EFI control units

[Michael D. Porter]

I'm very new here--just been reading this group for a couple of 
weeks--and have a question or two on available control units.  I've been 
sorting out what I think I need to convert Triumph six-cylinder to 
digital FI, but have not yet found a control unit which seems to meet the 
requirements I've set.  

I'd like to find a controller with sequential injection and is also 
programmable via laptop and can accept input from a domestic MAF sensor. 

I realize many of the folks here are concerned with building their own 
control units and doing much or all of their own programming, but I 
simply don't have the time or test equipment for that sort of 
undertaking.  

Any suggestions?
Thanks.
