Hi 930/66,
It's been almost a year since any updates on this. Very nice build. I have one question. From looking at the pics in post 107 pg 6 it looks like you mounted the Bosch WBO2 in the driver side bank secondary pre-turbo? There are typically two problems when doing this, the wide band won't last at pre-turbo temps (unless you go to an NTK) and the AFR readings are skewed to the rich side since the sensor output is affected by back pressure in the header. As the back-pressure increases, the AFR gauge reads less than actual so if the AFR is reading 12.5 the actual AFR will be leaner, not desirable. Just wondering how that location has worked out?. With EFI a compensation table is normally used that adjusts the WBO2 output based on back pressure, not possible with CIS. Have you had any problems? I have a build in mind that will require two WBO2 pre-turbo but it will be EFI.
