Im running ECU Flash 1.29a (because I have the older cable), and it seems I can only seem to read/write to my ECU if my engine is running, it will shut it off and most of the time it works, if I just try it with Engine Off, Ignition on it almost never works, it will attempt to send the 3 codes and it just times out and gives me an error...

Has anyone had this issue before?

thanks

 

battery...

u need to have it fully charged.

also you can contact tactrix/evoscan for an update to the cable to allow it to work with newer ecuflash version

 

Is that all it is? Battery voltage? Ill put a battery maintainer on it tomorrow and see if it works with that.

Thanks for the quick reply.

 

+1. To the OP, is this a mini battery or just an old IX OEM battery? Those two situations seem to exacerbate it more on the IXs.

 

oem IX battery

is there a certain voltage ECUflash has to see before it will continue on with reading/writing to the ECU?
