PLEASE NOTE: THIS DEVICE WORKS WITH FORSCAN ONLY!
If you require other software please order our ELM327 with manual switch.

This modified ELM327 is designed to work with Forscan for Windows auto MS mode.

The device will automatically switch from HS to MS when required and without any user input.

This makes the device much faster and easier to use. 

The ELM327 has the same reliable chipset as our popular USB switched type.

IMPORTANT: Please read these setup notes:

Before use you must click the Forscan settings icon, and on the connection tab change the MS-CAN SUPPORT setting to RTS Relay.
Failing to do this will not allow the product to switch between HS and MS.

This product is the same as our Modified ELM327 but instead of a manual switch, the process is automatic.
This unfortunately makes it only suitable for use with the Windows version of Forscan and currently does not work with any other software or non Ford/Mazda vehiles.
Please consider this carefully before purchase. 

We do not provide software. Please see our links page.

USB ELM327 and software is for Windows PC only. It can be used with iMac but only if running Windows via dual boot or virtual machine. 

USB ELM327 cannot be used with iOS or Android devices. Please see our WiFi ELM327.
