Evo 9 OEM M800 (GM Delco 3 port BCS)

[aalzuhair]

Hello there,

If I would to install a GM Delco 3 port boost control solenoid to replace the stock solenoid, would I need to install a 10ohms 2 watts resistor, or can I do without?

Noting that the stock boost solenoid has between 29~36ohms resistance and the GM one has 24ohms resistance, thus the 10ohms resistor

Thanks,

Az

There is no need for the resistor, just set the frequency to 20 Hz and connect it to the same wiring as the original valve.
