S2000 EGRL Input

Some S2000 ECUs do not have the circuitry to support the EGRL (B12) input.  To check if your ECU has the circuitry, remove the ECU and open the case.

If component C20 is tan capacitor, EGRL is supported.  If component C20 is a black resistor ‘102’, then EGRL is not supported.  In this case, the ECU may be modified by Hondata to support the input.
