Subject: Re: VSS signal to CCM by Matatk on 2016/1/31 20:40:03 I can't answer your question directly. I found this related to the VSS signal: 1. The two-pulse (2000 pulses per mile) square wave (D.C current or direct current) used on all TBI engines thru 1992, all computer-controlled-carbureted engines, and on 1985-1989 TPI engines. 2. A four-pulse (4000 pulses per mile) sine-wave (A.C. current or alternating current) signal is required by the 1990-1993 TPI, 1992-1993 LT1 engines, and 1990-1993 Camaro 3.1/3.4 V6 engines. On 3rd Gen it is recommended to use a buffer box. This might be something to look into: http://www.thirdgen.org/forums/dfi-ec ... -fast-xfi-vss-wiring.html |
