Ok I like to know if a chipped P28 ecu can be Tuned or only Having a Hondata can only be tuned?? Mine only has a Xenocron base map which works great for the price they do it for but I like to know if it can be tuned without having a Hondata or not...

 

You don't have a clue and driving around on a basemap is ill-advised.. Contact these people.

Yes it can be tuned with any program that uses a chip like eCtune or Neptune. Even Crome if you cannot find a tuner in your area that uses eCtune or Neptune
