95 LT1 PCM (16188051) uses a 16202476 MCU !!

[R. W. Hughes]

Once again I sent this to the wrong list, got to get organized.
               
According to what little information I have, there exists a SFI66U used
on LHO 3.1L(Vin T), L82 3100 GenIII(Vin M), L32 3.4L (Vin S), and
presumably others since then (early 90's). SFI means sequential, 66
means two GMP6 processors, and U means underhood mounting. To quote:

>The dual processor consists of an "A" side and a "B" side. The "A" side >controls spark, fuel,
24x and 3x signals, fuel pump, EGR, and EVAP. The >"B" side controls
IAC, fan(s), A/C, and the
transmission.

This information came from the "60d V-6 Powertrain Enhancement Manual"
published by Service Tecnology Group of GM dated 4-94
