BCS testing data

I forget what the impedence of the stock BCS is off the top of my head but it won't hurt to install a 1 ohm,1/2 watt resistor in series. It won't negatively affect the performance IMO, especially since the voltage drop is less than 0.4 volts to the BCS so the latency won't suffer. I find that having the inline resistor helps regulate the power spikes sometimes assosiated with coils. I would imagine the ECU output circuit has a resistor in parallel already to help with this though. Basically the same as a fuel injector driver circuit.

Wassup. :-) Thanks for sending the MAC back then. My Prodrive 3-port that I bought is sitting in a box too. Seems that GM does at least one thing right. Yeah, the BCS benchtop testing setup is completely dismantled, but I can put it back together within a few hours. I have one of the OEM EGR 3-ports I'm going to be testing for Bryan soon. Wouldn't be much extra work to test the GrimmSpeed if someone was willing to send one.
MAC has a variety of options with their 3-ports, and I believe that GrimmSpeed had some custom specs, so I suspect it does behave a bit differently than the AEM MAC.

PM me the address to send it to, and when e.g. which week(s) you think you would need it for testing, if you are still willing test the GrimmSpeed BCS.

I haven't been excited enough to make the time to test the OEM EGR 3-port solenoid, but I love putting advertising to the test, so I will definitely make time to test your GrimmSpeed and the OEM EGR 3-port. PMing you with my snail mail address in just a moment. Thanks.

I finally used a OEM 3 port. It runs a really odd WGDC curve for the same amount of boost other 3 ports run.
I'd will be very interested in seeing the tech testing of it.

Do you have an update regarding when you might be able to make time to test the GrimmSpeed and OEM EGR 3-port BCSs, incl. some comparisons to the GM BCS?
I too am interested to see the results.
