727 ECU limits

[ECMnut at aol.com]

Hi Dave,
 I was considering doing this on one of my brother's many 4 cyl bikes.
 Since the MPFI fires the injectors twice per intake event, I'd set the
cyl select to 8cyl and end up with one inj-pulse per intake event
and the ability to see 12k RPM with the 4cyl Kaw engine.
This does not address the ignition.  I was going to manage fuel only,
and tap into the factory primary coil wire(s) and use a transistor arrangement
to simulate a dissy pulse for timing the injection.  
 Since every inch of the turbo code has been exploited, I was 
going to use a 7749.  TK has a gmepro for the turbo 7727 app
if you want to use a weather resistent box.  Sorry I wasn't more help.
