Hondata S200 Rom Editor Pc
Romeditor was discontinued in 2005. Information for reference only.
I just need the FULL working version of Hondata Rom Editor V3. I hit the Hondata forums and talked to a guy on AIM that said he worked for Hondata and he was arguing with me telling me. Hondata s200 Review User Name. It answers almost all questions about the Hondata reflash and the Hondata K-Pro. Demo of the Hondata s200 ROM Editor.
- I just need the FULL working version of Hondata Rom Editor V3. On AIM that said he worked for Hondata and he was arguing with me telling me PR4's couldn't run VTEC yet I have it done S200 Program. My question to him was getting it hooked up to my computer, I told him I remembered some what big blue boxes coming with the ECU's in the.

However, using the s200 is fairly similar to using the new K-Series ECU Manager software, and a lot of the principles and settings discussed by Doug apply to the K-Series as well.
ROM Editor is Windows based editing software for the s200 which allows you to change the ignition and fuel tables in the ECU, as well as several other important parameters. You need an EPROM programmer (like the Pocket Programmer) to burn EPROMs for the ECU.
Custom Tunes
More custom tunes have been built into ROM Editor, saving you time when tuning a new vehicle.
Improved Base Fuel Maps
When creating new ROMs it is possible to adjust the part throttle portion of the fuel tables to suit larger injectors (the changes detailed on injector sizing have been incorporated). This reduces part throttle tuning time.
Program EEPROMs from ROM Editor
Under Windows NT, 2000 and XP it is now possible to burn the Atmel 29C256 EEPROM from within ROM Editor. Select 'Burn EPROM' from the file menu. A very convenient feature which will save you lots of time. Air conditioning cutoff (s200 only)Shut the air conditioning compressor off automatically for increased performance when you need it.
Extended RPM Tables (s200 only)
Fuel and ignition tables are tunable to 11,000 rpm on all supported OBDI ECUs. This allows more precise control of fuel and ignition at high rpm. Improved VTEC Options (s200 only)
- VTEC switching has been changed to switch based on engine speed and engine load.
- VTEC can be disabled entirely for non-VTEC engines
- The VTEC pressure input can be disabled for JDM Type R engines.
- By disabling the VTEC spool the ECU can be configured to extend the fuel and ignition tables to 11,000 rpm for non-VTEC engines.
Japanese P08 ECU supported. More sensors can be disabled. This is useful for Asian ECUs, or for race cars with sensors missing. You can save a description, comments or tuning notes in the ROM file.

Tuning the ECUChanges made to the fuel & ignition tables, or other settings, can be saved to a file and written to an EPROM using an EPROM programmer. ROM Editor will interface to two EPROM emulators, allowing the ECU to be updated very quickly. With the RaceLogic emulator changes can be made in real-time while the car is running on the dyno. ROM Editor can datalog from the interface box. This is useful while tuning so that the position of the tables which is being used can be viewed in real-time. Here is a quicktime movie (550 kb) which shows ROM Editor during a dyno run. The car is run through the gears before the dyno run so that the engine is at the same temperature for each dyno run. The red spot is the position in the table which is being accessed by the ECU. With a wide band lambda meter and Emulator it is possible to use RomEditor to Autotune the fuel tables. The fuel tables can be scaled with an injector multiplier (fuel trim) for different sized injectors, fuel pressures or even engine capacity changes. The picture shows the how you could recalibrate a stock P28 Civic EX computer with higher fuel pressure and bigger injectors to drive a turbo H22A Prelude. This gives you huge flexibility in recalibrating OBD I ECUs for a variety of engines in a variety of tunes. Managing your fueling this way allows you to remove inaccurate devices like rising rate regulators which also can place the stock injectors under extremely high fuel pressure and reduce their life. Throttle tip in and cranking enrichment can be altered to suit your injectors and engine. Requirements
Hondata S200 Rom Editor
- Hondata s200 and Datalogging.
- Windows 95, 98, ME, 2000, NT or XP.
- Pentium 133 with 32 MB minimum.
- Pentium 400 with 64 MB recommended.
- Keyspan USB-serial adapter for newer laptops without a serial port.
This is an advanced feature that allows your laptop to record the path your ECU takes through the maps. Once recorded you can replay your dyno or road run and see exactly which fuel and ignition value your ECU was using at every RPM and load position. By replacing the stock oxygen sensor with a wide band Lambda meter such as the PLX, you can record a very accurate air/fuel ratio in real time. This makes it very fast and very accurate to tune your engine to a specific air/fuel ratio without using a dyno.Changing MAP sensorsUpdating ROM VersionsTo update the rom version from either a 2.5 version ROM or from an older version 3 rom to a newer versio do the following:
- Open the file in Romeditor
- Click on FILE
- Click on Convert ROM Version
- Select what you are going to convert to (v3 ROM's being updated to latest version just reselect the correct ECU)
- Click Ok
- Save the file
Fuel & Ignition tables
The Honda ECU has two ignition and two fuel tables, so that there are separate tables for the low and high speed cams. Each table is divided into rows and columns, with engine revs being indexed by row and engine load indexed by column. Hondata expands the factory table size to allow additional columns for boost. Typically the factory 20 x 10 tables are expanded to 20 x 16 cells for the low cam and 24 by 16 cells. This provides 704 tuning positions, more than most replacement ECUs. Pictured is a 3d representation of a low speed cam ignition table. Visualizing the table in 3d helps you pick any incorrectly entered data and to understand trends. The blue area selected with the mouse can be increased or decreased in value 1/4 of a degree at a time. This accuracy of timing is needed for maximum boosted and naturally aspirated power.

The stock MAP sensor can see boost up to 11 lbs. For higher boost levels a 3 bar MAP sensor can be used. The only change you need to make in ROM Editor is to check the '3 bar MAP sensor' box.
