I was able to get the AEM Wideband installed in the car. The gauge isn’t properly mounted yet, but I am getting good AFR readings which I’m using to work on tuning the fuel map a bit. In order to enable Tuner Studio to utilize the wideband, I had to change the Project Properties to specify the right wideband sensor and then I had to modify c:\program files\efianalytics\tunerstudioms\inc\lamdasensors.ini to include:
#elif AEM_LINEAR
afr = { 10.0 + (egoADC * 0.0392157) }
lambda = { afr / 14.7 }
TargetAFR = { 10.0 + (afrtarget * 0.0392157 ) }
TargetLambda = { TargetAFR / 14.7 }
Turns out I was running waaaay rich, so VE Analyze Live has been real busy slowing the injectors down a bit.
I also swapped the Forge BOV out and put the stock surge valve back in. There’s a little bit of a difference, but it still sounds like there’s some compressor surge.
