Steve- yes, sort of... and I am cheating.  I am working on sequential 
staged EFI to drown a turbo converted motor (85 VW golf with CIS 
[K-Jetronic]) has 9 injectors, 4 CIS, 1 cold start and four solenoid/efi 
injectors)  I am using a hall signal driven off the cam pulley for phase 
and dividing time intervals to approximate sequential.  It will lag on 
accel and decel, but the phase should be close enough at high rpm to work 
(I hope!).  I am not programming, my professor is, I am learning C (just 
bought a book).  I am building the hall pickup and the injector driver 
board, using a Motorola MXP 4250 AP pressure sensor.  Using a pressure/ 
rpm map to drown the motor when it goes into boost.  Might run Methanol 
to evaporatively charge cool.  I hope to at least try it on the dyno.

PS, any opinions on metroworks "CodeWarrior"  or pro version for C 
programming and compiling?  THe "lite" version came with my book.  I need 
something that is mac 68k compatible.  And i have to get a compiler for 
the 68hc11.  Right now using the school's Introl.

Any input for C programming (on a mac) would be appreciated privately by 
personal e-mail

Thanks
