Just like the title says... didn't dawn on me - I've got Block Learn Multiplier (BLM) output via the 160Baud '302 on byte 19 - but no mention of INT in the ALDL datastream.
Wow.
Is that a 8192 only thing? I looked in TunerPro RT's 160Baud 6E datastream, and hey - no INT. 8192 does, though.
BLM = long term fuel trim, correct? so a BLM of 140 @ idle = rich?

BLM being 140 , your car is lean...
Less than 128 BLM your car is rich and trying to pull fuel out, over 128 your car is lean and its trying to add fuel back in.'

Odd... I get a BLM of 140 @ idle, with a 1.03 voltage on the O2, and the WB02 reading between 12.8:1 and 13.2:1

Do a search for stoich, blm, 128, o2 constants, etc....
128 does not always equal 14.7, especially at idle once u start playing with cams and have reversion and self egr at idle etc,etc.
Some good info here on it though.
Try searching under datamaster and monitor lol It took me to some good ones lol
