportunity to drive the car in very different conditions back to back. The first day was windy and cold, while the second day was hot and dry. The S300 performed as we had expected—flawlessly. We encountered not a single hiccup in the two straight days of testing. As a matter of fact, the laptop stayed in its bag the entire weekend; all necessary compensation due to the temperature and altitude differences occurred perfectly and seamlessly. Overall, the S300 allowed us to squeeze an additional 7.9 peak horsepower from the car and 3 hp on average, gains that will be significantly higher on a more extensively modified engines, especially with forced-induction applications. The most important and beneficial aspect of the Hondata S300, however, is the reliability of the unit, in which we are confident to run our engine all day long in any temperature or track conditions.

310-782-8278 http://www.hondata.com Hondata S300 Base Maps Download For MacThe 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.Note that there is a rectangular frame ECU version of the s300 and a square frame ECU version (JDM). Main features: * Fits inside the ECU * Made in USA * Built on the proven s100/s200 code base * USB connection for speed and compatibility * SManager Windows based software for parameter & table editing, calibration uploading and datalogging. * Real-time updating of ECU * Built in calibrations for common engine combinations * Built in datalogging to a laptop * On board datalogging memory (2 MB memory, 20-60 minutes datalogging) * 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 * Dual tables for high/low octane calibrations etc. * Two analog inputs for wideband, EGTs etc. SManager editing software features: * 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 * MAP sensor type and calibration * 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 * On board datalogging trigger conditions 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. 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.
