[Diy_efi] Interceptor/ECU progress

Mon Mar 12 03:59:06 UTC 2007

Derek,
One EFI newbie to another: You are right, these guys ARE beyond most of us, 
many work in the industry.  Be Cool.  They understand and try to help us 
newbies - as long as you are polite and do your homework.

Lurk and learn, see how it's done, be patient and pay attention, there are 
lots of other guys in this group doing simpler projects who will be able to 
help.

These advanced guys are actually designing and building NEW systems.  But 
there IS plenty of help here IF you approach it right.  Read the archives, 
see how it's done.  No fooling.

Ernie B.
