Must the ecm have the stock flash to begin using the FP3 or will it work with a ecm that has a stage 1 flash?

 

Good question. I'm curious to know myself. I would assume it would still work though. It may just save your present map to reinstall later.

 

I would find out before you plug it into the bike and do anything because the FP3 marries to your vin # and you'll never be able to use it on another bike now return it once you take the plastic off the box it comes in

 

It will save whatever map that is already installed, and will flash the new map from Vance and Hines, then auto tune new map if you want to, yes it will work

 

Personally, I would have your dealer flash your bike back to stock.

You would would want the FP3 to have the stock settings to work off of and store into the memory, and there would be no chance of conflict between the two flashes.

 

^^This.
Don't worry about dealer flash. It will have no impact using the flash from FP3.

 

Other than going to the dealer is there any other way to find out if the ecm is has a stock flash?

 

Did the dealer do the stage 1 flash and how did they do it?

 

No I'm just curious, I know that some tuners will only work from a stock tune.

 

I started with the Stage I dealer flash. Installed the FP3, it created the baseline flash and I've reflashed it a couple of times. No worries.
