1979 Cadillac Seville EFI

This is an install for a friend, the purpose is/was to replace a faulty standard EFI computer with the simplest Megasquirt install available.

Car: 1979 Cadillac Seville (imported to Sweden sometime during the 80's)
Controller/code version: MS1 V2.2, running MS-extra 029, fuel only (original spark computer/HEI in use)
Hardware: Ford Sierra injectors (167 cc/min at 2,5 bar), Bosch temp sensors (modern GM characteristics), Ford TPS (mounted to the standard Cadillac TB, using an adapter plate). Standard Cadillac fuel pumps, fuel lines etc. but the fuel rail is spaced upwards to allow for the longer injectors. Injectors also needed smaller O-rings to fit intake and fuel rail. MS relay board. Using the tacho output from the HEI distributor for rpm signal to MS.

I made a new wiring loom for the EFI since the old wires were a bit doubtful in some areas. Nice and simple install really.

The winter is coming so at the moment it's only base tuned to be semi mobile. But it seems to work :-)
