1998 Vortec Timing Table (Black Box Computer) Open / Closed Throttle ONLY!
I've copied / pasted a 1998 Vortec Timing Table from EFI Live into a Microsoft Excel spreadsheet. I've adapted the (Black Box Computer) factory Vortec timing tables for other GM ECM's / PCM's for a SBC TBI engine that has been updated to Vortec heads.:thumbsup: I've only posted the FACTORY BLACK BOX COMPUTER TIMING TABLES for Open Throttle and Closed Throttle. In Total, The Factory Black Box Computer has 21 Timing Tables and Spark Parameters!!!!!!!!!!!!!:yikes:
