I currently have a dyno tune stored on ecuflash and the tephra patch loaded. I've got a set of 1000cc injectors sitting here for an E85 and normal gas tune. If I install the injectors and change the scaling would I have to do anything with the octane or ignition maps? I don't have a wideband installed so I have to wait for the dynotune to safely change anything on the maps.

 

If your gas map is good right now and you are just trying to get the 1000s scaled to use the existing map you shouldnt need to make any changes to the fuel or timing maps.

If anything it would only be small changes to the fuel map.

Make sure your trims are within -4/+4% and the map thats on there will work just as good as it had before.

 

Thanks for the help.
