The most important question is: What system do I want? GM Based system. First came ECMs-Engine control management- Then PCMs-Powertrain(eng/tran) control management- These allow full control of engine and electronic transmissions. They can be MPFI-multiport, SFI-sequentialport, CPI-centralport or TBI-Throttlebody fuel injection. TBI What parts do I need? What Throttle Body adapter do I need? 454 factory adapter cautions MPFI-- Multiport fuel injection MPFI discussion 1227730 install Option 1-Modifying the TBI/CPI 16168625/16197427/16196395/16156930/16245358 PCM for MPFI. First install-Batch fire with 7427 PCM MPFI Manifolds Drilling an IH Only aluminum manifold Drilling a stock 345/392 cast manifold Installing the manifold Then we need to be able to wire all these parts up so: What wires do I need to use for the 1227747 ECM? How about the later TBI PCM 16168625/16197427/16196395/16156930/16245358 PCM IH Holley Distributor stock specs and rebuild. And then.... what distributor can I use? (for FI and carbs) NO- your pertronix will not work for the EFI conversion Duraspark conversion using a Holley distr for carbs and EFI-Saves you $500 for HEI Duraspark conversion option 2 Mopar conversion using the Holley Distr Prestolite-Mopar EFI conversion GM/IH Hybrid DUI/large cap HEI/Stock conversion Duraspark conversion using a Prestolite dist HEI for the IH 6 cyl Stock IH/Chevy Stovebolt 6 cyl Delco distr conversion AMC V8 Duraspark Distributor AMC 258 6 cyl Duraspark distr for carb and EFI IH MV series distributor conversion Once the initial installation is done then you need to perform these initial setup procedures. I built the Distributor, so what do I hook it to? (Ignition upgrades for FI and carbs) Ignition Systems FUEL SYSTEMS In Tank Pumps Dual Tanks How about Dual Fuel options 304 Dual fuel conversion What about those aftermarket Systems? MSD Atomic TBI MISC Can you walk me through a fuel injection conversion step by step? Thread in progress!! What about Fuel Injection on a 4 cyl? Another 4 cyl TBIOnly this one has DIS- distributorless ignition 4 Cyl MPFI- Just cause we can! TBI for the inline 6cyl crowd How do I remove Injectors or make my Fuel Pressure Regulator adjustable? Vacuum fuel pressure regulator conversion for TBI What VSS can I use? Hot Fuel Module-What is it? Basic Trouble Shooting TUNING AND PROGRAMMING CHIPS How to remove the chip from the plastic carrier....Video! Chip Programming options How do I get the data out of the computer and then change it? Basic chip adjustments Basic timing table How do I install the Moates EEPROM adapter? How to convert from the 2732 EPROM to a 27SF512 EEPROM LINKS Where else can I go to get more information and reference material? What if I still have questions because you didn't do a very good job of explaining it? Take a look at this Video, it may help!
