    78 cuttlass, 403, 4l60

    I want to change to 4l60e trans & fuel injection. I have a 16197427 ecm & wiring, is there a way to get sequential injection from this ecm?

    Sequential fuel injection is possible if you fabricate a cam position and crank position sensor system for the Olds 403 so you can use a 1999 - 02 LS1 computer.

    Multipoint Fuel Injection like the 1986 - 92 TPI engines use is possible, see post #6 http://www.gearhead-efi.com/Fuel-Inj...Information-0D
