Can someone help explain to ME where R29/R30 is i assume its in the 16 pin chip netres


found information below that will allow me to fire TBI every DRP

PFI/TBI MODE SELECTION
To set the PFI/TBI modes just described, the MEM/CAL assembly resistors R29 and R30 must be set to proper values. These two resistors form a voltage divider network between a 5 volt line, VRFD, and ground which enables decoding the REFHI input signal according to the mode selected.

The divided input voltage level and its relationship to the injector operating mode is shown in the table below, MEM/CAL Mode Selection.

The mode selected also has a critical relationship to ignition spark events, EST output, as described in Ignition, Spark and Dwell Control.


MEM/CAL
Mode Selection
Application Mode Input Voltage(R29/R30 ratio) Frequency Of Injection
1. Alternating TBI 2/3 VRFD + 10% ALT. Every REF pulse
2. Single Injector TBI VRFD + 0% - 10% Every REF pulse

which pin is VRFD ... looks like i need to build a little voltage divider ANY help PLS

 

I answered this in your other post, in case you missed it......
