Default What are you guys using for boost control? and EM integration ?

I'm looking into what boost control I'm going to use with my emanage ultimate.

And exactly how plug and play the boost and wideband o2 controler is going to be...

What boost controlers are you guys using? and how exactly does it integrate into your EM maps ??

also, with the emanage ultimate, I assume I just wire the wideband o2 right up the brain and it will do the rest ??

I'm using a Blitz SBC ID electronic boost controller i bought used on these boards for $200. I definately noticed quicker spool up times compared to my manual controller. I read an article in Sport Compact where they tested all the different brands of electronic boost controllers on the same car and same dyno in 1 day, and they raved about the Blitz SBC ID. They said it made the quickest spool up time, and was the easiest to use, so I went with it. It is really easy to use and I have rock solid boost at whatever i set it to. I couldn't be happier.

It was pretty easy to just set the boost and it would hit it. Your EMU map will have either Boost vs. RPM, or MAF voltage vs. RPM, so you just set the boost level and tune to that level. I started with the contoller set to wastegate pressure (10 psi) and tuned it, then went to 12 psi and tuned it, and worked my way up slowly. When your map is set to Boost vs. RPM, the cursor will just go deeper in the map as you turn up the boost each time.

The wideband was a little bit tricky. You need the wideband harness from greddy, and it has two wires, white and gray. My wideband controller had a white wire which was the 0-5v analog output signal. So the white from the controller went to the white on the greddy harness, and the gray on the greddy harness needs to go to ground. Then you need to go into the Emu software and select which wideband you have from the drop down menu. Only problem was they didn't have the PLX M-300 on their menu, so I had to pick a different brand that had the same range as the PLX. I looked at the manual that came with the PLX and it said it was 10-20, meaning the AFR was 10:1 at 0 volts and 20:1 at 5 volts. In the greddy drop down menu, each brand of wideband has the range listed also, so i just picked one with 10-20 and it worked perfect. I started the data logger so it was recording real time, and compared it to the readout on my wideband controller and they were exactly the same.

Hope this helps.

I think you can download the install files from:
http://www.mohdparts.com/

After downloading and installing it, you can look at everything that the EMU can do.
They also have tons more of info on the EMU.
