According to my testing and understanding - there's not a great reason to move to V4 from V3.  The performance did not seem much enhanced with the two I played with - but I didn't give it much thorough testing. 

It seems even the manufacturer really just did it because they could get the new main IC cheaper. 

**Note:  Purchase of supplies from my shop does not entitle you to me personally supporting your install.  I'll try to help out with questions or issues as much as I can, but my personal support of your install is not guaranteed.  If you need help, check out for some guidance on the type of info I need and then use the "contact" page to reach out to me.


This product requires professional installation and should NOT be attempted by amateurs.

Due to the high possibility of user error the Ace V chip is sold here with absolutely NO WARRANTY.

There are NO RETURNS ACCEPTED under ANY circumstances once the item has been touched by a soldering  iron.
