Questions & Answers

Is there a page/note outlining that older firmware is required for succesful connection?

I've noticed many older vehicles actually require older versions flashed on the EVO.

Hi, in most cases once the EVO is connected to the Flashlink Manager software and the vehicle fields are populated, the correct firmware will pop up.

The J1850 data bus found on older GM and Chrysler vehicles was removed from firmware above 4.06. So the preloaded 4.18 would not work on any of those vehicles.

 

In the latest vehicle specific firmwares, we started re-introdicing the J1850 databus. We still recommend using 4.06 because technically, we cannot physically test the J1850 compatibility of the NEWEST firmwares on older vehicles. Latest firmwares (which may say (BETA)) are supposed to work if the description of the firmware says "Added J1850"..
