Dual-Flash PCM's

What is the OmniTuner DUAL-FLASH?
The OmniTuner DUAL-FLASH is a member of the OmniTuner line of products by Digital Inflection Corporation. This device allows you to install two separate flash chips in one Powertrain Control Module. Most GM Generation III applications are supported but when ordering specify which PCM you have so that the DUAL-FLASH has the proper flash chips installed. GM used both 512k and 1 megabyte flash chips in the GEN III PCMs.
The DUAL-FLASH replaces the flash chip that was installed by the factory with two separate OEM flash chips that individually appear to the PCM as a single flash chip when selected. Through the use of a switch of your choice you have the ability to select which one of these flash chips is used by the PCM. You have the ability to switch between flash chips only when the ignition is in the “off” position to prevent accidently switching between flash chips when the car is running.
Possible applications for the DUAL-FLASH include tuning a vehicle for multiple fuels, assuming this tuning is compliant with emission regulations. You can use ethanol based fuels when available and switch back to conventional fuels when desired. Additionally you might choose to tune one flash chip for fuel economy but leave the other flash chip stock. Any tune that you can flash to a stock PCM can be flashed to either one of the flash chips of a DUAL-FLASH enabled PCM.
