Tuning Question about BLM and AFR
Hi all
im in the progress of getting my 396 tuned, and noticed the following....
Datamaster shows an Blm of about 138, my WbO2 shows an AFR 13.5-14 to 1
the oxygen sensor is at passenger side, the WbO2 sensor on drivers...anyways, the injectors should work the same, also the pressure in the fuel line should be equal
any comments to this situation?`
regards

BLM shows a little lean and the WB is showing a tad rich. If possible I would switch the NB and WB O2's and see how they read. If you can't do that, just get the WB a little closer to 14.7 and see what happens with the BLM's...also what is the INT doing?
