Wideband and boost controller
 

Just wondering what everyone is running for these.

I know you can get the solenoid for boost and just control using the EMS.

What about widebands? Are you monitoring with a digital gauge?

the wideband fail-safe is a nice option, monitor boost and AFR/lambda on one gauge that you can also use for logging

that looks like a good option, but I already have a boost gauge, just need to control it. now if that could also act as a boost controller, then I would be all in.

Any good MAC or 3 port boost control solenoid should work if you already have a standalone. As for EBC (electronic boost controllers), I'm not too familiar with them but any name brand one should work well. AEM, HKS, GReddy, Apex'i, etc.

I also have the AEM Wideband FailSafe on my car it it works great, plus as mentioned before you can log with it. But just a standard AEM Wideband will work great, people also like the Innovative brand.

Really any Wideband will work with the AEM. You will just hookup the wideband 0-5v wire to the stock O2 sensor ecu wire and calibrate it in AEMpro. I have the PLX WB with the DM-200 LCD gauge and I like it.

As for EBC, don't bother. The AEM has all the boost control features you could ever want/need. You can set up boost per VSS, Hi/Low, and RPM/TPS. So you could have a Hi/low switch for boost on the fly, assuming you have a Series 1 ems. On the Series 2 you can adjust boost based on gears or even a 12 position switch.

So I can run the wideband straight to the ECU, I don't need to go through an intermediate gauge first?

Yes and no. You don't have to use a gauge but you will need a controller to power and convert the output signal to 0-5v.
for instance withe innovate LC-2 Wideband controller. It powers the O2 sensor and has 2 0-5v outputs. you could read the AFR's directly from your Laptop if you wanted to.

However, its a really good Idea to have an AFR gauge to keep an eye on things while driving as opposed to looking over at the laptop.

Is monitoring AFR really that important after you tune the car though?

I know a lot of people run the gauge, but I know several people who don't use a gauge because you just end up staring at it the entire time you're driving.

I'm trying to keep the interior as de-cluttered as possible, but if it really is the smart/safe thing to do for the rotary, I guess I could do a column mount single gauge.

How important? thats something only you can decide. I mean I don't need one but I have one because I like having that peace of mind that if something doesn't feel right when driving or if it starts idling weird its the first thing I look at...:scratch:*shit!, what is my afr at?*

I am using a MAC 3 port boost solenoid on my Series 1 with a simple Hi/Lo switch. Works great and completely dynamic.

I'll have to look into that. It appears to be the same as the AEM branded one, just about half the price.

I found this AFR gauge that is pretty small. Should be able to conceal it easily, but still be able to read it if necessary.

I have the AEM true boost gauge wired into my AEM v1 to control boost but my AEM wide band is not wired into the ecu. Is there a DIY for this? I would feel a lot better about my AFR using the wideband instead of the stock O2 sensor.

Cut the wire for your stock o2 sensor and solder the analog wire for the WB to it. Then adjust in aem pro as per instructions.

Yes, you can splice into the wire for the O2 sensor in the engine compartment or you can tap into the wire directly into the ECU. In the Series I AEM notes it talks about using the O2 gain. You do not want to do this and you need to keep the gain at 0. You will need to move the O2#1 cal table up or down to match the Wideband gauge to the laptop data.

Awesome, thanks for the help! And while I am being spoon fed here, does anyone know what pin it is on the ECU harness that I need to cut?

Running the AEM inline wideband straight to the EMS along with the AEM 3 port boost solenoid (failed on me, now using Grimmspeed Manual)

I figured I'd keep it all aem. Using the AEM truboost as a boost gauge, the AEM series II to control boost by gear with a hi/low switch, and AEM UEGO wideband for logging and closed loop O2 fedback.
