Flak Posted August 31, 2022 Share Posted August 31, 2022 Hello all, The owner before me converted from efi to dual carbs. I plan on adding back the efi with this intake/fuel rail from protunerz: https://protunerz.com/collections/frontpage/products/l-series-intake-manifold-fuel-rail-75mm-throttle-body Along with a high pressure fuel pump, what else do I need to convert back to efi? Did he have to take out the whole ecu? Quote Link to comment Share on other sites More sharing options...
NewZed Posted August 31, 2022 Share Posted August 31, 2022 Download an FSM and open the Engine Fuel chapter. You'll need all of the parts shown there if you want to go back to stock EFI. You need a lot more parts than what's in that ad. AFM, injectors, sensors, ECU, etc. Or aftermarket engine management. Make a list of what you have now. It's a complex project. Be careful with those aftermarket parts. Many of them have never been tested on a running engine before they're put on the market. They look neat but might not perform.

steelcurtain13 Posted September 13, 2022 Share Posted September 13, 2022 I used a FAST EFI system, works great. Got rid of all the EGR stuff and it came with everything you need to hook up to the stuff you are looking at buying. Zcardepot sells the kit with all the parts.
