Just started squirting (and sparking)
 

I have my MS in (standalone) and everything is running, but my idle is super high (2000rpm) and I can't seem to get my PLX WBO2 to read correctly. What settings should I use if there's anyone out there that has one? I think it would be the same if not similar to the LC-1.

Basic Settings -> Exhaust Gas Settings -> EGO Sensor Type: Wide band, EGO Switch Point (v): 2.332, Ignition Events: 16, Controller Step Size: 1, Controller Authority 15, Active Above Coolant Temp (C): 65, Active Above RPM: 1100, EGO Correction Step Counter: mSec

The only other thing I did was change to PLX in the configurator. Am I missing anything or is my AFR just really lean right now? I'm using the defaults for everything provided by diyautotune.

I unplugged my IAC and idle went down to a more normal level. Is it broken, or just configured completely wrong? I just punched in what diyautotune had.

tune your VE fuel table.

So my PLX should be set up right with those settings? I just thought it was strange to be all the way lean on a base map. My gauge doesn't correspond to what MS says, but it's only a NB gauge. Guess I should check the grounding.

what does the PLX output? 10:1 - 20:1 @ 0-5v?

if not you may have to modify the .ini to make the MS match what the PLX outputs.

your last statement confuses me. does your gauge read off a NB and then the MS sees the WB signal?

The MS ini file has a setting for the LC-1 and PLX 10-20:1, it's working, my brain is just backwards. I was thinking lower number = lean and higher = rich. I guess yesterday was a longer day than I thought. I just need to tune this.

yes

As far as the IAC goes though, I guess I need to calibrate it? I basically just want to make sure the board is 100% functional before I blame it on settings. It turns on and goes to 2000rpm, then kicks off and goes down to normal after warmup, so I THINK it's working properly and just needs settings. Just want to confirm with someone in the know.

start maniplulating your VE fuel table, once you get it into the sweet spot, between 14.7:1-13.5:1 it will idle lower and stedy.
