What if 1227727 with Ededlbrock (PN#3574) 14.4 Ohm Saturated Injectors?
Subscribe
I'd like to use ECM 1227727 with an Edelbrock Multi-port EFI system (PN#3506). The injectors used for the Multi-port injection system are Edelbrock (PN#3574) which according to some of Edelbrock parts suppliers are; 19 lbs. - hour 14.4 ~ 14.9 Ohms Impedance, 12V Saturated Circuit Driver Injectors.
The Edelbrock 3506 system was originally designed to retro-fit Multi-Port injection to GM TBI Pickups which mostly had ECM 1227747.
From the searches I done, I've found most 1227727 TPI injectors had 16 Ohm Impedance Injectors?
Four 14.4 Ohm injectors in parallel = 3.6 Ohms
Four 16.0 Ohm injectors in parallel = 4.0 Ohms
Has anyone succesfully used the Edelbrock 3574 injectors with the 1227727 ECM?
I've seen the Dynamic EFI Embedded Lockers (EBL) system ... but I already have a good 1227727 ECM and Custom TPI Wiring Harne$$ paid for. I really can't afford to go with the Embedded Locker system.

Not an issue, the '7727 will work with the Edelbrock system. Can use injectors with a resistance down to 12 ohms each (max of 8 of course).
