Thread: EFI Connection 58x

  1. #1

    Default EFI Connection 58x

    I installed an EFI Connection 58x crank and 1x cam sensor in my SBC. I can't find any info on how to setup the tune. I have in custom LSx 58x. I have no clue on Inductive Delay and I know Timing Offset will be set to make the timing mark for TDC. I have cam sensor set to Single Pulse and Digital Falling. Am I missing something? Thanks in advance.

    Ask EFI Connection for a copy of the instructions if they didn't come with your parts. Or look at some Holley instructions for similar parts.

    EFI Connections said to ask Holley. Seems they sell products, but don't know how they work. No instructions included in box pertaining to ECU input. Thanks, I'll look at the page you sent me.

    I'd do a System Log and look at the crank & cam signals. Andrew

    A System Log to see cam & crank sensors. I watched a video how to do it. Since EFI Connection is no help, I don't know if it's an LSx 58x or in customs 58x and choose the Single Pulse cam sync. I have tried both and get the 1 mil. On Diag #1. #6 & #7 are supposed to be 1.00. Well mine are 0.00 when you read them at the bottom left of screen. On a datalog it reads #6 101 kPa & #7 reads 29.7 lb/hr. So I have no idea what the heck is going on.
