[Diy_efi] Interceptor/ECU progress

[Ernest Buckler]

Adam,
Absolutely!  And I know more than a few CXTC owners who would be right in 
there with me, am in regular touch with the fellow who ran a CXTC 
aftermarket shop for many years.

Not sure I know what you mean about "closed loop spark timing" tho, thought 
that had only to do with mixture?  Tho can see why constantly variable 
timing would be key to success when going for ultimate performance out of 
these motors.

I've got your book on my table to start reading again, now that I have more 
questions and am slowly getting a feel for the possibilities.

Also have Yam Venture Royale project that REALLY needs EFI, tho non-turbo to 
start with; carbs are big and sophisticated but per typical Yam parts 
pricing, one rebuild would pay for half of a MegaSquirt, or?  Definitely 
looking for ideas & suggestions on that one.

Thanks!
Ernest B.
