Weird data from LS2 ..

[Garry]

I met up with some Corvette folks today, and offered to run a quick scan of his LS2 ... well, it seemed to work fine, but I noticed the desired AFR was acting weird, in essence being a copy (albeit lower line) of the TP ... I used the PID-File "default LS2 Metric" that comes with EFILive ...

Garry, that looks quite strange...

exactly what I was thinking ... ;)

I know this is not obvious, but GM didn't seem to provide an AFR PID for the EE38/E67 controllers (well not one we could find/use). So Ross made a DMA PID for the E38/E67 controllers:

For E40 controllers, use GM.AFR_B
For E38/E67 controllers, use GM.AFRATIO_DMA
