Will Creedon is THE AUTHORITY on the chips for these early 4V bikes (Daytona, V10-Centauro). He developed the best ones that went all over the world.
He is contactable via the Centauro Owners Group. Do a member search and send him a message.
He still sells his “C5” chip and if anybody knows what you have from those markings, he will.
I am from San Diego and know Will personally. He’s a great guy. Old like me now.
I have his C5 chip in my V10-Centauro.
PM sent, thanks form another old guy
I do want to clarify that there are indeed, others who did not like Will’s chip. It’s a matter of taste and opinion.
For my Centauro, it worked well but there were those with 1100 Sports that had potential problems due to the rich furl settings Will tended to use.
These chips were all back in the early years and all seat-of-the-pants designs. Nobody had sophisticated dynos at motorcycle shops back then except New York Mike at San Diego Harley.
Will’s stuff certainly was not dyno developed and dyno tested like my full setup from Todd on my Stelvio NTX.
I offer the information and as a direction for you to follow perhaps, and not as a perfect solution.
