Thank you for the response. My motor and computer are from a wrecked 91 ZR1. To the best of my knowledge, no recalibration has ever been done. The only engine modification is the installation of long tube headers. I removed the cover from the prom and found the following information: DELCO/AXFK/0277 and 060075.The instructions from the engine wiring harness kit said to simply ground the one terminal that would have otherwise run to the switch if full power all the time was desired. The motor starts fine, idles fine but is extremely rich. Any advice?
