Simply put, Crome is an OBD1 Honda ROM Editor which lets you edit and add extra features to your stock ECU. This gives the ability for one to run a Honda B/D/H series engine with forced induction systems (ie. turbo, supercharger) or individual throttle bodies.
Breakdown of Application Parts
Crome broken down into three main parts which work together to bring about a very capable and versitile application. These three parts are: the Core, the Plugins Manager, and the Tuner.
The Core
The core Crome application is the main GUI which handles editing of ROMs. Technically, Crome will run with just the main executable and edit stock Honda OBD1 ROMs, but this is very limitting since it does not allow for one to add extra features to the ROM such as boost support, or launch controllers. This is where the idea of plugins come to work.
The Plugin Manager
The plugin manager allows for additional modules to be incorporated into the Crome core application through the use of javascripts. Each module is called a plugin and is capable of adding extra features to a ROM as well as providing instructions for the application on how to handle the extra features.
The Tuner
The tuner module gives Crome datalogging and tuning capabilities and is available only with a Crome Pro or Dealer license.
On a scale from 1-10 with 10 being the highest I would have to rank the basic Crome program at about a 6 with Crome Pro at a number 8 as it carrys more features. All in all its one of the best values out there for the DIY tuner needing to tune OBD0 and OBD1 Honda setups.
