oh boy well, I know nothing about this, on my S/C everything has a separate circuit only fuel injection, I think EGR is gone, Transmission, limiter, etc, about a dozen things were deleted on my ECM.one thing, the ECm would prime fuel pump as turn key on and start. after it was flashed it would take good 20 seconds or more to prime and start, so I have an Alfa steering column, and one of the levers on the right, when is moved down, has no power,( no need it something to do with wipers on Alfa but the rest works wipers, light ), so I hooked up power to that wire before I start the engine I move the lever for 2 seconds it'll activate the fuel pump and fist klick the engine starts. I can leave it on or move up by then ECM takes over for the fuel pump. I have to tell you, many many things were instructed by Jim Dinner who would come to my house.
