On this topic, long ago there was a rather simple stand alone interceptor device with an AFR dial ( you put in the cab)
The kit had a wideband which you put in place of your narrow 02 and then converted it to narrowband for your ECU to be happy, you could then adjust where the narrow band AFR thought STOICH was centered on using the dial.
Anyone remember what this plug was? I can't seem to find the thread. (it wasn't a simple efie)
Also has anyone ever noticed narrow band sensors that do not center on stoich?
Just curious.
Thanx
