Can a CalVin ECU be reflashed?

[John Ulrich]

A friend has a CalVin.  When he puts a V11 Sport ECU on it it runs great.  Can he "reflash" his existing CalVin ECU or does he need to find another V11 Sport ECU. 
Thanks in advance.

Yes it can be reflashed

Yes. I ran a V11 sport (Scura) ECU in mine for 5K miles.  Transformed the bike.  With the one exception- it would ping under load when hammering the throttle.  It was a timing issue, Calvins are dual plugged V11 Sports are not.  Todd @ GuzziTech reflashed my stock ECU with a similar map.  All was well, and continues to be with its new owner.

Yes. Read and save the original map.

Be warned that it goes from a single plug timing profile on a twin plug.

 Calvin 2007 has done something sneaky with his ECU , he will weigh in shortly .

I don't think 15m maps can fit on 15RC at least when I tried. 

Better to get another 15M.

I kept getting error about the size of the map but I forget if it was 15RC to 15M or vice-versa.

John,

PM me your email address and I will send you a V11 sport map with a modified ignition curve for less pinging. I am still working on it so further mods will happen. Still the map makes a world of difference.
