GM BCS users: Are you using a 10 ohm resistor in series with BCS?
GM boost control solenoid users: Are you using a 10 ohm resistor in series with the GM BCS to match the circuit resistance to the OEM BCS? If no, how long have you been running without a resistor?

I have the resistor installed.
|
I've been using a 10ohm resistor since I installed the GM BCS originally. I suspect most folks running a GM BCS have wired it up per this thread's advice, so you may have some difficulty locating someone running it without.
|
Definitely with 10 ohm resistor.

I used whatever resistor was spec'd in the thread :)

I have a resistor. Its so cheap and easy, why risk it?
|
I use to run a 10ohm resistor, when i had the GM solenoid hooked up. According to the subie guys using the resistor could cause some voltage drop slightly.
|
I run a 10 ohm 1 watt resistor

I'm running the AEM/MAC with a resistor.
The reason he is asking is because yes, it can cause voltage drop. This means that your 70hz might actually be something like 60hz with the solenoid not having enough power to fully switch sometimes at high speed/frequency. |

we have a couple track cars running without for over a year with no issues.
|
So would it be better to run without the resistor?
|
What is the coil resistance of the GM BCS anyways? I tested my stock BCS and its 33 ohms. I would assume that the outut voltage on such a circuit would be regulated. I dont even know the maximum voltage of this output, anyone know?

A 10ohm resistor will not cause much of any voltage drop, but will reduce the current thru the solenoid, prolonging its life.
